TGoogleMapType = (MT_NORMAL=1,MT_SATELLITE,MT_HYBRID,MT_PHYSICAL,MT_SATELLITE_3D) WGS84_MULT_FACT = 100000 // multiply lat/lon values by this value in order to fit them into integers Good luck, and let me know if you've created something useful with it. It's used to simplify a polygon when you run out of resources. The unit DouglasPeuckers is not really needed.

It doesn't intend to wrap the full API it's just to make life easier when dealing with Google maps. MyPolygon := TGPolygon.Create(MyPointArray) It lets you create polygons using fast Delphi arrays and then plot that in GMaps GoogleMaps1.RemoveOverlayByIndex(3) // delete overlay 3 Keep a list of overlays, and manage it via Delphi structures: // hide overlay 2 Switch to the embedded version of Google Earth, for fast and smooth 3d action: GoogleMaps1.MapType := MT_SATELLITE_3D Load a KML or KMZ file: GeoXML := TGGeoXML.Create('') Here are a few examples of how you can use it:Д¬enter the map to some shithole in the Netherlands, with nicely rounded coordinates: GoogleMaps1.SetCenter(52,5,True) On this screenshot I've switched to the Google Earth view: I've put a demo executable and sourcecode online here: It expands on the idea that was posed here: It can use some work, but it has done some nice jobs for me already. The HTML file is embedded into the exe as a resource for easy deployment. It's a component that contains a TWebBrowser that loads a local html file that contains some javascript helper functions and sets up a basic Google maps page. I've wrapped the Google Maps API some time ago. I would like to use a Mozilla component but it seems to be only for C++. Is there other options to use Googlemaps? I don't know other html-components for Delphi than TWebBrowser due to bad performance and memorymanagement. I found this clumsy, but I see no other way. As the API-key is bound to a domain or a local-file I guess I have to save a javascriptfile with coordinates and then load it in TWebBrowser for every call to the map. From Javascript I can call GUnload to eliminate the memleaks according Googlemap documentation. I also found that it works to load a local html-file. Right now I have registed a API-key for my own site just for test.

Yes I know Googlemaps license policy and we are prepared to pay Google the price when the solution is used in reality. Besides that there seems to big memleaks in IE.ДЄnother option is to use TWebBrowser component instead and load a Googlemap html-file to show the same thing. It works, but it can be slow if the the amount of coordinates is higher than say 10. Then Google map display the best direction to drive through the coordinates. The current solution (that is really bad) works by starting Internet Explorer from ShellExecute, load some coordinates in the Googlemap URL. And we feel that Googlemap seems to be the best value for the money compared to some map components. Now we have started to look at mapsupport. I'm a member in a team that maintains a quite big inhouse Delphi application.
