Data sources for reading

Description

Provides a data frame of online-accessible data sources. This is very incomplete and has no guarantee of success. It's your responsibility to check usage terms.

Usage

gdalio_sources()

Details

There is a table of sources 'provider', 'name', 'source' - source is a DSN in GDAL terms, you can query and read from it with GDAL.

Examples

srcs <- gdalio_sources()
ttsa <- subset(srcs, provider == "tasmap" & name == "TTSA")$source
ve <- subset(srcs, provider == "gdaltms" & name == "wms_virtualearth_street")$source
gdalio_set_default_grid(list(extent = c(-1, 1, -1, 1) * 800,
                             dimension = rep(min(dev.size("px")), 2L),
                             projection = "+proj=laea +lat_0=-42.8826 +lon_0=147.3257"))
source(gdalio_format_source())
tas_street <- gdalio_terra(ttsa, bands = 1:3, resample = "cubic")
ve_street <- gdalio_terra(ve, bands = 1:3, resample = "cubic")
par(mfrow = c(1, 2))
terra::plotRGB(tas_street)
terra::plotRGB(ve_street)
