What is Geocoding

From simple statistics evaluation to business and client management to distribution strategies, there is a huge range of packages for which geocoding can be used. Georeferenced statistics can be beneficial for visualization, which include mapping places where events of interest occur. Geocoding is also often the first step in linking environmental and health data for a variety of public health purposes, such as research and surveillance. With geocoded addresses, you can spatially show the address locations and understand patterns within the facts. You may also display your address statistics primarily based on certain parameters, allowing you to further examine the statistics.

What is Geocoding

Geocoding is the process of converting an address into geospatial statistics and associating the precise geographical coordinates for that address. Geocoding is based on a pc representation of address factors, the road/road network, collectively with postal and administrative boundaries.

What is Reverse Geocoding

Reverse geocoding is the technique of opposite (reverse) coding of a point location (latitude, longitude) to a clear address or location name. This allows the identification of nearby street addresses locations, and/or region subdivisions together with neighborhoods, county, state, or country. Combined with geocoding and routing services, reverse geocoding could be a crucial component of mobile location.

Geocoding Process

Geocoding could be a task that involves multiple data sets and processes, all of that work along. A geocoder is created of two vital components a reference data set and also the geocoding algorithm. Each of those parts is created from sub-operations and sub-components. Without understanding how the geocoding processes really work, it’s sturdy to make knowledgeable business choices supported geocoding.

Input Data

Geocoding Input data are the descriptive and textual data, for example, location address or building name that the user desires to show into numerical and spatial information i.e: latitude and longitude — through the method of geocoding.

Classification of Input Data

Classification of Geocoding Input data can be done into two categories relative and absolute input data.

Relative Input Data

Relative input data are the textual descriptions of a location that, alone, cannot output a spatial representation of that location. It depends and geographically relative of various reference locations. The best example of a relative geocode is address-interpolation using areal units or line vectors.

Absolute Input Data

An absolute input file is the textual descriptions of a location that, alone, will output a spatial illustration of that location. This information sort outputs an absolute well-known location severally of different locations. For example, USPS ZIP codes, USPS Zip+4 codes, complete and partial postal addresses, USPS PO boxes, cities, counties mind named places can all be referenced in a data sources absolutely.

Uses of Geocoding

From simple statistic evaluation to business and client management to distribution strategies, there is a huge range of packages for which geocoding can be used. Geocoded locations are helpful in many GIS analysis, mapmaking, deciding workflow, transaction mash-up or injected into larger business processes. On the web, geocoding is used in services like routing and native search.

Address data analysis

With geocoded addresses, a user can spatially display the address locations and begin to recognize patterns within the information. The user can also display address information based on certain parameters as per their requirement, which allows them to further analyze the information.

Customer data management

Geocoding acts as a vital part of client data management. Nearly every organization maintains address data for every client or shopper. This is often sometimes in tabular format, containing the client name, address and the other information you have collected. Geocoding allows a user to take customers’ data and create a map of their locations. Using of related applications, the data can be used in many ways for GIS analysis, from establishing marketing strategies to targeting specific clusters of customers to producing route maps and directions. The geocoded locations of customers can be priceless information.

Distributed geocoding applications

The user can use numerous strategies to share the geocoding functionality. These include everything from grouping the address locators and sharing via a compressed file or optical disk to developing a web application, allowing users to perform geocoding over the web.

General tips to keep in mind while Geocoding

1: Clearly verify your geocoding purpose and also the accuracy level needed to fulfill this need. If you simply ought to geocode your information to the city or country level, don’t complicate things with address information. However, if address level accuracy is critical, take the right steps to ensure confidence in your result.

2: Be ready to re-geocode, and refine your information and geocoding method accordingly — several geocoding iterations may be necessary to achieve the required result.

3: if possible, compare your final results with more than one Base map.


There are several Desktop and online geocoders out there, with totally different levels of free and for-pay access. Nowadays more and more business, governmental agencies, and other different entities are realizing that geocoding could be a valuable thing to do for many reasons, this demand has caused a rise in the range of available geocoders.
