Good Day QGIS Users!
I am working on a GIS project where my area of interest (drainage basin and
river network) cover two UTM Zones. In this case, I cannot use UTM to
compute for area and distance, and to perform other analysis in which
spatial data needs to be projected. What projection can I use? Is Equal
Area Cylindrical NSIDC EASE - Grid Global (EPSG: 3410) okay to use if
working on a very large spatial dataset? Is this widely used by GIS users?
I just made a regular vector grid in this projection, and found that the
y segments get smaller towards the poles. So it is not suitable for
distance measurement. I would suppose to create a transveres mercator
projection around the middle axis (+lon_0) of your area (if there isn't
any yet).
Greetings,
André Joost
