Belmap API

Enhance your applications with the best location data

Are you having difficulty managing data efficiently and would you prefer to rely on an externally managed database? Are you using a variety of data sources and but are finding that they simply won’t work together? If so, the Belmap API continually supplies your apps and websites with the most recent information concerning addresses, buildings and cadastral parcels.

Seamlessly integrated into your applications

An API (Application Programming Interface) is a bit of a mouthful for such a simple solution. The Belmap API creates an interface between your application and the database. That way, you can easily request location data and integrate it into your applications. For example, this could be an address, a coordinate or any other Belmap data module.

Fast and easy data access

Using the Belmap API takes away all the hassle of managing the data. You can simply request the information anywhere, whenever you need it. With the API, you always have access to the most accurate and up-to-date information. Customers use it to support their digital transformation, to perform on-site interventions and field surveys and to ensure flawless logistics. 

Safe and flexible

Communication with the Belmap API takes place by means of a secure connection. In addition, GIM takes care of the complete management of the servers and adjusts the capacity of the service according to peak or off-peak periods.

A wide range of API Services

With the Belmap API, you can choose from the following services:

  • Address Autocomplete: smart address suggestions based on the input a user is typing, so as to guide the user to the intended address more rapidly.
  • Address Normalization: an optimised address matching service to correct/standardise the spelling of addresses.
  • Address Geocoding: retrieve the geographical location of an address.
  • Address Reverse Geocoding: retrieve the closest address for a provided geographical coordinate.
  • Entity Information: retrieve information concerning a single building, address, parcel or Geocell.
  • Geo Analytics Service: make custom queries. Combine all information available in Belmap to get the answer you are looking for. Examples of custom queries include: retrieving "all addresses within a particular area having a flat roof with a surface area of at least 200 m2 and no solar panels yet installed," or defining "how many inhabitants live within a radius of 1 km around a coordinate where an incident happened."

The Belmap API comes with an API developer's portal (Open API based) containing technical documentation required in order to understand, test and experiment with all the functionalities of the Belmap API.
