Hence the value in a cell of the new system can end up being some average of whichever grid cells in the source raster it overlapped. If you have a raster and points ...

Following on Ian Turton's comment... Prior to performing ANY geometry calculations or analysis on a layer(s), the layer(s) MUST be 1) projected to the desired CRS, and 2) that CRS must be the same for all layers. (Sidenote #1: in QGIS, projecting a layer to a different CRS is typically accomplished using Save As...) Your analysis will always fail if the ...

Custom crs are stored is a sqlite database table tbl_srs. The database itself is under your profile path and the file is called qgis.db. So, it should be safe to delete the rows of the table. To do that, close QGIS, make a copy of that db-file (if something goes wrong...), and open qgis.db in a sqlite-database sql-monitor, like spatialite-gui or ...

Lambert equal-area projection laea_centered <- "+proj=laea +lat_0=-70.30744 +lon_0=43.15268" call me crazy, but don't you have the lat and long switched around?

The issue you are running into is a pyproj 1x issue. I would recommend installing pyproj 2+. You can do this with conda using the conda-forge channel: conda config --add channels conda-forge conda config --add channels conda-forge conda config --set channel_priority strict conda create -n geo geopandas conda activate geo Or, you can install the latest ...
