Abstract: With the wide application of remote sensing data in natural resource surveys, there is a higher demand for mass production of "one map" of multi-source high-resolution remote sensing images. This paper takes Yinhai District, Beihai of Guangxi province as test area and uses the "RS + GIS + Photoshop" algorithm of Pixel Engine software. First, according to the characteristics of multi-source and high-resolution remote sensing satellite data, the corresponding data processing process is formulated, and the single scene DOM is produced automatically. Then, taking the county-level jurisdiction as the unit, the county-level jurisdiction DOM produced quickly in batches. Finally, from the two aspects of production precision and speed, the DOM results produced by this method are compared with the manual processing results. By analyzing the feasibility of the method, it turns out to be a fast and effective production method of multi-source high-resolution DOM.

Key words: multi-source high-resolution, remote sensing image, DOM automatic processing, batch processing
