Did I see roads in the app at one point? This cumulative effects dataset may be worth exploring - integrates roads from several sources image

Caveats being that it was built in 2021, doesn't live update. There is a github repo for the development (sadly not R). Thought it may be of use:

Very nice! I was not aware of this dataset. Sounds like it would be a good idea to change the datasource for the app +1. The app currently uses a hard copy of the DRA. There are many limitations to road datasets in BC. Like construction date.. So very hard to use in a timeseries analysis. The roads don't plot up on the leaflet map automatically in the app. You you have to turn on the layer.

Lemme know if I'm spamming your project here, but if you haven't encountered yet, there is great food for thought from this cumulative effects report

Another suggested data set from this is the human disturbance layer - includes seismic/transmission/rail lines as well

I agree, adding in the cummulative effects workflow for aquatic ecosystems would be a great benefit. We have the WHOPR in the Omineca, which is very similar, and I haven't gotten around to scripting it in a fast way that can be done on the fly. Largely because it depends on VRI which is rather slow. I do have the VRI duplicated in PostGIS, but it's still too slow. I might need to rasterize it! The human disturbance layer is great, too. I wonder about the data recency? I'm hoping watershedBC will be self-updating to the latest data in the catalogue for each of the inputs and not depend on another group to update layers.

I'm thinking of trying to make a flowchart of data inputs required for watershedBC ... Need some sort of high level planning meeting!

@Jhydromet I added the CEF Human Disturbance data to the app. It's nice ! I'm very curious what the update schedule will be. It's already 2 years out of date.. but nice to have so many datasets consolidated.

Just heard some context on the CEF data update frequency - They are aiming for annual or biannually, but apparently these datasets are so coarse that they don't necessarily have the resolution/quality that updates really impact the values significantly...

Apparently they are invested in improving these datasets but it might be a long haul.. Sounds like its safest to treat these as static datasets for the time being

bevingtona commented 6 months ago

Sounds interesting, I think the point here is to have a framework that can easily include new datasets and updates. For now, this is probably OK, and we can work on improving the visualization, and even have a little inset map of the CEF data?
