[Geotools-gt2-users] Raster interpolation that ignores NO_DATA?
Hi, I load dem (srtm) data that contains NO_DATA cells. I want to calculate z-values for Coordinates (using bilinear interpolation). My problem is now that some cells have NO_DATA (-32767) values. Is there an interpolation method that can ignore NO_DATA? I know there is no perfect solution and in theory all cells could be NO_DATA. A simple approach that uses only the valid neighbors coul work in my case. Any ideas how to achieve that? Here is the code I currently use: GeoTiffReader reader = new GeoTiffReader(f); GridCoverage2D c = reader.read(null); GridCoverage2D coverage = Interpolator2D.create(c, Interpolation.getInstance(Interpolation.INTERP_BILINEAR)); Point2D.Double p = new Point2D.Double(10.4, 52.1); double[] r = new double[1]; coverage.evaluate(p, r); Cheers, Jan -- Dive into the World of Parallel Programming.

Re: [Geotools-gt2-users] Problem iterating over a graph
Nicolas Malleson wrote: You got me thinking though, is it possible that there is some manipulation of the underlying graph going on in the background? It looks like the sub-graphs might be changing the underlying graph somehow (which would explain why the rate of success drops as more and more are created), but I can't see how they would be doing this. To get the subgraph I use the visited nodes and edges in the BasicGraph constructor, but again I don't think that this should do anything to the underlying graph. You should read the source code of the involved GT components in order to understand how the traversal works. For me, it wasn't intiutive at the beginning but the author clearly had a plan.

[Geotools-gt2-users] Finding subgraphs in graph
Hi, I have a graph (org.geotools.graph.structure.basic.BasicGraph) and I want to find alls its subgraphs (that is, all componenents that are not connected with each other). I think there is no such algorithm already implemented in GT and I only came up with a n^2 solution, yet. I think n log(n) should be possible. Do you know if there is an Algorithm in n log(n) which is not recursive? My graph has a max depth of ~ 200Mio so I *think* recursion matters (I might be wrong) and a simple depth-first traversal is not efficient.

I understand the math, and can do that if needed, but I find it hard to believe that this type of functionality has not already been written. You explicitly mention WGS84, so one question: Do we speak about a circle of a few tens of meters or about really large scales? In the first case, I recommend the GeodeticCalculator.

Hi,
Hi Jan, thanks for responsing.
I have installed Maven and now I understand how to get packages :)
But still I don´t know what packages/dependencies/repositories do I need
in
order to compile Geotiff examples. (GeotiffReader, GeoTiffFormat... )
Please always reply to the list so other can benefit from your question.
I use:
dependency
groupIdorg.geotools/groupId
artifactIdgt-geotiff/artifactId
version${gt.version}/version
/dependency
the version can be 2.6.4 for example.
The geotools repository is:
repository
idgeotools/id
urlhttp://download.osgeo.org/webdav/geotools//url
snapshots
enabledfalse/enabled
/snapshots
/repository
And you may need the JAI libs if you play with geotiff.
repository
iddev.java.net/id
urlhttp://download.java.net/maven/2//url
releases

Notice my other thread: I have all classes but didn't succeed with reading

[Geotools-gt2-users] geometric operations on WGS84 data
I have several data (JTS) in different coordinate reference systems, let's assume wgs84. I want to perform some simple operations on them, like buffer or polyline simplification. I didn't find any buffer or simplification algorithms in geotools with let me specify parameters in meters. Instead all algorithm just assume a Cartesian coordinates. So I either need suitable algorithms for geodetic reference systems or an automatic back-and-forward transformation into an Cartesian coordinate system on an abstract best-fit base. (I.e. convert data to the best matching Gauss Krueger stripe) Is this a good approach? Or do you have a better solution?

[Geotools-gt2-users] JTS, WGS84 and Coordinate
Hi, In which order expects JTS Coordinate the values? I thought, Coordinate(lon, lat) would be the correct format. For example I have some OpenStreetMap data in my database: SRID=4326;POINT(12.1589415 47.5672387) which is lon/lat somewhere in Austria. When loading such data into JTS Point (using the postgresql_jts JDBC driver) I get an object like; (com.vividsolutions.jts.geom.Point) POINT (12.1589415 47.5672387) Up to this point I was absolutely convinced that JTS stores WGS84 coordinates as lon/lat. But, When I used the JTS#transform() I noticed the following: JTS.transform(factory_wgs84.createPoint(new Coordinate(100,30), sometransformation) throws the exception: Latitude 100°00.0 is too close to a pole. Why does JTS#transform() interpret the first axis as latitude and the second as longitude? And which behaviour is correct? And more important, how/where can I fix it? How does geotools handle this in general?
