I have a KML style file provided of burnt areas from significant wildfires. As the fires continue, seven of the polygons out of about 30 appear to be corrupted with duplicate nodes and overlapping areas from repetitive updating.
I have been using grass v.clean and validate geometry which has been successful however that has stopped working on a windows 3.4.4 install and I am at a loss of how to import this successfully.
Can anyone recommend a way to fix the file within QGIS?
The file is available here
