I have several KMZ files that i want to import into QGIS, when i import any one it contains many features with different geometries and i only need the points one

the problem is when i try to merge them using mmqgis it says that i cant merge those layers saying that (points != 2.5d points) ,so:

1) is there a way to merge all those points without losing the data?

2) is there a way to detect the (2.5d points) and separate them so i can normally merge all the other points and i would manually add those points myself?

  • What is 2.5d points, and what data that points contain?

  • not sure what is 2.5d points, but when i try to merge all the layers in mmqgis it say that it cant merge 'points' and '2.5d points'..so i assume they're considered as different features

  • 2.5d points have a Z value for elevation. You can only merge features which have the same geometry type. There is a conversion function in mmqgis which you should be able to use to convert your 2.5d points to points. You should then be able to perform the merge.

You want to convert the KMZ to SHP. When you open the KMZ layer in QGIS, layers appears on the Layer's Panel. With a right clic on it, you can SAVE AS and define Shape file.
