Anyone know what part of the NEOC Blue Hills map has been affected by the May Day brush fire?

Looks like it shows up here, not sure if that is the full extent:

That appears to be an area (relatively small) that was mapped as dark green, so maybe that's good news. That place could use more ground fire, honestly.

I have never set a control in that area....lots of scrub oak up there typically.

Coach: you will probably be able to set controls in there now. In Florida my experience is that the best time to set controls in scrub oak areas is in the two years after a 'prescribed burn'. You might get a few more years in MA.

Might not be any field checking in there, though. Work to do.

What you really need is to suggest that some authority schedule and pay for a custom lidar scan flight ("to assess the damage"), this would provide far better contours than you've probably been able to get at any previous point in time.

Terje, The LiDAR they have available is from 2013-14 and done to assess damage from another disaster, that time a hurricane.
This is a 20 minute look at what the LiDAR already freely available can produce I did not bother with slope gradients and figured extracting the vegetation would be not relevant.

@gordhun: It looks like that area has limited rock outcrops, i.e. pretty old landscape?

I should really take advantage of the LIDAR, as I am the main person doing mapping in the Blue Hills (for each year's Blue Hills Traverse).

@coach, Reach out if you would like some assistance re: lidar.

Quick map made with OOM, OSM data+ KP output. 5m + formlines just like in gordhun's map. I guess the input data was the same, so differences are for using different apps.
