Hello, I am completely new to GIS and have a project that requires some GIS functionality and I have spent the last week (in vain) trying to do it from first principles, learn how I might use geotools2 from the geotools wiki and the javadocs, and I have to say I am more confused than when I started, though I have learnt of the existence of a lot of concepts, I don't quite grasp how they might be used to help me solve the problem at hand.
My problem is as follows: I have: + an map image in PNG format + the latitude and longitude of the CENTER of the above map + the projection of the above map (plate carree) + the datum used for the above map (NAD83) I need: + the latitude and longitude of the top left and bottom right corners of the map + the latitude and longitude of the point that is <width-of-map-image> pixels to the right of the center of map + the latitude and longitude of the point that is <height-of-map-image> pixels to the bottom of the center of the map Unfortunately, after all the reading and searching, I am completely lost and really do not even know where to start looking. A small snippet of Geotools2 code that does something like the above would be incredibly useful in pointing me towards the right modules of the geotools codebase where I can dig deeper. I know that has probably something to do with the referencing module, but I have NO idea what the code needs to look like to get started. Any help at all would be GREATLY appreciated. Thanks so much in advance for your patience with a newbie query. -- View this message in context: http://www.nabble.com/Newbie-question---completely-lost-tf4741832.html#a13559790 Sent from the geotools-gt2-users mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
