This rotated color-IR digital orthophoto map sheet was created by Photogrammetric Data Services, Inc., using Vision International's SoftPlotter™ digital photogrammetric system. 1:14000 scale photography scanned at 500 dpi using a Vexcel VX3000 scanner. Map composition performed with Erdas Imagine and plotted with an Iris plotter. SoftPlotter™ offers rigorous registration of various types of imagery to ground control, including standard frame photography and SPOT satellite imagery (1A and 1B, panchromatic and multispectral); precise measurement of three-dimensionals coordinates from stereoscopic images; data collection of Digital Terrain Model (DTM) data.

959 Conceptual Framework of a Generalized Roaming Scheme
Toni Schenk and Charles Toth
The information in which roaming is performed is extended from imagery to include vector data, DEMs, databases, and design data extending over an entire project.
965 Automated DEM Extraction and Orthoimage Generation from SPOT Level 1B Imagery
N. Al-Rousan, P. Cheng, G. Petrie, Th.Toutin, and M.J. Valadan Zoej
Geometric accuracy testing and the generation of DEMS and ortho-images of desert terrain within a fully digital photogrammetric environment are described.
975 Image-to-Image Registration by Matching Area Features Using Fourier Descriptors
and Neural Networks
Yi-Hsing Tseng, Jin-John Tzen, Kei-Pay Tang, and Shin-Hung Lin
An automatic method of image-to-image registration, which may be applied to register overlapped images of a scene from different views and dates, is presented.
985 Semi-Automatic Linear Feature Extraction by Dynamic Programming and LSB-Snakes
Armin Gruen and Haihong Li
A Human operator identifies the object from an on-screen display of a digital image, selects the particular class to which this object belongs, and provides a very few coarsely distributed seed points.
997 Evaluating the Potential of the Forthcoming Commercial U.S. High-Resolution
Satellite Sensor Imagery at the Ordnance Survey®
Helen M. Ridley, Peter M. Atkinson, Paul Aplin, Jan-Peter Muller, and
Ian Dowman
The potential for creation of DEMs, topographic mapping, 3D modeling, and land-use classification from 1-m panchromatic and 4-m multispectral satellite imagery was investigated.
1007 Automatic Interior Orientation of Digital Aerial Images
Thomas Kersten and Sivio Haering
The method, based on a modified Hough transform for localization of fiducial marks and least-squares matching for precise measurement, is described.
1013 The Architecture of a Softcopy Photogrammetry System
Lewis N. Graham, Jr., Kyle Ellison, Jr., and C. Steven Riddell
Imagery must be displayed with very high geometric accuracy at all times, including the already processor intensive operation of dynamic roam.
