Electronic information system for earth monitor and method thereof

Abstract

The present invention provides an electronic information system and a method thereof, and constructs two sets of subsystems of field data collecting and indoor data processing. The field data collecting system is based on a Mobile GIS platform and is combined with GPS positioning, GPRS network, bluetooth communication, etc. The field data collecting system realizes high-precision positioning of earth monitoring, uses different methods for executing difference positioning, digital information collecting, eraser list constructing, photograph taking / camera shooting evidence obtaining and terrain hyperlinking for realizing electronic information of field land surveying at the state with / without VRS network. The indoor data processing system is based on SuperMap GIS developing platform and Browser / Server structure, and is combined with XML data interchange, spatial geographical coordinate projection switching, overlapping analyzing, etc. The indoor data processing system realizes multiple functions of indoor multi-source map data expression and operation, combined inquiry, report generation, land monitoring database updating, property formwork customizing, etc., and realizes electronic information of indoor land monitoring operation.

Description

technical field [0001] The present invention relates to the technical field of electronic informatization, in particular to an electronic informatization system and method for land monitoring, and more specifically to the rapid and high-precision acquisition of multi-source spatial data in land monitoring by using field portable equipment. On-site mapping, copying, adding and editing of attribute information, forensics and linking of photos and videos, office analysis of data, combined query and processing, report generation, database update, customization of attribute templates, etc. Background technique [0002] At present, the method of field investigation in the land monitoring industry is: to find suspected illegal and illegal land use through reporting information, remote sensing image data analysis, etc., and the monitoring personnel will take the relevant paper-based land use status map, image map, and land approval documents. On-site measurement and data recording a...

Problems solved by technology

The disadvantages of the above method are: (1) it is necessary to prepare and carry a variety of paper maps, which brings a lot of inconvenience to the field inspection operation; holding various paper maps and data materials to the field is inconvenient to carry and easy to be damaged; (2) The remote sensing monitoring method currently only monitors some cities, which cannot meet the needs of the vast villages and towns in China; it is monitored once a year, and the real-time performance is poor; it is greatly affected by climate and natural conditions, and it is not suitable for mountainous areas and rainy and foggy areas. Applicable; the resolution is not high, and the mapping accuracy is difficult to meet the requirements of land monitoring in developed areas; (3) the cost is high, and the personnel technical requirements are high; the measurement with a tape measure cannot be absolutely positioned, and a reference object is required when measuring the inflection point of ground features. Field personnel are required to have good professional knowledge in surveying; (4) mainly manual work, time-consuming, slow, many steps, complicated procedures, low data quality, and labor-intensive to measure the location, area, and shape of illegal land use; ( 5) The site cannot conduct qualitative and quantitative analysis of suspected land use in real time, and output field law enforcement results in a timely manner, resulting in a long operation cycle; (6) The internal industry cannot grasp the land monitoring situation of the external industry in real time, which is not conducive to fine management; (7) Internal industry data calculation , The workload of statistics and sorting is heavy, and it is difficult to form systematic data; the sharing of land monitoring data is poor; (8) the field work cycle is long, and the workload of internal statistics is heavy, error-prone, and not intuitive. From monitoring to illegal land use to filing and law enforcement The cycle is long, and it is difficult to eliminate the phenomenon of illegal land use in the bud in time

[0003] In recent years, some new land survey technologies have emerged, such as information collection technology using portable equipment, high-precision network positioning technology, etc., but the problems of the above-mentioned technologies are: (1) The high-precision positioning of the above-mentioned new technologies is based on the Under the premise that the survey area covers VRS network and GPRS network, most villages and towns in China have not covered VRS network or even GPRS network, but the material basis for our country's survival - the basic farmland is in the countryside, and the momentum of various illegal land use must be effectively curbed , the goal of keeping the 1.8 billion mu of arable land that our people depend on can be effectively guaranteed; (2) Some of the above technologies also need to use a total station with high-precision positioning, and the operation is complicated, but land monitoring personnel at the grassroots level in villages and towns often do not have the skills It is difficult to grasp the background of surveying and mapping; (2) The above-mentioned technologies and equipment are not designed for the land monitoring business in villages and towns, and cannot meet some specific needs of land monitoring, such as taking pictures, video evidence collection and superlinking with ground features, navigation, (3) Most of the above-mentioned technologies only provide basic field data collection functions, while for office data, the existing GIS software on the market is mostly used for processing, and There is no targeted and more complete office data processing system and method
