The Eye4Software Coordinate Calculator is an easy to use desktop software tool, to convert coordinates from one coordinate system to another. It can also be used to convert coordinates between different horizontal map datums. The software can be used to convert a single coordinate, or to convert a batch of, for example, gps coordinates read from a comma separated file.

The software is shipped with a MS Access database containing almost any reference ellipsoid, map datum and coordinate system around. It is possible to modify the coordinate systems, reference ellipsoids and geodetic datum definitions stored in the database. You can also create user defined coordinate systems, reference ellipsoids and map datum definitions, so you can always extend the database.

The Eye4Software Coordinate Calculator can convert coordinates from one coordinate system to another using the following map projections:

- Lambert Conformal Conic (LCC) 1SP projection;
- Lambert Conformal Conic (LCC) 2SP projection;
- Lambert Conformal Conic West Orientated;
- Lambert Equal Area Conic projection;
- Transverse Mercator projection;
- Transverse Mercator South Orientated;
- Oblique Mercator projection;
- Hotine Oblique Mercator projection;
- Swiss Oblique Mercator projection;
- Oblique Stereographic projection;
- Polar Stereographic projection;
- Albers Equal Area Conic projection;
- Cassini Soldner projection;
- Mercator projection 1SP;
- Mercator projection 2SP;
- Polyconic projection;
- Gauss Kruger projection;
- UTM projection;
- Mollweide projection;
- Miller projection;
- Bonne projection;
- Sinusoidal projection;
- Cylindrical Equal Area projection;
- Eckert I projection;
- Eckert II projection;
- Eckert III projection;
- Eckert IV projection;
- Eckert V projection;
- Eckert VI projection;
- Krovak projection;
- Robinson projection;
- Plate Carree projection;
- Gall Stereographic projection;
- Winkel I projection;
- Equirectangular projection;
- Loximuthal projection;
- Azimuthal Equidistant projection;
- Hammer (Hammer-Aitoff) projection;

The following conversions are supported:

- Convert coordinates from latitude / longitude to a specific coordinate system using one of the map projections above;
- Convert coordinates from latitude / longitude to latitude / longitude, by translating to another map datum;
- Convert coordinates from a specific coordinate system to latitude/longitude;
- Convert coordinates from one coordinate system to another;
- Convert coordinates between different latitude / longitude formats.

To perform map datum conversion between NAD27 and NAD83, as well as between NAD83 and NAD83 HARN, it is possible to use a NADCON correction grid file. NADCON files, as well as HPGN / HARN files are shipped with the product, and the datum definitions to use NADCON are allready built-in.

The coordinate calculator supports datum conversions by using NTv2 (National Transformation version 2) grid files. Using these files, very accurate datum conversions can be performed. Because of the size, NTv2 grid files are not shipped with the product. For further reading, or to download grid files, please have a look at the NTv2 information page. NTv2 grids are mainly used in Canada, Australia, Great Britain (OSTN02), Germany (Beta2007), France and New-Zealand.

Using an easy-to-use wizard, you can translate data files from one coordinate system to another. The data formats supported include: ASCII text files, comma, space or tab separated files ( CSV or Excel ) and databases like MS Access files or ODBC data sources. All you have to do is to select source and destination coordinate system, select the fields and the software will perform the conversion.

Using the batch conversions wizard, it is also possible to convert an ESRI ShapeFile from one coordinate system to another. This may come in handy when you want, for instance, display 2 shape files at the same time, while one file has a different coordinate system. The function can also be used to convert files from WGS84 to a local map grid.
