全国第二次土壤普查一般要求完成社、县、地区、省(市)级成果图。在土壤普查全过程中,工作底图的制备及成果图的缩图拼接转绘工作量甚大。去年,我们在国家测绘总局研究所的帮助下,采用了缩微复印制图新技术解决了这个难题。 The second national soil census generally requires completion of community, county, district, provincial (city) level results map. In the whole process of soil census, the preparation of the work map and the drawing of the thumbnail of the result map are very heavy. Last year, with the help of the Institute of the State Administration of Surveying and Mapping, we adopted a new microlithographic mapping technology to solve this problem.
