摘要：The paper analyzes the selection of main parameters of ALS system having an impact on acquisition of digital elevation models described by the assumed and exorbitant qualitative characteristics on the basis of airborne laser scanning project organized as a part of recommendations included in the Floods Directive in Poland. Such an analysis was the basis for determining conditions for a huge project,whose implementation is still ongoing, as well as its organizational and economic possibilities. Another subject for consideration was the scope of the planned works and time limits for their implementation that imposed the schedule of the project with respect to the efficiency of the work. Among the technical characteristics the authors investigated the density of the LiDAR points,georeferencing of point clouds,meteorological conditions during data acquisition and parameters describing the accuracy of the final products,namely digital elevation models,were also investigated. In such a complex project (the division of the whole project for subareas,many contractors, several final products and many stages of delivery product acceptance as well as quality control are key issues,whose effectiveness is proved by good organization,their scope and the adopted criteria.
