Data from Floating Forests for YOU!

The day has come – we’re finalizing our data pipeline to return data to you, our citizen scientists! It’s been a twisty road, and we’re still tweaking, but we’ve begun to build some usable products for your delecation and exploration!

We want to know more from **you** about what you want and what is interesting for you to explore, so, today, I’m going to post some demo data for you to look at and give us feedback and comments on. This is a data file from our California project that consists of polygons for each kelp forest at different levels of user agreement on whether pixels are kelp or not. So, first, here’s the file in three formats (depending on what you want) (we can also add more if asked for)

SQLite Lat/Long Projection
RDS (native R format) Lat/Long Projection
RDS (native R format) UTM Projection (Zone 10)

You can do a lot with these in whatever GIS software is your preference, and if anyone has examples, we’d love to post them! For now, here’s a quick and dirty visualization of the whole shebang at the 6 users agreeing on a pixel per threshold (source.

Neat, huh? You can even see where something in one image was confusing (no kelp on land!) which now I’m *very* curious about.

So, what’s in this dataset? There’s a lot, but here are things most relevant to you

threshold – the number of users who agree on the pixels in a given polygon are kelp
zooniverse_id – the subject (i.e., tile) id of a given image, if you want to just look at a single image, subset to that id
scene – Individual Landsat “images” are called scenes. So, every subject that we served to users was carved out of a scene. You can look at a whole scene by subsetting on this column. For more about what a scene name means, see here
classification_count – number of users who looked at a given subject
image_url – to pull up the subject as seen on Floating Forests
scene_timestamp – when was an image taken by the satellite?
activated_at – when did we post this to Floating Forests?

There’s a lot of other info regarding subject corner geospatial locations. We might or might not trim this out in future versions, although for now it helps us locate missing data and see what has actually been sampled.

So, take a gander, enjoy, and if you have any comments, fire them off to us! This is just a sample, and there’s more to come!
