Abstract

The invention provides an application method of a natural resource and planning data Application (APP), which comprises the steps of collecting natural resource and planning data, carrying out mapping on time-service natural resource and planning data to generate mxd files, utilizing a data processing tool to generate gpkg database files on a display object image layer, generating mbtiles grid tile data by using a graph cutting tool based on the mxd files, writing position information into the gpkg database files, carrying out association between the mbtiles grid tile data and the gpkg database through a natural resource and planning data Application (APP) setting function, reading data by the natural resource and planning data Application (APP), displaying a map through the mbtiles grid tile, and querying the gpkg database to realize attribute browsing. The invention can solve the problems of linkage of massive graphics and attributes, safe use of sensitive data and low data loading speed.

Description

Application method for applying APP to natural resources and planning data Technical Field The invention relates to the technical field of application software, in particular to an application method for applying APP to natural resources and planning data. Background The information construction of natural resources is continuous and deep, the application of natural resources and planning data based on a cloud terminal mode is very mature, but the application of the natural resources and the planning data based on government departments is mostly operated in a private cloud environment, and meanwhile, most of data cannot be browsed and analyzed on the Internet in order to ensure the safety of geographic space information due to the specificity of the natural resources and the planning data, and the user is out to research, field investigation, field command and scheduling and other scenes lack of data support. At present, under the scene, firstly, the natural resources and the space data are used and are mostly presented in the form of drawings, the characteristics of complex manufacturing process, low practicability and the like are presented, secondly, the small-range data screenshot information and partial statistical information are acquired by means of a mobile phone APP through an intranet-extranet interaction technology, the method solves the defects of a paper map to a certain extent, and meanwhile, the defects that the thematic map cannot be scaled and browsed steplessly, massive graphics and attributes are linked, sensitive data are used safely, and the data loading speed is low are also presented. Under the existing geospatial data protection system, how to realize fast browsing and efficient analysis of massive confidential or sensitive natural resources and planning data outdoors still has great difficulty, so new technical schemes are required to be provided for making up, improving and perfecting the existing data application modes and application technologies. Disclosure of Invention In order to overcome the defects of the prior art, the invention aims to provide an application method for applying APP to natural resources and planning data. In order to achieve the above object, the present invention provides the following solutions: an application method of a natural resource and planning data application APP, comprising: collecting natural resources and planning data; Carrying out map matching on time service natural resources and planning data to generate mxd files; generating gpkg a database file for the display object layer by using a data processing tool; generating mbtiles grid tile data using a graph cutting tool based on the mxd files; writing position information into gpkg database files; applying an APP setting function through natural resources and planning data, and carrying out association between the mbtiles grid tile data and the gpkg database; and the application APP of natural resources and planning data reads the data, displays the map through the mbtiles grid tiles, and queries gpkg database to realize attribute browsing. Preferably, the natural resources and planning data are vector data with spatial location information. Preferably, the data processing tool is a database format conversion tool.
