Evaluation is also continuing on the feasibility of map publishing for commercial purposes, thereby physically replacing the existing 1:25 000 hardcopy topographic
Zone information is listed in the lower left-hand corner of your topographic
maps on CD-ROM are a new product for the USGS," said James R.
While going through transition training to get settled in Afghanistan, 1st SFAB G-2 topographic
advisors learned of an unclassified hard drive, which contains an imagery data-set from the National Geospatial-Intelligence Agency.
Remotely sensed shuttle radar topographic
mission (SRTM) digital elevation model (DEM) data of 90 by 90 meter resolution is used for terrain analysis.
The aim of this study is to evaluate the accuracy in the remote sensing derived SRTM, ASTER and Topographic
DEMs and to evaluate the impact of these errors on the computed topographic
attributes, including aspect and slope.
Therefore, this paper presents a new method for extracting contour lines from average-quality scanned topographic
factor may be obtained from Digital Elevation Models (DEMs) by the application of USLE on the river basin scale.
Written by ophthalmologists and optometrists from around the world, the 13 chapters cover basic topographic
principles, including anatomy and optics and maps and scales; topographic
techniques such as three-dimensional systems, Placido disk-based topographic
systems, and combined topographers with whole eye aberrometers; and applications for topography in corneal diseases, contact lens fitting, pre-refractive surgery topographic
evaluation, planning topography-guided custom ablations and keratorefractive treatments, corneal biomechanics, and the integration of systems for calculating intraocular lenses.
True Surface Microscopy, a new technique developed by WITec GmbH, Ulna, Germany, combines confocal Raman microscopy for optical and chemical imaging with optical profilometry for topographic
large-area imaging in a single integrated system.
The geospatial data will be used for topographic
map production to manage sustainable forestry projects and to support other local infrastructure needs, Intermap said.
After the dissolution of the Soviet Union, a large number of Soviet topographic
maps found their way to various markets in the West.
