This raster grid datalayer consists of global 30 arc-second resolution slope data derived from SRTM30 (Shuttle Radar Topography Mission) data, supplemented with GTOPO30 elevation data, ETOPO2 depth data, and other data sources. Slope (the incline or steepness of a surface) values in this datalayer are measured as degrees (0-90) from horizontal. The datalayer was produced by ISciences and published in 2003 as part of the TerraViva! SRTM30 global enhanced : elevation, slope and aspect, data set. SRTM30 data was collected February 11-22, 2000.From the ISciences Web site:"SRTM30 Enhanced Global Map is a global elevation and depth data set from ISciences at 30 arc-second resolution that includes an elevation map, slope angle map, slope aspect map, and source map. Each pixel represents an area ranging from one sixth of a square mile at 60 degrees to one third of a square mile at the equator. To get a view of your world as good as this you'd need a map 18 feet high and 36 feet wide! SRTM30 Enhanced Global Map was created by combining 27 SRTM30 elevation files, identifying and correcting anomalies, supplementing with elevation data from an alternate source for land areas not included in SRTM30, and adding depth data. The result -- a beautifully blended, high-quality, stunning global elevation and depth map suitable for display at scales to1:3,000,000."The ISciences enhanced global map data builds on SRTM data by offering a global composite, complete global coverage elevation dataset with rectified anomalies, computed slope and aspect data, and additional depth data.From SRTM Web site:"The objective of the SRTM project is to produce digital topographic data for 80% of the Earth's land surface (all land areas between 60° north and 56° south latitude), with data points located every 1-arc-second (approximately 30 meters) on a latitude/longitude grid. The absolute vertical accuracy of the elevation data will be 16 meters (at 90% confidence). This radar system will gather data that will result in the most accurate and complete topographic map of the Earth's surface that has ever been assembled.What can the data be used for?Space Shuttle Landing.These data can be tailored to meet the needs of the military, civil, and scientific user communities. But other uses of this data include improved water drainage modeling, more realistic flight simulators, better locations for cell phone towers, navigation safety, and even improved maps for backpackers.Just about any project that requires accurate knowledge of the shape and height of the land can benefit from this data. Some examples are flood control, soil conservation, reforestation, volcano monitoring, earthquake research, and glacier movement monitoring."None planned
