National Geographic Magazine - JOSM/Guide. Welcome to the JOSM guide.


This guide is split across several tabs (above), starting with an introduction aimed at new users. The text assumes some knowledge of OpenStreetMap concepts, and focusses entirely on using JOSM, not other tools. A - GIS Dictionary. OGC® Standards and Specifications. OGC(R) standards are technical documents that detail interfaces or encodings.

OGC® Standards and Specifications

Software developers use these documents to build open interfaces and encodings into their products and services. These standards are the main "products" of the Open Geospatial Consortium and have been developed by the membership to address specific interoperability challenges. Ideally, when OGC standards are implemented in products or online services by two different software engineers working independently, the resulting components plug and play, that is, they work together without further debugging.
