Mobile phones have rapidly become part of our daily lives and most of us now carry them nearly everywhere we go. Nearly three quarters of us in the UK now own a smartphone1 and these can do so much more than just make calls. With on-board hardware such as a GPS receiver, camera, microphone and accelerometer these devices can, with the right software, do remarkable things. As a permaculture designer my preferred tools for gathering site information and making maps are still pens, pencils and paper, but I also now appreciate the new and powerful tools that my ‘phone’ provides. In this article I’ll introduce you to a few of the apps that I’ve been finding really useful.
Recording site observations
Perhaps where the smartphone really comes into its own is out in the field. Even if I don’t have pen, paper & clipboard with me I can now record a lot of what I see and hear on my phone. In addition to the standard camera and video options, both of which I would always make good use of especially if surveying a site some distance from home, there are apps that can overlay extra information. Up until now I’ve used a Sun compass to identify the sun’s path through the year and this is a great tool, but it has its limitations. Firstly they’re only made for 50˚north, which is fine for Britain, but less useful at different latitudes. It also indicates the rising and setting points on a flat horizon, which we rarely have, so I end up having to guess how the surrounding landscape affects this. Sun Surveyor offers much more precision. It uses GPS to locate itself and then shows you the path of the sun (and moon if you wish) on any date you choose. You can view this information as an overlay on a satellite image or, if you buy the paid version2, through the camera. It’s so useful to be able to move the camera around and see where the sun crosses the horizon and even take a photograph with this information overlaid.
