In all our POI Data Packs information is organised by a unique identifier used to recognise the point of interest: the poi_id field. This field is used as a foreign key to link the different files and/or packages together.
As a customer you might want to complement our information with some data you already own. Provided that your data is also organised as outlined below we can provide a service to match your POI identifiers to our poi_id field. In this way you can then establish a clear link between our information and your pre-existing files.
Technical information
Input file
In order to make this match information we do need an input file from your side. This file must be a CSV file with the following requirements:
- UTF-8 encoding
- New line delimiter:
LF - Field delimiter: comma
, - Escape character: double quotes
“
We need the file to contain name and position of the POI as outlined below:
Field Name | Description | Mandatory | Type |
Customer ID | Unique identifier provided by the customer to create a link between POI ID and customer identifier | NO | STRING |
POI Name | Name of the Point of Interest | YES | STRING |
Latitude | Latitude of a POI (according to the WGS84 standard) | YES* | DOUBLE |
Longitude | Longitude of a POI (according to the WGS84 standard) | YES* | DOUBLE |
Address | Full street address of a POI | YES* | STRING |
* It is mandatory to provide both Latitude and Longitude or, alternatively the Address field.
Output file
As output of this process you will receive a file called Customer Association with fields as defined below:
Field Name | Description | Type |
customer_id | Your own reference | STRING |
poi_id | Our own unique POI identifier.
If no match is detected this field is NULL | STRING |
