"Topology" refers to the relativity of spatial data, used to express the spatial relationships between the locations and features in space. With SuperGIS Topology Analyst, users can generate the topology for spatial files without topology by means of Clean and Build processes, which can be used as a basis for later analyses.

• Supports the use of Clean to process data before conducting topology analysis.
• Build process is supported for generating topology.
• Topology results can be exported to:
  

  	SFA (SuperGeo Feature Archives) file format: saves features of point, polyline,
  	and polygon at once and records spatial relationships between features.
  	GEO and Shapefile formats: do not record spatial relationship between features.

• During the Clean process, users can set up a Fuzzy Tolerance parameter.
• During the Clean process, users can set up a Dangle Length parameter.
• With the Data Conversion function, users can convert the features stored in the SFA topology data to Polygon, Polygon Label Point, Polyline and Node vector files in *.geo or *.shp format.
• Tools for polygon label point:

  	Enable users to build a Polygon Label Point data from the SFA file to a point
  	layer in GEO or Shapefile format.
  	Enable users to calculate the polygon layers in GEO or Shapefile format to
  	obtain a Polygon Label Point data and export the result as a point layer.

• Attribute tools:

  	Enable users to assign related fields to join the attribute tables of SFA
  	topology data or Polygon attributes of vector files in GEO or Shapefile format.
  	Enable users to assign related fields to join the attribute tables of SFA topology
  	data or Polyline attributes of vector files in GEO or Shapefile format.

Support File Formats

• Vector files in GEO (SuperGeo GEO Format) and Shapefile formats are supported.
