Freeform Search and The Reverse Geocoding

Freeform search is now available and released, this means that one can now build search query with no difference in word ordering. In simpler terms, Mumbai, 43 Blue Mountains and 43 Blue Mountains, Mumbai will return the same results – this was not the case in previous scenario.

Thus, it allows user to search for an address using a freeform text string, thus making the system more user-friendly. Some of the popular searches go around as Freeform address search, Freeform POI search,  and Postcode freeform search, Date freeform search, etc.

Reverse geocoding is the process of reverse coding of the point location to a readable address or place name. In simpler terms, the back process of geocoding is known as reverse geocoding. Combined with geocoding, the reverse geocoding is a critical component of mobile location-based services obtained by GPS to a street address which is easier to understand by the end user.

Reverse geocoding finds the object which is closest to the certain point or object. Reverse geocoding requires manual input of a coordinate, capture from a GPS, or selection of a point on an interactive map – to look up for a particular physical address or a place, street, etc.

Drawbacks of Reverse Geocoding:

This fresh approach of geocoding as such does not return actual addresses, only estimates of what should be there based on the predetermined range. The limitation of accuracy and timeliness of the reference layer used to reverse geocode a coordinate will definitely have a significant impact on the accuracy of the results.

At SPEC INDIA, we are lot more concerned about the requirements of the Clients for the GPS based projects in mobile applications development. The GPS applications are basically working on the geocode structures fetching and then performing the desired operations using the same in the mobile applications development.
