A method to create a perspective image from Landsat TM data was descrived and the prospect was discussed. The digital terrain model (DTM) for the perspective image was a grid type. The ground elevation of it was interpolated at an interval of 40 meters for the TM data resolution from an originally produced DTM for Landsat MSS data with an interval of approximately 80 meters.
Compared with a perspective image from Landsat MSS data, this newly produced one from Landsat TM data informs us the detailed feature of land. Also new color composites in the perspective image, i.e., true color one, or middle infra-red one, can be produced because of the arrival of new band images in the TM data. Color perspectives drawn in these new color composition give us a kind of different feeling. True color perspective is free for our mind. Infra-red color one is fine to recognize the vegetation on the land. To the contrary, middle infra-red one gives us good views on the skirts of moutain but in the snow covered area of the summit.
Merits of the perspective image from Landsat TM data are prospectively presumed as below;
1. In the recognition of relationship between vegetation and topography.
2. In the recognition of river basin.
3. In the recognition of the topography of the land.
