I would strongly suggest trying this its very simple, no need to make perfect maps just get the right topography for the area if you are into making scenarios.
Takes time to fill in hexes correctly but can just do a quick approximation based on google maps satellite & or the map the app uses.
Very simple to do once you have done it once its second nature.
Remember you can turn the map to suit your needs before generating.
Wont cover using this app as covered already but here is a few simple steps to select some suitable terrain.
1)Use a latitude longitude website such as
http://latitudelongitude.org/pl/plock/
2)Do one of the following
Select a country then city if that's what you want or select tools - address to latitude longitude.
3)Second option either type in the address or scroll around using google maps satellite view is available if desired & its fast.
4) Once you have an area of interest press the marker to centre button.
5) Cut & paste Lat & Long into this app in another tab & generate the map.
6) I suggest using "save as" so you can move areas slightly in either tab & save another one.
7) Once you have done a few load up the map editor & see what you have.
8) Remember you can crop the map to suit your needs once you have saved it.
Attached are 2 maps showing different topography.
One is a local hill in New Zealand, not a quick climb which dominates the area & yes its well represented with 2 peaks.
Second just a random grab of Afghanistan hills as they rise from the flatter terrain in the bottom left corner.
Different countries / areas produce different types of terrain as they should so let the app help you out or inspire you.
