QGIS is an Open Source Geographic Information System (GIS) and is one of the more popular and use friendly open source GIS packages available. Formerly known as JUMP GIS, the application can read shapefiles and GML format files. OpenJUMP GIS is an open source GIS written in Java through a collaborative effort by volunteers. The application is built using Microsoft’s. MapWindow GIS is open source GIS application that can be extended through plugins. Platforms: Windows, Macintosh, Linux, UNIX GvSIG is an open source GIS application written in Java. Platforms: Linux, Macintosh, Sun Solaris, Silicon Graphics Irix, HP-UX, DEC-Alpha, and Windows OS GRASS is a raster-based GIS, vector GIS, image processing system, graphics production system, data management system, and spatial modeling system.

GRASS is probably the most well-known open source and original GIS software applications. Geographic Resources Analysis Support System (GRASS) is the public domain GIS software application originally developed by the US Government. GMT is a free, public-domain collection of ~60 UNIX tools that allow users to manipulate (x,y) and (x,y,z) data sets (including filtering, trend fitting, gridding, projecting, etc.) and produce Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots through contour maps to artificially illuminated surfaces and 3-D perspective views in black and white, gray tone, hachure patterns, and 24-bit color. This application was developed at the Faculty of Geographical Sciences of the Utrecht University in the Netherlands. Open Source GIS SoftwareįlowMap is a freeware application designed to analyze and display flow data.

To learn GIS using open source software, read Sid Feygin’s article How to Go from GIS Novice to Pro without Spending a Dimewhich provides tips and resources. Population open source web mapping includes OpenLayers and MapBuilder, widely used due to their simplicity and accessibility. Outside of the three major language groups, open source web mapping is another group.

SharpMap and WorldWind are the most popular of these applications.

The third most influential group of Open Source GIS would be the one that integrates applications that use “. GeoTools, Geoserve, and OpenMap, are among the most popular open source GIS in this group of JAVA tools. Other operators, like Union or Buffer, which are very hard to code, are offered in this group making it very appreciated by GIS developers. JTS, central library for the Java GIS development, offers some geospatial functions that allow to compare objects and return a boolean true/false result indicating the existence (or absence) of any questioned spatial relationship. The second group of Open Source GIS would be the ones that use JAVA as the implementation language. Popular “C” based open source GIS software applications include GRASS, a project started in 1982 by the US Army but is now open source, and QGIS (otherwise known as Quantum GIS). The libraries in the “C” group, from the base infrastructure, and include some capabilities like coordinate reprojection that make them very useful and popular. This is the more mature of the groups of open source GIS, probably for the simple reason that is the group that has been working on GIS software applications the longest and has a long history of resuse of code. The first group would be the group that uses “C” language for its implementation. Three main groups of open source GIS (outside of web GIS) in terms of programming languages are: “C” languages, Java, and. Open source GIS programs are based on different base programming languages. Open source projects typically are worked on by a community of volunteer programmers.
