A Cutting-Plane Method For Contiguity-Constrained Spatial Aggregation, Johannes Oehrlein, Jan-Henrik Haunert
A Cutting-Plane Method For Contiguity-Constrained Spatial Aggregation, Johannes Oehrlein, Jan-Henrik Haunert
Journal of Spatial Information Science
Aggregating areas into larger regions is a common problem in spatial planning, geographic information science, and cartography. The aim can be to group administrative areal units into electoral districts or sales territories, in which case the problem is known as districting. In other cases, area aggregation is seen as a generalization or visualization task, which aims to reveal spatial patterns in geographic data. Despite these different motivations, the heart of the problem is the same: given a planar partition, one wants to aggregate several elements of this partition to regions. These often must have or exceed a particular size, be …
Insight Provenance For Spatiotemporal Visual Analytics: Theory, Review, And Guidelines, Andreas Hall, Paula Ahonen-Rainio, Kirsi Virrantaus
Insight Provenance For Spatiotemporal Visual Analytics: Theory, Review, And Guidelines, Andreas Hall, Paula Ahonen-Rainio, Kirsi Virrantaus
Journal of Spatial Information Science
Research on provenance, which focuses on different ways to describe and record the history of changes and advances made throughout an analysis process, is an integral part of visual analytics. This paper focuses on providing the provenance of insight and rationale through visualizations while emphasizing, first, that this entails a profound understanding of human cognition and reasoning and that, second, the special nature of spatiotemporal data needs to be acknowledged in this process. A recently proposed human reasoning framework for spatiotemporal analysis, and four guidelines for the creation of visualizations that provide the provenance of insight and rationale published in …

Vgi In Surveying Engineering: Introducing Collaborative Cloud Land Surveying, Ioannis Sofos, Vassilios Vescoukis, Maria Tsakiri
Journal of Spatial Information Science
olunteered geographic information (VGI) has enabled many innovative applications in various scientific fields. This paper introduces a new framework called "collaborative cloud-based land surveying" (CCLS) that uses VGI principles for data sharing among surveyor engineers to boost the productivity and improve the quality of their applications. A cloud-based spatio-temporal data repository is presented, aiming to facilitate the sharing of VGI among surveyor engineers. A fully-functional distributed software application has been developed and used to apply CCLS in a large-scale land surveying project run by the Greek Ministry of Culture, which involves the mapping of the historic center of Athens. Results …
Sailing: Cognition, Action, Communication, Thora Tenbrink, Frank Dylla
Sailing: Cognition, Action, Communication, Thora Tenbrink, Frank Dylla
Journal of Spatial Information Science
How do humans perceive and think about space, and how can this be represented adequately? For everyday activities such as locating objects or places, route planning, and the like, many insights have been gained over the past few decades, feeding into theories of spatial cognition and frameworks for spatial information science. In this paper, we explore sailing as a more specialized domain that has not yet been considered in this way, but has a lot to offer precisely because of its peculiarities. Sailing involves ways of thinking about space that are not normally required (or even acquired) in everyday life. …

Quantifying Space, Understanding Minds: A Visual Summary Approach, Mark Simpson, Kai-Florian Richter, Jan Oliver Wallgrün, Alexander Klippel
Journal of Spatial Information Science
This paper presents an illustrated, validated taxonomy of research that compares spatial measures to human behavior. Spatial measures quantify the spatial characteristics of environments, such as the centrality of intersections in a street network or the accessibility of a room in a building from all the other rooms. While spatial measures have been of interest to spatial sciences, they are also of importance in the behavioral sciences for use in modeling human behavior. A high correlation between values for spatial measures and specific behaviors can provide insights into an environment's legibility, and contribute to a deeper understanding of human spatial …
Modeling And Manipulating Spacetime Objects In A True 4d Model, Ken Arroyo Ohori, Hugo Ledoux, Jantien Stoter
Modeling And Manipulating Spacetime Objects In A True 4d Model, Ken Arroyo Ohori, Hugo Ledoux, Jantien Stoter
Journal of Spatial Information Science
The concept of spacetime has long been used in physics to refer to models that integrate 3D space and time as a single 4D continuum. We argue in this paper that it is also advantageous to use this concept in a practical geographic context by realizing a true 4D model, where time is modeled and implemented as a dimension in the same manner as the three spatial dimensions. Within this paper we focus on 4D vector objects, which can be implemented using dimension-independent data structures such as generalized maps. A 4D vector model allows us to create and manipulate models …
Cognitively Plausible Representations For The Alignment Of Sketch And Geo-Referenced Maps, Sahib Jan, Angela Schwering, Carl Schultz, Malumbo Chaka Chipofya
Cognitively Plausible Representations For The Alignment Of Sketch And Geo-Referenced Maps, Sahib Jan, Angela Schwering, Carl Schultz, Malumbo Chaka Chipofya
Journal of Spatial Information Science
In many geo-spatial applications, freehand sketch maps are considered as an intuitive way to collect user-generated spatial information. The task of automatically mapping information from such hand-drawn sketch maps to geo-referenced maps is known as the alignment task. Researchers have proposed various qualitative representations to capture distorted and generalized spatial information in sketch maps, however thus far the effectiveness of these representations has not been evaluated in the context of an alignment task. This paper empirically evaluates a set of cognitively plausible representations for alignment using real sketch maps collected from two different study areas with the corresponding geo-referenced maps. …
Topological Augmentation: A Step Forward For Qualitative Partition Reasoning, Matthew P. Dube
Topological Augmentation: A Step Forward For Qualitative Partition Reasoning, Matthew P. Dube
Journal of Spatial Information Science
The current state of the art for partition based qualitative spatial reasoning systems such as the 9-intersection, 9+-intersection, direction relation matrix, and peripheral direction relations is that of the binary set intersection — either empty or non-empty — conveying the intersection (or lack thereof) of an object in the sets deriving the partition. While such representations are sufficient for topological components of objects, these representations are not sufficient for various tasks in qualitative spatial reasoning (composition, representation transfer, converse, etc.) regarding partitions as tiles. Topological augmentation expands the current binary status quo into a system of assigning topological relations between …
Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba
Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba
International Journal of Speleology
Endemic and rare species as bioindicators of habitat vulnerability were used to develop protection and management plans for biotope prioritization (mainly islands habitats, lava tubes or groundwaters). Due to their narrow distribution, the endemic species (species confined to a restricted geographic area) are more susceptible to ecological disequilibrium and habitat loss than the widespread ones. Consequently, endemics become endangered in the context of ecological disturbance caused by anthropogenic pressure, making them suitable candidates to assess environmental preservation needs. Taking into consideration that most of the stygobitic and troglobitic species are endemic and confined to specific karst areas, based on their …

Collaborative Librarianship
As academic education and research increasingly take advantage of geospatial data and methodologies, we see a corresponding exponential growth in the number of available geospatial resources in the form of GIS datasets and scanned historical maps. However, users can experience difficulty finding these resources due to the unconnected multitude of platforms and clearinghouses that host them. Additionally, the resources are not always well described with web semantic metadata that facilitates discovery. In response to this challenge, The Big Ten Academic Alliance Geospatial Data Project began in 2015 to provide discoverability, facilitate access, and connect scholars to geospatial resources. Our project …

Using Osgeo Solutions For Local Development Systems Implementation. The Experience For The Northern Region Of Costa Rica, López-Villegas Oscar, Víquez-Acuña Oscar, Víquez-Acuña Leonardo
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Although some general definitions classify Spatial Data Infrastructures (SDI) as technological standards, institutional and even political agreements, which allow the discovery and use of geospatial information by users for different purposes [Kuhn 2005], computationally this platforms are valuable data repositories that should reach people efficiently and effectively for analysis and decision making on issues of collective interest. Costa Rica has several SDIs experiences at national level (SNIT - http://www.snitcr.go.cr), regional level (IDEHN - http://www.idehn.tec.ac.cr) or local/cantonal level (IDESCA - http://idesca.cr). Those infrastructures can facilitate access between geospatial information managers and their consumers through the implementation of particular software applications. The …

Kadaster Data Platform - Overview Archicture, Erwin Folmer, Wouter Beek
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The Dutch Cadastre is publishing its geospatial data assets as Linked Open Data through the Kadaster Data Platform (KDP). The KDP supports the following three Linked Data browsing paradigms: (1) graph navigation, (2) hierarchical browsing, and (3) faceted browsing. Graph navigation uses the graph-shape of the RDF datamodel, to display concepts and instances as nodes, and properties between them as edges between those nodes. Graph navigation works well for explorative browsing. For graph navigation the KDP uses LODView (http://lodview.it), an existing OSS. Hierarchical browsing uses the tree structure of the concept hierarchy in order to display the various classes and …

The Utility Of Beautiful Visualizations, Laura Tateosian, Reza Amindarbari, Christopher Healey, Pavel Kosik, James Enns
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Geovisualizations provide a means to inspect large complex multivariate datasets for information that would not otherwise be available with a tabular view or summary statistics alone. Aesthetically appealing visualizations can elicit prolonged exploration and encourage discovery. Creating data geovisualizations that are effective and beautiful is an important yet difficult challenge. Here we present a tool for rendering geovisualizations of continuous spatial data using the painterly techniques of impressionist-era artists. The techniques, which have been tested in controlled studies, vary the visual properties (e.g., hue, size, and tilt) of brush strokes to represent multiple data attributes simultaneously in each location. To …

Tracking 19th Century Late Blight From Archival Documents Using Text Analytics And Geoparsing, Laura Tateosian, Rachael Guenter, Yi-Peng Yang, Jean Ristaino
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
In 1845, Ireland's potato crop was struck by a devastating potato disease that killed Ireland’s crop caused devastation for seven years and led to mass starvation and emigration from the country. The cause of the potato destruction was a fungus-like plant pathogen. There are several theories about the origin of the disease and the source of the 19th century outbreaks. We use historical documents contemporary to that time to investigate spatial information that might inform these mysteries. We present methodologies for automatically extracting information from these voluminous data sources. We identify and map geographic locations that are proximate in the …

The Billion Object Platform (Bop): A System To Lower Barriers To Support Big, Streaming, Spatio-Temporal Data Sources, Devika Kakkar, Ben Lewis, David Smiley, Ariel Nunez
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
With funding from the Sloan Foundation and Harvard Dataverse, the Harvard Center for Geographic Analysis (CGA) has developed a big spatio-temporal data visualization platform called the Billion Object Platform or "BOP". The goal of the project is to lower barriers for scholars who wish to access large, streaming, spatio-temporal datasets. Since once archived, streaming data gets big fast, and since most GIS systems don't support interactive visualization of millions of objects, a new platform was needed. The BOP is loaded with the latest billion geo-tweets and is fed a real-time stream of about 1 million tweets per day. The CGA …
Optimizing Spatiotemporal Analysis Using Multidimensional Indexing With Geowave, Richard Fecher, Michael A. Whitby
Optimizing Spatiotemporal Analysis Using Multidimensional Indexing With Geowave, Richard Fecher, Michael A. Whitby
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The open source software GeoWave bridges the gap between geographic information systems and distributed computing. This is done by preserving locality of multidimensional data when indexing it into a single-dimensional key-value store, using space filling curves. This means that like values in each dimension are stored physically close together in the datastore. We demonstrate the efficiencies and benefits of the GeoWave indexing algorithm to store and query billions of spatiotemporal data points. We show how this indexing strategy can be used to reduce query and processing times by multiple orders of magnitude using publicly available taxi trip data published by …

Desert Pool {If every desert was once a sea} is a site-specific art project by Canadian artist Karen Miranda Abel completed in 2016 while artist-in-residence at Joya: arte + ecología, an arts-led research centre situated in an alpine desert within a national park in southern Spain. The elemental installation represents an envisioning of the ancient sea that occupied the Sierra de María-Los Vélez Natural Park millions of years before the current desert ecology, a time when its highest mountain peaks may have been islands.
Towards Food Service Sustainability In Suburban Environments By Optimally Locating Shared Anaerobic Digester Units, Rebecca Loraamm, Joni Downs, Robert Alonso Bair, Daniel Yeh
Towards Food Service Sustainability In Suburban Environments By Optimally Locating Shared Anaerobic Digester Units, Rebecca Loraamm, Joni Downs, Robert Alonso Bair, Daniel Yeh
Suburban Sustainability
Anaerobic digestion is an effective method for reducing food waste at the consumer level. Drawbacks associated with this strategy include high construction costs for multiple digester units and limited public awareness of the method’s commercial potential. Given the large scale problem of food waste, an approach establishing community partnerships between local businesses and primary schools is offered to combat the problem of food waste. Optimizing the placement of shared digester units enabling utilization by multiple stakeholders is the suggested mitigation method. This research explores application of the p-median problem to determine the set of optimal sites for shared anaerobic digester …
How To Enhance Interdisciplinary Competence—Interdisciplinary Problem-Based Learning Versus Interdisciplinary Project-Based Learning, Mirjam Brassler, Jan Dettmers
How To Enhance Interdisciplinary Competence—Interdisciplinary Problem-Based Learning Versus Interdisciplinary Project-Based Learning, Mirjam Brassler, Jan Dettmers
Interdisciplinary Journal of Problem-Based Learning
Interdisciplinary competence is important in academia for both employability and sustainable development. However, to date, there are no specific interdisciplinary education models and, naturally, no empirical studies to assess them. Since problem-based learning (PBL) and project-based learning (PjBL) are learning approaches that emphasize students’ collaboration, both pedagogies seem suitable to enhance students’ interdisciplinary competence. Based on the principle of constructive alignment and four instructional principles on interdisciplinary learning, this paper proposes that students profit more from interdisciplinary PBL (iPBL) than interdisciplinary PjBL (iPjBL). A pre-post study was conducted with a sample of 95 students participating in iPBL and 183 students …
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
DePaul Discoveries
While we have a comprehensive understanding of air pollutants, and their spatiotemporal characteristics across global, and even regional, scales, we are quite limited in our capacity to monitor neighborhood-scale emissions. The mobile monitoring of air pollution is a growing field, prospectively filling in these gaps while personalizing air quality-based tools and risk assessment. In the present study, we developed wearable sensors for particulate matter (PM); and through a citizen science approach, students of partnering Chicago schools monitored PM concentrations throughout their commutes over a five-day period. While their recorded findings would be used to explore the relationship between PM concentrations …
Spatial Analysis Of Tornado Warning System Understanding And Relationship With Tornado Occurrence, Chesnea A. Skeen
Spatial Analysis Of Tornado Warning System Understanding And Relationship With Tornado Occurrence, Chesnea A. Skeen
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
Tornadoes present a significant threat to life and property. The National Weather Service watch and warning system warns the public of tornadoes. If these warnings are not heeded by the public, the potential fatalities and destruction of property cannot be minimized. Thus, to prevent further loss of life and property, it is necessary to understand how the public understands the watch and warning system, as well as how they react. This paper aims to understand the correlation between understanding of watches and warnings and the occurrence of tornadoes, as well as how understanding varies spatially. Survey data were collected from …
Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets
Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets
Journal of Ocean and Coastal Economics
Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …
The Market Transfer Effect In The Hawaiian Longline Fishery: Why Correlation Does Not Imply Causation, Jason D. Scorse, Shaun Richards, Philip King
The Market Transfer Effect In The Hawaiian Longline Fishery: Why Correlation Does Not Imply Causation, Jason D. Scorse, Shaun Richards, Philip King
Journal of Ocean and Coastal Economics
A lot of discussion and controversy has surrounded whether the “market transfer” effect in the Hawaii longline swordfish fishery occurred during the swordfish closure of 2001-2004, because of its potential impacts on sea turtle mortality. The primary academic work in support of the market transfer effect during the closure is a paper by Rausser et al. (2009): “Unintended Consequences: The Spillover Effects of Common Property Regulations.” In this paper, the authors claim to find evidence in support of the market transfer hypothesis.To our knowledge, no analysis has yet been undertaken to assess whether this analysis is sound, and yet it …
Considerations Of Socio-Economic Input, Related Challenges And Recommendations For Ecosystem-Based Maritime Spatial Planning: A Review, Mavra Stithou
Considerations Of Socio-Economic Input, Related Challenges And Recommendations For Ecosystem-Based Maritime Spatial Planning: A Review, Mavra Stithou
Journal of Ocean and Coastal Economics
Socio-economics in an ecosystem-based Marine Spatial Planning (MSP) process cover a wide range from specifying socio-economic objectives, respective indicators, organising stakeholder engagement, to data, methods and tools (e.g., environmental valuation and cost-benefit analysis) for example to identify issues, assess ecosystem services, provide an insight on human behaviour and compare alternative marine plans with potentially competing goals. In addition, social principles such as that of social equity have an important role to play in achieving sustainability in marine management. However, the use of socio-economics in making the ecosystem-based MSP framework operational, poses certain challenges to researchers, regulators and policy-makers. The purpose …

Spatial features are stored in multiple formats (raster and vector) and resolutions (10-meter and 30-meter), while being in direct relationship with the table of attributes …
Development And Environmental Injustice In Malaysia: A Story Of Indigenous Resistance In Sarawak, May Tay '17
Development And Environmental Injustice In Malaysia: A Story Of Indigenous Resistance In Sarawak, May Tay '17
EnviroLab Asia
In 2008, the Federal Government of Malaysian announced an initiative to build 20,000 megawatts of mega dams along a 320km corridor in Sarawak. Named the Sarawak Corridor of Renewable Energy (SCORE), the scheme would create one of five regional development corridors throughout Malaysia, and was part of the government’s strategy to make the state of Sarawak ‘developed’ by 2020 through industrialization and renewable energy development (Recoda). Of the mega dams planned for construction by 2020, three have been completed, with construction for the others underway and the construction process frequently delayed by resistance from local indigenous communities. Indigenous tribe members …
