Description
Technical field
The irregular small-sized Land area measure method based on photoelectric measurement technology that the present invention relates to a kind of.
Background technique
Making rational planning for and utilizing to rural holding is the important step for developing China's agricultural economy.Therefore soil is provided
The arrangement in source first has to since Land area measure, and GPS area measurement instrument is realized based on GPS technology to farmland soil ground
Long-pending measurement and record provides help for agricultural production and Land planning utilization.Investigate thoroughly quantity, the distribution of land resource
And utilization obstacle, and the evaluation of science is given using structure to it, it is farming region for preferably rational exploitation and utilization land resource
It draws and land use planning provides scientific basis, just become a highly important task.In the past few years we are to 20 counties Duo Ge
City's clay detailed Investigation staff's training, and clay detailed Investigation checking and accepting has been participated in, it is theoretical to encounter many related area measurings
The problem of in terms of method.Herein for each county's existence conditions and technical level, in the essence and area measuring with regard to Sha Weiqifa
Simple calculation formula is discussed, is referred to for the parties concerned.Area is measured on figure, by map scale precision, mapping with
Influence of the precision of making picture to spirogram: the influence of distortions of a map projection, cartographic generaliztion: the influence of drawing deformation: land type boundary line
Adjust the influence drawn with rendition precision: and the influence of the factors such as spirogram instrument and operating method.The bigger then precision of map scale
Higher this is well-known.The measurement of land type area, the topographic map using l:1 ten thousand are ideal.1:5 ten thousand can't be used
Figure zoom into ten thousand amount of the progress calculation of the side 1:l or 1:2.5.Do not reach not only like that and propose high-precision effect, instead due to amplification
When theoretical size control inaccuracy, or blueprint reasons such as paper distortion cause the figure of ratio of precision l:5 ten thousand to decrease.China
Projection used by topographic map is gauss projection, and each belt edge part maximum of area distortion is no more than 1/500.So it is right
The precision that land area measures influences less, can be not significant.But paper distortion is affected to measuring area, deformation system
Number is in 1 strong 00-1/l00, and deformation is unevenly distributed.Type, the mode of preservation, temperature of the size of paper distortion by drawing
Depending on the factors such as degree, humidity.When folding such as drawing, splice, rub volume, damp and hot weather, deform just more significant.So
Its influence should be reduced when spirogram as far as possible.As for the selection and method of measuring instrument, in county land measuring area, by condition
It is limited with technical level, planimeter cooperation square method is mostly used to carry out.According to State owned land detailed survey " regulation ", area measuring is necessary
Then measuring area with planimeter in accordance with the taste of " controlling layer by layer, classification amount is calculated, in proportion adjustment " generally can reach relative accuracy 1/
400.When reference area, if pole is placed in outside figure, the planimeter of precision qualification in application Sha Weiqifa reference area, then without
Demand c value.
