This paper introduces the mapping workflow of using new digital photogrammetric cameras with GPS/IMU in mitigating natural hazards for the Aerial Survey Office. In the text, we have included detailed descriptions on the procedures of image acquisitions, high resolution and multi-spectrum ortho-image productions, interpretations, digitizations, and data provisions. We also illustrate how these procedures were applied to mitigate catastrophes occurred in recent years, such as "Alisan Fire", "88 Flood", and "Chiahsien Earthquake". The results indicate that high-resolution digital aerial images can be applied to the interpretation of forest fires with NDVI images, production of digital terrain model, change detection, and mitigation of natural hazards.
