This project investigated the potential of using 1:50 000 digital data and Landsat TM imagery to derive and revise the 1:250 000 NTS maps, and digitized aerial photography to revise the 1:50 000 NTS maps. The UNIX based CARIS system was used for both the derivation and the revision of the prototype data sets. For the derivation of the 1:250 000 map, data generalization techniques were applied to a 1:50 000 data set. The revision of vector data from both Landsat TM image and digitized aerial photography was performed by integrating the raster images and the vector map data. Change detection was performed visually and new vector data collected. The procedures followed and the results obtained are presented. RESUME Cet article décrit le projet-pilote de révision cartographique de la Série de cartes topographiques nationales qui fut exécuté au Centre canadien de cartographie. Le projet-pilote a étudié les possibilités d'utiliser des données numériques au 1:50 000 et des images Landsat TM en vue de recompiler et de réviser les cartes au 1:250 000, ainsi que les possibilités d'utiliser des photographies aériennes numériques pour réviser les cartes au 1:50 000. Le systéme CARIS, articulé sur UNIX, fut utilisé pour la recompilation et la révision des ensembles de données du prototype. Des techniques de généralisation des données furent appliquées à l'ensemble de données au 1:50 000 pour obtenir la recompilation de la carte au 1:250 000. La révision des données vectorielles des images Landsat TM et des photographies aériennes numériques fut accomplie en intégrant les images raster et les données cartographiques vectorielles. L'identification de changements fut accomplie visuellement et de nouvelles données vectorielles furent recueillies. Les procédures suivies et les résultats obtenus sont présentés. 1.0 INTRODUCTION The Canada Centre for Mapping, (CCM), is responsible for the production and maintenance of the National Topographic Series (NTS) maps for Canada. The NTS consist of maps at two scales: 1:250 000 and 1:50 000. Canada has complete coverage with the 1:250 000 maps, which have also been scanned for conversion to digital form. Although these 914 maps are in digital form, the data is currently only being used for GIS applications, not for map revision. These maps continue to be manually revised. The coverage of Canada at the 1:50 000 scale is approximately 92% complete, with a combination of digital and analogue maps. Of these 11, 931 maps at the 1:50 000 scale, 20% have corresponding digital data, either from stereocompilation or scanned reprographic material. This percentage of digital data is increasing as more new maps are stereocompiled and existing anologue maps revised by digital recompilation or scanned and converted to digital data. All of the digital data for the NTS maps is archived in the National Topographic Database. The only digital revision currently being used is the stereo recompilation of entire map sheets. At the 287
