NPScape United States Department of the Interior National Park Service NPScape is a landscape dynamics monitoring project that provides landscape-level data, tools, and evaluations for ...
The viewer was made seamless by incorporating GDAL. In addition to matching the Topozone URL's, the website offers free download of GeoTIFFs, which Topozone had only offered for a premium. TopoQuest started adding Canadian 1:50K scale topographic maps in July 2008, and USGS 1:100K and 1:250K scale topographic maps in March 2009.
Geoforge provides open source software. It leads in a platform [13] that manages geosciences data and uses WorldWind features to provide a display of geo-localised geosciences objects. Dapple [14] is a fork of the NASA WorldWind project, it is an Open Source project created by developers at Geosoft.
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
OpenStreetMap (abbreviated OSM) is a free, open map database updated and maintained by a community of volunteers via open collaboration. [4] Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources.
In 1995 the USGS was in need of a Windows viewer for their data products, so they developed the dlgv32 application for viewing their DLG (Digital Line Graph) vector data products. Between 1995 and 1998 the dlgv32 application was expanded to include support for viewing other USGS data products, including DRG (topographic maps) and DEM ( digital ...
OS MasterMap's data is in GML format. It is usually delivered as files compressed with gzip (providing them an extension ".gz"). [7]Recently, Ordnance Survey has been trialing delivery of OS MasterMap data using WFS and WMS, in accordance with the Open Geospatial Consortium.
The Centre for Topographic Information produces topographic maps of Canada at scales of 1:50,000 and 1:250,000. The full map catalogue is known as the National Topographic System (NTS). [ 16 ] A government proposal to discontinue publishing of all hardcopy or paper topographic maps in favor of digital-only mapping data was shelved in 2005 after ...
