Map Filtering #8

Open miklb opened 5 years ago

miklb commented 5 years ago

while introducing the Mapbox GL map, we have opportunity to detail how best to filter and if any other layer data would be useful.

For instance, this has evacuation routes layered. Could we show layers based on pre-landfall/post?

sbma44 commented 5 years ago

Absolutely. Here's an example showing how to toggle layers: https://www.mapbox.com/mapbox-gl-js/example/toggle-layers/

It's also possible to dynamically modify filters that determine which elements within a layer are rendered. This can be used in a lot of interesting ways to create dynamic displays.

(Note that it's probably not a good fit for a dataset like the shelters that can change rapidly--adding new shelters does require re-uploading the tileset, which can be automated but involves some async processing)

which can be automated but involves some async processing

is that in reference to just the layers or in general? If a new shelter was added right now, would it display?
