Free GIS and Geospatial Software Part 9
SAGA - System for Automated Geoscientific Analyses - is a hybrid GIS software. The first objective of SAGA is to give (geo-)scientists an effective but easy learnable platform for the implementation of geoscientific methods, which is achieved by SAGA's unique Application Programming Interface (API).
sdts2d is a Translator for SDTS DEM Files. The sdts2dem program translates USGS DEM files from SDTS format to "native" format. It is in the public domain and may be freely redistributed.
SDTS Public Domain Software - Although these programs have been used by the USGS, no warranty, expressed or implied, is made by the USGS as to the accuracy and functioning of the programs and related program material, nor shall the fact of distribution constitute any such warranty, and no responsibility is assumed by the USGS in connection therewith.
SPRING is a state-of-the-art GIS and remote sensing image processing system with an object-oriented data model which provides for the integration of raster and vector data representations in a single environment.
Thuban is an interactive geographic data viewer. Main features are its cross-plattform GUI, extensability and flexibility for deriving individual GIS applications. Thuban is implemented with wxPython which allows its GUI to blend in with desktop on different platforms.
TNTmips Free is a free version of TNTmips Pro for small-scale projects. TNTmips Free is not a demo, but a large, full-featured geospatial analysis software package. TNTmips Free is the same program as TNTmips Pro except that the license to use it free-of-charge limits the size, number, and complexity of the geodata layers you can use in your project.
Hope these prove useful. If you are new to GIS, check out the Learn2Map GIS Tutorial and Atlas. We have more free GIS software available and there is plenty of free data and shapefiles that will work with these programs.
