Paper Abstract

Recent activity in synthetic reference scene generation from geographic data bases has lead to new and expanding production responsibilities for the mapping community. It has also spawned a new and growing population of geographic data base users. Optimum utilization of this data requires an understanding of the natural and cultural patterns represented as well as knowledge of the conventions and specifications which guide data base preparation. Prudence dictates effective mechanisms for data base inspection by the user. Appropriate implementation of data display procedures can provide this capability while also supporting routine analysis of data base content. This paper first illustrates a set of convenient mechanisms for the display of the elevation and planimetric components of geographic data files. Then, a new USAETL program in Computer-Assisted Photo Interpretation Research (CAPIR) is introduced. The CAPIR program will explore issues of direct data entry to create geographic data bases from stereo aerial photography. CAPIR also provides a technique for displaying geographic data base contents in corresponding three-dimensional photo models. This capability, termed superposition, will impact on the critical tasks of data validation, revision and intensification which are essential for effective management of geographic files.
