Open Source C GIS Software

EPSILON is a powerful Open Source wavelet image compressor. The project is aimed on parallel and robust image processing.

A C library for reading and writing BSB format image files. Typically used for nautical charts, BSB image files use the .KAP extension and store cartographic information in addition to a run-length encoded raster image. Includes bsb2tif & tif2bsb tools.

A navigation system that displays street maps and tracks a vehicle using GPS. Specific locations can be selected by street address. Routes and tracks can be created, edited, and saved in GPX format. Runs on most POSIX systems, the iPAQ, and the Zaurus.

topography oriented GIS for cadastre maintenance fully configurable and totally autonomous (can be transfered to USB key) .

Preparation of GPS routes and analysis of GPS logs in the context of outdoor sports (biking, skiing, trecking, gliding, geocaching, mountaineering). Our hope is to have a multi platform, multi GPS file and map format software.

CAVOR is an engine for building apps that involve both graphic and text/numeric data. Primarily GIS is the initial focus, but consider also CAD, CASE, project management (eg PERT charts), and others. Built-in scripting, C API, also supports Tcl and Java.

Ertha is an open source GIS whose main focus is to guarantee easy extensibility and straightforward integration of custom modules. It provides basic geographic rendering and topologic analysis and exposes the main data structures loaded from shapefiles.

GPS moving map display with maps generated from US Census data in NAD83 (lat/lon) format. Includes road file generation software, gps daemon, and map display application written in GTK+

This is the project to create a GPS car navigator. This is something more than a typical "moving map" that you can do with Ozi, fmaps, Gnomad and others. The project aim is made route calculation, but not in a static way, as is doing by some web sites

OpenCarbox - a software suite providing an open source navigation media desktop for your car computer

A software assistant for manual stereo photo metrology, allowing the generation of 3D digital data (x,y,z) of objects of interest in stereo photos. 3D data can be used in CAD or other applications.

Use map data to plan hikes or explore new areas. Includes 3D maps of terrain rendered in real-time; trace trails across the terrain and get height verses distance profiles; tile together adjacent maps to create seamless map areas. Reads USGS SDTS files.

GeoSciPy is a set of C and Python functions that provide an API for all aspects of Geoscience and Remote Sensing Applications. Functions include reading/writing of many data formats, images, vectors, ..., and processing of images, vectors, ... including map projections, ... The library is written C, using HDF5 as the file format for storage of all remotely-sensed data and ancillary data, as well as processed data. The C functions assume a particular format for the HDF5 file contents, and provide functions for reading and writing data to such files. There is also a Python API that provides a procedural as well as an object-oriented interface to these functions. A Python GUI for interacting with such datasets is also part of the project. While there are other open-source GIS, and image-processing packages available, this one is designed to be comprehensive, work on 3 major platforms, user-extensible, fast, and able to handle huge datasets.

osgGtk is a library of C based Gtk+ and C++ based Gtk-- widgets to support OpenSceneGraph (OSG) applications. The library also includes several example applications such as osgviewerGtk and osgviewerGtkmm.

Viewpix allows the user to load all eleven bands of a Landsat 8 Level 1 data set into memory concurrently. You can scroll and view each band at full resolution. Change bands instantly with a single key press. Band 8 is 15 meters resolution, all other bands are 30m resolution. A 30m resolution gray scale scene is generated by Viewpix and is presented as band 12. Each Landsat 8 scene is roughly 190 X 180 kilometers. Viewpix was originally written as a simple platform to test GPU software on low end computer systems. This is the "lite" version of Viewpix as it has no cuda filters installed. Viewpix is written in C. It is tested on Ubuntu and Centos. It should work with most current Linux distributions. Viewpix runs efficiently on computers with modest CPU's such as low power mini-ITX boards. It is known to work nicely on Intel NUC, AMD A6 SOC , and NVIDIA TX2. A multiple core cpu, 8 GB ram, and a large capacity hard drive are suggested.

Gosm is and acronym for "Gtk OpenStreetMap tool". It displays either the standard Mapnik tiles from Openstreetmap or the Osmarender or Cyclemap tiles. It allows you to make tiles available for offline browsing and let's you create large images or PDFs
