Free GIS and Graphics Software - NCAR, NRDB, OGR, OpenDMTP, OpenLayers

Free GIS Software Programs Part 7

NCAR Graphics Software is comprised of a library containing Fortran/C utilities for drawing contours, maps, vectors, streamlines, weather maps, surfaces, histograms, X/Y plots, annotations, an ANSI/ISO standard version of GKS, a math library containing a collection of 1,2,3-D interpolators and approximators, applications for displaying, editing, and manipulating graphical output, map databases, many FORTRAN and C examples.

NRDB (Natural Resources Database) is a free database and mapping application for developing and distributing environmental databases. Its aim is to provide people in developing countries with a powerful yet simple tool to assist in the managing of their own resources.

OGR Simple Features Library is a C++ open source library (and commandline tools) providing read (and sometimes write) access to a variety of vector file formats including ESRI Shapefiles, and Mapinfo mid/mif and TAB formats.

OpenDMTP, is a protocol and framework that allows bi-directional data communications between servers and devices (clients) over the Internet and similar networks. OpenDMTP is particularly geared towards Location-based information (LBS) such as GPS, as well as temperature and other data collected in remote-monitoring devices.

OpenGTS - The "Open GPS Tracking System" is the first available open source project designed specifically to provide web-based GPS tracking services for a "fleet" of vehicles.

OpenLayers is a pure JavaScript library for displaying map data in most modern web browsers, with no server-side dependencies. OpenLayers implements a (still-developing) JavaScript API for building rich web-based geographic applications, similar to the Google Maps and MSN Virtual Earth APIs, with one important difference -- OpenLayers is Free Software, developed for and by the Open Source software community.

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.
