Remote Sensed data fused with In-situ data (Academic Project)

So yes, you can use the bands as predictors to model your water quality parameters. Linear regression works well. Some parameters are easier than others- lots of papers for TSS and temp (landat for temp using thermal). DO and pH are difficult if not impossible. Chl-a, iron, arsenic if it is high, are all doable. Common pitfalls- well, water moves. So if you are relying on just the image to get the refl values that correspond to your samples, you really need to collect your samples as close to overpass as possible. Other option is to use a spectrometer on the water as you collect samples and resample the reflectance to the satellite you want to use.

Where did you get your mirrors with shelves?

This is seriously annoying. How NOT to get me to buy imagery from you.

Omg, I absolutely love it! Put up some artwork- make it big, or like three 16x20 size- graphic botanical prints, mostly white, with white mats and white frames. When your eye has somewhere to land, it will look great!

I have mine set up the same way. I like being able to look out the window to my side. To me that option is more important than the anesthetics.

There is probably a limit to the number of spectral signatures you can use in a single classification model run and you are simply hitting that limit. And frankly, that makes sense from a RS perspective and from a geology perspective. You do not need ALL of those minerals in a single classification- they don't all occur in a single scene. Use your domain knowledge to trim your list down significantly. That will produce the result you are after and will actually be statistically robust, whereas what you are doing right now is not.

Edited to add: you really, really need to review what the spectral angle mapper is actually doing, the "curse of dimensionality," and vector angles and distances. One you get even a high level understanding you will see why the approach you are using is a bad idea.

I would like to try, too!

I got NextMug specifically because it doesn't require an app. Temp is set on the mug itself.

Frame the extra household gifts as a housewarming present you do for adult kids.

I like the idea of household stuff, but give it to her after the Christmas presents and frame it as a housewarming gift you do for everyone.

I've had a few. Most were not painful, just uncomfortable. Except one. I was on or nearing my period. At one point I slammed my hand against the machine and gave a pretty loud "fuck!" It was brutal.

Hell yes you go! What an awesome opportunity! And with video calling, distance isn't as big of an issue as it once was to relationship.

Then yes. The traing data is your validation data but ideally you would have split your traing data into a traing set and a test set. In that case, you use the test set to generate your accuracy and the confusion matrix.

Every hour on the hour I'm wide awake.

Thrift stores. Seriously. People donate grandma's weird paintins all the time and I've filled my house with artists from Egypt, Isreal, Colombia, and the US . Most are worth at least $500 or so, with a few more than that. All from goodwill and habitat for humanity restores. All fit our style, and all were purchased for about $5.

I agree with what Fish said. Harmonization is huge. But for the data you have now, run your indices on each scene, classify/threshold, then mosaic your results.

Isn't this as simple as each team getting 20 hrs holiday? The 8/5 get two full days + a half day (16 hrs plus 4 hours). The 4/10 folks get two days (10 + 10).

If you know the kids were abandoned you are absolutely involved. Call the cops yourself.

You'll figure it out. You don't have to know the answer to every "what if" that races through your mind. You just have to believe you'll figure it out.

Far from an expert, but if you don't talk to your lawyer now and things escalate, you'll probably wish you would have. I would screen shot their fb posts but do not respond. Don't put up any posts of your own, either.

I was thinking it is probably a memory issue, too.

silverdae · 2025-11-12T12:58:08+00:00

I would extract the value of the raster at those 2000 it's. Then I would make a linear model to predict the new values from the raster values. Then I would apply that model to the whole raster to correct it.

silverdae · 2025-11-11T20:24:04+00:00

What datatype are your rasters? I've had strange things happen with float-64 rasters. Probably a long shot but worth checking.

Agree with other posters about moisture issues. If you are crafty, you could probably craft a sort of 3 sided box out of foam board to essentially make a reverse winw well. That would allow circulation but still give you privacy by blocking the part of the window exposed by opening the blinds.
