Street-Level Imagery Provider Overview

A meta-catalog of street-level imagery providers on one full-screen map. Compare where Mapillary, Panoramax, KartaView, Mapilio, Bing Streetside, Vegbilder, Google Street View, and Apple Look Around have coverage, inspect individual photos, and share exactly what you see via the URL.

What you can do

• Compare coverage at a glance — every provider renders as its own dot layer on a full-screen MapLibre map; toggle providers on and off to see who covers your area
• Click to explore — click anywhere on the map to list nearby photo sequences (grouped, sorted by distance) and Mapillary signs / map features in the right panel
• Browse photos — open a sequence to step through its photos with prev/next navigation, thumbnails, and a deep link into the provider's own viewer
• Filter imagery — restrict to flat or panorama photos and/or a capture-date range; map dots, legend counts, and click results all respect the filters
• Switch visualization styles — color dots by photo type (panorama vs flat) or by age (≤ 2 years / 2–4 years / > 4 years), with newer imagery drawn on top
• Read live legends — under each enabled provider, counts of what is currently in the viewport, broken down by the active style's categories
• Open a place elsewhere — the pointer button next to a provider opens a place in that provider's own viewer: click it, then click the map (Shift+click opens the map center right away). Mapillary opens the nearest photo already turned to the place; infra3D (login required) looks at the clicked spot from the nearest image
• Share any view — viewport, providers, style, filters, click location, and photo selection are all in the URL, so links restore the exact state on reload

Only Mapillary and Panoramax are enabled by default; the other providers are one click away. The Mapillary signs and map-features overlays are separate toggles (off by default — they are dense enough to bury the photo layers). Google Street View is click-only (no map dots or in-app imagery): without a key it is just an "Open in Google Street View" button; with GOOGLE_MAPS_API_KEY in src/config.ts (a restricted browser key with the Street View Static API enabled) it gets a checkbox that checks coverage through the Street View Static metadata API when you click the map, and the button opens the panorama turned to the place. Bing Streetside is an open-only button too unless BING_MAPS_KEY is set in src/config.ts; with a key it becomes a map overlay (Microsoft issues no new Bing Maps keys, existing enterprise keys work until June 30, 2028). Apple Look Around and infra3D are open-only buttons: neither publishes a coverage listing, so there is nothing to draw on the map. Apple opens maps.apple.com/look-around (no API key); links that still carry lookaround in providers keep the click card, with a MapKit JS preview when VITE_APPLE_MAPKIT_TOKEN is set. infra3D gets one button per project listed in INFRA3D_PROJECTS in src/config.ts (id and name; right now the Berlin project with the drives of 2025 and 2021/22) and needs an infra3D account. Full Look Around coverage dots are blocked without an official listing API — see docs/lookaround-coverage-spike.md. Panoramax traffic signs are not available: the public Panoramax MVT endpoint only exposes pictures / sequences layers, and the iD editor does not implement a Panoramax signs overlay either — see docs/id-provider-research.md.

API keys

Google Street View and Bing Streetside are "Open in …" buttons by default. Each becomes more with a key in src/config.ts:

Provider	Setting	With the key	Getting one
Google Street View	GOOGLE_MAPS_API_KEY	A checkbox that checks coverage where you click; the button opens the panorama turned to the place.	A restricted browser key with the Street View Static API enabled; see docs/viewpoint-photo-finder-plan.md.
Bing Streetside	BING_MAPS_KEY	A map overlay with the panorama positions.	Microsoft issues no new Bing Maps keys. Existing enterprise keys work until June 30, 2028. Streetside has no coverage in Germany.

The keys ship in the JS bundle, so restrict them on the provider's side (HTTP referrer, API allow-list, quotas).

URL state

Map viewport, enabled providers, visualization style, photo-type filters, optional date range, click location, and photo selection are encoded in the query string so links can be shared and restored on reload. Filters and date semantics follow the iD editor's behavior (photos match on capture date; signs/map features match on first/last-seen dates).
