Abstract

Abstract Alos satellite is one of the natural resources satellite that could be used in 3D applications. The problems that be taken in generate 3D model with satellite imagery are the model always be formed as Digital Surface Model (DSM), not Digital Terrain Model (DTM), Digitallen HöheModellen (DHM), Digital Geoid Model (DGM) or Digital Elevation Model (DEM). The reference system of 3D model that are produced by Alos satellite image still as surface for z axis, for x axis and y axis has been closed to 2D reference system in some certain datum and system of map projection. In case, it needs a research for observating the accuracy and precision of Alos satellite data using a least square adjustment of parameter methods. The results of this research will be used as reference for next research to invent a way for changing DSM from Alos satellite image to be DEM, DTM, DHM, DHM, and DGM digital-automatically. It is a new innovation of differentialing technical of 3D model. A differentialing technical from DSM to be DEM could be done with least square adjustment in parameter methods. It calls DSM2DEM*. This new innovation methods for differentialing DSM2DEM. In that study cases, differentialing technical that are used be divided for two class, that are lowland area and highland area. Differentialing in that two class use similar methods, just is differentiated in sum up of researching points that are used. In this research study of cases are in highland area and lowland area. In highland area uses minimize 14 researching points and in lowland area uses minimize seven researching points. That differentialing technical are done in Alos images. In other satellite images, photos, videos that study in highland and lowland area also use this methods for differentialing DSM2DEM. Order level that are used as research points will influence the quality of its data accuracy and precision.
