# Places basemap (optional)
|
|||
|
|
|
|||
|
|
The **Places** photo map renders your geotagged photos as clusters. It works
|
|||
|
|
out of the box **without** a basemap (clusters on a plain background). To get a
|
|||
|
|
real street/terrain backdrop, drop a self-hosted vector basemap here — no
|
|||
|
|
third-party tile API, fully offline.
|
|||
|
|
|
|||
|
|
## How it works (Approach "A")
|
|||
|
|
|
|||
|
|
OxiCloud already serves `static/` through `tower-http`'s `ServeDir`, which
|
|||
|
|
honours **HTTP Range** requests. A [PMTiles](https://docs.protomaps.com/pmtiles/)
|
|||
|
|
basemap is a *single file* read directly by the browser via Range — so the
|
|||
|
|
basemap is just a static file the app already knows how to serve. No extra
|
|||
|
|
backend, no tile server, no API keys.
|
|||
|
|
|
|||
|
|
## Enabling it
|
|||
|
|
|
|||
|
|
1. Get a Protomaps `.pmtiles` basemap (vector, ODbL OpenStreetMap data):
|
|||
|
|
- Whole planet z0–15 (~120 GB) or a smaller global `z0-6` (~60 MB), or
|
|||
|
|
- A **regional extract** (recommended — only the area you need, a few MB):
|
|||
|
|
```sh
|
|||
|
|
# one-time, downloads only your bounding box from the remote planet
|
|||
|
|
pmtiles extract https://build.protomaps.com/<DATE>.pmtiles basemap.pmtiles \
|
|||
|
|
--bbox=<west>,<south>,<east>,<north>
|
|||
|
|
```
|
|||
|
|
See https://docs.protomaps.com/basemaps/downloads
|
|||
|
|
2. Place it here as **`static/basemaps/basemap.pmtiles`** (this path is
|
|||
|
|
git-ignored on purpose — see `.gitignore`).
|
|||
|
|
3. Reload the Places view. The map will pick it up automatically.
|
|||
|
|
|
|||
|
|
The bundled style is **label-light** (water / land / roads / buildings, no
|
|||
|
|
text) so it needs no glyph/sprite assets. Attribution “© OpenStreetMap”
|
|||
|
|
(ODbL) is shown automatically when a basemap is present.
