Fishmonger,

That's a nice iframe map.

As Fishmonger demonstrated, Gmap4 can run in an iframe. Thus you can include an interactive Gmap4 map in your trip reports. Fishmonger's iframe map opens with the Google Map Terrain view. You can switch the map to topographic by clicking (upper right) Terrain ==> MyTopo.

Gmap4 is not limited to running just in an iframe. This link will display Fishmonger's map in a new window and it will show the topographic view (since I added &t=t2):

If anyone is having trouble using Gmap4 then please post the URL command you are using just like I did above.
