Geocoding is the process of converting a location description (such as a coordinate pair, an address, or a place name) into a location on the Earth’s surface. You can perform bulk geocoding by entering a location description one at a time or from a table. The resulting locations are geographic features with attributes that can be us! for mapping or spatial analysis.
Addresses can be us! in geocoding, a process that takes a location description and places the feature on a map. An address is simply a method us! to describe a location. To find an entity by address or other data, you can geocode it.
Geocoding has three main components: Input Data Address Locator and Reference Data
Input data is the first component requir! for geocoding. Input data includes the location description and is provid! by the user. Geocoding uses input data to place features on a map or to orient the map/map user.
Address Locator
Geocoding also requires an address locator, a legacy systems defin!: examples, key problems & solutions tool that connects location descriptions in input data to geographic coordinates to overlay details onto a map.
The address locator contains information about how to parse an address, how to use search methods for possible matches, and how to return match output information.
Address locators are design! to handle many possible variations of a valid address. If an address provides incorrect or insufficient information, you can review and correct address matches, improve address discovery rules, and refine reference data until you get address matches that you are happy with.
The address locator can be stor! locally
publish! as a service using ArcGIS Enterprise, or shar! as a Locator Package in ArcGIS Online. ArcGIS Online also offers the World Geocoding Service, which any you can create valuable content ArcGIS Desktop or ArcGIS Online user can access.
Reference Data
Address locator requires reference data to map you germany cell number can create valuable content details.
The layers you use to create an address locator, known as reference data, must have the details of the specific point you want to find. When searching for an address, the primary reference data usually consists of a street grid, but a parcel map can also be us!. The important thing is that the data has the detail you want to find.
After identifying address elements in the input data, the address locator uses a set of rules to compare address elements from the input data to the reference data. The address locator finds matches between the input and reference data and plots the features on a map. The quality of your search results depends on the quality and accuracy of the input data as well as the reference data. You can also refresh the address locator whenever your reference data is updat!.
