For example, the orthophotomap information is essential for the updating of the topographic
database, and the topographic
elevation information is critical for the generation of the orthophotomap.
sheet of the study area at a scale of 1:50000 is acquired, which is developed by the Survey of Pakistan in 1998-99.
Automatic identification of contour lines on scanned topographic
maps has been a hot issue, and a great number of related literatures have been published recently.
When built by remote sensing techniques, such as Interferometric Synthetic Aperture Radar (InSAR), DEMs gain importance because they are obtained by a rapid and accurate topographic
data collection technique (RABUS et al.
The manual is organized in four sections: general information on the Earth's atmosphere, weather and climate; basic data on topographic
and special maps; description of terrain types and their properties with an assessment of battleground pros and cons; and procedures for maintaining the maps.
According to Mike Abrams, ASTER science team leader at NASA's Jet Propulsion Laboratory in Pasadena, California, the new topographic
information will be of value throughout the Earth sciences and has many practical applications.
Land-management practices geared toward cattle production should thus be influenced by topographic
variation, thus, affecting the structure and quality of grassland bird habitat within the Flint Hills.
