I am new to QGIS and I want to create Iso-areas using the "Iso-Area as Interpolation (from Layer)" tool from the QNEAT3 Plugin to visualize areas dependent on the distance to a layer. I used various projected coordinate systems such as EPSG:3857 or EPSG:32700, however, I still always receive the following error code:
The TIN-Interpolation algorithm in QGIS is designed to work with projected coordinate systems. Please use a projected coordinate system (eg. UTM zones) instead of geographic coordinate systems (eg. WGS84)!
Also already found this post: Changing shapefiles from geographic (WGS84) to projected (EPSG:2263) coordinate system using QGIS addressing the same problem, however I still don't get it solved.
