Abstract
The invention discloses the methods that a kind of smart mobile phone/tablet measures national territorial area.In area to be measured, the three-dimensional space position information of its boundary point is gathered by mobile phone/tablet, longitude (B), latitude (L), height above sea level (H), utilize the method for GPS difference, it is accurate to resolve national territorial area, the method is quick, efficiently, accurately determine national territorial area, improve the utilization rate of Land Information.
Description
First, technical field
The present invention relates to the method that a kind of smart mobile phone/tablet measures national territorial area, especially by two mobile phone/tablets
The three dimensional space coordinate of Measured Boundary point and the method for accurately measuring national territorial area by GPS difference.
2nd, technical background
In clay detailed Investigation or other agriculture and forestry production processes are carried out, the area for understanding a piece of land usually may require that.
At this point, often to carry out Land area measure.At present, national territorial area mapping and information acquirement still rest on Technical comparing backwardness
Stage, most area also rest on tape measuring, manually calculate, and the original measurement of manual record is horizontal.So that national territorial area
The heavy workload of measure, cycle are long.Area estimation, expensive equipment, heaviness, it is impossible to meet production practices are carried out using instrument of surveying and mapping
In quick, Accurate Determining demand.
So the measurement that national territorial area is carried out using traditional method is not only costly and it is difficult to obtain satisfied effect.
This patent is directed to the accurate measure of national territorial area, using the method for GPS difference, passes through two mobile phone/plane-table operations and writing edge
The three dimensional space coordinate of boundary's point so as to it is quick, efficiently, accurately measure national territorial area, improve the utilization rate of Land Information.
3rd, the content of the invention
In order to overcome existing method big in national territorial area measure workload, the shortcomings such as low with efficiency of high cost are of the invention
Purpose is to provide the method that a kind of smart mobile phone/tablet measures national territorial area, it overcomes disadvantages mentioned above existing for existing method.
The object of the present invention is achieved like this：
In area to be measured, the three-dimensional space position information of its boundary point, longitude (B), latitude are gathered by mobile phone/tablet
(L), height above sea level (H) resolves the area in area to be measured, is as follows：
(1) first, the opening in area to be measured fixes A mobile phones/tablet, and B mobile phones/tablet is as mobile terminal, clockwise
Direction measures and records successively the geographical coordinate (B of each boundary pointj, Lj, Hj), wherein, j=1,2 ..., n, in B mobile phone for measuring
Meanwhile A mobile phones measure in its fixed position and record one group of (Bi, Li, Hi) data, wherein, i=1,2 ..., n utilize digital-to-analogueCalculate the average value (B of A mobile phones position geographical coordinateo, Lo, Ho).Utilize digital-to-analogue Difference Calculation is carried out, respectively obtains the correction Δ B of each boundary point longitude, latitude, height above sea levelt、ΔLt、Δ
Ht, wherein, t=1,2 ..., n.Utilize digital-to-analogueCalculate the coordinate (B of differentiated each boundary pointt, Lt,
Ht), wherein, t=1,2 ..., n；
(2) geographical coordinate (B of the differentiated each boundary point in area to be measured will be carried outt, Lt, Ht) be converted under Gauss projection plane
3 d space coordinate (the X of 2000 coordinate systemst, Yt, Zt), wherein, t=1,2 ..., n utilize digital-to-analogue The national territorial area in area to be measured is calculated, wherein, Xi+1=Xi, Yi+1=Yi。
This invention has the following advantages compared with the conventional method：
(1) this method only needs two mobile phone/tablets that can measure area, reduces manpower and materials, improves work efficiency；
(2) Quick Acquisition location information, using GPS differential techniques, fast and accurate acquisition national territorial area information.
4th, specific embodiment：
The method that a kind of smart mobile phone/tablet measures national territorial area, is characterized in particular in：
(1) first, the opening in area to be measured fixes A mobile phones/tablet, and B mobile phones/tablet is as mobile terminal, clockwise
Direction measures and records successively the geographical coordinate (B of each boundary pointj, Lj, Hj), wherein, j=1,2 ..., n, in B mobile phone for measuring
Meanwhile A mobile phones measure in its fixed position and record one group of (Bi, Li, Hi) data, wherein, i=1,2 ..., n；
(2) digital-to-analogue is utilizedCalculate the average value (B of A mobile phones position geographical coordinateo, Lo,
Ho).Utilize digital-to-analogueDifference Calculation is carried out, respectively obtains the correction of each boundary point longitude, latitude, height above sea level
Number Δ Bt、ΔLt、ΔHt, wherein, t=1,2 ..., n.Utilize digital-to-analogueCalculate differentiated each boundary point
Coordinate (Bt, Lt, Ht), wherein, t=1,2 ..., n；
(3) geographical coordinate (B of the differentiated each boundary point in area to be measured will be carried outt, Lt, Ht) be converted under Gauss projection plane
3 d space coordinate (the X of 2000 coordinate systemst, Yt, Zt), wherein, t=1,2 ..., n utilize digital-to-analogue The national territorial area in area to be measured is calculated, wherein, Xi+1=Xi, Yi+1=Yi。
