Geospatial data support with GDAL
OpenOrienteering Mapper uses the GDAL library for supporting a broad range of geospatial raster data, such as GeoTIFF or JPEG2000 files, vector data, such as Shape, OSM, or DXF files, and hybrid formats such as PDF. GDAL’s vector data support used to be known as OGR, so you will sometimes find this name, too.
Geospatial raster data and vector data can be used as templates. However, currently only graphical templates can be displayed; Mapper does not yet process raw raster data, such as altitudes, which first need to be rendered in other software. It also possible to open vector data files as maps and to import vector data into map files.
In addition, the File menu offers the option to export a map in selected geospatial vector data formats. The actual GDAL driver is selected by the extension (e.g. “.dxf”) given to the filename.
When using GDAL formats as templates, some filename extensions may be supported by multiple providers (plain image, GDAL raster data, GDAL vector data).
Please note that some of the raster formats listed below are not used for images but for actual geospatial metrics meant for algorithmic processing.
The following list is valid for the official Android, macOS and Windows releases as of v0.9.4. Linux packages are likely to support a slightly different set of formats, depending on the configuration of the distribution’s GDAL package.
