Housing Conditions In Kano, Nigeria: A Qualitative Assessment Of Adequacy, Abdulqadir Bello, Istvan Egresi 2017 Fatih University

Housing Conditions In Kano, Nigeria: A Qualitative Assessment Of Adequacy, Abdulqadir Bello, Istvan Egresi

Istvan Egresi

 Many studies have attempted to assess the qualitative adequacy of housing in Nigeria. However, most of these studies focus either on slums or on public housing projects. There are very few empirical studies that examine and compare the qualitative adequacy of housing belonging to different population groups and from different neighborhoods in a city. The purpose of this study is to assess the housing quality in the (entire) city of Kano, Nigeria and to examine the disparities in housing adequacy across the city based on four factors: neighborhood density level, location of the neighborhood relative to the old city wall ...


Making A Case For Social Innovation As A Structural Counterpart To Public Participation In Regional Planning, Manju A. Adikesavan 2017 The Graduate Center, City University of New York

Making A Case For Social Innovation As A Structural Counterpart To Public Participation In Regional Planning, Manju A. Adikesavan

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

Multi-locational living – working, shopping, playing, learning and commuting across administrative and, sometimes even political boundaries is an essential aspect of metropolitan living. Although it is anticipated that everyday experiences of the physical, social and economic inter-connectedness between urban communities and peri-urban hinterlands would automatically engender a regional outlook in planning and governance, it is currently not the case. In the New York City region, a lived regional experience does not translate into support for a regional governance structure.

While strong legislative support has ensured the public its rightful place within metropolitan regional planning, it has regrettably bred a procedural focus ...

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 ...

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 ...

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 ...

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 ...

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 ...


Optimizing Spatiotemporal Analysis Using Multidimensional Indexing With Geowave, Richard Fecher, Michael A. Whitby 2017 Digital Globe

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

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 ...

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 significantly ...


A New Spatial Approach For Efficient Transformation Of Equality - Generalized Tsp To Tsp, Mohammed Zia, Ziyadin Cakir, Dursun Zafer Seker 2017 National Innovation & Research Center for Geographical Information Technologies, Turkey

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 ...
