A
very common procedure in Surfer is to overlay maps. For instance, you may
want a base map outlining your area overlaid onto a contour map that displays
elevation of the area.
In
previous versions of Surfer you would create the individual maps separately and
use the Map | Overlay Maps command
to overlay them into one map frame. In Surfer 9, this command was removed and
instead you
can add a new map layer to an existing map, or you can overlay two separate
maps using the Object Manager. The
Map | Overlay Maps command has been
reinstated in Surfer 10.
If
you are using Surfer 9 you can:
Add a New Map Layer to an Existing Map
If
you have one map already created and want to overlay another map, you can add
the new map layer to the existing map:
- Click
on any part of an existing map to select it (i.e. one of the map layers, one of
the axes, or the map frame itself).
- Choose
Map | Add and select the new map type
you wish to add, such as Base Layer
to add a new base map layer.
- Select
the base map file to load and click Open.
The new base map layer is automatically added to the existing map.
Overlay Two Existing Maps
If
you have already created both of these maps separately, it is very easy to
overlay them:
- In
the Object Manager, select the map
layer in one of the map frames (i.e. Contours).
- Hold
down the mouse and drag that map layer from its map frame into the other map
frame (i.e. next to the Base layer).
- Release
the mouse button. That will overlay the two maps together in one map.
- You
can delete the left over empty map frame by right clicking over Map in the Object Manager and going to Delete.
Please see the video demonstration attached.
