Online mapping apps like Google Maps and Bing can also read and display KML files, which means that readers can choose to see the route highlighted on a map with towns and cities labeled that they can zoom in on and pan. The utility of generating a KML file is a no-brainer.
Map to coordinates: Move a marker on a Google Maps map (map or satellite view) and get Latitude, Longitude for the location. User interface in English language. Mapcoordinates: 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.
Keyhole Markup Language (KML) is an XML notation for expressing geographic annotation and visualization within two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer.
Either click on the KML file link, or right-click on the link and select "Download file as..." (or a similar option) A file index.php will be presented for download (containing the KML content) Rename the file so that it ends in .kml (index.kml for example) Download the file.

The Vector data model uses coordinate geometry to represent each shape as one of several geometric primitives, most commonly points (a single coordinate of zero dimension), lines (a one-dimensional ordered list of coordinates connected by straight lines), and polygons (a self-closing boundary line enclosing a two-dimensional region).
The QRA locator system was limited to describing European coordinates, and by the mid-1970s there was growing need for a global locator system. [ 3 ] By the time of their April 1980 meeting, in Maidenhead , England, the VHF Working Group had received twenty different proposals to replace the QRA locator grid.
A WKT format is defined to describe the operation methods and parameters used to convert or transform coordinates between two different coordinate reference systems. The WKT 1 and WKT 2 formats are incompatible regarding coordinate operations, because of differences in the modelling. [13]
