Hello!
my code works now, if I include gis jar in the classpath in the prompt
while compiling the code using javac and even in the HADOOP_CLASSPATH
variable in the hadoop-env.sh file.
But, since my code required only one jar, it worked. Now, if I got to
bundle all the jars and then include it in
Hi Michael,
Thank you for your reply.
I also found those SLD examples, and this is the way I'm using them:
HeatmapProcess process = new HeatmapProcess();
GridCoverage2D cov = process.execute(fc, // data
20, //radius
null, // weightAttr
Trying to find the right way to test line overlap when the points are not
common. I have a set of lines containing points collected from a GPS
receiver. I need to find which of those lines travel a particular stretch
of the route. The functions geometryA.contains(geometryB)
and
Hello,
The code to retrieve the Style from the SLD file should look more like this...
/**
* Create a Style object from a definition in a SLD document
*/
private Style createFromSLD(File sld) {
try {
SLDParser stylereader = new SLDParser(styleFactory,
Hello Steve,
If you can define a tolerance within which geometries should be
treated as coincident you could use Geometry.buffer and then test for
intersection etc.

Is the tolerance that you speak of referring only to Geometry.buffer()?
I've tried setting Geometry.buffer but it had no effect on my line string
comparison.
geometryA.buffer(100);
geometryA.contains(geometryB) -- false, except when geometryB is an exact
subset of points from geometryA.

Calling geomA.buffer(dist) does not modify geomA, it returns a new
buffered geometry...
double dist = ...
Geometry geomB =
