Hi,

I was just looking for the same and came across this. Not sure what it
can do but it is worth a look https://code.google.com/p/mapviewer/

hi!
there is an old post with a sample application to display not only
google maps but also maps from microsoft ...
the sample code is a liittle bit slow but can serve as a starting
point how to use the apis ...


good luck !

I can confirm that this works. The sample application may be a bit
slow but I've tested it and I quite like it.

Strange. Mine still works. I just tested it. You need to be able to
compile synapse and then compile and add the MapViewer package. Mind
you, your Lazarus version is a bit dated. Maybe that is why it is not
working (I'm not sure, just a suggestion).

Can you compile synapse?

sysnapse 4.0?

----------------------------------------------------------------------

On the 1.6.2 i can compile sysnapse 40.1, but cannot compile
mapviewer. the same error... cannot find  httpsend.

httpsend is in httpsend.pas (part of synapse) You will have to add
httpsend to your uses clause.

i've solved at the end.

add the missing file to the project and use recompile all required.
