Abstract	There have been many published articles describing Interferometry algorithms for DEM generation in different applications. The best uncertainty achieved in most of these articles is greater than ±1 m calculating the elevation. Enabling scientists to gain experience with new techniques at low cost. Interferometry with synthetic aperture radar (InSAR) is one of the best technique for measuring the altimetry surface, its different changes and degradation over time, and the characteristics detailed of the surface. To take a better resolution of the surfaces, the authors propose their approach; it's to merge the results of the interferometry and data from segmentation of an optical high-resolution image. In this report, they describe a procedure for hybridisation of interferometry algorithm (InSAR) and the use of geospatial data from the image segmentation, with extraction of the building to calculate the zonal statistic parameter and mapping all segments comprising the highest elevations. This report is written in a step by step format to simplify the complicated steps described in this study, with a focus on the hybridisation instead of the interferometry. The tests of this method were carried out on several sites, and showed good results.
