TRANSDAT. TRANSDAT performs Coordinate Transformations fast and with high accuracy. It supports thousands of world-wide Coordinate Systems, geodetic Reference Systems and Reference System Transitions (datum shifts), user-defined systems, 2D/3D transformations, INSPIRE, NTv2, EPSG, GPS, continental drift and more. It reads and writes the file systems Text, CSV, SDF, dBase, Arc-Shape, Arc-Generate, KML and others. TRANSDAT - Version 17.31 - Latest update on 11 April 2014 The latest important changes Canada with many CRS and NTv2 completed.
Brief description Besides the usual Geographic Information Systems (GIS) are a large number of geodetic applications and data collections, which are used for recording, editing and presentation of spatial data. TRANSDAT is a professional computer program for world-wide Coordinate Transformations between national and country-specific Coordinate and Reference Systems with high precision and good performance: Blue Marble Coordinate Conversion. Coordinate reference support and accurate transformation is one of the most important elements of any functional GIS. Geospatial mapping must include an accurate representation of the earth in order to provide accurate scientific information for sound decision making. As evidenced in both the GeoCalc software developer toolkit and the Geographic Calculator, Blue Marble's coordinate transformation software is known worldwide as the standard for accuracy and reliability.
Not only does this technology provide intuitive interfaces for setting up complicated transformations, late binding datum transformations, direct connections to the OGP's EPSG registry, survey seismic formats, batch coordinate transformations and all types of file format translation, but the Geographic Calculator combined with the Blue Marble desktop allows GIS managers and Geodesists to manage, assign and control the coordinate transformation project work for all GIS users including those using ArcGIS.
Eye4Software Coordinate Calculator. Introduction A map datum is a reference from which measurements are made. In geodesy, a geodetic or map datum is a set of reference points on the earth's surface against which position measurements are made, and (often) an associated model of the shape of the earth (reference ellipsoid) to define a geographic coordinate system. Some examples of geodetic datums are: NAD27, NAD83, ED50 etc... Parameters An map datum can be defined in the Eye4Software Coordinate Calculator or Eye4Software GPS Toolkit using 7 parameters, also called Helmert-7 parameters: Scale Factor; Translation X ( tX ); Translation Y ( tY ); Translation Z ( tZ ); Rotation X ( rX ); Rotation Y ( rY ); Rotation Z ( rZ ); Also an ellipsoid has to be specified when a map datum is defined.
List of map datums used around the world Eye4Software Coordinate Calculator Using the Eye4Software Coordinate Calculator, you can convert coordinates from one map datum to another easily, using the user friendly user interface. FME Spatial Data Transformation.
