request elevation for bbox without leaflet view

[m0ose]

The function getBBoxDataSet requires a Leaflet map and an elevation layer to be added to that map. It would be nice to be able to load elevation for a bbox without the leaflet map at all.

agentscript/gis/LeafletDataSet.js

Lines 83 to 84 in 3e2a6e7

	async getBBoxDataSet(bbox) {
	if (!Array.isArray(bbox)) bbox = gis.Lbounds2bbox(bbox)

Yes indeed! Could you submit an Issue? Helps me prioritize. Thanks!

Oops, didn't see that it WAS an issue. Sigh! Thanks

OK: is what you'd like is for

async getBBoxDataSet(bbox)

to use the bbox to discover the required tilles, fetch them, and when all are fetched, proceed to stitch the associated datasets together, get the crop/clip params, and return the single cropped set?

And if it's called several times, manage the set of tiles .. or maybe just rely on the browser cache to do it for me, I'll always do the complete set of fetches and hope the cache works well.

Yeah. That's what I was thinking. Do you think it would be useful?

[m0ose]

Would we need to pass a zoom? or width and height of the final dataset and guess the zoom?

[backspaces]

I think it would be useful, sure. We'd need to pass in a lot of info including the zoom and what the tile rgb dataset would be (TileData.js: mapzen, mapbox, redfish etc).

Completed gis/BBoxDataSet.js in, converted gis/droplets.html and other users of LeafletDataSet to use it. Removed LeafletDataSet from repo.
