I’ve undertaken the task of mapping Inveralmond Industrial Estate, which lies close to my location but is currently not mapped in any great detail. While most buildings were drawn onto the map fifteen years ago, only about 25 businesses have been added since then—and I contributed half a dozen of those entries just a few months ago. At least two businesses that were added years ago have since closed permanently. Last Sunday, I conducted a preliminary survey of the area, capturing dashcam footage that helped me compile a list of fifty additional unmapped businesses. This number will likely grow substantially, as I left out the minor roads in the estate during this initial pass. My estimate is that the final count could easily reach one hundred businesses. This pattern reflects a broader issue: industrial areas consistently suffer from poor mapping coverage. That’s my take on it anyway from the areas I’ve looked at. I’m currently testing the iOS app Every Door, and plan to conduct comprehensive field mapping in the coming weeks. My goal is to document everything from the largest manufacturing facilities down to the most modest infrastructure, including grit bins. osm.org/#map=16/56.41782/-3.47651
