Imports gridded data into Microsoft MapPoint, to produce attractive data maps that resemble contour maps.

Input data consists of a value that is defined for various (gridded) geographic coordinates. Common text output formats such as CSV are supported.

Can handle imperfect data, holes, re-gridding, etc. Can be used to import such attributes as pollution data, seismic hazard, geological information, customer/population distribution, etc.
Data can be interpolated to different grid spacings if required. Polygon optimization algorithms reduce the drawing time, as well as GridImp''s cpu & memory requirements.

Various text formats supported using space, tab, or comma separators with both Unix and DOS/Windows newline conventions. Data coordinates can be longitude,latitude coordinates; custom linear coordinates; or UK Ordnance Survey Grid References.

GridImp can add data to an existing map or template; allowing it to be used with such products as the Single State Mapper or other MapPoint add-ins.

Predefined or user-defined color schemes can be used. These can include transparent gaps as well as attractive color gradations.

Version 2.3 adds: Support for Windows Vista (32 bit).

Version v2.2 adds: Support for Microsoft MapPoint 2006.

Version v2.0 adds: Support for Ordnance Survey Grid References; Support for custom linear grids; support for existing map files; ability to force MapPoint garbage collection for large maps (reduces MapPoint's memory requirements, and increases speed).

Requires: Microsoft MapPoint v2002, 2004, or 2006. Both MapPoint Europe and North America are supported.
