Abstract

The invention discloses a method for quickly drawing a farmland electronic map. According to the method, a high-definition satellite map with a high definition is adopted for reference according to the fact that the high-definition satellite map has longitude and latitude information, farmland zone boundary point longitude and latitude information measured through a GPS instrument is used to correct geographic coordinates of the high-definition satellite map, and the farmland electronic map is drawn. The method is low in cost, short in cycle and high in precision; by use of the method, the farmland electronic map with high precision can be quickly drawn, and meanwhile the research efficiency of GIS-based agricultural application research is improved.

Description

technical field [0001] The patent of the invention relates to a method for quickly drawing an electronic map of farmland, which belongs to the technical field of electronic map drawing of farmland. Background technique [0002] At present, the agricultural map is a thematic map that mainly shows agricultural production conditions, distribution, development and planning. Large-scale agricultural maps are used to manage agricultural production, implement and plan farmland infrastructure, resource surveys, and reclamation of wasteland. Agricultural maps at small and medium scales are used for scientific research, teaching, and general reference. [0003] Since the 1990s, with the development of 3S spatial information technology, agricultural application electronic technology, crop cultivation related models, ES, SS, DSS, ICS, and artificial intelligence technology, precision agriculture has become the most attractive frontier in the 21st century. It is one of the research fie...
