Solving a surveying problem by using R and QGIS - Setting out of a land expropriation zone

Abstract: Abstract.Application of the open source software when resolving geodetic issues provides limitless possibilities. The present paper will showcase a methodology for setting out of engineering projects through a combination of GIS (Geographic Information System) software QGIS and R software environment. The link between QGIS and R had been established using Sextante toolbox, which significantly extends possibilities for a QGIS application, by establishing link to the other "powerful" tools, such as R. Test examp… Show more

“…QGIS (QGIS Development Team, ) is a free and open‐source GIS. It provides a graphical user interface to the Geospatial Data Abstraction Library (GDAL/OGR contributors, ), supports Geographic Resources Analysis Support System (GRASS Development Team, ) and System for Automated Geoscientific Analyses (Conrad et al, ) geoprocessing libraries, and makes extensive use of Python in user‐contributed plug‐ins (Pejović et al, ). QGIS is a project of the Open Source Geospatial Foundation (Goel et al, ), which is an umbrella organization for the development of open‐source geospatial software.…”

“…Possibilita aos usuários criar mapas multicamadas, utilizando várias projeções cartográficas. Estes mapas podem ter várias finalidades como analises ambientais, urbanas, demográficas, dentre outras (PejoviĆ et al, 2014). "QGIS suporta um grande número de formatos de dados matriciais e vetoriais que são facilmente adicionados usando a arquitetura de plug-in" (Censipam, s/d, p. 5; apud Almeida, 2011, p. 174).…”

“…Isto é possível dado que o QGIS é baseado em uma biblioteca de código aberto. A administração do projeto é feita por um grupo de técnicos e especialistas em geoprocessamento, pelo Project Steering Commitee (Manghi, Cavallini, Neves, 2011); (Oliani, Paiva, Antunes, 2012); (PejoviĆ et al, 2014). Algumas das extensões QGIS como GDAL, GRASS GIS, PostGIS e PostgreSQL são consideradas importantes, visto que aumentaram significativamente sua usabilidade (PejoviĆ et al, 2014).…”
