hi, and apologies for posting this as i'm new to both this site and to image processing.

i'm proposing adding a forum for programming techniques related to cartography to your site, as the "software discussion" forum is more for end users than developers.

admittedly i've only spent a week cobbling together the resources on image coding i can find online, which seem to be relatively disparate (1d, or audio dsp has a dedicated site at musicdsp.org) and have been finding bits and bobs, eg. the use of arctan2 for slope maps from terrain heightfields was gleaned from a thread in a delphi forum more than any educational source.

cheers!
