Re: [Geotools-devel] vector to raster to vector
A brief update for the list and Steve... I've proposed to merge the process module working branch into trunk. This will provide vector to raster conversion for users with the constraint that generated coverages have to fit into memory. I've begun building a disk-based tile cache for the jai-tools project. This will hold some number of tiles in memory with the remainder swapped to files. When this is working (fingers crossed) we can use it with both VectorToRasterProcess and RasterToVectorProcess. Simone: I think I can get the basic tile cache together but then I'll need help to add handling of concurrency.

I know at least one implementation of FileBasedTileCache, I need to clarify a bit the licensing issues. If you are interested I can purse that. Otherwise we can build our own. Simone. --- Ing.

Would that be the one in this project ? http://code.google.com/p/mobile-trail-explorer/ If so it's GPL.

Re: [Geotools-devel] vector to raster to vector
Hello folks, Somewhere back in this thread I mentioned contacting Steve Ansari about some nice vector to raster code that he posted on the user list last year. Steve is happy for this code to go into the library (Jody suggested it join the raster to vector code in the process module) so I pointed him to the contributor's agreement. I've just heard back from Steve and, as a US Govt employee, he feels that he can't proceed with the agreement. Apparently, his employer views the code as being in the public domain so it's fine for us to use it but not possible for him to sign over intellectual property (I'm cc-ing this to Steve and he can correct me if I've mangled that). Steve wondered if I could take ownership of the code to get around this, while he could still field queries about it and (I hope) benefit from any improvements that we come up with. Is that kosher ? Any other suggestions ? cheers Michael -- Register Now for Creativity and Technology (CaT), June 3rd, NYC. CaT is a gathering of tech-side developers brand creativity professionals.

Re: [Geotools-devel] vector to raster to vector
Yes, I guess was thinking of something similar to the DataUtilities class but I'm fine about doing it another way - whatever works best is best. Regarding the process module - yes, it is cumbersome for hands on use. I must admit that I've bypassed it when I've used the raster to vector function in my own code, and the trouble with that for the general community is that it's akin to secret knowledge. Are you thinking of something specific when you say make the code more useful where it is ?

Re: [Geotools-devel] vector to raster to vector
Yes I am ... I think we proposed a naming convention right from the get go. By convention we could make the process available using a static method to help with test cases and direct from Java use. // how about this? features = RasterToVector.process(raster, band, outsideValues, monitor); Nice :) Steve is happy for his vector to raster code to be included. Does he have to do the contributor agreement thing ? Michael PS. I put some spline generating code in the users guide page on creating curves a while ago. That might fit nicely in process too. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Re: [Geotools-devel] vector to raster to vector
Can we make the code more useful where it is? In the process module The process interface is useful for advertising functionality to dynamic applications; but not so friendly for hands on java hacking. For a utility class there are actually a couple of ways to do it; would you want to just add a static method to the code that implements the process? Or are you thinking something similar to the CRS and JTS and DataUtilities utility classes?
