Consolidated Standardized Survey-Grade Checkpoints 3DEP 2010 to 2017 [USGS]

“One of the key aspects of 3DEP data is that data is verified by a collection of certified survey-grade GNSS checkpoints spread throughout each project. These points have always been available but were difficult to find and not standardized. [The USGS] have collated and standardized almost 42,000 of these checkpoints and are making them available for other uses. These points here in this first phase span from 2010-2017, but [the USGS] are in the process of making these available for all [their] projects, and hope to enable them in different ways in the future...”

Hello lazy web, a friend of mine fudged the NVRAM battery replacement in his Tektronix TDS644B.
One of those Dallas jobbies where you get to really tear into them to pry out the existing batteries.

So now the calibration is gone and the instrument is unhappy.
So what next? Finding some random calibration file and use that and hope for the best?
Maybe some of you know more.

I'm off to #iclr2023, Kigali

We'll present our work "beyond #calibration", discussing why it is important to control individual probabilities output by classifiers, and how to do it.
https://openreview.net/forum?id=6w1k-IixnL8

Our work enables to characterize whether a #classifier outputs class-probabilities that correspond to the fundamental uncertainty of the class given the data: P(y|X)

More important, I'll be around to meet people and discuss! Hit me up

Hi #Linux (#Debian / #Ubuntu) experts!

What do you suggest me to use in order to manage screen #calibration and #colors?

I bought a #ThinkPad without realizing that the #OLED #display is terribly itchy, and I would like to limit its exaggerated saturation.

See the thread I opened in #Lenovo #Community for more info.
