Step-by-step guides for creating a MapSwipe Locate Objects project, building its tutorial, publishing it, downloading the results and creating a training dataset. The site also hosts five helper pages: the area finder, which finds the imagery footprint, uses it or drawn shapes as the area of interest, and prepares the cover image; the tutorial builder, for picking tutorial tiles and marking their answers; the imagery merger, which merges several images into one tile URL; the results map, which turns the aggregated results into GeoJSON cells marked by a chosen share of volunteers; and the auto labeller, for marking each object on those tiles with a rotated box or an outline, or loading labels from a GeoJSON file, and downloading them as a YOLO oriented bounding box or segmentation dataset with a GeoJSON of the labels.
