Supplemental_Information Procedures_Used This dataset was created by joining the thirty separate USGS 3 arc-second dem datasets that encompass the area of Missouri. The original datasets had various levels of resolution according to their present in this dataset. The join-lines can be considered the same as those of the 1:100,000 quadrangles of Missouri. Thus, the user can be advised to inspect their dem along these lines (if applicable). Although this dataset may be used for some hydrological analysis, the user should be aware that these data may not be applicable for smaller-streams. James D. Harlan December 16, 1997 Revisions n/a Reviews_Applied_to_Data Reviewed by James D. Harlan, December 16, 1997. Related_Spatial_and_Tabular_Data_Sets See county-level DEMs for finer resolution data. References_Cited United States Geological Survey. Defense Mapping Agency Notes This DEM could be referred to as 3 arc-second, 1:250,000, or 1degree x 1degree. It was originally created by the Defense Mapping Agency (DMA) and adapted by the USGS to fit as a DEM for their 250,000 (1deg x 1deg) quadrangles. Many sources were implemented in determining the elevation values for the dem mesh points with USGS and DMA 24,000 and 25,000 quadrangles being the most often cited. So, the scale of 250,000 is deceiving. The dem is only fitted to the 250,000 quad size or area. This DEM encompasses all of the state of Missouri as well as reaches 5 kilometers outside the state border to eliminate any cell interpolation problems along those lines.
