Geocoding services - What are they?
Geocoding (sometimes called
forward geocoding) is the process
of enriching a description of a
location, most typically a postal
address or place name, with
geographic coordinates
(Long & Lat).

Reverse Geocoding services
Reverse geocoding is the process of back (reverse) coding of a point location
(latitude, longitude) to a readable address or place name.

Forward Geocoding converts or
enriches a human readable
address to a computer readable
address.
Reverse Geocoding converts or
enriches a computer readable

Geocoding services - Considerations
Considerations when implementing reverse
geocoding:
• Various geocoding services providers
• Paid solutions vs Free solutions
• Geographic coverage
• Performance of the solution
• Uptime
• Number of geocoding requests that you
expect to process a day
• Compatibility of Geographic/Administrative
layers
• Device & Browser compatibility

Geocoding services – Concluding remarks
• Our stakeholders are getting used to consuming byte size information
as and when they need to from mobile devices.
• As National Statistics Agencies, we need to constantly reimagine how
we package and, equally important, distribute our products.
• Reverse Geocoding Services provide a simple and cost effective way to
disseminate information while reducing the burden for the users
