With the launch of Japan Aerospace Exploration Agency's (JAXA) Advanced Land Observing Satellite (ALOS) carrying the Panchromatic Remote Sensing Instrument for Stereo Mapping (PRISM) a large scale high resolution solution for efficient and economically viable digital elevation models may have been found.
This research project endeavored to create a methodology for extracting a high resolution digital terrain model from JAXA's ALOS PRISM imagery using ITT's ENVI 4.6 software suite and in particular the DEM Extraction Module.
As ENVI 4.6 uses a RPC and GCP based approach to the extraction of DEMs GCPs were collected in the field using differential GPS techniques. The GCPs were then used to create an RPC model for the imagery from which the DEM could be extracted using ENVI 4.6's DEM Extraction Module.
It was found using this methodology that a useful DEM could not be extracted from ALOS PRISM data at this time.
In the future different results may be achieved if a purchased RPC data is used and ITT continues to test and refine ENVI‟s compatibility with ALOS PRISM data
