How can GeoTIFF formatted SRTM data be used in 3-D modeling?
• For 3-D fly-throughs using elevation data and surface imagery, many software can take GeoTIFF directly, such as ERDAS Imagine. • For Hydrological/Civil Engineering modeling, many applications such as Mike11, take solely USGS DEM format. In these instances, it is recommended that GeoTIFF files be converted to DEM format, which much spatial software can accomplish. • Some 3-D GIS applications accept GeoTIFF directly while others may require conversion to DEM or ArcGRID formats.
