Abstract

The invention belongs to the technical field of geographic information methods and discloses a GIS data editing method which comprises the translation steps that a geometric figure needing translationis selected, an anchor point and an anchor point range are displayed after a translation tool is clicked, a finger clicks the geometric figure needing translation, and if the clicking position of thefinger is within the anchor point range, the anchor point is pressed, and a geometric object is moved; otherwise, nodes in the graph are reselected as anchor points, and the finger clicking positionis continuously judged until the finger clicking position is within the range of the anchor points. According to the method, surveyors can conveniently edit and correct drawn geometric figures on sitein field work, and the field work data editing efficiency is improved. According to the method, editing operation of point, line and surface graphic objects can be carried out through the functions of node movement, node addition, node deletion, trimming, line segmentation, surface segmentation, combination, public edge automatic tracking, cutting and the like.

Description

technical field [0001] The present invention generally relates to the technical field of geographic information methods, in particular to a GIS data editing method. Background technique [0002] With the continuous development of mobile geographic information method GIS, the GIS data rendering, collection and editing platform based on the large amount of mobile terminal data is often used in field data survey and collection work. For field data survey and collection, staff often need to carry remote sensing images and corresponding office data to the field for data collection and editing; when editing data, since the screens of existing handheld mobile GIS terminals are mostly small, the interactive mode It is relatively simple, and it is very difficult for field personnel to operate and edit GIS data on the screen with fingers; if a mobile GIS terminal with a single interactive mode or cannot provide a complete collection and editing process module is used, the efficiency o...
