​You likely checked but the state may have good aerial maps on line. The province does here. Better res than other sites.

Terraserver has interesting data. They have rolling image dates with multiple sets per year. You have to pay for full access but signing up gives free overviews. I checked today for 2015 snow time aerials but they seem to restrict the freebies to the last two years. I was hoping to find canopy gaps.

Windows maps on win 10 has good features or did.

I just clued into Apple maps the other day. I don't know what they are like. I think they had a 3d option.

That bog island on GE and Bing looks real good.

I am wondering if there are chestnuts hidden in the dacks especially since southern sections have uncut areas.

" NOTE: Beginning in 2008, ALL imagery is 4-band orthoimagery, capable of both natural color and color infrared display. The base product was 1 ft resolution in urban areas and 2 ft resolution in non-urban areas through 2013. From 2014 on, the base product is 1 ft resolution for all areas."

Not too bad

The 2003 infrareds(?) are kinda cool. The conifer really shows up. ... &p=1723709

Too bad, I didn't have this here. ... verage.pdf

Lidar coverage?

There is a subculture of deer hunters in the dacks that get deep in. I wonder what they are seeing. A boots on the ground resource, maybe.

In regard to comments on Black Cherry variability, I think Black Cherry is a good example of a tree species with two personalities. When it grows in disturbed areas it acts like a poor quality invasive, when it grows in stable mixed-age relatively undisturbed forest it behaves like the magnificent forest tree it can be.

Thanks for the links, Lucas. That infrared image set is really interesting. I agree about the bog island- that continues to be the most intriguing spot to me. I may have a chance to drop into it soon. Unfortunately, how to use the LIDAR sets for NY continues to elude me. As a non-GIS-trained person I can manage with the PA LIDAR stuff, but the NY stuff is a little harder to interpret.

I think Elijah might qualify as one of those deep-woods dacks deer hunters, and he certainly has been the best guy on the ground covering the adirondacks lately. I lucked out joining in on this expedition, but Elijah's been doing a lot of groundwork.

I am surprised that so little is conifer woods. ... dirondacks


So let's start with the Adirondack Park Agency's Maps and GIS page, which includes maps, spatial data, statistics and publications.

SUNY-ESF's Adirondack Ecological Center uses GIS in a number of their research projects, detailed here with some nice detail of Unit Management Plans.

Maybe different imagery.
