DEM, resently has been widely used in different fields, especially in photogrammetry for topographic map production. One of the problems of DEM is how to collect data accurately, efficiently and comprehensively. Prgressive samling conceived by Makarovic is considered a more promising approach for DEM data acquisition.The basic principle of progressive sampling is progressive grid densification starting with sampling in a coarse homogenous grid and proceeding to a finer sampling in partial grids. Data collection and analysis are performed interactively. The result is a square grid in variable density, locally adapted to the roughness of terrain relief. Progressive sampling allows for semi-automatic operation, i. e. , computer controlled Ⅹ. Y-positioning of the measuring device of a photogrammetric stereaplotter and manual height setting (Z-positioning) by the operator. Progressive sampling can be done either on an analytical plotter or on an analogue stereoplotter interfaced with a computer by a feedback loop. Progrssive sampling has the potential of meeting the requirements on sampling, i.e., to collect terrain relief data accurately,comprehenslvely and store them in a favourable structure for later efficient process.Based on the principle of method, corresponding parameters of progressive sampling are experimetally investigated in this paper. Through the analysis of testing results, the influences of the sampling parameters on the accuracy of DEMs and the accuracy of contour lines derived from DEM, and the interrelationship between different parameters are proved. According to this, some conclusions are drawn with respect to the experiments performed in the paper, and a tentitive procedure is proposed in which the values of sampling parameters are determined by considering the accuracy specifications of topographic map and the measuring error of height, that is: under the assumption of accuracy specification for derived contour lines requiring that the standard error of checked contour points should not be larger than 1/3 of the contour interval, a proper minimum grid spacing of progrossive sampling can firstly be defined by analyzing the comprehensiveness of equispaced sampling for different regular spacings yielding a standard error of DEM of 1/5 of the contour interval. A threshold value of second difference equal to the contour interval can be chosen if the contour interval is not smaller than 5 times the standard error of measuremnet.

渐近取样法是Makarovic教授首先提出的一种DEM取样方法。本文依照此法的原理对有关参数进行了试验性的研究。通过对试验结果的分析,了解了这些参数的变化对DEM精度和从DEM得到的等高线精度的影响情况,以及参数与参数间的相互影响情况。在此基础上提出了根据地形图的精度要求和实际量测误差确定取样参数值的建议。

The Yellow River Delta area is located in the east of sandong Province east of China. Floods in this area are caused by two hydrological conditions. One is the rairstorm in the late summer and early fall, and another is the ice run in the winter. In the past more than 130 years, the floods happened about fifty times (including serious ten times) in the delta area. The flood risk will continuosly exist if the water and ice regimet and silt deposit can not be changed basically. So the WIRWIS has been established...

The Yellow River Delta area is located in the east of sandong Province east of China. Floods in this area are caused by two hydrological conditions. One is the rairstorm in the late summer and early fall, and another is the ice run in the winter. In the past more than 130 years, the floods happened about fifty times (including serious ten times) in the delta area. The flood risk will continuosly exist if the water and ice regimet and silt deposit can not be changed basically. So the WIRWIS has been established by using ARC/INFO GIS. It is very important for developing agriculture, oil industry, and protecting ecologic environment in the delta area.The design of the WIRWIS is first topic. This topic describes a goal and application modules of the WIRWIS. According to the goal, the display module of maps and geo-data, the module of map query, the analytical module and the evaluation module of flood loss have been designed.The second topic is data organization. It is crucial for establishing database of the WIRWIS. So, the database is divided into some layers. They are terrain, water, Yellow River course, landuse, residence, oilwell, and factory etc. Each layer stores only one type of geographic information and related attribute information. In this way it is easy for maintaining and using.The third topic is the establishment of the WIRWIS method. Data collection is a basic step of this topic. By using ARC/INFO GIS, all geographic and stat istical data have been input into-the computer. In order to build the database, geographic attribute information has also been input after coverages (files in ARC/INFO) processed.Finally some application study has been done. From a 3-D DTM the best flood discharge route has been found. After a flood discharge zone created, submerged loss can be evaluated. So a rescuing plan can be made soon.
