I like this proposal.  I would dearly like to be able to "offset and
enlarge".

A 'point picture' entity would open up a way to achieve this, along the
lines of my example below.

 

Andrew, below is an example of how I have created two maps in the same
thconfig file and then inserted one into the other.

I think it would work well for creating locality plans, ie cave @1:1000 and
locality at 1:10,000, blacked out and with surface image enabled, but as
Martin pointed out, it is too clumsy for local enlargements in a dataset
where active extension of the cave survey is ongoing.

 

#Make elevation first so that it's pdf can be added to the plan


export map   -projection [elevation 270 deg] \

  -layout LayoutMapBulmer_System             \

  -layout LayoutMapBulmer_SystemElev       \    

  -output ./Output/MapBeautifulBulmerSystem_Elev.pdf  

 

#then make the plan with the elevation inserted  

 export map -projection plan          \

  -layout LayoutMapBulmer_System     \

  -layout LayoutMapBulmer_SystemPlan \

  -output ./Output/MapBeautifulBulmerSystem_Plan.pdf

 

The file LayoutMapBulmer_SystemPlan.thc contains the line;

 

  map-image 0.8 103 sw "./Output/MapBeautifulBulmerSystem_Elev.pdf" #0.8
needed to align plan & elev vertically

 

to insert the elevation into the map.

 

Keep up the good work

Bruce
