What are Caltopo's current viewpoints about the pros and cons of and usefulness of snow depth layers (ex. SNODAS) versus imagery (ex. Sentinel satellite imagery)?

(In the past, Matt has shared his viewpoints about this topic and has been very helpful.

Thanks, great products!

    Related to maps, tools, and layers related to assessing snow coverage and snow-depth, can you tell me anything about the snow-depth layer in this map? (ex. how often is it updated, is this a CalTopop created-layer or a user-created layer, etc.)

    I'm also thinking that the layer in this map might help you assess and compare the usefulness of snow-depth estimates vs. imagery

    Thanks again!

    I'm sorry but I don't understand what you are looking for that is more than what was shared in this post:

    We don't have any additional perspective to offer at this time. CalTopo does not have a snow depth layer at this time, and if we do ever offer one it will be based on external data.
