get_ssurgo only downloading first item in list for template

[kross0926]

When using get_ssurgo() and supplying a vector of area names the tool is only downloading one of the items. Oddly enough in the example code its the second item. This is happening with both my code and the code in the example:

SSURGO.areas <- get_ssurgo(template=c('CO670','CO075'), label='CO_TEST')

I've also tried supplying a spatial object to extract the databases but I get his error...which I was assuming is because my download area is too large? (the polygon is 39 HUC 12 boundaries so its likely this is could be the case)

Error in { :
task 2 failed - "trying to get slot "data" from an object of a basic class ("NULL") with no slots"

Hi here. Thanks for catching this... I just pushed a change that should fix the multi-area problem, though you'll have to install the development version:

#install.packages("devtools")
devtools::install_github("ropensci/FedData")

Could you give me some more details on your second problem? The get_ssurgo method downloads data by SSURGO study area serially and then stitches them together; in theory, it doesn't have a maximum area of interest size.

ok if there is no maxiumum size, I'm wondering if its a difference in projection issue? The spatial object is a dissolved set of HUC12 boundaries, and I have reprojected it to EPSG:4326 ("GCS_WGS_1984"). If it will help more I can send you the shapefile and my code?

That would be great. The function reprojects the aoi for you, so I’m thinking that probably isn’t it. Thanks! KB

ok, here is the code, and the shapefile

Thanks for your help!

Hey hey. Alright, I pushed a fix last night. Your area of interest wasn't too big, but what's interesting about it is that its bounding box overlapped some SSURGO survey areas that the AOI didn't. There was a line in the code that cropped each survey area prior to merging them all together, and it was choking on cropping by non-overlapping areas. It should work for you now. Keep in mind that this is in the development version... I'm continuing to make changes here (having frozen the CRAN version), and so keep an eye on the NEWS.md file for API changes.

I'm going to close this now, but please let me know that you were able to get the data you needed.

yep it downloaded now, thanks!
