The "NavPix" name is used for both the software and the geo-referenced image that results from that software.

) meta data by the NavPix software. The NavPix, therefore, effectively provides a Georeference

To georeference something means to define its existence in physical space. That is, establishing its location in terms of map projections or coordinate systems. The term is used both when establishing the relation between raster or vector images and coordinates, and when determining the spatial...

 of the location where the image was taken, which is not necessarily the same georeference as the object being "NavPix-ed".

The NavPix image can then be used to define a destination or point of interest
Point of interest
A point of interest, or POI, is a specific point location that someone may find useful or interesting. An example is a point on the Earth representing the location of the Space Needle, or a point on Mars representing the location of the mountain, Olympus Mons.The term is widely used in...

Furthermore, as the geographical information is written to the meta data, the image itself can be shared between compatible devices or uploaded to Navman's NavPix Library which offers a wide range of NavPix images that have been taken by both Navman users and sourced from professional photo providers, including Lonely Planet

Unlike some geo-referencing applications, the NavPix Library writes the georeference values to the image itself via the Exif meta data.
