In compiling map data, a server communicates with a programmable device and determines an authorization level of the device or a user of the device by comparing an authorization request with maintained authorization data; the server receives from the device first geocoordinates, a first property location identifier, and a first location description, the first geocoordinates locating a geoposition on or near a property identified by the first property location identifier; and the server incorporates one or more of the first geocoordinates, the first property location identifier, and the first location description into a database including a plurality of geocoordinates, if the determined authorization level matches or exceeds a property authorization level, wherein the property authorization level is associated with the property and is indicative of whether one of the user or the device is authorized to submit for incorporation into the database geocoordinate information and/or location description information for the property.
