Thin (Generalize) Points

Not available in the versions of ET GeoWizards for ArcGIS 8.x

Reduces the number of points in a point dataset based on their spatial location.

• Points that are closer to each other than the tolerance specified will be converted to a single point.
• The values in the field specified will be summarized for each cluster and saved in the point representing this cluster.

Inputs:

• A Point feature class
• Generalization tolerance - should be smaller than 20% of the smaller side of the extent envelope of the input dataset.
• Data field - if specified the output feature class will have a field in which the value for each resulting point will be the sum of the values of the points pertaining to this cluster.

Outputs:

• New point feature class. Fields:
  • [ET_Count] - the number of points from the input feature class represented by each output point
  • Value Field - the sum of the values in the user specified field

Notes:

• If no Generalization tolerance is specified, the tolerance will be set to 0 - only the exact duplicates will be removed
