Description

Internet-based hook reclamation field check management method
Technical Field
The invention belongs to the technical service field of surveying and mapping geographic information systems, and particularly relates to an internet-based hook reclamation field check management method.
Background
Along with economic construction's continuous development, the demand of each industry to the construction land is bigger and bigger, leads to the mole shield of people to be more and more outstanding: on one hand, the demand of the development of various industries on the land is increased, and on the other hand, the cultivated land is protected and the vital interests of farmers are maintained.
The increase and decrease of the hooks are effective ways for exploring and solving the problems, and the starting point is to arrange a large amount of idle construction land in the rural area into cultivated land through measures such as land demolition, land arrangement and reclamation and the like, and to promote comprehensive treatment of the field, water, road and forest in a matching manner, so that the reduction of the construction land in the rural area and the increase of the cultivated land are realized. The area that reduces the rural construction land is "gettered with the area that urban construction land increases," the construction land total amount does not increase, and the arable land area does not reduce and arable land quality grade does not reduce, and urban and rural land overall arrangement is more reasonable, improves the target of urban and rural economic development level. Meanwhile, by increasing or decreasing the hooks, saved land indexes are adjusted to be used in cities and towns, land income is obtained to feed back rural areas, and the problem of 'shortage of capital' in new rural construction can be effectively solved.
The on-site inspection of the hook-increasing and-decreasing reclamation land is mainly to check whether buildings in the land are dismantled or not, whether building rubbish is removed completely or not, whether the cultivated land area in the reclamation land is increased or not, whether the thickness of the cultivated land surface layer of the reclamation land meets the requirement or not, and the inspection result is used as an important basis for issuing the index of the hook by a higher-level executive department. The increase and decrease of the hook reclamation land has the characteristics of large quantity, wide distribution, small area of a single pattern spot and remote position, and brings great pressure to the work of checking and managing the reclamation land.
The existing increase and decrease couple reclamation check mode adopts paper drawing to look over on the spot more, and measuring instrument auxiliary actual measurements such as total powerstation, GPS, unmanned aerial vehicle, the camera cooperation is taken a picture and is collected evidence, and the mode of literal content record is checked and is collected evidence, though can master on-the-spot true condition, still has following drawback:
(1) position determination is inaccurate: by means of on-site checking of paper drawings, a checker cannot visually judge the current position of the checker and needs to have professional image recognizing and identifying capabilities;
(2) the examiner is required to have professional mapping knowledge: the field inspector can perform auxiliary actual measurement on the reclamation field through measuring instruments such as a total station, a GPS, an unmanned aerial vehicle and the like only by having professional surveying and mapping knowledge;
(3) the efficiency is low: the method carries out verification by filling in a paper form, drawing a sketch by hands, carrying a large amount of equipment on site, taking pictures by a camera and the like, and has low verification efficiency;
(4) the information recording is not standardized: the method is characterized in that verification and registration are carried out through modes such as character paper recording, and the like, so that recorded information and font styles cannot be standardized and unified, and the method is convenient to identify;
(5) photographing and obtaining evidence are not strict: because the scene picture shot by the camera can not record the shooting position coordinate and the shooting azimuth angle, the evidence obtaining mode is not strict;
(6) problems cannot be found on site in time: the coordinate data acquired by checking in the reclamation site can only be subjected to data analysis after going home, and problems cannot be found in time on the site;
(7) incoordination between internal and external industries is not tight: because no internal and external coordination mechanism is established, a management department cannot know the specific situation of the site at the first time, the internal and external work coordination is not tight, and the real-time and accurate decision can not be made according to the situation of the site;
(8) the work report is not intuitive: the contents of drawings, photos, coordinate points, character attributes and the like collected and drawn by reclamation check are independent of each other, no incidence relation is established, and the actual situation of each increase and decrease hook reclamation pattern spot cannot be visually and completely displayed when work is reported.
Therefore, an inspection scheme which is convenient to carry, simple to operate, complete in function, accurate in data acquisition and harmonious and compact in internal and external industries plays an important role in improving the inspection efficiency of the increase and decrease hook reclamation site.
