Best datum software for free download

TRANSDAT Geosoftware executes coordinate transformations and geodetic datum shifts between lots of coordinate and reference systems of Germany, Europe, America, Australia and world wide in high quality and with high performance: 1. The German Coordinate and Reference Systems of the old and new Federal Countries including the 40 Prussian Soldner Land Registers and Soldner Berlin and Munic. 2. The current and many historical Coordinate and Reference Systems of all States of the European Union (EU) including the eastern extension from April 2004 and other European Systems. 3. The US- and Canadian State Plane Coordinate Systems (SPCS) on NAD27 and NAD83 and other Coordinate and Reference Systems of the North American Continent. 4. The Coordinate and Reference Systems of the Australian Continent. 5. A lot of Coordinate and Reference Systems of other Continents. 6. All world-wide used Coordinate and Reference Systems. You find a complete list of the coordinate and reference systems supported by the program in the internet or after downloading of the programs free test version. Apart from the given world-wide and state-specific systems also your own coordinate systems and geodetic reference systems can be defined with Helmert (Bursa / Wolf, ISO19111) or Molodenski parameters. Calculations can be performed with coordinates entered directly, loaded from files in various formats (Text, dBase, ArcShape and ArcGenerate) or passed through batch processing. ArcShape files can be viewed with the program intern Shape Viewer. A programmable GPS interface makes possible to read coordinates from a low cost GPS antenna into a notebook. The program can be run on network, where clients are installed automaticly. The program has user-selectable German or English language interface and comes with extensive bi-language online help.

ORTWIN is a program for the state-wide inquiry of the localities in Germany. It finds postal zip codes, telephone pre selections, coordinates, it performs perimeter searches and distance calculations. The program determines municipal codes, local center points, car license codes, topographic maps and more. It arranges localities hierarchically into the structures federal country, administrative district, rural district, town, municipality, local quarter and domicile. In a radius around a place or around a postal code area covered localities and postal areas can be clearly represented by a comfortable perimeter search. They can also be arranged in a list, stored as a file and printed. For the local inquiries and perimeter searches a data base with more than 60.000 geo coded localities is available. The program represents local data, determined by local inquiries and perimeter searches, in graphic overviews and data lists. The program supports conversions between different coordinate systems and the distance calculation between the places. It calculates with Gauss Krueger coordinates and Geographic Coordinates referring to the Potsdam Datum (Bessel ellipsoid with central point Rauenberg). It also works with UTM coordinates, which refer to the datum ETRS89 (GRS80 / WGS84, geocentric). The functionality of the program is described in a detailed electronic manual. The program can be run on most common networks and it is possible to use Terminal Services on WINDOWS Servers. The client installations are done automatically.

TOPOWIN is a state-wide register of the German Topographic Cartographies, the German Basic Cartography and of localities with geo references in different coordinate systems. It is also a topographic information system. In the division of planning and execution of economical and scientific projects frequently topographic documents are used. The program TOPOWIN makes information available of the official topographic cartographies and the German Basic Cartography from the entire national territory in suitable graphic views. It accomplishes different coordinate transformations and inquiries. The program was developed under co-operation of the land surveying authorities of many German Federal States. For the first time in the previous version TOPO (for DOS) and later in TOPOWIN state-wide topographic information were arranged for the data technical evaluation. The program is for consulting engineers, planning authorities and users of topographic maps a useful and versatile tool. The topographical maps of different standards, required for a project, can be determined by the complaint of known parameters or by the direct selection from overview graphics and from sorted lists. By the investigation of topographical records on the basis of known places, a data base with more then 60.000 places and residential districts is available. The program TOPOWIN calculates with Gauss Krueger coordinates and Geographic Coordinates refering to the Potsdam Datum (Bessel ellipsoid with central point Rauenberg). It also works with UTM coordinates and UTMRef coordinates in the NATO standard, which refer to the datum ETRS89 (GRS80 / WGS84, geocentric).
