Roads appearing on the map and in the imagery are modeled as active contours, and their positions in the image determined by energy minimization on an energy surface calcu-lated as a function of edge strength. The rest positions of the contour models in the image are required to be projections of their map positions, thus maintaining the known shape of the roads. The image orientation parameters are refined as part of the road location process, yielding a simultaneous, consistent determination of the road locations and the imaging parameters and allowing well-determined features to assist the location of weaker ones.

In this paper, we discuss the application of vanishing points for the identification of vertical and horizontal lines, and the use of multiple views for verification of these lines. The vertical and horizontal attributions are used to constrain the set of possible building hypotheses. Preliminary results exploiting these attributions are described.

For the most part the scale, size, and orientation of specific features are usually expressed in terms of image pixel size. Given the use of nadir and near-nadir mapping photography this has not severely impacted the development of several techniques at a variety of institutions for building detection, road network extraction, and other specific man-made objects. It is not too unfair to say that the inherent difficulties involved in achieving robust automated object detection and delineation have overshadowed any errors due to lack of rigor in the modeling of the image acquisition. In this paper we will develop several of these issues and discuss how the use of photogrammetric cues will play a major role in future systems for automated cartographic feature extraction.

Early systems, painstakingly tweaked to work in a very limited fashion on small images, have given way to sys-tems which produce credible results in situations representative of production environments. While no existing automatic system is yet ready for incorporation into a production environment, significant strides have been made toward this goal. Semi-automated systems, with significant man-in-the-loop capabilities, continue to be developed by photogrammetric workstation vendors. However, a fundamental requirement for system development, and an absolute prerequisite for production applications, is the rigorous evaluation of automated system performance. Indeed, without meaningful evaluation, we can hardly be said to be doing science. Rigorous evaluation requires the definition of a set of metrics, relevant to user requirements and meaningful in terms of ...

This acquisition resulted in hyperspectral data with a nominal 2 meter ground sample distance collected with 210 spectral samples per pixel. This paper describes current quantitative classification results for man-made and natural materials using 14 surface material classes over selected test areas within Fort Hood. We discuss the issues encountered in radiometric effects due to changing solar illumination and atmospheric conditions during the acquisition. We also describe our approach to image registration and geopositioning, using a full photogrammetric block adjustment solution.

Six operators used RoadMAP in both manual and semi-automated modes, as well as BAE Systems ’ SOCET SET ® , to extract roads in four image test areas. An in-depth statistical analysis was performed on the timing results, with the main conclusion being that the performance differences among the three systems were not statistically significant. However, the evaluation highlighted a number of factors other than intrinsic feature extraction competence that affected the results and which point to the potential for significant engineering improvements.

Both polynomial and interpolative platform models were tested; the polynomial model generally performed better than the interpolative model without lines, but not as well as the interpolative model with straight line constraints. The greater flexibility of the interpolative model makes it better able to describe complex platform motion and to utilize the geometric strength given by the straight line constraints, at the expense of increased sensitivity to uneven point distributions or bad points.
