Spaceborne SAR images are combined with vector-based geospatial datasets published by Geographical Survey Institute (GSI) of Japan to discuss their applicability to disaster monitoring. RADARSAT fine mode image taken over Kobe city and JERS-1 SAR image taken over Mt. Iwate with Morioka city have been examined. City-block segments in digital map 2500 (spatial data framework) helps interpretation of RADARSAT fine mode image on urban area. It is difficult to distinguish roads and blocks on urban area of JERS-1 SAR image. SAR image can be used as a shaded map for disaster assessment in mountainous area. Integrating with GIS datasets would increase applicability of SAR imagery.
