[R-sig-Geo] Help with GeoRSS

[Michael Denslow]

Hello Everyone,

I am trying to read a GeoRSS file using library rgdal and can't seem
to get it to work. I suspect that it is because I am not specifying
the layer = argument correctly (or the dsn). Am I missing something
obvious? I am not clear what goes into this argument for this type of
file.

Some sample code:

library(rgdal)
# says GeoRSS TRUE
ogrDrivers()
getGDALVersionInfo()
# [1] "GDAL 1.8.0, released 2011/01/12"

# ERROR says 'GDAL Error 4: Failed to read GeoJSON data'
ogrInfo(dsn='http://earthquake.usgs.gov/earthquakes/catalogs/eqs7day-M5.xml',
	layer = 'USGS M 5+ Earthquakes')


Additionally, I am not sure why GDAL thinks the file is a GeoJSON. I also tried:

# OGRGeoJSON is apparently the predefined layer name
ogrInfo(dsn='http://earthquake.usgs.gov/earthquakes/catalogs/eqs7day-M5.xml',
	layer = 'OGRGeoJSON')


Thanks in advance for any help you can provide,
Michael
