[0035] Such as Figure 1-3 As shown in one, the GPS mobile law enforcement monitoring system for land and resources of the present invention includes a GPS handheld integrated machine 1 and a background computer 2. The GPS handheld integrated machine 1 performs data collection by receiving satellite signals outdoors, and the GPS handheld integrated machine 1 It is connected to the background computer 2 through a USB interface for data synchronization. The background computer 2 is equipped with a mobile law enforcement monitoring data processing module 3; the GPS handheld integrated machine 1 includes an operating system platform 4, a camera 5 and a GPS receiver 6, which can operate The system platform 4 is connected to the camera 5 and the GPS receiver 6 respectively. The operating system platform 4 is provided with a memory 7 which stores a mobile law enforcement monitoring module.
[0036] The GPS mobile law enforcement and monitoring methods of land resources in the present invention mainly include two methods, namely, satellite law enforcement and dynamic inspection methods. Among them, such as figure 2 As shown, the law enforcement of satellite films includes the following steps:
[0037] 1) The staff turn on the GPS handheld machine 1, open the mobile law enforcement monitoring module stored in the memory 7 of the operating system platform 4, load the monitoring pattern information in the satellite image, and receive the GPS signal through the GPS receiver 6, and at the same time it will receive The GPS signal is converted into position information, and the position information is sent to the mobile law enforcement monitoring module in the memory 7. The mobile law enforcement monitoring module superimposes the position information on the satellite for real-time positioning, and displays the operation on the display interface of the GPS handheld machine 1. The relative position between the location and the law enforcement scene;
[0038] 2) Field inspection: After the staff arrive at the law enforcement site, they use the GPS receiver 6 to read and analyze the GPS signal for real-time single-point positioning, and transmit the signal received by the GPS receiver 6 to the memory 7 in the operating system platform 4 for storage The mobile law enforcement monitoring module, which collects geometric information of points, lines, and planes on the detected illegal or suspicious objects. The mobile law enforcement monitoring module has a variety of methods for taking points and mapping, including GPS taking points, screens Take points, vector base map take points, image base map boundary information extraction, various surveying and mapping auxiliary methods take points, and the above-mentioned various methods of taking points are combined with each other; at the same time, the collected data information is identified by the land use category, and the land use situation is recorded; Enter and modify map attribute information. When the illegal land belongs to multiple types of land, collect and monitor the dividing line of the map according to the boundary of the land type, and collect the record points at the inflection point of the boundary line through continuous point sampling and polygon sampling. Coordinates, when the field collection task is finished, the above information is automatically saved in Tra format to the memory 7 of the operating system platform 4;
[0039] 3) In-house processing: load the satellite image with the monitoring map in the mobile law enforcement monitoring data processing module 3 of the back-end computer 2, and at the same time receive the Tra format data collected by the field inspection through the USB interface, and display the corresponding data in categories and colors Monitoring map spots and collected point, line and surface data; according to the recorded land use category of illegal plots, plots containing multiple land types are divided into a single land type according to continuous stepping lines; for the same land type Combine adjacent plots; delete plots that are not illegal; export the data collected by field inspections and the segmented and merged suspected illegal pattern data into CAD or graphics format or specified text coordinate files; The mobile law enforcement supervision data processing module 3 again loads the satellite image with the monitoring pattern, and verifies it with the suspected illegal pattern that is segmented and merged by the field inspection, and superimposes the image, and the verification result is made into a suspect with a map creation tool Use illegal maps and print them;
[0040] Such as image 3 As shown, the dynamic inspection specifically includes the following steps:
[0041] 1) Field inspection: the staff arrive at the area under their jurisdiction, turn on the GPS handheld, turn on the GPS receiver 6, receive satellite signals, and at the same time convert the received GPS signals into position information, which is displayed on the GPS handheld 1 The current location is displayed on the interface, and the inspection starts. The mobile law enforcement monitoring module stored in the memory 7 of the operating system platform 4 records the trajectory of the inspection in real time, and automatically saves it in Tra format to the memory 7 of the operating system platform;
[0042] Use the GPS receiver 6 to read and analyze the GPS signal, realize GPS real-time positioning, check and monitor the pattern on the spot, and transmit the signal received by the GPS receiver 6 to the mobile law enforcement monitoring module in the memory 7, and the mobile law enforcement monitoring module monitors the monitored data. Illegal or suspicious objects are collected for point, line, and surface geometric information. The mobile law enforcement monitoring module has a variety of ways to take points and map, including GPS points, screen points, vector base map points, and image base map boundaries Information extraction, various auxiliary methods of surveying and mapping, and the combination of the above-mentioned methods; at the same time, check the illegal land on the spot, collect the single-point coordinate information of the suspected illegal building, and record the serial number (id), latitude ( Latitude), longitude (Longitude), altitude (Altitude), position accuracy (PDOP), vertical accuracy (VDOP), horizontal accuracy (HDOP), start time (starDateTime), remarks (remark) and other information. Identify the type of land use, record the land use situation, enter and modify the attribute information of the map at the same time, use the camera 5 to take pictures and video for evidence collection; collect data at the boundary of the illegal plot, and collect the spatial location of a single point, Continuously pick points to collect boundary lines, polygon pick points to collect the boundary range of illegal plots, record the length of the boundary line and plot area, and then automatically save the collected information in Tra data format to the memory 7 of the operating system platform;
[0043] 2) In-house processing: The Tra format data stored in the field inspection is transmitted to the back-end computer 2 through the USB interface, and the computer 2 converts the received Tra format data into map data, and displays the corresponding monitoring patterns and collected data in different colors. Point, line and surface data, showing on-site photos and on-site video for evidence collection; then save the processed dynamic inspection trajectory and save it as a dynamic inspection drawing, export it into CAD or graphic format or a specified text coordinate file, and finally export it into a table Save or print out the diagram.
