Problems solved by technology

However, the existing overlay often collects the overlay result data of multiple layers of data into a new layer of data storage, resulting in too finely divided graphics overlapping and cutting, and data redundancy is inevitable, especially in targeted actual work, which affects work efficiency.

Embodiment

[0078] first step:

[0079] First, define the metadata table of the map library for construction projects, which is used to store information such as the library name, library collection name, resource class code, library number, scale, and spatial reference, and set the user interface for setting the parameters of the library creation, such as figure 2 , to associate these information stores with metadata tables;

[0080] Then define the sub-layer type table contained in the map library for construction projects, and implant the library number into the layer as a field attribute of the layer type to keep the relationship between the two consistent; define the layer structure table contained in the map library for construction projects , to specify the field type and length of each layer;

[0081] Finally, according to the spatial reference information of the existing land use status database, a construction project map library with the same scale and spatial reference is cr...

Abstract

The invention discloses a method for automatically extracting a planned selected site of a construction project, which comprises the following steps of: 1) creating a map library for construction projects land with consistent spatial reference information of land use status data; 2) extracting a red line range of the planned selected site of the construction project; 3) taking the red line range of the planned selected site as the boundary to automatically extract the land use status data in the boundary; and 4) performing planned site selection on the appointed construction project, performing area statistics according to the classification of land use, and outputting a result of automatic extraction of the planned selected site of the construction project. The method reduces human-computer interaction during the preliminary review work of land for the construction projects, and greatly improves the efficiency of the preliminary review work. The method has wide application prospect in the field of planning and the field of cultivated land requisition-compensation balance or standard farmland requisition-compensation balance.

Description

technical field [0001] The invention relates to a method for automatically extracting proposed sites for construction projects, which has very important practical significance for the field of land use planning, and also has certain reference value for other related fields. Background technique [0002] The site selection of construction projects is the key to the implementation of land planning. The site selection and layout of construction projects in the planning area are directly related to the nature, scale, layout and implementation of the planning of an area, and are also related to the smooth implementation of construction projects. , is a very important link. [0003] According to GB / T50280-98 "National Standards of the People's Republic of China", the construction project site selection opinion is defined as "the legal certificate of the site selection and layout of the construction project issued by the urban planning administrative department in accordance with t...
