Belgium, provided by their NMCAs. High-resolution satellite data from Ikonos or Quickbird is considered at a considerably lower priority, as these data are not extensively available, their cost is high, their resolution often insufficient, and research on road extraction from these data limited. 6. Analysis of the submitted results investigating different aspects including: completeness, reliability, accuracy, main advantages/disadvantages of each approach, input data requirements and other conditions, especially the sensitivity of the results to the selection of the parameters, delivery of attribute information, again including completeness, reliability, and accuracy. In addition, qualitative analysis of the results, including stereo superimposition of derived vectors, will be performed. The contribution of NMCAs in this process is necessary. The coordinating center for the analysis will be UniBw München. 7. Presentation of the main WG work with a workshop towards the end of its life in a practically oriented event maybe at Institut Géographique National (IGN), Paris, or Institut Cartographic de Catalunya (ICC), Barcelona. The WG work can also be presented and combined with other similar work at other appropriate events, such as by dedicated technical sessions. Cooperation with ISPRS, especially WGs IC II/IV, III/3,4,6,7,8, IV/7 is absolutely necessary, while ties with IEEE GRSS Data Fusion Committee, and Earsel SIG Data Fusion will be exploited with lower priority. 8. Publication of a final report within the OEEPE official publications. 9. Possible coordinated publication of several papers or a theme issue in an international journal. Time Plan If the project and WG is approved at the OEEPE June meeting, the first five action points above should be finalized by the end of 2002. The performance and analysis of test results should be concluded by August 2003. The project work and WG could be concluded by the end of 2003. Support and financing The support of NMCAs for provision of data and evaluation of test results, especially manual control, are an important prerequisite. To cover expenses related mainly to organization of events and use of part-time personnel (especially students) for data preparation and analysis, an amount of 3,000 Euro is proposed.

Test and reference data (incomplete, to be refined after project and WG establishment) Aerial film imagery Scale: 1:15,000, maybe also 1:30,000 Focal length: 30 cm, maybe also 15 cm Color; B/W can be derived from color images; maybe CIR in suburban areas Terrain covered: flat to hilly, rural, forest borders, small villages, suburban, maybe denser city areas although with not very high buildings. Land cover should include water bodies. Scanning: high quality geometry, scan pixel size 10-15 microns, good radiometry and color rendition Camera calibration protocol or interior orientation parameters. Exterior orientation, preferably from bundle adjustment, however without use of additional parameters. 247
