Reverse Geocoding Options

The Reverse Geocoding category provides options that let you set searching and matching criteria. The following sections cover the reverse geocoding global defaults options, which are available for all countries, and the country-specific reverse geocoding options, which apply to a subset of countries.

Global Defaults

If you modify a global defaults option, then that selection is applied to all countries and cannot be changed on a per-country basis.


Option Name	Country Support	Description
Search Distance	All	Sets the distance of the radius in which to search for a match to the input coordinates. This value can be specified in either feet or meters. Default = 150 meters. Maximum value = 5280 feet (1 mile) or 1609 meters.
Street Offset	All	Specifies the offset distance from the street segments to use in street-level geocoding. The offset distance is used in street-level geocoding to prevent the geocode from being in the middle of a street. It compensates for the fact that street-level geocoding returns a latitude and longitude point in the center of the street where the address is located. Since the building represented by an address is not on the street itself, you do not want the geocode for an address to be a point on the street. Instead, you want the geocode to represent the location of the building which sits next to the street. For example, an offset of 50 feet means that the geocode will represent a point 50 feet back from the center of the street. The distance is calculated perpendicular to the portion of the street segment for the address. Offset is also used to prevent addresses across the street from each other from being given the same point. Default value = 7 meters. The following diagram shows an offset point in relation to the original point. You can select either Feet or Meters for your unit of measurement.
Corner Offset	All	Specifies the distance to offset the street end points in street-level matching. This value is used to prevent addresses at street corners from being given the same geocode as the intersection. Defines the offset position of the geocoded point with respect to the corner. Default value = 7 meters. The following diagram compares the end points of a street to offset end points. You can select either Feet or Meters for your unit of measurement.
Coordinate System	All	Specifies the coordinate system that you want to convert the geometry to. The format must be the European Petroleum Survey Group (EPSG) code or the SRID code. Default = epsg:4326.

County-Specific Reverse Geocoding Options


Option Name	Country Support	Description
Find Options	USA	These options set the constraints to use when matching. Nearest Address Attempts to match to the nearest address. Default = enabled. Nearest Intersection Attempts to match to the nearest intersection match. Default = disabled. Nearest Unranged Segment Attempts to match to the nearest unranged segment. Default = disabled. Prefer Match to Closest Point Attempts to match to the nearest point address within the search radius, rather than to the closest feature (e.g. street segment or intersection as well as point addresses). Default = disabled. Note: This feature requires that at least one points dataset and one streets dataset are loaded; otherwise, the match will be made to the closest feature.
Keep Multiple Matches	USA	Sets the maximum number of match candidates to be returned. Enabled Return all match candidates. Disabled Return only the best match candidate. Default.
