What is Geocoding?


When geocoding, localizing or georeferencing, spatial information is assigned to a data set. Geocoding requires specific software also known as a geocoder. The geocoder uses intelligent software to search a reference database to find the most suitable and exact coordinate for each data record (e.g. address) and assigns it an X/Y coordinate. This allows addresses to be located and displayed on a map. The geocoder takes into account specific country and language characteristics during the localization process.
Geocoding is the basis for geomarketing. Only with the geocoding process are you able to display your addresses on a map as points or as geometric shapes for an entire area.

Software for Geocoding

With JoinAddress, WIGeoGIS offers one of the best and most modern geocoders in Europe. JoinAddress Web uses several methods to determine the best possible geo-coordinates for an address. If an address is incorrect or incomplete, JoinAddress Web provides convenient functions for correction. You receive correct addresses and exact coordinates. The Geocoder JoinAddress has also been available as an online service since 2017. After registering, you can test JoinAddress Web without obligation and geocode 400 addresses free of charge.


Geocoding in Practice

Use of Coordinates in Companies

Geocoding is the basis for numerous company applications. Geocoding allows you to localize your addresses and visualize them on the map. The localization of addresses is an important prerequisite for geomarketing analyses and Location Intelligence Applications. You see your addresses in a spatial context and gain a new, important perspective for your business decisions. This perspective can be decisive for your business success.

Your addresses from customer databases, your branch networks and service centers as well as the locations of the competition are shown on the map. You can use the data in many ways. In combination with other key figures or market data from your company, geocoded address data serves as the basis for numerous sales, expansion, service and marketing measures.

Geocoding means assigning an address a spatial reference through XY coordinates. It is also possible to link a GPS coordinate with the corresponding address. This is called reverse geocoding. Geocoding is what makes spatial analysis with addresses possible.
Simply register on the start page of the application, purchase a quota, upload your data and start geocoding. The first 400 addresses are free.
Your addresses are temporarily stored on the WIGeoGIS geocoding server. The data is then processed on the server. After the geocoding process is finished, you download your geocoding results (your starting addresses supplemented with geographic coordinates). You can then delete your address list from our server.
You can upload your addresses as an Excel list or as a text file. You can also download your geocoding results in one of the two data formats.
The ISO-3 code is an international standard defined by the International Organization for Standardization ( This organization defined country codes for each country providing them a unique, internationally recognized abbreviation. We work with this international standard for our geocoding. If you provide an address with an ISO-3 code, the geocoder can immediately assign it to the respective country. You can download a list of the ISO-3 codes here.
Generally, the geocoding accuracy depends on the coverage of the respective country. In places where the data depth is still low, detailed geocoding is not possible. WIGeoGIS works together with all the popular commercial data and service providers (TomTom, HERE, Bing) and provides the greatest possible accuracy for each country. The data is constantly updated, thus improving the accuracy.
