Geographic processing

DSS provides a variety of processors to work with geographic information.

Geopoint converters

Most geographic processors in DSS are based on the Geopoint meaning.

DSS provides two processors to convert between a Geopoint column and latitude/longitude columns:

Resolve GeoIP

The Resolve GeoIP processor uses the GeoIP database ( to resolve an IP address to the associated geographic coordinates.


It produces two kinds of information:

  • Administrative data (country, region, city, …)

  • Geographic data (latitude, longitude)

The output GeoPoint can be used for Map Charts.

Reverse geocoding


To use this processor, you must first install the DSS plugin called “Reverse Geocoding”. Please see Installing plugins.

The reverse geocoding processor takes geographic coordinates as input and extracts the different levels of administrative boundary to which it belongs (country, region, city …). The administrative boundaries we use are the ones defined in Open Street Map. The type of administrative boundary for each level depends on the country. For more information please refer to the Open Street Map documentation.

  • You need a column containing a Geo Point or a Geometry as input.

  • The processor outputs two columns per administrative level for which you provide a column name: one with the local name of the administrative entity and one with the English name.

Zipcode geocoding


To use this processor, you must first install the DSS plugin called “Zipcode geocoding”. Please see Installing plugins.

This processor provides “Country + zipcode” –> “Geographic coordinates” resolution, at the city-level resolution.

  • You need a column containing the country (name or ISO code) and a column containing the zipcode

  • The processor outputs a Geo Point column


The Geo-join processor performs a geographic nearest-neighbor join between two datasets with geo coordinates.


This processor performs the geocoding of an address using either the MapQuest or Bing API.

For details on which kind of addresses are handled, please see the doc of the associated API.


This processor requires the use of an API key for the external services. You must comply to the terms of use of these services

API calls can be expensive, depending on your API key usage terms


This processor (with both API) is extremely slow. Once you are happy with the result, you should export to another dataset so that the processor does not make API call every time you restart the studio.

Create area around a geopoint

The Create area around a geopoint processor performs creation of polygons centered on input geopoints. For each input geospatial point, a spatial polygon is created around it, delimiting the area of influence covered by the point (all the points that fall within a given distance from the geopoint). The shape area of the polygon can be either rectangular or circular (using an approximation) and the size will depend on the selected parameters.
