spatialsearch: Find records within some distance of a point given latitude and longitude.

Description

Searches by decimal latitude and longitude to return any occurrence record within the input distance (radius) of the input point.

Usage

spatialsearch(lat, long, radius, limit = 1000, compact = TRUE,
  verbose = TRUE, ...)

Arguments

lat

Latitude of the central point, in decimal degrees (numeric) Required.

long

Longitude of the central point, in decimal degrees (numeric) Required.

radius

Radius to search, in meters (numeric). There is no default value for this parameter. Required.

limit

(numeric) Limit on the number of records returned. If >1000 results, we use a cursor internally, but you should still get up to the results you asked for. See also bigsearch to get larger result sets in a text file via email.
