Abstract
 The Use of ArcGIS 9 to Generate Large Elevation Products Track: Cartography and Map Production Author(s): Xiaopeng Li, Steve Dowding, Trina Kuuskivi, Henry Gansen This paper will describe how ArcGIS tools were used for generating countrywide and U.S. statewide DEM datasets derived from the Shuttle Radar Topography Mission (SRTM) data. ArcGIS tools were selected because of their superior end-to-end functionalities and capabilities for producing large raster DEMs. For example, ArcView Software's World Political Boundary shapefiles were used to determine the extent of each country and U.S. state; ArcView Spatial Analyst Software's Mosaic function was used to merge the data. The final products are consistent and homogeneous DEM datasets in GRID format together with a shaded-relief rendition of each DEM. In this paper, the SRTM data, methodology, tools, processes and procedures of the project will be described in detail. In addition, the paper will address how ArcGIS successfully dealt with the issues inherent when working with the SRTM datasets and the quality control processes needed. Conclusions and potential applications of the products will be provided at the end of the paper. Xiaopeng Li Intermap Technologies Corp.
