A Unique Identifier is a numeric or alphanumeric value that is assigned to each service point in a dataset
to unambiguously distinguish between them. An example of a unique identifier is the ID number of a
person. The ID number is unique and never changes.

Spatial information survey

A spatial information survey involves teams of fieldworkers visiting every service point of your department
to define its geographic coordinates using a Global Navigation Satellite System (GNSS) receiver, such as
a Global Positioning System (GPS). A GNSS allows small electronic receivers to determine their location
(longitude, latitude, and altitude/elevation) to high precision. The system can be used for providing
position, navigation or for tracking the position of something fitted with a receiver (satellite tracking).

An audit of the infrastructure, equipment, beneficiaries and personnel at each service point may also be
collected during the survey. Although this survey methodology provides the most accurate information,
it could possibly be the most expensive and time-consuming.
The steps normally followed in implementing a spatial information survey are:

 Obtain a complete list of government service points.
 Recruit and train fieldwork teams with access to GPS devices.
 Develop a questionnaire for the collection of information on infrastructure, equipment, beneficiaries
and personnel at the service point.
 Work with departmental staff to identify the location of service points.
 Undertake the spatial information survey, capturing the geographic location of service points and
associated attributes.

Mapping workshops can assist in identifying the location of service points
