Our Geocoding Data

Accurate geocoding algorithms are the key to location intelligence. Because address databases are often filled with errors, typos, and inconsistencies, it’s sometimes difficult to match stored data with actual coordinates. Melissa combs through over 30 million individual addresses in the UK and utilises precise mathematical location algorithms and street shape maps to select the best recorded point.

Melissa’s Geocoding solution incorporates data from multiple sources, including spatial data, navigational data, and census data. All sources are evaluated and intelligently merged to produce the most precise coordinates possible.

Street Route – Driving Distance Calculation

Melissa’s Street Route API is an easy-to-use developer tool that takes two latitude/longitude coordinates (or a batch of points) and returns the driving distance and total driving time between them. Street Route is useful for determining emergency response and disaster relief planning.

  • Create a “Find the Nearest Location” tool. Using a database of “known/owner destinations”, Street Route can compare a starting point location to the database to return all the route distances and drive times to the possible destinations which can then be queried to present the shortest distance or travel time.
  • Determine geolocations which cannot be reached by vehicle travel. This is helpful in determining latitude/longitude coordinates located on islands or rural off road residences and differentiates Street Route from competing tools that return “as the crow flies” distances.
  • Support for North America, South America, Europe and other regions/countries coming soon.

Frequently Asked Questions

Geocoding is the process of converting a textual address or description into geographic coordinates, typically latitude and longitude. It involves taking a location identifier, such as a street address, postal code, or place name, and transforming it into a specific geographic point on the Earth's surface. Geocoding allows locations to be identified and mapped accurately on a digital map or a Geographic Information System (GIS).

Rooftop geocoding is a method used in geospatial analysis and mapping to determine the precise geographic coordinates (latitude and longitude) of a specific rooftop or building address. Traditional geocoding methods typically assign coordinates to the center point of a given address, which can be a problem when the address covers a large area, such as a building complex or a sprawling property.

In rooftop geocoding, the aim is to pinpoint the exact location on the rooftop of a building or structure associated with a specific address. This level of precision is particularly useful in applications that require accurate spatial information, such as emergency response, logistics, navigation, or targeted marketing.

Rooftop geocoding can enhance the accuracy and reliability of location-based services by ensuring that the coordinates provided align with the intended destination on a building or rooftop, rather than a generalised location within the address area.

The geocoding process uses various data sources, such as address databases, street maps, and reference data, to match the input location information with known geographic coordinates. These data sources often contain information about the spatial boundaries of regions, streets, landmarks, and other relevant features. By analysing and comparing the input information against these sources, geocoding algorithms determine the most probable geographic coordinates associated with the given location description.

Geocoding has numerous applications across different fields. It is widely used in mapping and navigation systems, as well as in location-based services, such as ride-sharing apps, food delivery services, and real estate applications. Geocoding also plays a crucial role in spatial analysis, urban planning, emergency response, and business operations that rely on accurate location information.

A Geocoding API can work in various ways, here 5 examples

  1. API Request: The developer constructs an HTTP request to the Geocoding API endpoint, specifying the address or location information they want to geocode. This request is typically made using the HTTP GET or POST method and includes parameters such as the address, API key (if required), and any additional options or filters.
  2. API Communication: The client application sends the API request to the Geocoding API server using the appropriate URL and endpoint. The API server receives the request and validates it, checking for required parameters and authentication if an API key is necessary.
  3. Geocoding Process: The Geocoding API server processes the request by applying its geocoding algorithms and accessing its geospatial databases. The server attempts to match the provided address or location information with the available data sources to find the most accurate geographic coordinates.
  4. Geocoding Results: Once the geocoding process is complete, the Geocoding API server generates a response containing the geocoded results. This response is typically formatted in a machine-readable format like JSON (JavaScript Object Notation) or XML (Extensible Markup Language). The response includes the latitude and longitude coordinates corresponding to the input location, along with additional information such as the formatted address, administrative boundaries, and possibly other metadata.
  5. API Response: The Geocoding API server sends the geocoding response back to the client application as an HTTP response. The client application can then parse and extract the relevant information from the response to use it in their application as needed.

Geocoding plays a crucial role in address verification by converting a textual address into geographic coordinates (latitude and longitude). By associating precise coordinates with an address, geocoding enables various address verification techniques and enhances the accuracy of the verification process.

This includes providing geographical context, enabling validation, standardisation, distance calculations, and facilitating fraud detection. It helps ensure that addresses are accurate, valid, and exist in the expected locations, contributing to reliable and effective address verification systems.
