I want to close gaps between polygons that are not intersecting and without a barrier in between (like streets). Its possible by "Aggregate Polygons", but this tool is dissovling all intersecting polygons and the one within a distance.

Is it possible to aggregate or connect neighboring polygons (or closing the gaps between) within 1 m and in the same time without dissolving directly adjacent ones?

It is important that edges remain at not relevant polygons.

    Have you tried the snap tools in the toolboxes of ArcGIS or QGIS? The 1m would be your tolerance setting.

  • Should the buildings move, or expand to fill the gaps?

  • Expand, not relevant edges should remain!

  • Snap can solve it somehow. But small structures within a polygon get changed as well. But as a first result, I can work with it! Thanks

Try Integrate, but backup your data first because the tool will modify it.

Analyzes the coordinate locations of feature vertices among features in one or more feature classes. Those that fall within a specified distance of one another are assumed to represent the same location and are assigned a common coordinate value

Then Dissolve if you want to dissolve the borders.

  • It would connect polygons indeed, but there is no chance to add a barrier feature. So polygons would get connected without any consideration of lines.

  • Can you add a screenshot showing your data?

  • Additionally, if I set a threshold of 50 cm in the Intregate Tool, it still connects nodes, which have a distance of 1,20 m, and i dont know why.
