JX-4全数字摄影测量系统工作站在进行DEM数据采集时，可以使用三维数据采集法来对DEM数据进行采集，三维数据采集法有多种测量方法，它在进行空间方面的测量和分析时能够更为直观的表现出各项数据。也正是因为采用了三维数据采集法，我们可以通过使用正确的构面、水域处理等采集方法来尽可能的减少在采集数据时可能出现的差、错、漏等问题，能够迅速准确地提高工作效率。%JX-4 digital photogrammetric workstations can use three-dimensional data collection method during the DEM data collection. Three-dimensional data collection has a variety of methods, during the measurement and analysis of space, it can be more intuitively present data. Through the three-dimensional data collection method, we can correctly use dimensions, water treatment and other collection methods as far as possible to reduce the differences, errors, leakages and other problems, quickly and accurately improve efficiency.
