Hi,
i have a question in OpenMap.
I wish to do a contour plot and my inputs will be like this, Assume
the X-Y as a rect surface length and breadth. Z is the depth. i.e
Graph the depth of a irregular shape.
( Array of X :: Array of Y :: Array of Z)
X Y Z
400 -200 -33
445 -100 -64
765 -567 -85
543 -345 -56
and the contour plot must be like
1. First of all draw a area based on points (use only X-Y) boundry.
You will get a polygon by joining (only) the boundry points.
2. Then draw the contour ( Z value) lines on this area.
3. Show shaded colors on the regions of the contour line.
This is nothing but a density graph + contour lines on a irregular area.
Is it possible to do using OpenMap. OR what do you feel. Based on
this feasibility only i can start my project.
Am i missing anthing here ? let me knw ur views. Thanks for ur time.
Cheers,
Leo
