Cellarea crashes Julia on engineering crs

[evetion]

using Rasters, Proj, ArchGDAL
r = Raster("https://github.com/Deltares/Geomorphometry.jl/releases/download/v0.6.0/saba.tif")
cellarea(r)

Can confirm...that seems bad

[asinghvi17]

cellarea(Planar(), r) works as expected. The problem is that this CRS has no geographic CRS backing it and so there is no way to go to lat/long. We need to detect that in the main function and dispatch...

Probably has to be Proj or GDAL to kill Julia?

[asinghvi17]

Yes the stacktrace points to Proj

This must be a Proj issue, right? Seems like it segfaults if it can't do a conversion and always_xy = true.

using Rasters, Proj, ArchGDAL
r = Raster("https://github.com/Deltares/Geomorphometry.jl/releases/download/v0.6.0/saba.tif"; lazy = true)

transform = Proj.Transformation(crs(r), EPSG(4326)) # errors
transform = Proj.Transformation(crs(r), EPSG(4326); always_xy = true) # segfaults

But also this CRS seems to be invalid? ArchGDAL.importCRS(crs(r)) gives ERROR: Failed to export this SRS to PROJ.4 format (Failure.)

[evetion]

It's a local engineering CRS. Should be valid, but you can't transform it. It should error though, not crash, and not sure if that's a bug at the Julia side of Rasters, Proj or PROJ itself.

[rafaqz]

It's pretty hard for Rasters to cause a segfault, and really Proj should protect other packages from this

[tiemvanderdeure]

I made an issue in Proj, think it should be handled there

Closing as not a Rasters.jl issue
