I am trying to create a personalised Google Maps style map of a certain portion of Mars! that will show three specific locations. Namely (a) Gale Crater (b) Hebrus Valles and (c) Valles Marineris.
At https://www.google.co.in/mars/ I can locate all three quite easily using the search feature but at any point in time I can show ONLY one of these location. What I want to do is to show ALL three simultaenously on the same map but cannot do so.
I have also tried going to https://www.google.com/maps/space/mars but could not find the search feature to show these three locations.
If I can see all three locations with the balloon markers simultaenously, I can take a screen-shot and create the map I am looking for.
Would be grateful if someone could help me create this map, or give me some pointers on how I could do this?
