How To: Delete duplicate points from a point coverage

Summary

Steps to delete points with identical X,Y coordinates.

Procedure

  1. The THIESSEN command creates a new polygon coverage that has a polygon around each set of duplicate points.

    Code:
    Usage: THIESSEN <in_cover> <out_cover> {proximal_tolerance}
    Arc: thiessen sample outlinecov

  2. In ArcEdit, set the EDITCOVERAGE to the point coverage and the EDITFEATURE to arcs.

    Code:
    Arc: arcedit
    Arcedit: editcoverage sample arcs

  3. Use GET to copy the arcs from the polygon coverage.

    Code:
    Arcedit: get outlinecov

  4. CLEAN the coverage with the NODUPS and NODIFFS options to eliminate the duplicate labels in each polygon.

    Code:
    Usage: CLEAN {DEFAULT | fuzzy_tolerance | *} {DEFAULT | dangle | *}
    {DUPSOK | NODUPS} {DIFFSOK | NODIFFS}
    Arcedit: clean nodups nodiffs

  5. Change EDITFEATURE to label, select all the labels and PUT them to a new coverage.

    Code:
    Arcedit: editfeature label
    Arcedit: select all
    Arcedit: put finalcov

  6. In Arc, BUILD point topology for the new coverage.

    Code:
    Arc: build finalcov point
