About PTM files

The .PTM extension primarily identifies the MapPoint Map File, a proprietary format generated by the now-discontinued Microsoft MapPoint software. These files contain geospatial data, route planning information, and embedded business analytics.

Because Microsoft ceased development of MapPoint in 2014, .PTM files effectively trap valuable geographic data in an obsolete ecosystem; modern tools like Microsoft Excel or Google Maps cannot natively import them. To access this legacy data without maintaining a Windows 7 virtual machine, users should convert these maps to PDF for archival viewing or static raster formats like JPG and PNG for easy sharing.

A secondary, technically distinct use of the extension is the Polynomial Texture Map, a specialized raster image format used in Reflectance Transformation Imaging (RTI) developed by HP Labs and often used by Cultural Heritage Imaging. Unlike standard images, these files store surface texture and lighting data, allowing users to interactively change the lighting direction. Since web browsers and standard editors like Adobe Photoshop do not support this scientific format, users must often convert them to standard TIFF or JPG files (flattening the lighting effects) to publish or print the visual data.
