Evaluation.
Detailed description of the invention
Fig. 1 is work flow diagram of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of mapping method of reallocation of land regulation project, the soil
Specific step is as follows for the mapping method of ground planning and restoration project:
S1: analyzing the analysis of foundation engineering geologic elements and unfavorable geology and special geology, specifies form between each element, sky
Between distribution, the origin cause of formation, correlation and the influence to route, foundation engineering geologic elements include topography and geomorphology, bottom lithology,
Geological structure and hydrogeological element；
S2: determining enginering geologic sections principle, treats mapping region and carries out enginering geologic sections and SUBNUCLEAR DIVISION, according to research
The characteristics of surveying and drawing area determines Evaluation of Engineering Geological Conditions standard, carries out integration engineering geological conditions superior and inferior evaluating to each region；
S3: region to be surveyed and drawn is carried out by section division according to the otherness of evaluation result, the comparison for two or more
Route synthesis in terms of landforms, lithology, construction, hydrogeology, unfavorable geology, special geology, line length, ecological environment is commented
Valence engineering geological condition superiority and inferiority provides sufficient foundation for final scheme；
S4: using atural object, the geomorphology information in GPS, hydrology instrument, total station acquisition mapping region, by measurement adjustment method to survey
It draws data to be handled, and the data of acquisition is imported in coordinate system, visualization three is carried out on three-dimensional visualization software platform
Dimension is shown, carries out data processing, specific step using measurement adjustment method for surveying and mapping data are as follows:
S41: according to the specific data column condition equation of Surveying and Mapping Project；
S42: composition normal equation, AQATK+W=0；
S43: solution normal equation asks connection COEFFICIENT K, K=- (AQAT) -1W；
S44: correction V, V=P-1ATK=QATK are asked；
S45: seeking the mean difference of mapping value,
S46: core inspection is carried out to mapping mean difference；
S5: standard line style compatible with surveying and mapping data, the information of symbol, label character on three-dimensional display platform have been formed
Whole reallocation of land schema mapping.
The present invention is handled surveying and mapping data using the method for measurement adjustment, is eliminated and is respectively seen in plane or vertical control network
Geometrical condition between measured value is asked the optimum evaluation and evaluation observation element of each geometric element in fixed control net by least square method
And its work that function precision is carried out.The data of one compensating computation unit can be divided into initial data, observation data and wait ask
Data three classes.Observation data include known high-precision elongated, azimuth, elevation etc., and observation data include horizontal direction, become
Length, height difference etc., data to be asked include the coordinate of unknown point, elevation etc..Initial data and data to be asked are non-random datas, and
Observing data is random data, and containing error, error can be divided into systematic error and accidental error.
The influence attenuation method of systematic error can carry out observation data by using being adjusted and examining and determine to instrument
Design allows same people to observe whole observations and observes habit variation bring systematic error and progress to avoid substitution bring
Atmosphere Refraction and correction for earth curvature etc.；Accidental error all shows contingency in size and symbol, but accidentally misses from a large amount of
The totality of difference sees that it is normal distribution, least square method aiming at accidental error processing method, in practical work process
In, in order to improve the quality of achievement, and also to check and find that whether there is or not rough error presence in observation, will usually carry out in time
Redundant observation.It due to the presence of accidental error, can find that observed result is inconsistent by redundant observation, or not meet and should have relationship
And the contradiction generated.Therefore, it is necessary to adjustment processing be carried out to these observations with accidental error, so that after eliminating discrepancy
Result be considered the reliable results of observed quantity.
According to mathematical statistics, a certain observing buoy is the increment seeing all possible values (parent) to this and being extracted, son
Sample and parent have identical probability distribution, can use increment and judge to the statistical property of parent, but due to limited
Several observations can only obtain the estimated value of observation, and cannot obtain its true value, therefore the present invention is according to the accidental mistake having
Difference limited observation come determine parameter optimum evaluation and assess observing buoy quality.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
