Technical Field

The invention relates to the technical field of electronics, in particular to an intelligent multi-measurement-in-one geographic information system.

Background

In recent years, along with the fact that the requirements of surveying and mapping projects on data results are higher and higher, the data volume is larger and higher, the requirements for database construction and warehousing are higher and higher, the existing surveying and mapping software can not meet the requirements far away, a project is often made with multiple kinds of software and multiple platforms, surveying and mapping operation software and database construction software are basically separated, particularly, after the surveying and mapping project operation of real estate registration at the present stage is completed, a righter is required to sign and confirm a survey result, the existing operation software is used for outputting printed data through software after the survey is completed, and a farmer conducts warehousing after signature confirmation, so that the signed data and the result after the warehousing are inconsistent, and the project quality problem which is difficult to overcome is caused.

The reason is deeply studied, mainly because the current domestic surveying and mapping operation software is developed secondarily by taking an AutoCAD product of American Autodesk company as a bottom layer, the AutoCAD software is a product which runs for decades and is mainly designed for drawing, the drawing function is very strong and stable, which is also the most important reason that the drawing function is difficult to replace, the AutoCAD software stores and edits data in a dwg file format, and the functions of library building, topology checking, inquiring, counting and the like are weak. The library building software is usually developed secondarily by taking ArcgIS Arcengine of American Esri company as a bottom layer, the ArcgIS software is the leadership of the global GIS industry, and the domestic best development scheme is developed secondarily by the ArcgIS software, so that the defects that the ArcgIS has a weak graph editing function, a huge product design function and weak editing efficiency are overcome.

In order to complete the surveying and mapping project efficiently, an integrated system for editing and building a library is needed. After the editing and inputting of the mapping data are completed, the library building process is completed only by performing quality inspection and repairing, and the printing data signature is output after the library building is completed.

In addition, under the current major trend that China pays attention to the construction of domestic autonomous software, and under the condition that the surveying and mapping industry relates to national major security secrets, the development of domestic surveying and mapping-GIS bottom layer software is imperative.
