Geocoding and Georeferencing - meaning, process and benefits
Geocoding and georeferencing support your business to get better understanding of the context it operates in - environment, services, etc. We harmonize maps, data and different types of information in Geographical Information System (GIS).
What is geocoding
Geocoding allows you to transform any description of location into an actual location on earth's surface. These descriptions of locations could take form of lists of coordinates addresses, names of places or lists of named objects/services/buildings without address (only names). The result of this operation is a geographic feature (layer) with all additional information as an attribute table in this layer.
What is the process of geocoding?
to creating a list of all points of interest.
to find the exact location of each item in the table and to upload it in a database with all attributes.
to match the the information in an appropriate geographic coordinate system or projection.
Georeferencing, on the other hand, will align different types of geographic information to a known geographic coordinate system. This allows a view of the respective information together with another already georeferenced layers of information. The process includes data shifting, scaling, rotating, rectifying, etc.
What is georeferencing?
What is the process of georeferencing?
to define the coordinate system of already referenced layers.
aligning the input information to the existing layers with referenced layers.
information uploading in the database together with other layers.
What is the difference between geocoding and georeferencing?
On overall, the difference between geocoding and georeferencing is that geocoding is a procedure to locate a particular point of interest, while georeferencing 'aligns' spatial information to existing mathematical model of the Earth (i.e. geographic coordinate system or its projection on a flat 2D surface - a map).
Both operations allow information consideration, linking and analyzing in one with all additional information sources that are available i.e. statistical, spatial and so on. This provides an opportunity to use the information and make it beneficial for your business instead of just saving it on a server, without an actual use from it. Also you can use it for creating a strategic and competitive advantage on the market that you operate on.
