#2That pink/blue distinction is really hard to visually nail down. Is the Southeast US gaining or losing coverage?

i zoomed into some land that i'm intimately familiar with in mississippi. it got the tree loss right (when some logging took place), but doesn't show the later reforesting.

It has a tooltip on the loss section that mentions that the young trees need to get big enough to 'achieve canopy closure'

I know it's not really difficult, but just reading it spelled out like that makes it sound very non-intuitively difficult. Tech writing is hard!

Looking in the area of the map East Texas and eastward toward the east coast, there is a definite blue tinge showing indicating gains in that area. Using the slider to narrow the range makes it even more clear.
I wonder if this is gains from natural regrowth or reforestation efforts like you describe. I was pleasantly surprised to see any positive direction on the map as I have a seeminly pessimistic view on the situation.

It helps if you remove the Green layer and zoom in (otherwise it just looks purple).

#10Cool to see this on HN - this is a product from the World Resources Institute[0] (my employer). I can potentially relay some knowledge from that team or try to direct someone here for questions and comments. The important thing to know for these maps is that Tree Cover Loss is not directly "deforestation". On a pixel by pixel basis (each covering ~30m x 30m) tree loss can occur without the major ecosystem destruction of deforestation. This is still measureable. That is why the visualization of tree cover loss is parameterized by percentage for greater inspection and nuance.
I will take this opportunity to point out the joy and satisfaction that comes along with making these kind of data for impact products. We get to work on globally critical problems, making real measured impact, solving interesting technical problems, and developing features and tools for real and appreciative users across the world. We have dedicated and talented staff (product and engineering teams, in addition to tons of researchers and engagement staff) who are passionate about their work and our collective mission. It's a great environment to work in each and every day. There are always challenges - project/institutional revenue is driven mainly by grants, our salary can not compete with the cash+equity offers of big SV tech companies and VC backed startups. But when I wake up in the morning and come to work (we are a very distributed/remote organization) I know that the time and effort I spend is directed towards a global good and I can easily say the same for almost all of my colleagues. That is invaluable.
If this kind of work interests you feel free to reach out to me (email in profile). We frequently have job openings[1] for PMs, SWEs, and many technical roles.
Edit: Senior Software Engineer position currently open (and would be working on Global Forest Watch) [2].
