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...
