Embodiment 1

[0029] A database and its management system based on land survey, including:

[0030] (1) Data input: input various vector formats and graphic data into the system database;

[0031] (2) Change analysis: using the history database and the process database, the user can check the accuracy of the data according to the results of the process database, generate various statistical reports, and operate after confirming that it is correct. By merging the process database data, the original Layers are covered to obtain new soil layers, and the original soil layers are stored in the history library. The process library records the results of change superposition analysis and has a fixed field structure. With the operation of the program, The record value will change. The process library is a dynamic library, which is the data source for the system to perform various analyzes. The historical library stores spatial information and time information in one database, and stores historical ...

Embodiment 2

[0044] A database and its management system based on land survey, including:

[0045] (1) Data input: input various vector formats and graphic data into the system database;

[0046] (2) Data conversion: support mutual conversion between MapGIS and vector data in SHP, DXF, E00, VCT and other formats; support mutual conversion between MSI images and TIFF, JPG, IMG, BMP and other formats;

[0047] (3) Data check: accurately check out the topology, attribute and logic errors in the data, and support batch error correction. The data check backs up, restores and maintains the fields of the database, restores the mishandled data, and corrects the previous Data query and return visit.

[0048] (4) Data output: Output various reports according to the results of change analysis. The data output is based on standard framing or any administrative area to output thematic maps of land use, basic farmland, and cultivated land slope classification. The map output is JPG, TIFF, GIFF format....

Embodiment 3

[0051] A database and its management system based on land survey, including:

[0052] (1) Data input: input various vector formats and graphic data into the system database;

[0053](2) Change analysis: using the history database and the process database, the user can check the accuracy of the data according to the results of the process database, generate various statistical reports, and operate after confirming that it is correct. By merging the process database data, the original Layers are covered to obtain new soil layers, and the original soil layers are stored in the history library. The process library records the results of change superposition analysis and has a fixed field structure. With the operation of the program, The record value will change. The process library is a dynamic library, which is the data source for the system to perform various analyzes.

Abstract

The invention discloses a database established based on land survey and a management system thereof, comprising: (1) data input; (2) Change analysis; (3) data checking; (4) data output; (5) Data statistics. The system can complete the query, warehousing and statistics of different types of data, through the process library to achieve the superposition of the status quo data and change data, so asto analyze the direction and changes of various types of land, the report will be output; through the history database, the wrong operation data can be recovered, and the previous data can be queriedand visited back. The dynamic analysis of the data in different periods in the land change investigation management system has a strong pertinence, flexible and convenient data change processing tools, management and maintenance of a number of thematic data, which is conducive to information sharing and data maintenance.

Description

technical field [0001] The invention relates to a data management system, in particular to a database established based on land survey and its management system. Background technique [0002] Adhere to the principle of protecting basic farmland and strictly controlling the occupation of farmland for non-agricultural construction. Based on the goal of protecting cultivated land and improving comprehensive grain production capacity, we should further strengthen the protection of basic farmland and promote the transformation of cultivated land protection from quantitative protection to comprehensive management and protection of quantity, quality and ecology. In accordance with the unified requirements of guaranteeing economic development and protecting agricultural land, ensure land necessary for economic development, and rationally arrange the scale and layout of construction land. [0003] Since the land change survey contains a large amount of information and data, it is in...
