All Terrain Digital Elevation Products -- SRTM Native Resolution

http://www.allterraindigital.com/srtmnat.html

Oil and Gas Exploration. At 3-second resolution (1-second in the U.S.), SRTM. Grids offer superb regional to continental coverage. SRTM tiles are 1x1 degree, with 1200 cells per degree (3600/degree in the U.S.), and data volumes for the digital grids are roughly 350kb/1000sqkm at mid-latitudes. With seamless, consistent, nearly global coverage, and no data gaps due to clouds, these data are well-suited for large areas of interest.

All Terrain Digital Elevation Products -- GIS Raster Grids

http://www.allterraindigital.com/grid.html

Oil and Gas Exploration. Our standard output format for elevation and surface data is a grid for use in a Geographic Information System. The grid contains elevation or surface measurement values. The data can be referenced to any coordinate system, datum, and/or projection of your choosing. The format can be any of the widely-supported binary or ASCII GIS raster formats, such as BIL, DEM, IMG, or ASCII GRID.

All Terrain Digital Elevation Products -- Printable

http://www.allterraindigital.com/printable.html

Oil and Gas Exploration. In addition to - or instead of - digital elevation data files, we can provide printable maps as PDF files. These maps can be simple color shaded-relief or contour maps, or can contain other data layers such as roads, cities, rivers, or any other available data. Maps can be made to any projection. To match other maps you may have, and they can be made to any scale (may require more than one map sheet). Roll over options to see formats or click for details.

All Terrain Digital Elevation Products -- ASTER 30m

http://www.allterraindigital.com/aster.html

Oil and Gas Exploration. On board EOS Terra has been collecting stereo 15 meter imagery since 1999. We generate low-cost, high-quality 30 meter elevation grids from the extensive global collection of imagery. In most areas, multiple stereo pairs are available, allowing creation of low-noise 15 meter elevation grids. In addition, ASTER provides 14 channels from visible to thermal wavelengths for ground cover mapping. Roll over options to compare resolutions or click for details.

All Terrain Digital Elevation Products -- Aspect

http://www.allterraindigital.com/aspect.html

Oil and Gas Exploration. Aspect refers to the compass direction that a surface faces; put another way, it is the compass direction in which water flows down a surface. Aspect is an important factor in ecology, where vegetation and animal communities vary with aspect. It is also important in weather-sensitive applications, such as fire-fighting, and alternative energy projects such as wind and solar.

All Terrain Digital Elevation Products -- Drainage Network

http://www.allterraindigital.com/drainage.html

Oil and Gas Exploration. The earth's surface is in a continous interaction with water, controlling the flow of runoff, streams, and rivers while at the same being re-shaped by those flows. Elevation grids can be used to extract the flow patterns and create drainage networks and flood models for planning, hazard mitigation, resource management, hydro power, and more.

All Terrain Digital Elevation Products -- Insolation

http://www.allterraindigital.com/insolation.html

Oil and Gas Exploration. Insolation - total solar energy on a given surface in a given period - is a critical factor in the siting and design of houses, buildings, and solar power systems, and in climate and snowmelt models. Insolation varies with time and location, especially with local terrain orientation. We provide computed insolation values for any time interval and other parameters you specify.

All Terrain Digital Elevation Products -- Contour Lines

http://www.allterraindigital.com/contour.html

Oil and Gas Exploration. Elevation grids can be converted to GIS vector format as contour lines at an interval of your choosing. An appropriate contour interval depends on the grid resolution, topographic relief, and anticipated map or display scale at the data will be plotted. The PRISM-based 5m grids can reasonably support contour intervals as low as 3 meters. Contours can be output in common vector formats such as SHP, TAB, or KML.
