These methods have produced good results for some high-quality topographic maps
, but the results are not satisfactory for low-quality maps, mainly due to the following three problems : (1) color aliasing and false colors on scanned maps due to poor paper (such as paper turning yellow over time) or printing quality and the performance of the scanner (on a 96-dot-per-inch (DPI) resolution map, most contour lines are 2 to 4 pixels in width; thus, color deviation occupies a large portion in pixels of lines); (2) conglutination of adjacent lines to form thick lines in some areas of a scanned map where contour lines are densely distributed ; (3) a large number of contour lines gaps caused by intersecting and overlapping information on a topographic map
after color segmentation.

Statistical analysis determined the differences between the results obtained from the two data sources used to calculate the topographic factor, SRTM and topographic maps
The geospatial data will be used for topographic map
production to manage sustainable forestry projects and to support other local infrastructure needs, Intermap said.
Published in 2003 in Russian as an updated edition of a topographic and special maps manual for officers and for students at Russian and Soviet military educational institutions, this work represents a major contribution to the understanding and interpretation of Russian topographic maps
If the given purpose does not involve accurately identifying the position of the small tundra ponds, then the use of topographic maps
could be suitable, as the larger lakes were in good positional agreement with those mapped by the other methods.
The Ambios Xi-100 IFM uses white light interference to generate a three-dimensional topographic map
of the razor cut rubber surface (figure 1).
These topographic maps
are compiled from the most up-to-date Vicmap Digital data.

Aerial imagery and topographic maps
of the United States have also recently been added to the site.
