#21323 new defect

KML: when nodes have same coordinates, only 1 is imported

Reported by: tguen Owned by: Don-vip
Priority: major Milestone:
Component: Plugin opendata Version:
Keywords: kml Cc: tguen

Description

I got a set of address data from a county government. Some taxlots have multiple addresses, which are represented by multiple tagged nodes on the taxlot with the exact same coordinates. When importing this data into JOSM as a .kml file, only one node at each set of coordinates is imported. This results in thousands of addresses being lost. This issue does not occur with .shp files.

What steps will reproduce the problem?

  1. Install opendata plugin
  2. Import a .kml file with multiple tagged nodes at the same location.

What is the expected result?

All nodes should be imported

What happens instead?

Only one node is imported at any point

Please provide any additional information below. Attach a screenshot if possible.

Similarly, when importing GeoJSON, nodes with identical coordinates are inappropriately merged.
