Nexiga Geocoder Topics

How to deal with different address spellings?
The completeness of the underlying reference file and the accuracy of the coordinates used are decisive for the quality of geocoding. The program logic in the matching process is also important.

Depending on your needs, you can draw on a variety of sources and structures as the basis for address validation - from the official cadastre and Deutsche Telekom to providers such as TomTom or OpenStreetMap.

Geocoding in practice | Tutorial

Geocoding assigns geographical coordinates (latitude and longitude) to an address or place name. This allows locations to be precisely localized on a map in a geographic information system (GIS) and visualized accordingly.

You can learn how this works in practice in a practical setting.in one of our video tutorials. In Nexiga Market Analyst Pro (GIS), we use examples to show the advan in one of our video tutorials. In Nexiga Market Analyst Pro (GIS), we use examples to show the advantages of geocoding for your address validation.

Unrivaled!

Nexiga Geocoder accesses over 28 million address data and 2.3 million street segments including coordinates and geo keys.

Extra power for customer data - high-speed geocoding

Geocoding refers to the enrichment of postal addresses with geographic xy coordinates on the one hand and/or geographic keys (KGS+) on the other. This defines both the location of a house/address in space and Street segment its administrative affiliation to a Municipality, district, Neighbourhood Street segment .

As part of the process, the Postal code, which is itself a geocode, is also validated and supplemented if necessary. Ten times more detailed than the Zip code the Micro postal code sub-unit developed jointly by Nexiga and MB-Micromarketing.

The coordinate localizes the address, the geo keys allow the counting of addresses, households, customers per area unit and the enrichment of external qualifying information such as purchasing power.

Things to know about geocoding

General information

1. What is geocoding?
Geocoding is the process of assigning geographic coordinates (latitude and longitude) to address data. This turns addresses into exact points on a map. With Nexiga geocoding, companies can precisely locate their data spatially—the basis for analyses, visualizations, and informed decisions.

2. Why is geocoding so important?
Only geocoded data reveals spatial relationships:
Which customers live in which areas? Where are the best locations? How can area structures be optimized? Nexiga provides the data and technology for this—reliably, accurately, and in compliance with data protection regulations.

3. What is the purpose of geocoding?

It is used for address validation. This means checking and correcting address data to ensure that it is complete, correct and deliverable by post. The addresses entered are compared with official reference databases (e.g. from postal service providers or official sources).

3. What is the difference between geocoding and reverse geocoding?

Geocoding: Address → Coordinates
Reverse geocoding: coordinates → address
Nexiga supports both methods - e.g. for determining locations, mobile applications or area analyses.

Technical basics

1. what data is required for geocoding?
Street, house number, Postal code, city and country are usually sufficient. The more complete the information, the more accurate the result. Nexiga can process both structured and unstructured address data.

2. how accurate is Nexiga geocoding?
Nexiga uses official building coordinates and regularly updated reference databases. This enables us to achieve maximum accuracy - right down to building level. An intelligent plausibility check is carried out even in the event of incorrect entries.

3. which coordinate systems are used?
WGS84 as standard (e.g. for GPS data), optionally also ETRS89 or UTM. Nexiga supplies the coordinates in the desired format - depending on the system requirements or GIS environment.

4. how does Nexiga deal with incomplete or incorrect addresses?
The Nexiga Geocoder uses fuzzy matching, recognizes typing errors and compares incomplete data with the extensive address database.
This means that even incorrect data records can be reliably located.

Quality and accuracy

1. how does Nexiga measure the match quality?
Each geocoding receives a so-called match score, which indicates how reliably the address was identified.

The match score is between 0 and 1 and is explained by a description of the input address compared to the reference address.

Example:

1 = 100% match

0.8 = 80% match (house number not found)

0.45 = 45% match (= street in Zip code not found)

In addition to the information on address quality, a further key figure on location accuracy is given for each address.

2. how can quality be further improved?
Through regular data maintenance, standardization of spellings and the use of up-to-date Nexiga reference data. Nexiga also offers address and data quality analyses on request.

Application and integration

1. in which areas is Nexiga geocoding used?

Marketing & sales: target group and territory analyses
Logistics & transport: route planning, location optimization
Energy & Telecommunications: Network planning, supply simulation
Finance: risk assessment, location analyses
Public administration: operational planning, infrastructure development

2. How can Nexiga geocoding be integrated?
Via API interfaces or batch processes. This allows companies to geocode addresses automatically in real time—directly in their CRM, ERP, or web portal.

3. what specific solutions does Nexiga offer?

Nexiga Geocoder API: Real-time geocoding via web service
Batch geocoding: processing large address volumes
Address check service: checking, cleansing and standardization of addresses
Location intelligence platform: combination of geocoding, analysis and visualization

4 What is the difference between batch and real-time geocoding?

Batch: Many addresses at once (e.g. complete customer database)
Real-time: Direct geocoding when entering or checking individual addresses

Further functions

1. How does Nexiga support reverse geocoding?
Our systems can convert coordinates back into addresses or place names—ideal for mobile services, tracking applications, or location determination.

2. What other functions does Nexiga offer in the field of geocoding?

Routing & catchment areas: Determination of distances and travel times
Heatmaps & location analyses: visualization of density, potential or market shares
Territorial structures & geomarketing: planning and analysis according to spatial criteria

3. what role does AI play in the Nexiga Geocoder?
Nexiga integrates machine learning algorithms to detect and correct incorrect addresses. This increases the accuracy and automation of the entire process.

Data protection and legal matters

1. what is Nexiga's position on the GDPR?
Data protection is our top priority. Nexiga processes addresses in strict compliance with the GDPR. A personal reference is not established during geocoding, as addresses are processed anonymously.

2. is personal data stored?
No, no personal data is stored. Only coordinates and technical metadata are generated during geocoding.

3. which legal bases apply?
Nexiga uses licensed data sources (including official geodata, open data and its own databases). All data used is subject to verified license conditions.
