Those looking to migrate their Microsoft MapPoint maps to the geospatial web may want to look at MPExporter, an add-in from Mapping-Tools.com.
MPExporter was designed to make it easy for users to export their data out of a MapPoint. Although it can write to offline formats such as Caliper Maptitude MAP files and Microsoft Excel workbooks, most of MPExporter’s options are relevant to someone wanting to move their maps into the geospatial web.
As well as KML, MPExporter can also create a HTML file (‘web page’) that uses either Google Maps or Bing Maps. Both of these options can be complete pages, or more usefully fragments that can be included into a page template.
Graphic designers and HTML5 users may also be interested in MPExporter’s SVG option. This creates a flat 2d SVG file from the MapPoint map, using one of a range of possible map projections.
MPExporter supports routes, shapes, and all user datasets except territories. Shaded area maps are usually converted to point datasets, unless MPExporter has the necessary shape definitions. These only ship with the Professional version, and at the time of writing this, MPExporter only has shape definitions for the US.
Prices for MPExporter start at US$75 and can be purchased from https://www.mapping-tools.com/mpexporter/buy_mpexporter.php .
