Image City Maps (ICMs), support close-in navigation, planning, and urban area operations. ICMs are designed as a replacement for hardcopy city graphics. Distribution is in both paper and digital versions. A virtually identical product, called Photomap, was produced from 1999-2002, however, Photomap now provides U.S. city coverage using only commercial source materials.
The ICMs consists of downgraded National Technical Means (NTM) or commercial, one meter resolution aerial imagery with important facilities such as government buildings, schools and power stations identified by numbered vector overlay. The key for these numbered vectors is located in the margin. Vector overlay of elevation contours at intervals consistent with local relief.
