When polygons are converted to points, the new point features are attributed in the following manner: The point feature is automatically populated with the polygon's values for all common attributes. Any attributes that are only in the point feature class are populated using the point fe...
Polygons can be created from points to determine the distribution pattern of point features. For example, creating soil maps based on irregular point samplings of soil types, simulating the cellular c
Polygons are the preferred geometry type for reference data that represents administrative areas, postal codes, and points of interest, because they provide more accurate reverse geocoding results and allow the Create Locator tool to restore missing attributes through spatial linking in multirole ...
If thePreserve attributesoption on the dialog box is checked (theattributesparameter is set toATTRIBUTESin scripting), the output attributes schema and field values will depend on whether the label features (points) are provided in the following ways: ...
Create points representing the highest or lowest elevations within polygon features Procedure The three general steps of the procedure are to identify the maximum elevation values within each polygon, identify which specific cells in the DEM correspond to the maximum values, and then convert those ...

@g6 isn't valid because the ring doesn't have at least three distinct points.Orientation of spatial dataThe ring orientation of a polygon isn't an important factor in the planar system. The OGC Simple Features for SQL Specification doesn't dictate a ring ordering, and SQL Server doesn't ...
The use of points for mapping PPGIS attributes and aggregating areas through density mapping constitutes a conservative approach to spatial inference about place significance, but the data demands for point collection are considerably higher than for polygon features. Based on our results, we provide ...
For example, you can load a set of collected points from a global positioning system (GPS) unit into ArcGIS and use this tool to create polyline or polygon features from those points. Ideally, the points would be loaded with associated waypoint IDs that can be used to determine ...
