Abstract
High resolution digital elevation models (DEMs) have been used in many applications such as civic planning, military navigation and natural hazard risk assessment. DEMs can be derived using various remote sensing techniques, such as photogrammetry, radar interferometry (InSAR), airborne laser scanning (ALS) and high resolution space imaging. This paper refines the methods of height estimation over diverse terrain using a combination of ALS and InSAR data, including Shuttle Radar Topography Mission (SRTM) and repeat-pass InSAR DEMs. This study aims to generate fine resolution DEMs from ALS and InSAR data for the study area. The variable topography of the region and proximal urban interface provides a good test bed for DEM generation techniques. The derived DEMs are examined using ground survey data with the aid of GIS.
