I'm very new to gbd table and today at work I was asked to use R to read the data available on https://frap.fire.ca.gov/media/9792/fthrt14_2.zip and plot it using R tools like ggplot and plot_ly. My problem is that I don't even understand how to read this data with R. These are the stackoverflow questions I read so far: - rgdal - read a table within a ESRI geodatabase (gdb) - How to read a table from an ESRI file geodatabase (.gdb) using R - How do I get rgdal to open a geodatabase (.gdb) file? however none of them seems to be working. These are my steps: - I unzipped the file in my C:\temp folder. This means I have an R variable file_gdb = "C:/temp/fthrt14_2.gdb" - then, I have fc_list = ogrListLayers(file_gdb ) and if I print its content I see: 

character(0)
attr(,"driver")
[1] "OpenFileGDB"
attr(,"nlayers")
[1] 0

  • at this point I try fc = readOGR(dsn=fgdb,layer="OpenFileGDB") but I get the following error:

    Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv Cannot open layer

and from here I'm quite lost. Any help would be much appreciated. Many thanks from a complete newbie.

  • That a zip file. It does have severak gdb files in the zip archive, but you first need to expand it and then work on them separately. – IRTFM Nov 14 '19 at 20:55
