{"id":"public.image_overlay","schema":"public","name":"image_overlay","description":"A raster image (e.g. a hand-drawn map annotation) georeferenced onto lmb-maptwo as a MapLibre image source. geom is the image's top-left corner; width_m is the desired on-the-ground width, height derived from the image's own aspect ratio. filename is a static asset filename served from lmb-maptwo's static dir (e.g. port-blakely-label.png), not a path/URL. See ontologies.mapping.image_overlay_coordinates for the georeferencing math, and the build_map_style_job Dagster asset that regenerates map-style.json from these rows.","properties":[{"name":"yid","type":"int4","description":""},{"name":"filename","type":"text","description":""},{"name":"width_m","type":"float8","description":""},{"name":"note","type":"text","description":""}],"geometrytype":"Point","center":[-122.50535207332189,47.59594869134859],"bounds":[-122.50535207332189,47.59594869134859,-122.50535207332189,47.59594869134859],"minzoom":0,"maxzoom":22,"tileurl":"https://tiles.letsmapbainbridge.org/public.image_overlay/{z}/{x}/{y}.pbf"}
