I have a polygon which the edge is quite normal when zoomed out: enter image description here

But when zoomed in this is how the edge looks like (jagged) because it was converted pixel by pixel from a raster, is there a generalization tool that can make it less jagged?

I am using ArcGIS Desktop.

  • If you need a QGIS solution too then please ask that as a separate question and let us know what you have tried within that software.

    If you created this dataset using the raster to polygon tool simply tick on the simplify option that will smooth the edge.

In ArcGIS you can try tool Integrate:

Integrate is used to maintain the integrity of shared feature boundaries by making features coincident if they fall within the specified x,y tolerance. Features that fall within the specified x,y tolerance are considered identical or coincident.

Before running the tool backup your data:

Caution: This tool modifies the input data. See Tools with no outputs for more information and strategies to avoid undesired data changes.

  • Exactly what I am looking for. Any chance that there is similar tool in QGIS? Jan 25, 2017 at 21:12
  • @chenghopan If you need to know about QGIS too then please ask a new question.
