CONSIDERATION ABOUT THE COSTS OF ORTHOPHOTOPLANS IN ROMANIA PUBLISHEDLaurentiu Pana, Mihaela Spilca
Today, many uses for geospatial mapping products require current planimetric feature data. Analysis and design from geospatial data sets generally require a known positional accuracy of features. The collection and updating of planimetric features in a data set can be costly. Many end users are also not accustomed to viewing and analyzing vector-based mapping data sets. They prefer to view planimetric features as a photo image. An orthophoto map would show the arch as an easily identifiable unique image feature. The cost to collect and update planimetric features can be significant. Costs can sometimes be minimized by the production of a photo-based digital map set that is spatially accurate throughout. Many GIS data sets make use of photo-based image data for these purposes. The Internet offers orthophotograph tutorials which may aid managers interested in the basic study of the subject.
