ABSTRACT:
A mapping application relies on a modified affine transformation algorithm to provide near real-time navigation of imagery, track-up capability and integration of segment and picture data. The affine transformation is modified to map a “world space” comprised of a plurality of pixel maps onto a view port. The pixel data for the maps is preferably stored in vertical strips of memory to reduce the likelihood of cache misses. The mapping application is most useful for rendering pixel imagery on a platform with limited processing power, limited memory and small display sizes, e.g., “hand held devices” such as a GPS handset, or Pocket PC.
