GIS: GIS-Geographic Information System (Geographic Information System) is a kind of computer based work
Tool, it can be analyzed and be handled to spatial information.GIS technology is this unique visualization effect of map and geoanalysis
Function is integrated with general database manipulation (such as inquiry and statistical analysis etc.).
ArcGIS: being the GIS-Geographic Information System groupware produced by ESRI, wherein ArcMap (is most basic answer
With program assembly, charted, edited, map space analysis, but being primarily used to the processing space 2D map) ArcCatalog
(being used to management space data, carry out the Simple Design of database and be used to record, show attribute data metadata)
GIS map service: Map Services are a kind of methods for making map that can access by Web using ArcGIS.It is logical
Map Services are crossed, map, element and attribute data can use in a plurality of types of client applications.
ArcGIS API for JavaScript:ArcG for JavaScript development interface.
ArcGISTiledMapServiceLayer:
Esri/layers/ArcGISTiledMapServiceLayer can be loaded directly into the caching map of server end
Service.
QueryTask: querying attributes obtain data item quantity (esri/tasks/QueryTask).
Geometry Service: by calling geometry service to carry out seeking friendship analysis (esri/tasks/
GeometryService)。
IRelationalOperator: for determining existing spatial relationship between two figures, spatial relationship type packet
Include include, intersect, is equal, connecting, is non-intersecting, overlapping, inside etc..
Overlay Analysis: overlay analysis is a very important spatial analysis functions in GIS.Refer to and is uniting
Under one spatial reference systems, by a series of set operations carried out to two data, the process of new data is generated.
Inersect Analysis: asking friendship analysis to come out the extracting section that spatial relationship can intersect in two figure layers,
It is individually created a figure layer, which gathers around the attribute there are two figure layer simultaneously.
Specifically, to solve problem of the prior art, the present invention provides a kind of automatic Verification side of pipeline vector data
