Inspector app improvements

[bdon]

• SVG tile previews should be zoomable
• Should be able to drill down into leaf directories
• should be able to preview vector tiles in leaflet
• SVG should be feature-level inspectable
• map preview should be feature-level inspectable
• see directory Len and header-level metadata
• inspect SVG with mismatched extents
• correctly read tile and map hash states
• split out "individual tile inspector" to separate page
• view raw zxy and TIleJSON endpoints

• Display labels from TileJSON

I'd like to port pmtiles.io to use https://github.com/maplibre/maplibre-gl-inspect , since that's what maps.protomaps.com and Maputnik are using.

Other nice feature would be to load a pmtiles url not only on click on load button, but also on press ENTER in the url text input field

The inspector should also accept TileJSON and full Style JSONs to display, just for convenience. Raw Z/X/Y URLs won't work since we don't have enough metadata to derive vector_layers for inspection.

Actually, I think both implementations have their merits (I like how pmtiles.io works with popup freezing and treats each source layer as a group, with possibly different geometry types). For the metadata, maplibre-gl-inspect only needs a list of layers present in the source (e.g. ["water", ...]).

btw, I noticed that switching from Map View to Tile Inspector does not work for local files (you have to drag the file again)

[bdon]

Yeah, the plan is to keep tile inspector as a separate page instead of all under one single page app, because trying to manage the hash state gets too complicated.

It would be helpful to perform light validation of the PMTiles header/metadata to assist implementers

Maybe support IFrames to allow embedding the x-ray map view

Make sure #537 is supported
