US Topo FAQs - 32 Found
US Topo is intended to serve map users who are not GIS specialists. The priority design objectives were to create a traditional topographic map, in a digital format that can be displayed on any normal office computer without specialized software, and printed at map scale without specialized software or expertise. We believe PDF is the only format in common use that satisfies these requirements. PDF is also the only commonly used format that can carry raster data, vector data, and formated text annotation.
The geospatial extensions add limited GIS functionality "for free" – no cost to end users, and no conflict with base PDF. Users who are not interested in geospatial functions can still use the product as a plain PDF. Further information about GeoPDF is available at this Wikipedia website, and in the US Topo and Historical Topographic Map Users Guide.
