摘要：Data fro m digital mapping project, which is carried out by the National Agency for Surveying and Mapping of Indonesia (Bakosurtanal), consists of seven main layers, i.e. relief (interpolated by digital elevatio n model), settlement, landuse (vegetation), transportation network, hydrography, ad ministrative boundary and geographical names. Analytical photogrammetry with p hoto scale 1:50.000 and 1:30.000 (for urban area) produce these data with some additional data from field check. Even the data is prepared mainly for mapping purposes, almost potential users request geographical data for GIS application, which need more external data not yet contains on aerial photograph, such as demography, soil, climate etc. So some additional data - and additional field surveys - are needed. But the search of expensive external data could be minimized by smart way, using so-called "Quasi-Analysis Techniques", using interlayer analysis and some modeling, which result in a so-called "Pre-Ready GIS". Objective of the research is how far the quasi-analysis techniq ues and pre-ready GIS can support decision-making, ho w is cost benefit ratio and where is the limit o f the method. The approach will be applied in some applications, i.e. determination of consider highrisk places along a street, optimal positions for microhydro power plant along a river, until a 3D-simulation of environment quality in a big city
