[mkgmap-dev] Show direction in contours (patch)

From Petteri Aimonen jpa at mkgmap.mail.kapsi.fi on Sun Sep 19 21:08:16 BST 2010


I had an idea to show the direction of the slope in elevation data 
contours. To implement this, I made a small modification in DEM.java so 
that contours are always created in the same direction:

Then I just used the bitmap mode in the TYP editor to make small arrows 
that point downwards:

This patch could be added to the main branch, and the TYP file then 
specifies whether to use arrows or not. Currently the contours start in 
random direction depending on the shape of the area.

PS: Thanks for the great program!
