Hi all,
I'm using OpenMap to present my GIS data and I'm using Geotools to read
in my shapefile data. And Geotools uses JTS to calculate the
intersection between two geometries. In a previous post I asked how to
write such filter. I have succeeded but now I want more. My current
problem is that I need to use a real distances (as angular distance in
decimal degrees) as a radius of my area and JTS is not aware of the real
distances.
In OpenMap the distance between two coordinates can be computed with the
following statement:
Length.Decimal_Degrees.fromRadians(latlonPoint1.distance(latlonPoint2));
This value is of a similar magnitude to the value I get when I use
geometry's that have the same coordinates as the above two points:
geometry1.distance(geometry2)
However, I would like it to be more similar :-) Is it possible in
Geotools or JTS to use a filter that uses the distances from geographic
coordinates?
Kind regards,
Jeroen
