Hi all, I'm in need of some help.
I'd like to try to 'fill' the coastline data derived from e.g. OUTLUSAM using the mcidas BaseMapAdapter. Using the Rivers.java
approach, I can get the coastline drawn as lines, but not as filled polygons. I should point out that I am not entirely certain
that the data in OUTLUSAM is actually all closed polygons.
I did see on the list how DelaunayCustom.Fill might be useful. However, I got
an exception
visad.VisADException: path self intersects
at visad.DelaunayCustom.fillCheck(DelaunayCustom.java:499)
at visad.DelaunayCustom.fillCheck(DelaunayCustom.java:451)
which may or may not have been specific to my data.
My bigger concern is that i am using a display side coordinate system and Map Projections from ucar.unidata.geoloc, much like
the IDV does. It seems to me that I cannot do the fill in lat/lon, I would need to fill in x,y, or am I being very stupid?
I did also consider making a FlatField from the data, e.g. lat x lon -> VALUE, with all values 0, and then using IsoContour fill
the fill option on and setting the contour levels to include 0. Not sure about this.
Any help gratefully appreciated.
Stuart
