Free Geography Tools

A final roundup of Macintosh GIS progams that I missed in my original post (they’ll be added to that main listing shortly)

R – An open-source statistical analysis package. See this page for references on using it for geospatial analysis.

JGrass – A Java implementation of GRASS with emphasis on hydrological and geomorphological analysis; uses uDIG as a framework.

KyngChaos – Mentioned by several commenters; a source of Mac OS X builds of GIS-related software like GDAL/OGR and MapServer.

OSSIM:

OSSIM provides advanced geo-spatial image processing for remote sensing, photogrammetry, and Geographic Information Systems.  Backed by an active open source software development community, OSSIM solutions have been deployed on a number of critical commercial and government systems.

And going back to my listing of aerial/satellite imagery programs, which included OSSIM:

One – A through H
Two – I through M
Three – N through R
Four – S through Z
Five – GIS software

I found:

HEG – “… a tool developed to allow a user to reformat, re-project and perform stitching/mosaicing and subsetting operations on HDF-EOS objects. The output GeoTIFF file is ingestible into commonly used GIS applications. HEG will also write to HDF-EOS Grid & SWATH formats (i.e for Subsetting purposes) and native (or raw) binary. HEG presently works with MODIS (AQUA and TERRA), ASTER, MISR, AIRS, and AMSR-E HDF-EOS data sets.”

Comments and emails also referenced paid Mac GIS-related software:

Avenza – Add-ons like MAPublisher and Geographic Imager for Photoshop and Illustrator

Ortelius – Mapmaking software (coming soon).

TNTMips – Full version of the freeware TNTlite.
