What does “Resolution” mean and how do I choose the correct resolution for my needs?

Support Category: 

The resolution of the aerial photography determines the amount of detail you can see when you view the image and zoom in. A digital image is made up of pixels and the resolution describes the distance on the ground represented by each pixel.

  • For most of England, along with South Wales and areas in the central belt of Scotland this is 12.5cm per pixel
  • In more rural areas such as Scotland, Mid and North Wales and Counties like Cumbria the resolution is lower at 25cm

The resolution you need depends on what you intend to use the imagery for

The correct resolution for you will be determined by how you intend to use the aerial photograph once you have purchased it.

  • For example, if the aerial photograph is being purchased to aid with a boundary dispute or planning issue we recommend you purchase the default highest resolution image available in that area
  • If you are interested in printing to an specific size our Sales Team can advise you on the optimal resolution required. If the print covers this covers a large geographic area, or is only being printed on a flyer a lowers resolution is recommended
     

Things to consider when buying aerial imagery online

  • If buying aerial imagery data from Getmapping online, our webshop automatically defaults to the highest or most detailed resolution in an area.However if you are buying a very large geographic area there is the option to lower the resolution to 25cm per pixel, 50cm, 1m and 2m before buying the image
  • There is a direct link between the resolution of the image and the file size, if you are buying an area larger than 3km x 3km you may want to consider reducing the resolution as otherwise the file may become too large for you to open or manage easily
