Presentation Outline

• Types of Open Source GIS
• Heavyware
• GRASS
• Lightware
• QGIS, JUMP, Thuban
• Spatially-enabled database
• PostGIS
• Internet Mapping
• MapServer, Geotools, uDIG

3
Types of Open Source GIS

• Heavyware
• Contains a compendium of various algorithms,
  tools and commands for vector and raster formats
• Lightware
• Comprise mostly of simple GIS viewers and light
  GIS applications
• Some features include a measure tool, overlaying
  support, simple geometry union, area and length
  computation buffering and attribute table display
  and manipulation

4
GRASS

• Oldest open source tool
• Initial development by the U.S. Army Construction
  Engineering Research Laboratory in 1982
• Official website at http//www.itc.it

5
QGIS

• Quantum GIS (QGIS) is a Geographic Information
  System (GIS) built for Linux/Unix
• QGIS supports vector, raster, and database
  formats. QGIS is licensed under the GNU Public
  License.
• Developed using QT and C language
• http//qgis.org

6
QGIS (contd.)

• Some of the major features include
• Support for spatially enabled PostGIS tables
• Support for shapefiles, ArcInfo coverages,
  Mapinfo, and other formats supported by OGR
• Raster support for a large number of formats
• Identify features
• Display attribute tables
• Select features
• GRASS Digitizing
• Feature labeling

JUMP

• The foundation of The JUMP-Project is a suite of
  free, open-source applications that provide an
  extensible API and graphic user interface (GUI)
  for viewing and manipulating spatial data-sets.
• Built on Java.
• http//jump-project.org

19
Thuban

• Thuban is an interactive geographic data viewer.
  It has been developed because there was no simple
  interactive viewer for geographic information
  available as Free Software.
• Thuban is written in Python and C and uses the
  wxWindows library allowing it to run on many
  different platforms, including GNU/Linux and
  Windows.
• http//thuban.intevation.org

20
Thuban (contd.)

• Support for
• Vector Data Support Shapefile, PostGIS Layer
• Raster Data Support GeoTIFF Layer
• Comfortable Map Navigation
• Object Identification and Annotation
• Legend Editor and Classification
• Table Queries and Joins
• Projection Support
• Printing and Vector Export
• API for Add-Ons (Extensions)
• Multi-Language Support English, French, German,
  Hungarian, Italian, Russian and Spanish
• User Manual (English)

PostGIS

• PostGIS is developed by Refractions Research Inc,
  as a spatial database technology research
  project.
• Refractions is a GIS and database consulting
  company in Victoria, British Columbia, Canada,
  specializing in data integration and custom
  software development.
• Spatially-enables PostgreSQL database
• http//www.refraction.net

28
MapServer

• MapServer is an OpenSource development
  environment for constructing spatially enabled
  Internet-web applications
• The software builds upon other popular OpenSource
  or freeware systems including Shapelib, FreeType,
  Proj.4, GDAL/OGR
• MapServer will run where most commercial systems
  won't or can't, on Linux/Apache platforms.
  MapServer is known to compile on most versions of
  UNIX/Linux, Microsoft Windows and even MacOS.

29
Geotools

• Geotools is an open source, Java GIS toolkit for
  developing standards compliant solutions.
• Its modular architecture allows extra
  functionality to be easily incorporated.
• Geotools aims to support Open Geospatial
  Consortium and other relevant standards as they
  are developed.
• GeoTools code is built using the latest Java
  tools and environments.
• http//www.geotools.org

uDIG

• The User-friendly Desktop Internet GIS for
  OpenGIS Spatial Data Infrastructures project (
  uDig) will create an open-source desktop GIS
  application, to make viewing, editing, and
  printing data from CGDI and local data sources
  simple for ordinary computer users.
• Built on Geotools
