Google Maps:
Google Maps is a fantastic tool for both navigation to locations and location planning thanks to up-to-date maps and the ability to view Terrain, Satellite and Street View versions of maps. Another feature is the ability to right mouse click on the map to select the option
to measure a distance, which can be useful when planning a landing and take-off location in relation to the desired subject to ensure
you’re within the 500m limit, and that you’ll have a clear visual line of sight of the aircraft.

The Photographer’s Ephemeris:
While this app is most commonly used by photographers to assess the position of the sun at sunrise and sunset using Google Maps within the app, it’s for this very reason a great tool for drone photography, too. Whether you plan to shoot around these times or in the middle of the day, you’ll be able to judge how your chosen location/subject will be lit by the sun before you even leave the house. This app is available for both Android and iOS and costs £2.69 and £9.99, respectively.

ViewRanger: If you enjoy walking and the great outdoors, ViewRanger will likely be a familiar mapping app. The free version of the app allows you to view maps and plan shoots at locations while you have a data connection, but with a subscription you gain access to OS Maps and the ability to download maps for offline use, among other features, when you don’t have a phone signal – something that’s essential in some locations.
A one-year Premium+Maps subscription costs £24.99 for both Android and iOS.
