Benchmark: Using Sensors To Study Public Space, Mario A. Giampieri, Sarah Williams, Wenfei Xu, Hayrettin Gunc, Christine M. Langston, Dennis C. Harvey

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Efforts have been made throughout history to measure how people use public space. This research seeks to integrate a range of sensor technologies to automate analysis of pedestrian usage of public space. A range of environmental sensors, image recognition utilities, and open-source software are combined to create a system to measure in detail how people use public space, with the intention of serving as a tool for creating better public spaces in the future. This framework is part of a broader effort to offer organizations and individuals methods and data to inform place-making interventions at multiple scales in conjunction with …

The tool has broad utility for applications related to outdoor thermal comfort, urban energy consumption, climate change mitigation etc. It includes tools to: enable users to input atmospheric and surface data from multiple sources, prepare meteorological data for use in urban areas, undertake simulations and consider scenarios, and …


The Utility Of Beautiful Visualizations, Laura Tateosian, Reza Amindarbari, Christopher Healey, Pavel Kosik, James Enns Sep 2017

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 Sep 2017

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 Sep 2017

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 Sep 2017

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 …


Geopoll - Integrate Cartographic Questions In Web Forms, Polls Or Surveys, Adrien Bigler, Olivier Ertz, Daniel Rappo, Sarah Composto, Florent Joerin, Maude Luggen Risse Sep 2017

Geopoll - Integrate Cartographic Questions In Web Forms, Polls Or Surveys, Adrien Bigler, Olivier Ertz, Daniel Rappo, Sarah Composto, Florent Joerin, Maude Luggen Risse

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Most of the web forms, polls or surveys are composed with classical input fields (check boxes, radio buttons, select lists, etc.) and a lot of standards web forms builders or services (e.g. Typeform, WuFoo, Google Forms, Survey Monkey, etc.) help to build and deploy them. Nowadays, offering a text area to catch a ZIP code or a select list to point out a country remains the best way to explicitly collect geospatial data. But what about mapping interfaces to integrate cartographic questions and/or cartographic answers as a more suitable solution? How to let form’s respondents indicate in which area(s) they …

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

This study aims to examine the relationship between temperature and precipitation as climatic factors and the vegetation characteristics in Forêt Classée de la Mondah (Gabon). A pixel based spatial analysis procedure with QGIS was used to extract vegetation characteristics from MODIS on Terra, NDVI band, data from February 2000 to December 2015, while temperature and precipitation were monitored from January 1980 to December 2015 to highlight climate fluctuations in the study area. Two regression analyses were conducted : one between temperature and NDVI and the other one between precipitation and NDVI. Results showed that temperature and precipitation did not vary …


A New Spatial Approach For Efficient Transformation Of Equality - Generalized Tsp To Tsp, Mohammed Zia, Ziyadin Cakir, Dursun Zafer Seker Sep 2017

A New Spatial Approach For Efficient Transformation Of Equality - Generalized Tsp To Tsp, Mohammed Zia, Ziyadin Cakir, Dursun Zafer Seker

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

The Equality - Generalized Travelling Salesman Problem (E-GTSP) asks to find a Hamiltonian cycle visiting each group exactly once, where each group represents a type of visiting node. This can represent a range of combinatorial optimization problem of NP-hard type like planning, logistics, etc. Its solution requires transformation of E-GTSP to TSP before solving it using a given TSP solver. This paper presents 5 different search-algorithms for optimal transformation which considers spatial spread of nodes of each group. Algorithms are tested over 15 cities with different street-network’s fractal-dimension for 5 instances of group-counts each. It’s observed that the R-Search algorithm, …

Desert Pool {If Every Desert Was Once A Sea}, Karen Miranda Abel Sep 2017

Desert Pool {If Every Desert Was Once A Sea}, Karen Miranda Abel

The Goose

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.

No Time To Defend The Pre-Post-Truth World, Richard Pickard Aug 2017

No Time To Defend The Pre-Post-Truth World, Richard Pickard

The Goose

As much as the "post-truth" needs to be challenged and countered, the humanities can play a crucial role in keeping alive the understanding that the pre-post-truth world ought not to be conserved, but transformed positively. After all, this was a world marked by accelerating anthropogenic climate change, by ongoing and transforming colonialism, by racism as a structural pillar, by misogyny and sexism. The environmental humanities must retain their historic radical mission, and they will founder if they surrender such a potential.


Defending Truths, Restoring Worlds, Bart H. Welling Aug 2017

Defending Truths, Restoring Worlds, Bart H. Welling

The Goose

The "post" in "post-truth" is premature, and also assigns too much importance to Brexit and the victory of Donald Trump in the US. Worst of all, it can foster the impression that people like Brexit voters and Trump supporters are irredeemably exiled in "alternative fact" bubbles beyond the reach of science, rational thought, and common decency. We have to find ways to work productively with these kinds of citizens, instead of merely condemning them, if we want to trigger both a worldwide alternative energy revolution and the revolution in politics and economics that a truly just and sustainable energy transition …


What Rises Above The White Noise: The Possibility Of Hearing Truth In A Post-Truth World, Harriet Fraser, Rob Fraser Aug 2017

What Rises Above The White Noise: The Possibility Of Hearing Truth In A Post-Truth World, Harriet Fraser, Rob Fraser

The Goose

This installation in a valley in the UK’s Lake District National Park taps into the idea of communication, the problem of apparent fact and post-truth, and which voices are being heard when it comes to standing up for the environment. In consideration of post-truth and the confusion between fact and fiction, particularly with regard to issues about environment, this art installation explores the possibility of clarity in voices that are heard above the white noise of facts, partial truths and information overload. It is a site-specific installation, created around a single tree and a rapidly flowing river in the Lake …


(Another) Battle In The Clouds, Mél Hogan Aug 2017

(Another) Battle In The Clouds, Mél Hogan

The Goose

At age ten, in 1918, Rachel Carson entered a writing contest and won. In "Battle in the Clouds", Carson wrote about the sky as a battlefield, where a soldier’s life is momentarily spared because of an act of bravery undeniable even by his enemies. They watch in awe and admiration rather than shoot. For my reimagining of the present as womb rather than grave, I reflect on the current use of the cloud in “cloud computing” to discuss the role of the internet and its material infrastructures in shaping earthly possibilities. I imagine the pace and place of awe rather …


Reading Speculative Futures In A Post-Truth World, Rachel Webb Jekanowski Aug 2017

Reading Speculative Futures In A Post-Truth World, Rachel Webb Jekanowski

The Goose

Faced with the threat of a “post-truth” world and a widening chasm of exchange between climate change deniers and environmentalists, I argue that future-orientated literary and media speculative fictions—which I term “speculative futures”—offer a means of building lines of communication across social and political divisions. This thought piece on “The Environmental Humanities in a Post-Truth World” mediates upon the potentiality of speculative futures as theory, social bridge-building, and pedagogical tool. Speculative fictions (especially those that address environmental justice, and anti-colonial and feminist politics) use storytelling and future imaginaries to challenge political falsehoods and imagine more ecological, de-colonized futures.


Towards Food Service Sustainability In Suburban Environments By Optimally Locating Shared Anaerobic Digester Units, Rebecca Loraamm, Joni Downs, Robert Alonso Bair, Daniel Yeh Aug 2017

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 …
