The previous post covered a promising new tool named Input for data collection. As a reminder, this tool involves setting up a QGIS project and using the Mergin plugin to transfer the project and data to and from your computer and smartphone. It is also a free app. Another aspect of Input is that until now it has only been available for Android.
From there is can be used just as was described in the previous post where setting up a project, using Mergin and collected data with Input was described. Once I have had a chance to experiment with it I will follow up with a summary on that. In the meantime, if you are an Apple iOS user, download the app and follow the previous post to give it a trial run.
