Issue exporting Occurrence contours #125

Closed P-Reynolds closed 3 years ago

P-Reynolds commented 3 years ago

Hello,

I've come across an issue where all my occurrence distribution exports end up being the 95% contour level once exported. Though, I was able to export 50,75,and 95% contours for my home ranges successfully. The 50% contours plots for OD will load and look fine in the ctmmweb app but once I export them into ArcGIS they are always the 95% contour? Even the attribute table for the shapefile has only one row of information and says its the 95% est contour.

I've tried on multiple different devices with the latest update of the web app. How can I export and download the 50% (or anything other than 95%) for my occurrence distributions? Sidenote: the grd format exports come up as invalid datasets when I try to import them into ArcGIS, however the TIFF format works correctly.

Thanks for any advice. Patrick

Thanks for the report. There is a missed parameter in the export and I'll fix the bug.

@P-Reynolds , can you try with this version?

remotes::install_github("ctmm-initiative/ctmmweb", ref = "daily")

xhdong-umd commented 3 years ago

@chfleming , one question about exporting to raster. ctmm::writeRaster will not take level.UD parameter, because raster export doesn't show the contours, right? I wanted to note this in help but want to confirm first.

chfleming commented 3 years ago

That's correct.

P-Reynolds commented 3 years ago

Thank you, the new version seems to cleared up the problem! ArcGIS still won't accept the .grd raster formats I export saying it is an invalid dataset, not sure if it is just a problem on my end but the TIFF exports upload fine if I need the rasters, so no other problems from me.

Thanks for the help.

@P-Reynolds , .grd is a R raster package native format, you will need to convert it first before importing into ArcGIS. See ?raster::writeRaster and this guide Exporting Rasters from R to ArcGIS.

Thanks for the clarification.
