I have several Feflow files that are displayed as points in QGIS. I would like to display points that have the same value scale as a polygon (F Value in the attribute table). Is this possible?

Is there no function like point to polygon? (Like select all points with the same value and form a polygon) I have already tried

  • Theisen Polygon (this seems quite wrong to me)
  • Convert point to polygon

It is also possible to save the Feflow file as a shapefile with polygons. Then the polygon contains single triangles. Here is the problem at the end, the file size.

Could I possibly convert the individual triangles to a surface?

Attribute Table of the point shapefile

Shapefile with the triangles

Dissolve will work using your polygon shapefile with the triangles if you select "F" in the dissolve field

  • Also if you expect distinct polygons with the same F value they will be part of the same MultiPolygon. If you would prefer them to be separate polygons you can use "Multipart to singleparts" processing tool to do so
