GI

gi matters

Geographic information is everywhere. In fact, you wouldn't be able to read this now without the help of gi! Broadband/internet providers need to know where you are, and where the nearest telephone exchange is in order to get you connected successfully - using gi all this can be done at a touch of a button.

What is GIS?

GIS stands for geographic information system and is software that displays digital map data and allows users to query and analyse that data. GIS software has evolved from a combination of two well established types of software: the way in which map features are handled is based on graphics and computer-aided-design (CAD) technology; the way in which attribute information is handled has been developed from conventional spreadsheet and database technology.

There is a large industry in GIS software, with hundreds of companies producing thousands of products and solutions. Many of these are partners with Ordnance Survey, who we work with closely to sell our products and whose software can be used to question and analyse Ordnance Survey data.
