I've been thinking about buying a drone to take photos and videos while I'm out doing fieldwork that I can use to promote the upcoming event, but also to augment my fieldwork capacity while mapping.
While I was online window-shopping, it occurred to me (as it occasionally does) to also check on the state of the technology to see if there are yet consumer-level lidar or photo-based (structure from motion, or SfM) methods available at a reasonable price. To my delight, it seems that there are, at least via WebODM (Open Drone Map)
, which it seems can generate possibly useful mapping data, including elevation models useful for generating good basemap contours, taking as input anything from high-resolution aerial images to smartphone pics.
Given that lidar data is not available everywhere, and the commercial and DIY lidar solutions seem expensive, I'd really like to develop the capacity to make my own orienteering-precision basemaps, at least of fairly open areas.
Does anyone here have experience doing this, and if you do, can you offer any guidance to a novice wanting to get into this?
