Dear All, I apologize if this has been discussed before.
To put it simply, ihave: 1. a set of, say JPEG, images. 2. a CSV file describing the lat-lon coordinate box for each of the images (each record also include the coordinate system code, scale name, image size in pixel, etc.), something like: image_name, cs, width, height, x1, y1, x2, y2, x3, y3, x4, y4 image1.jpg, 4801, 2000, 2000, 135.123, 39.123, ... image2.jpg, 4801, 2000, 2000, 135.123, 39.123, ... .... 3. the boundary of the whole area covered. My objective is: to have a simple function to get an image given any box within the boundary (3) above with a specific CRS. Something like: Image getImage(float x1, float y1, float x2, float y2, CoordinateReferenceSystem crs); This function supposed to get some portion of one file, some from another, etc., should the box requested covers the area of more than 1 image. I was thinking of using GridCoverage, and I tried to study GridCoverage2D, FileSystemGridCoverageExchange, .. and other seemingly related classes, but I am currently stuck on how to knit these things together.. So, basically, my question is: 1. Is it even possible to use geotools to do what I wanted. 2. If it is possible, I would appreciate very much if anybody could give me as much as a hint on which classes/methods I should go to. 3. If it is not possible, is there any other kind of data/file/info, etc. that is required to achive this objective. Thanks a lot in advance, Purbo ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
