For the maps discussed here, the manual constructions involved preceded the mathematical development of map projections. After that, the gazetteer points were most likely plotted using the grid of meridians and parallels locally to calculate the locations.

Figures 5 and 6 are the negative-z and positive-z (respectively) paraboloid texture map projections of the environment depicted in the cubic texture map in Fig.
In order to satisfy the demands of cartography from an SLR imagery, the space map projection problem for SLR has been examined.
One of the basic requirements for processing data on building site network is that reductions in the ellipsoid and map projection should be avoided, because design engineers customarily work with actual ground distances.
A successful Geographic Information System (GIS) depends largely on using map projections correctly, with one person's skills in managing and converting projections frequently dictating the overall value of a particular database.
The CCCM site uses the MapGuide Dynamic Authoring Toolkit (DAT) to generate some additional advanced features such as dynamic map projections to convert the current map view into the local coordinate system familiar to the users as well allowing the map to only show layers that are pertinent to the region currently in view.
Another common and useful tool available to GIS users through photogramme try is an image called a "digital orthophoto." A digital orthophoto is a digitized aerial photograph that has been geometrically corrected to its true map projection. The orthorectification process ties each pixel in a digital image to its true earth location, making measurement from one pixel to another accurate.
Based on the originating sources and dates of the maps, they believed that the map data was current and accurate; however, in order to make use of this data, it was necessary to digitize and re-project the data from a Soviet map projection into a more user-friendly system using world geographic coordinates.
Other qualities include familiarity with data types, such as point data and polygons, and knowledge of geographic fundamentals, such as map projection. and scale.
Technical users can request any common map projection to ensure compatibility with existing geospatial data layers.
Users may further limit their searches by map projection or scale.
