Geographic Information Systems Asked on December 12, 2020
I have a point layer in QGIS in EPSG:4326 and want to create polygon-circles of 10m radius around each point. All of the points are located within a squarekilometer in northern Germany. How do I do this? Buffering generates circles which are ellipses and way too big.
I’m quite unexperienced with GIS and I honestly searched the old questions before I posted this.
From your comment your data is in EPSG 4326 which is WGS 84, this uses latitude and longitude coordinates, so when you tell that to buffer by 10 it buffers by 10 degrees which is massive.
To get your point layer to use metres instead you will need to convert it to a CRS which uses metres. You will need to right click on the layer in the table of contents, then Export > Save Features As and as part of saving them choose an appropriate CRS. Choosing the right CRS depends on where in the world your data is. Google is your friend here to find out what's the right CRS.
This new dataset should now buffer correctly.
