Relevant algorithm introduction:
Overlap Analysis: Overlap Analysis is one of the conventional means that GIS-Geographic Information System extracts space implicit information.It is looked into position
It askes different, new figure layer is produced by Overlap Analysis, and the partial element for inputting figure layer can be applied the boundary of figure layer and divide
It cuts.The new data figure layer that Overlap Analysis generates combines all properties of original two or more figure layer elements, not only generates
New spatial relationship, and the relation on attributes of All Layers is updated.VectorLayer Overlap Analysis mainly includes being stacked
Ask friendship, stacked summation, difference except stacked, identity are stacked and update stacked.
Identity Overlap Analysis is exactly to carry out polygon overlapping, and output figure layer is to retain using wherein one input figure layer as control
All polygons within boundary.The process of identity Overlap Analysis operation is to input figure layer for control boundary, to its boundary
Element in addition is deleted, and the element within its boundary is retained, while it is folded to have carried out polygon to the element within boundary
Closing operation.
Buffer zone analysis: buffer zone analysis refers to based on point, line, surface entity, establishes one fixed width around it automatically
Then buffer area polygon figure layer in range establishes being superimposed for the figure layer and target figure layer, is analyzed and obtain required knot
Fruit.It is one of the spatial analysis tool for solving the problems, such as proximity.Proximity describes two ground object distances in geographical space
From similar degree.
Buffer zone analysis is important one of the spatial analysis functions of GIS-Geographic Information System, it is in traffic, forestry, resource pipe
Reason has a wide range of applications in urban planning, such as the demarcation of the protection zone around lake and river, the choosing in automobile services area
It selects, the foundation of buffer area of the private residence area far from street network etc..
Analysis of spatial relations: should also possess between geometric object other than it can carry out various topological analysis, between them
Certain attribute of a relation, such as comprising, intersection, superposition and in inside two can be obtained by the spatial relationship operation between geometric object
Relationship between a geometric object, has something to do operation require geometric object dimension having the same, some are but without this limitation.
Inclusion relation analysis in space is for detecting the inclusion relation of two geometric objects, if geometric object A includes geometry
Object B, then geometric object B is just in the inside of geometric object A.In inclusion relation, the dimension of geometric object B be necessarily equal to or
Lower than the dimension of geometric object A.
The symbol definition for judging to use relevant to tolerance are as follows: ARC is area tolerance, and CRC is length allowance；GB is background
The GB code of data, GB_ are the GB code of more new data；PIArea.Area be based on identity Overlap Analysis technical treatment after
The area of planar data, pIArea.Area_ are the area based on shape data behind reversed identity Overlap Analysis technical treatment；
Shape_Area is monitoring planar data surface product, and Shape_Ar_1 is background planar data area；PIPolyline.Length is
Based on the length of data linear after identity Overlap Analysis technical treatment, pIPolyline.Length_ is based on reversed identity
The length of linear data after Overlap Analysis technical treatment；Shape_Leng1 is to monitor linear data length, and Shape_Le_1 is this
Baseline shape data length.
