Development Of A Qgis Plugin To Dasymetric Mapping, Nelson Mileu, Margarida Queirós
Development Of A Qgis Plugin To Dasymetric Mapping, Nelson Mileu, Margarida Queirós
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Demographic data is usually represented by choropleth map, where the statistical data is aggregated to areal units. This type of representation has several limitations associated with spatial analysis and distribution. A common alternative to display statistical data in meaningful spatial zones is the dasymetric mapping technique. Though dasymetric mapping has existed for many decades, the open source GIS tools to explore dasymetric mapping methods are scarce. In this paper, a Geographical Information System (GIS) open source application was developed in QGIS software that applies the dasymetric mapping method to the Portuguese Guimarães municipality 2011 Census block-group populations and using Corine …

Educating 21st Century Geospatial Technology Industryworkers With Open Source Software, Phillip Davis
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The global geospatial technology industry, in a study by UK-based Oxera commissioned by Google in January 2013, has been estimated at $150 USD billion to $270 USD billion per year ($110 billion euro to $199 billion euro). In a similar US-focused study, also commissioned by Google in 2013, the Boston Consulting Group (BCG) found the geospatial services industry employs approximately 500,000 people and generates around $75 (USD) billion in annual revenue ($55 billion euro). By any measure, the geospatial industry is large one, in both the US and globally. With this explosive growth, combined with the current generation of geospatial …

Adding Phylogenies To Qgis And Lifemapper For Evolutionary Studies Of Species Diversity, Jeffery A. Cavner, Aimee M. Stewart, Charles J. Grady, James H. Beach

Phylogenetic data from the “Tree of Life” have explicit spatial and temporal components when paired with species distribution and ecological data for testing contributions to biological community assembly at different geographic scales of species interaction. Important questions in biology about the degree of niche suitability and whether the history of a community’s assembly for an area can affect whether the species in a community are more or less phylogenetically related can be answered using several different spatially-filtered measures of phylogenetic diversity. Phylogenetic analyses which support the description of ecological processes are usually achieved in a handful of software libraries that …

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The importance of understanding the quality of data used in any GIS operation has increased significantly as a result of the advent of Free and Open Source (FOSS) tools and Open Data, which in turn have encouraged non-specialists to make use of GIS. Metadata (data about data) traditionally provides a description of this quality information and permits data curation, but it is frequently deemed as complex to create and maintain. Additionally, it is generally stored separately from the data, leading to issues where updates to the data are not reflected in the metadata and to users not being aware that …
Spatial Data Infrastructure Of The Plurinational State Of Bolivia - A Free And Democratic Sdi, Raul Fernando Molina Rodriguez, Sylvain Lesage
Spatial Data Infrastructure Of The Plurinational State Of Bolivia - A Free And Democratic Sdi, Raul Fernando Molina Rodriguez, Sylvain Lesage
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The Vice Presidency of the State, with the help of the GeoBolivia project, is building the Spatial Data Infrastructure of the Plurinational State of Bolivia (IDEEPB by its Spanish initials). The first phase of the project has already been completed. It consisted in implementing an infrastructure and a geoportal that nowadays gives access to the reference geographic information of Bolivia, through WMS, WFS, WCS and CSW services. The project is currently in its second phase dedicated to decentralizing the structure of IDE-EPB and promoting its use throughout the Bolivian State. The whole platform uses free software and open standards. As …

Analysing The Practical Feasibility Of Fossgis In Military Operations – A Cholera Outbreak Use Case, Susanna Jacoba Henrico, Serena Coetzee, Antony Cooper
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
Remaining ahead of the enemy in all circumstances is crucial to any military power. Geographic information systems (GIS) can provide the military commander with geospatial information about the theatre of war to assist with the planning and execution of a mission. Unfortunately, technology usually comes at a price. GIS is no exception. The cost of acquiring and maintaining GIS software licenses, as well as training staff in the use of the software, needs to be considered. The question arises whether open source software, which can be used without any software license expenses, is a feasible alternative in military operations. The …
