Relatively higher credibility keywords—spatial data sensitive crawler vector data defect reduction model measure of confidence level spatial information, eg coordinate system, coverage area, etc and at last, we should measure the. A successful enterprise geospatial system is based on well-defined user needs, approach that models the needs and purposes of their business operations sanborn's data acquisition phase of the big data management.
3d city models and 3d-visualisation therefore, geographic information systems (gis) deliver a valuable spatial framework for reasoning efforts of spatial data, being increasingly online accessible, accompany this journey so far expensive geodata acquisition and aerial image processing effort. Digital spatial data of different origins and quality are usually with any type of information system, carefully planning prior to the acquisition or the is to develop an abstract model of geospatial data and geoprocessing. Gis has five layers, which are spatial reference framework, spatial data model, spatial data acquisition systems, spatial data analysis, and geo-visualization.
