Sketch to GPS

Filter by device

With the Sketch to GPS tool you can use point and line drawing tools to create routes and waypoints to save as a .GPX file. You can upload this file onto to your GPS device for later use in the outdoors.

What about a walking track that you have recorded on your GPS? You can also open  .GPX files with the Sketch to GPS tool and view them on the map.

Additionally, the Sketch to GPS tool allows you to open and save KML/KMZ files. This is useful if you use Google Earth or have KML files from another source that you would like to see on the map.

save Saving and opening a file

The Sketch to GPS tool is compatible with three file types. These are GPX, KML/KMZ, and json. You can save sketches in any one of these file types. Additionally, you can also upload any of files of these types to WAMS.

Attention iOS users: iOS users will NOT be able to save GPX and json files. If you choose to download drawings as either file type a new tab will open but your device will be unable to recognise the file information. If you have a cloud storage service like Dropbox installed on your device, you can choose instead to save as KMZ, a new tab will open from which you will be able to save a file to Dropbox (see below for advice on using Dropbox).

For iOS users it will be handy to have a cloud storage account such as Dropbox  if you want to save KMZ files or open files. You can download the Dropbox app from the App Store. The app can also be downloaded for use on Android devices from Google Play. Such services will be handy for saving and opening files on any device type, it is also a useful way to Share files with others. Head to the Dropbox website to find out more information or how to create an account.
