New Listings Free GIS Software - Python, FWTools, PrimaGIS, Spatial Index

Most of these newly listed GIS software and tools are related to Python geographic programming.

Cartographic Objects for Zope 0.7 features enhanced labeling of features, catalog-like search for features from data stores, and improved management interface for data stores.

FWTools is a set of Open Source GIS binaries for Windows (win32) and Linux (x86 32bit) systems produced by me, Frank Warmerdam (ie. FW). The kits are intended to be easy for end users to install and get going with. No fudzing with building from source, or having to collect lots of interrelated packages.

OpenEV is a software library and application for viewing and analysing raster and vector geospatial data. OpenEV is used by private companies, universities, governments and non-profit organizations around the world.

PrimaGIS is a mapping solution meant primarily as a spatial extension for Archetypes based objects. The idea is to allow existing Archetypes based objects to be presented on predefined maps and allow users to easily access this spatial information in relation to the primary information of the objects. PrimaGIS is not a standalone application, but builds on top of Mapserver, Python Cartographic Library (PCL) and Cartographic Objects for Zope (ZCO).

Python is a remarkably powerful dynamic programming language that is used in a wide variety of application domains.

Python Cartographic Library (PCL) - Python is rapidly becoming the language of choice for GIS programming. At the fore of this movement have been AVPython, OpenEV, and Python bindings for GDAL and OGR. On their heels, ESRI now distributes Python with Arc 9 and other commercial vendors are following suit.

Spatial Index: This package provides a general framework for developing spatial indices. Currently it defines generic interfaces, provides simple main memory and disk based storage managers and a robust implementation of an R*-tree, an MVR-tree and a TPR-tree.

I Hope these prove useful to you. 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. More to come!
