USGS RASTER DATA FREE
These are modeled on the legacy 7.5-minute maps, but are mass-produced from GIS databases and published as digital documents.
USGS RASTER DATA SERIES
In 2009, a new USGS quadrangle topographic map series was defined. All the elevation samples in the file are translated to a three-dimensional (3D) FME raster. The last printed USGS topographic maps were published in 2006. USGS DEM files are raster files containing elevation data. Map revision continued, though in decreasing quantities, through the 1990s. The 7.5-minute series was declared complete in 1992, and at that time was the only uniform map series that covered the United States in considerable detail. Similar maps at varying scales were produced during the same time period for Alaska, Hawaii, and US Territories.
From approximately 1947 to 1992, more than 55,000 7.5-minute maps were made to cover the 48 conterminous states. The best known USGS maps are the 1:24,000-scale topographic maps, also known as 7.5-minute quadrangles. The USGS was entrusted with the responsibility for mapping the country in 1879 and has been the primary civilian mapping agency of the United States ever since. Am I crazy to contemplate trying to write such a command? (This last question is mostly rhetorical.Example topographic map. If there are no such commands, is there interest (other than my own) in having such a command?ģ. Am I correct that there is no user-written Stata command(s) that can merge raster and shapefile data into a Stata dataset?Ģ. Existing (and very helpful!) user-written Stata programs either work with raster data (-ras2dta-) or shapefiles (-shp2dta-), but as far as I can tell there is no user-written Stata program that brings data from these two different formats together.ġ. Note that most of the high K values are in the southeast area.
Figure 6 shows the raster created for the K factor. Soil Survey Shapefile > Soils high in clays tend to have low K values (0.05-0.15) because they are more resistant to detachment.
USGS RASTER DATA SOFTWARE
I believe that one can do this in ArcGIS and other software packages, but I was curious about whether it is possible to do this using Stata. As an agency heavily involved with spatial and mapping information, the CGS is moving more and more to dynamic GIS data presentation for ease-of-use and for. type is converted into raster data of K factor by the feature to raster function of GIS. So I think I would need to merge the USGS raster data on elevation (National Elevation Dataset - ) to the Census Bureau's Tiger shapefiles. The Census Bureau does not provide such data and refer one to the US Geological Survey, but as far as I can tell, the USGS does not provide data matched by Census Block. I would like to obtain elevation data by US Census Block. raster image of contaminationpotential scores across the State.
