Clean Contour Gaps
Open Table of Contents ToolBox Implementation

Cleans the gaps in a polyline dataset representing contours.

Inputs:

  • A Polyline dataset
  • A field representing the elevation value of the contours
  • Tolerance - the gaps smaller than this tolerance will be closed.

Outputs:

  • New polyline feature class. The gaps in the contours that a smaller than the selected tolerance are closed.

Notes: 

  • The function is designed specifically for contours, but it can be used on datasets representing different features.
  • Always inspect the results before accepting them as valid.

Example :
