Geological Profile Method Based on Spatial Coordinates

Abstract

The invention discloses a method for actually measuring a geological section based on spatial coordinates, which relates to the field of geological surveying and mapping, and solves the problem that according to the existing method, a large number of people are required for field surveys in a layered rock layer area, and the calculation amount of drawing an unfolded map and a projected map is large and the process is cumbersome. question. The technical scheme adopted by the present invention is: the method of actually measuring geological section based on spatial coordinates, including drawing an unfolded map and drawing a projection map, and drawing an unfolded map includes: field geological surveying and mapping, determining a baseline, planning a section line, determining and numbering geological points, obtaining The spatial coordinates of the geological points, and the geological description and occurrence measurement; then construct the layered boundary surface, construct the expansion surface, etc.; then draw the expanded map, draw the terrain contour line, mark the azimuth, and finally obtain the expanded map of the measured geological section . To draw a projection map, first conduct field geological surveying and mapping, then organize the data, and finally obtain a projection map of the measured geological section. The present invention is suitable for use in areas with layered rock formations.

Description

technical field [0001] The invention relates to the field of geological surveying and mapping, in particular to a method for actually measuring geological sections based on spatial coordinates, which is suitable for layered rock formation areas. Background technique [0002] The measured geological section generally starts from the old stratum and proceeds to the new stratum, that is, the baseline points from the old stratum to the new stratum. In the process of field survey, it is necessary to determine the baseline and plan the section line, in which the section line needs to pass through and have good visibility conditions. During the survey period, it is necessary to collect statistics on the rock combination, stratigraphic division, stratigraphic sequence, rock metamorphism degree, contact relationship and the characteristics of each geological unit in the work area, that is, to collect data. After the survey is completed, the data will be sorted into projection diagra...
