this function provides a consistent data access protocol (dap) to a wide range of local and remote resources including VRT, TDS, NetCDF
Define and get data from a DAP resource
Usage
dap(
URL = NULL,
catalog = NULL,
AOI = NULL,
startDate = NULL,
endDate = NULL,
varname = NULL,
grid = NULL,
start = NULL,
end = NULL,
toptobottom = FALSE,
ID = NULL,
verbose = TRUE
)Arguments
- URL
local file path or URL
- catalog
subset of open.dap catalog
- AOI
an sf of SpatVect point or polygon to extract data for
- startDate
a start date given as "YYYY-MM-DD" to extract data for
- endDate
an end date given as "YYYY-MM-DD" to extract data for
- varname
variable name to extract (e.g. tmin)
- grid
a list containing an extent (), and crs
- start
for non "dated" items, start can be called by index
- end
for non "dated" items, end can be called by index
- toptobottom
should data be inverse?
- ID
a column of unique identifiers
- verbose
Should dap_summary be printed?
Details
Wraps dap_get and dap_crop into one. If AOI is NULL no spatial crop is executed. If startDate AND endDate are NULL, no temporal crop is executed. If just endDate is NULL it defaults to the startDate.
