Geographic Translator : MSP Geotrans 3.2

 MSP Geotrans 3.2

Geotrans 3.2 has been released. Geotrans is the coordinate conversion application or a geographic translator program among a wide variety of coordinate systems, map projections, and datums. Geotrans runs in Microsoft Windows, LINUX and UNIX environments. GEOTRANS can also be used to convert large numbers of coordinates contained in either text files (.txt) or comma separated values (.csv).

To convert a set of coordinates, simply select the coordinate system or map projection, the datum, in which your coordinates are defined, then enter the source coordinates, select the coordinate system or map projection, and the datum, to which you want the coordinates to be converted, and click on the Convert button. The resulting coordinates will be displayed.

ISO/TC 211

ISO/TC211


ISO/TC 211 is a standard technical committee formed within ISO, tasked with covering the areas of digital geographic information (such as used by geographic information systems) and geomatics. It is responsible for preparation of a series of International Standards and Technical Specifications numbered in the range starting at 19101
Scope:

ISO/TC 211 is concerned with the standardization in the field of digital geographic information. This work aims to establish a structured set of standards for information concerning objects or phenomena that are directly or indirectly associated with a location relative to the Earth.
Project specification areas within the ISO/TC 211 technical committee include:
  • Simple Features access
  • Reference models
  • Spatial and temporal schemas
  • Location-based services
  • Metadata
  • Web feature and map services
  • Classification systems
The ISO/TC 211 work is closely related to the efforts of the Open Geospatial Consortium. ISO/TC 211 have numerous liaisons with other organizations that often results in identical or nearly identical standards often being adopted by both organizations.

Free and Open Source GIS Resources


Bundled Software

Sometimes it's just easier to go one place. Here are some places worth going.

FWTools http://fwtools.maptools.org/

Frank Warmerdam maintains most of the open source infrastructure for handling projections and file formats. It's handy to know what and where they are, since they are often prerequisites for installing other packages: proj4 and GDAL (pronounced "goodle", rhymes with noodle).
FWTools includes pre-compiled binaries for both Windows and Linux of GDAL and proj4, along with the web map server MapServer and raster-oriented desktop OpenEV. Frank contributes to or maintains all these packages.

GIS Knoppix http://www.sourcepole.com/sources/software/gis-knoppix/

GIS Knoppix is a self-booting Linux CD set up to be a sort of Linux workstation on a CD. It has office productivity tools, like OpenOffice , along with a full set of GIS tools: desktop, web map server, etc.

MapServer for Windows (MS4W) http://www.maptools.org/ms4w/index.phtml

MS4W installs pre-compiled windows binaries that comprise a complete development environment for making applications with the MapServer web map server.

Enterprise GIS: Spatially Enabled Databases

PostGIS http://postgis.refractions.net/

PostGIS is the most commonly used back-end database in free software. Most of the desktops listed are PostGIS clients, as well as the MapServer and GeoServer web map servers.

MySQL http://www.mysql.com/

MySQL has spatial extensions , and is supported in both the MapServer and GeoServer web map servers.

Desktops

GRASS http://grass.ibiblio.org/index.html

GRASS , the Geographic Resources Analysis Support System, is a long-standing, complete GIS system. It was originally written in Unix, and runs best in Linux or Unix of some kind. Although the interfaces have recently improved it still has a learning curve. The GRASS community is enormous, and world-wide, with commensurate support resources.

JUMP http://www.jump-project.org/

JUMP supposedly works everywhere, but is much more windows oriented. Has a nice graphical user interface (GUI), and includes conflation tools. It requires SUN's Java Virtual Machine (JVM).

OpenEV http://openev.sourceforge.net/

OpenEV is a raster-oriented viewer with some editing capability. Can display vectors, and create simple shapefiles. Most vector capabilities (snapping, etc.) are not present.

Quantum GIS (QGIS) http://qgis.org/

QGIS is mostly a viewer, with some fairly new editing capabilities. It is more mature on the Linux side of the house, but does have a windows preview release. It is extremely simple to operate, and creates configuration files for the MapServer web map server.

Thuban http://thuban.intevation.org/

Thuban is a viewer, and is definitely cross-platform (Windows, Linux, etc.). It's based on Python.

UDig http://udig.refractions.net/

UDig is still in development, but may suit your needs even in its current form. It's designed to expand on JUMP functionality, and conform to important Open Geospatial Consortium standards. Refractions Research is planning to sell support for uDig.

Web Map Servers

There are quite a variety of these. The two listed below have the most developed capabilities.

MapServer http://mapserver.gis.umn.edu/

MapServer has a very simple set-up and is economical with system resources. It is widely supported and integrated with other packages. The MapServer community has an annual conference.

GeoServer http://geoserver.sourceforge.net/html/index.php

GeoServer is Java-based, and has a fairly complex set-up. It is widely supported, and integrated with other packages.
