Abstract
The invention relates to an integral ground feature mapping working method based on partitioning. The integral ground feature mapping working method comprises the following steps: (1) partitioning ground features: partitioning the ground features to be detected to form measuring units, wherein all the measuring units take a cadastral street, a lane boundary line, a water system central line and a road central line as boundary lines so as to maintain the integrality of the ground features and corresponding side boundaries between the adjacent measuring units are overlapped; (2) carrying out field measurement; and (3) carrying out office work treatment. Aiming at a current working manner, the integral ground feature mapping working method is convenient for field annotation/mapping and the edge snapping work amount of office work is reduced; the partitioning is reasonable so that river-spanning and road-spanning work is reduced to the greatest extent and result data is prevented from being cut; the edge snapping work amount is eliminated basically and the integrality of the ground features is maintained to the greatest extent. The integral ground feature mapping working method based on the partitioning is applicable to a field working mode; the edge snapping work amount is nearly zero and the edge snapping work amount of traditional framing data accounts for 1%-3% of the working amount of a whole picture; the integrality of the ground features is effectively maintained and the integral ground feature mapping working method is applicable to data management.
Description
Technical field
The invention belongs to mapping operation field, especially a kind of complete atural object mapping operational method based on subregion.
Background technology
At present, China basis mapping work pattern can be summarized as substantially: measure/repair survey-interior industry by the map sheet field operation and process-arrange warehouse-in.In existing atural object mapping method, framing adopts rectangular mapsubdivision or Trapeze according to " national basic-scale topographic map framing and numbering ", there are the following problems in the mapping operation for this kind of framing mode: 1, in field operation, increase the workload that field operation is measured, for example the framing line has been crossed in house to be measured, in two width figure each some, if this two width figure is distributed to different measuring team and is repaiied side, so in order to guarantee the integrality of atural object, this house will be measured unit by two and measure respectively once; Owing to limited by framing and natural conditions, field operation is adjusted often to paint/survey and draw and is surveyed opposite bank because the map sheet cross a river turns, and the achievement of measuring by sheet also needs to cut into the framing achievement, has increased workload, also causes work inconvenience, and destroys integrality; 2, in interior industry, newly survey compilation or repair and survey compilation or reduce the staff no matter be, edge fit is all necessary operation, and the workload of edge fit is very large, take greatly the time that data are processed, and the error of edge fit process and mistake also be difficult to avoid, lost data precision that can be artificial, hinder the lifting of the quality of data.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of complete atural object mapping operational method based on subregion is provided, the method not only scope is divided the inconvenience of reasonably avoiding field operation, also allows the edge fit workload level off to zero, and has farthest safeguarded the integrality of atural object.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of complete atural object mapping operational method based on subregion, its step is as follows:
(1), atural object subregion: tested atural object is carried out to subregion, form measuring unit, take ,Fang boundary line, land deeds street, water system center line and road axis between each measuring unit is separatrix, safeguards the atural object integrality, and between adjacent measurement, corresponding sideline overlaps;
(2), field operation is measured: use GPS, total powerstation, spirit-leveling instrument to carry out control survey, measure the smashed parts, the positional information of atural object, landforms and corresponding attribute information in pickup area;
(3), interior industry is processed: by interior industry Become the picture software by the atural object of field data acquisition, the plotting on computers of landforms position, corresponding attribute information, configure corresponding line style, symbol, word annotation, be met the cartographic data of the graphic requirement of GB, complete atural object mapping operation.
And in described tested atural object, the separatrix of river, irrigation canals and ditches is arranged on the right-hand or below of water system center line.
And in described tested atural object, the separatrix of road is arranged on the right-hand or below of road axis, safeguards the atural object integrality.
Advantage of the present invention and beneficial effect are:
This complete atural object mapping operational method based on subregion is for current operating type, facilitating field operation to adjust paints/surveys and draws, industry edge fit workload in reducing, rationalization partition, farthest reduced cross a river ,Kua road operation, stop to cut the achievement data, substantially eliminated the edge fit workload, farthest safeguarded the atural object integrality.The present invention adapts to the field operation work pattern, and the edge fit workload levels off to zero, and traditional framing data edge fit workload accounts for 1% to 3% of view picture figure workload and do not wait, and effectively safeguards the integrality of atural object, is applicable to data management.
The accompanying drawing explanation
Fig. 1 is the tested atural object subregion of the present invention schematic diagram.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of complete atural object mapping operational method based on subregion, its step is as follows:
(1), atural object subregion: tested atural object is carried out to subregion, form measuring unit, ,Fang boundary line, land deeds street, water system center line and road axis take between each measuring unit as separatrix 1, safeguard the atural object integrality, between adjacent measurement, corresponding sideline overlaps, in tested atural object, the separatrix of river, irrigation canals and ditches is arranged on the right-hand or below of water system center line, and in tested atural object, the separatrix of road is arranged on the right-hand or below of road axis, safeguards the atural object integrality;
(2), field operation is measured: use GPS, total powerstation, spirit-leveling instrument to carry out control survey, measure the smashed parts, the positional information of atural object, landforms and corresponding attribute information in pickup area;
(3), interior industry is processed: by interior industry Become the picture software by the atural object of field data acquisition, the plotting on computers of landforms position, corresponding attribute information, configure corresponding line style, symbol, word annotation, be met the cartographic data of the graphic requirement of GB, complete atural object mapping operation.
The administrative division boundary line be take as main reference line in measuring unit of the present invention separatrix, in conjunction with situation on the spot, in principle the following rank administrative boundary in district is made the appropriate adjustments, district and above rank administrative boundary must not be adjusted in principle, can the adjusting as one sees fit of the important atural objects such as gland house.When in the present invention, the linear ground objects such as railway, line of electric force are inevitably cut in the measuring unit separatrix, should suitably adjust the boundary line crosscut, be convenient to edge fit.Measuring unit is divided the integrality that should suitably take into account the important areas such as important commercial street, cultural street, and measuring unit is of moderate size, and take 1:2000 as example, comprises 10 to 30 width standard framings and is advisable.
