Queries ScienceBase based on a spatial bounding box. Accepts either an sp spatial data object (uses the spatial object's bounding box) or long/lat coordinates defining the bounding box limits.
Arguments
- bbox
An sf spatial data object. The bounding box of the object is used for the query.
- long
A vector of longitude values that will define the boundaries of a bounding box. Min and Max of supplied longitudes are used. (alternate option to bbox).
- lat
A vector of latitude values that will define the boundaries of a bounding box. Min and Max of supplied latitude are used. (alternate option to bbox).
- bb_wkt
A character string using the Well Known Text (WKT) standard for defining spatial data. Must be a POLYGON WKT object.
- ...
Additional parameters are passed on to
GET- limit
Maximum number of returned items. Will do paging to retrieve results when limit is over 1000. Use with caution, queries 10k results are slow.
Examples
# \donttest{
#specify the latitude and longitude points to define the bounding box range.
# This is simply bottom left and top right points
query_sb_spatial(long=c(-104.4, -95.1), lat=c(37.5, 41.0), limit=3)
