It is possible to create client-side image maps by hand using a text editor, but doing so requires web designers to know how to code HTML as well as how to enumerate the coordinates of the areas they wish to place over the image. As a result, most image maps coded by hand are simple polygons. Because creating image maps in a text editor ...
The tutorials below follow the training of a hypothetical new map maker: the deeper you go, the more complexity and beauty you find. Demonstration of how an SVG map is built layer by layer: 1.Valley; 2.Plain; 3.Hill; 4.Rivers; 5.Troops; 6.Moves; 7.Text; 8.Locator map; 9.Legend. Topographic map with English information on it. The level 2 ...
Equirectangular projection of the world; the standard parallel is the equator (plate carrée projection). Equirectangular projection with Tissot's indicatrix of deformation and with the standard parallels lying on the equator True-colour satellite image of Earth in equirectangular projection Height map of planet Earth at 2km per pixel, including oceanic bathymetry information, normalized as 8 ...
PNG is a lossless, truecolor image format. It is good for all maps and particularly for maps with more than 256 colours. As a pixel-based image, it is more difficult than an SVG image to edit. Some uploaders prefer to work with SVG and then upload a PNG version. SVG is vector graphics format, which has three main advantages:
UV texturing is an alternative to projection mapping (e.g., using any pair of the model's X, Y, Z coordinates or any transformation of the position); it only maps into a texture space rather than into the geometric space of the object. The rendering computation uses the UV texture coordinates to determine how to paint the three-dimensional surface.
Map to coordinates: Move a marker on a Google Maps map (map or satellite view) and get Latitude, Longitude and Elevation for the location. User interface in German language.

Image rectification in GIS converts images to a standard map coordinate system. This is done by matching ground control points (GCP) in the mapping system to points in the image. These GCPs calculate necessary image transforms. [11] Primary difficulties in the process occur when the accuracy of the map points are not well known
The information can be entered by directly giving the coordinates or by selecting a location from a map using software tools. Some tools allow entry of tags such as city, postal code or a street address. Geocoding and reverse geocoding can be used to convert between locations and addresses.
