RSGIS Unix Pages

Here are a few GIS/RS tools designed for the Unix platform:
 

PROJ
This package offers commandline tools and a library for performing respective forward and inverse transformation of cartographic data to or from cartesian data with a wide range of selectable projection functions.

GMT (The Generic Mapping Tools)
GMT is a collection of about 60 UNIX tools that allow users to manipulate (x,y) and (x,y,z) data sets (including filtering, trend fitting, gridding, projecting, etc.) and produce Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots through contour maps to artificially illuminated surfaces and 3-D perspective views in black and white, gray tone, hachure patterns, and 24-bit color. GMT supports 25 common map projections plus linear, log, and power scaling, and comes with support data such as coastlines, rivers, and political boundaries.

iGMT (Interactive Mapping of Geoscientific Datasets)
iGMT provides a graphical user interface and was built using the Tcl/Tk computer language. Besides supplying a user-friendly way of handling GMT, iGMT comes with built-in support for many different geoscientific data sets, such as topography, gravity, seafloor age, hypocenter catalogues, plate boundary files, hotspot lists, CMT solutions, etc.

GEOTRANS (Geographic Translator)
GEOTRANS  is an application program which allows users to easily convert geographic coordinates among a wide variety of coordinate systems, map projections, and datums. GEOTRANS runs in both Microsoft Windows (95/98/NT) and UNIX Motif environments.

OGR
The 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.

GpsDrive
Gpsdrive is a map-based navigation system. It displays your position provided from a NMEA-capable GPS receiver. The maps are autoselected for the best resolution, depending of your position, and the displayed image can be zoomed. Maps can be downloaded from the Internet. The program provides information about speed, direction, bearing, arrival time, actual position, and target position. Speech output is also available.

Gen2shp
Implemented in Avenue, can be directly incorporated into AV projects. Converts 2D or 3D ASCII data from one or more generate format text files to one or more (multi-part) shapefiles. Available as Extension or just Scripts.

JEEPS
The JEEPS library is intended as both a library and a development system for GPS and related software. It consists of documented C functions for communication with GARMIN GPS devices and for post-processing of the information received. The library also contains functions for conversion of datums using Molodensky and cartesian methods and mapping functions including transverse mercator projections. The UTM coordinate system is implemented as are other more parochial systems including the UK Ordnance Survey national grid (with map codes). Eighteen map projections and their inverses are given. NMEA data capture routines are included. An application (program) is distributed with the library in order to show the library functionality and how to use it.

PostGIS
PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend for GIS.
PostGIS/PostgreSQL includes the following functionality:
-Simple Features as defined by the OpenGIS Consortium (OGC)
-Support for Well-Known Text and Well-Known Binary representations of GIS objects
-Fast spatial indexing using GiST
-Geospatial analysis functions
-PostgreSQL JDBC extension objects corresponding to the geometries
-Support for OGC access functions as defined by the Simple Features Specification

wayp2shp
A simple C-program which can read a Waypoint+ file. The data in this file will be converted to shapefile format.

g3DGMV (3D Graphical Map Viewer)
The g3DGMV program was designed as a free viewer for Digital Elevation Model (DEM ) and Digital Line Graphs (DLG ) maps. These maps are rendered by g3DGMV as 3D images that can be manipulated by the user and view from different angles.

kdem
kdem is a program for displaying USGS DEM's. If offes a number of interesting features:
-Highly interactive, giving you realtime feedback for nearly every operation.
-Completely "interruptible". You never have to wait for rendering to complete before doing something else.
-Reads both the older text format, and the new Spatial Data Transfer Standard (SDTS) datasets.
-Shaders control the colors used to draw the DEM, and many of them are user configurable.
-kdem can generate red/blue anaglyphs (images that appear to have depth when viewed through red/blue glasses).
-Supports the SpaceTec Space Orb 360 game controller, a "6 degrees of freedom" input device.

GIS Viewer
GIS Viewer 4.0 is a web-based Java tool for displaying and manipulating layers of geographical points and vectors, and raster data such as maps and images.

gpspoint
Program to download and upload waypoints, routes, and tracks to and from your GPS device. Upload and download is possible via the GARMIN interface. Current position obtainable via the NMEA Interface, supported by most GPS devices.

gpsutils
The gpsutils package covers some small applications to capture and convert data from a Garmin GPS receiver. These are based on a included more general GPS library (in C).

GPS3D
gps3d is a set of utilities that lets you manipulate your GPS from your Linux/Win32 box, and visualize the output in 3D. At the moment, it only supports NMEA capable devices. If you do not own a GPS device, you can still use gps3d to play interactively with a 3D texture mapped model of earth.

Grid
Grid is a perl extension for raster-based GIS work. The tool is developed to support hydrologic and water resources GIS work.

APR-Parser
Perl script to extract info from ArcView apr files into a database to ease indexing and searching. Documents the apr format.
