Abstract
The present invention relates to a kind of complete atural object mapping operational method based on subregion, comprise (1), atural object subregion: tested atural object is carried out subregion, form measuring unit, between each measuring unit with land deeds street, boundary line, mill, water system center line and road axis for separatrix, safeguard atural object integrality, between adjacent measurement, corresponding sideline overlaps; (2), field operation is measured; (3), interior industry process.For current operating type, facilitate fieldwork measurement/mapping, industry edge fit workload in reducing, rationalization partition, farthest decreases cross a river, across road operation, has stopped to cut performance data, essentially eliminate edge fit workload, farthest maintain atural object integrality.The present invention adapts to field operation work pattern, and edge fit workload levels off to zero, and traditional framing data edge fit workload does not account for 1% to 3% of view picture figure workload not etc., effectively safeguards the integrality of atural object, is applicable to data management.
Description
Technical field
The invention belongs to mapping field of operation, especially a kind of complete atural object mapping operational method based on subregion.
Background technology
At present, China's base surveying work pattern can be summarized as substantially: measure/repair survey-interior industry process-arrangement warehouse-in by map sheet field operation.In existing atural object mapping method, framing adopts rectangular mapsubdivision or Trapeze according to " national fundamental GIS framing and numbering ", there are the following problems in mapping operation for this kind of framing mode: 1, in field operation, increase the workload that field operation is measured, such as house to be measured spans framing line, in two width figure each some, carry out repairing side if this two width figure is distributed to different measuring team, so in order to ensure the integrality of atural object, this house will be measured unit by two and measure respectively once; Owing to limiting by framing and natural conditions, normal the turning because of map sheet cross a river of fieldwork measurement/mapping surveys opposite bank, and the achievement measured by sheet also needs to cut into framing achievement, adds workload, also causes work inconvenience, and destroys integrality; 2, in interior industry, no matter be newly survey compilation or repair survey compilation or reduce the staff, edge fit is all necessary operation, and the workload of edge fit is very large, take the time of data processing greatly, and the error of edge fit process and mistake are also difficult to avoid, lost data precision that can be artificial, hinders 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 divides the inconvenience of reasonably avoiding field operation, also allows edge fit workload level off to zero, and farthest maintains the integrality of atural object.
The present invention solves its technical matters and is achieved through the following technical solutions:
Based on a complete atural object mapping operational method for subregion, its step is as follows:
, atural object subregion: tested atural object is carried out subregion, forms measuring unit, between each measuring unit with land deeds street, boundary line, mill, water system center line and road axis for separatrix, safeguard atural object integrality, between adjacent measurement, corresponding sideline overlaps;
(2), field operation measures: use GPS, total powerstation, spirit-leveling instrument 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 process: 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 the separatrix of river, irrigation canals and ditches is arranged on right or the below of water system center line in described tested atural object.
And in described tested atural object, the separatrix of road is arranged on right or the below of road axis, safeguards 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, facilitate fieldwork measurement/mapping, industry edge fit workload in reducing, rationalization partition, farthest decrease cross a river, across road operation, stop to cut performance data, essentially eliminated edge fit workload, farthest maintained atural object integrality.The present invention adapts to field operation work pattern, and edge fit workload levels off to zero, and traditional framing data edge fit workload does not account for 1% to 3% of view picture figure workload not etc., effectively safeguards the integrality of atural object, is applicable to data management.
Accompanying drawing explanation
Fig. 1 is the present invention's tested atural object subregion 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.
Based on a complete atural object mapping operational method for subregion, its step is as follows:
(1), atural object subregion: tested atural object is carried out subregion, form measuring unit, between each measuring unit with land deeds street, boundary line, mill, water system center line and road axis for separatrix 1, safeguard atural object integrality, between adjacent measurement, corresponding sideline overlaps, in tested atural object, the separatrix of river, irrigation canals and ditches is arranged on right or the below of water system center line, and in tested atural object, the separatrix of road is arranged on right or the below of road axis, safeguards atural object integrality;
(2), field operation measures: use GPS, total powerstation, spirit-leveling instrument 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 process: 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.
Measuring unit separatrix of the present invention with administrative division boundary line for Primary Reference line, in conjunction with situation on the spot, make the appropriate adjustments the following rank administrative boundary in district in principle, district and above rank administrative boundary must not adjust in principle, can adjusting as one sees fit of the important atural objects such as gland house.When the linear ground object such as railway, line of electric force is inevitably cut in measuring unit separatrix in the present invention, should suitably adjust boundary line crosscut, be convenient to edge fit.Measuring unit divides the integrality suitably should taking into account the important areas such as important commercial street, cultural street, and measuring unit is of moderate size, and for 1:2000, comprises 10 to 30 width Standard division range and is advisable.
