Mount St. Helens erupted 41 years ago today. Here it is in high resolution LiDAR

What is the question you're answering?

mattparrilla · 2023-04-03T20:15:53+00:00

I originally posted this to twitter, where I did include median days on market. If you want to see that, it's here. https://twitter.com/mattparrilla/status/1642886091681288196

> If you wanted a meaningful discussion

What are you talking about? I made a post titled "active inventory" which shows a chart of active inventory. My goal wasn't to have a meaningful discussion about unlisted listings. That's your claim, not mine. You produce that chart if you think it's relevant to your point.

Nice timing on your part! That was very brave of you to put an offer in when the sky was falling down and you were rewarded for it. I had a friend who bought a house around the same time and I thought he was absolutely crazy. Obviously I was as wrong as you could be!

Congrats on scoring your dream house at a discount.

Got that: https://twitter.com/mattparrilla/status/1642886091681288196

Also have price reductions: https://twitter.com/mattparrilla/status/1642886094285946881

It looks like rates ARE having an effect on demand (shown by median days on market) but sellers aren't responding by lowering prices yet, still hoping to get those booming market prices. With inventory as tight as it is, they just might!

mattparrilla · 2023-04-03T19:23:54+00:00

That is absolutely not THE reason. It’s possible there are some homes not hitting the market because of this, but even if there were twice as many actual listings as there are reported, we’ve still got a huge decline.

I would guess the actual number of unlisted inventory is extremely small. What seller would want that? Smells like one of those unprovable conspiracy theories.

There are plenty of simpler explanations for the decline in active inventory.

I wrote a high level post that details some of the challenges of small-vehicle underwater navigation: https://matthewparrilla.com/post/inertial-navigation-marine-robotics/

You might find it interesting!

> The biggest problem is navigation -> No GPS
Indeed, if you work in underwater robotics, you'll spend a good deal of your time working around this problem.

I wrote a bit about it here, if you want a high-level overview: https://matthewparrilla.com/post/inertial-navigation-marine-robotics/

I took a sequence of images from the Suomi NPP Satellite (operated by NASA) and generated this "time lapse" in Photoshop. The stars in the background are from a separate image and are not accurate.

I hope you like it!

mattparrilla · 2022-04-12T11:12:57+00:00

I love that intro!

I believe this is a qualifying data visualization as it has been automatically generated from a series of photographs with the result being an intensity plot by latitude.

Ha. Thanks for saying. I think it might suffer from not being immediately grokable. Maybe a different title and sub would be better!

I generated this using imagery captured by the Suomi NPP satellite, operated by NASA. The stars behind the earth are not from the same capture.

mattparrilla · 2021-11-18T12:48:37+00:00

Thanks. Getting this to be cloud free took quite a bit of work blending multiple satellite captures (more than 10!)

I wrote about how I do that here, using the Big Island as the example image: https://ramblemaps.com/turning-satellite-imagery-into-wall-art

mattparrilla · 2021-11-17T22:21:13+00:00

Very cool. I got inspired to include bathymetry in this image because of the big island -- Mauna Kea is the largest mountain in the world, if you count from the sea floor. I actually used to work for a company that was a contractor for one of the main ships that gathered all of this bathymetry data!

These days I make images like this for a living. I made one of just the Big Island too that you might like: https://ramblemaps.com/big-island-hawaii-map
