Title: DIGITAL TERRAIN MODELS. CURRENT APPLICATIONS AND FUTURE CONSIDERATIONS
Accession Number: 00636503
Record Type: Component
Availability: American Association of State Highway and Transportation Officials (AASHTO) 444 North Capitol Street, NW Abstract: The New Brunswick Surveys and Mapping Committee and Energy, Mines and Resources Canada recently sponsored b project to investigate the current "state of the art" with respect to DTM capabilities, data collection techniques, machine resource requirements, and potential applications. Data was collected for 50 LRIS 1:10,000 map sheets (2 NTS coverage areas) in New Brunswick. A number of DTM software products were then used on different hardware platforms to measure resource consumption (CPU, disk storage) for generic DTM functions such as TIN creation, contour generation, terrain profiling, and slope/aspect map creation. Two specific applications - floodplain mapping and watershed delineation - were also investigated, using one of the DTM packages. Major conclusions and recommended areas for further research are given.
