The situation of geological disaster prevention and control in our country is very serious. The application of remote
sensing technique in geological disaster monitoring has been more than 30 years, and which has got many successful
experiences. Remote sensing technology applications has shown enormous potential in investigation, evaluation, forecast
and warning, and relief aspects of geological hazard research, and has been more and more attention to, for remote
sensing technology is an high technology means with the ability of big range, all-weather, and dynamic monitoring the
spatio-temporal changes of disasters. In the 2008 Wenchuan earthquake disaster, remote sensing technology played a
huge role in the emergency response of the earthquake damage. But it has also exposed some problems that urgent needs
to solve, the most critical problem of which is lacking of fast and efficient methods for disaster information extraction
from remote sensing image data. This problem is also the key technical problems needs to solve and improve in the work
of remote sensing application for geological hazard emergency investigation and evaluation. An interactive interpretation
method platform based on Grab Cut segmentation was proposed in this paper, and used in interaction extraction of
geological hazard information from remote sensing image. Based on ArcGIS Engine second development environment
and in the .net framework, the interactive interpretation method utilize Grab Cut segmentation algorithm was developed.
Because of Grab Cut image segmentation algorithm exploiting the texture and edge features, using this method can
obtain ideal interpretation results and better improve interpreting efficiency, with less interactive steps.
