On July 1, 2026, The Company Once Known As Maxar Began Selling 3D Maps Of Earth It Can Refresh Within A Day Or Sharpen To 15 Centimeters, Built Less For People To Study Than For The Autonomous Drones And Weapons That Navigate By Matching Their Cameras Against The Terrain
(Vantor, the American Earth-observation company… is now rebuilding chosen stretches of the planet as three-dimensional models and delivering them within a day of imaging — a commercial first…)

• “Built for GPS-denied warfare…
• The 3D twist changes the risk calculus…”
“Vantor, the American Earth-observation company…., is now rebuilding chosen stretches of the planet as three-dimensional models and delivering them within a day of imaging — a commercial first, the company says, and one aimed as much at autonomous machines as at the analysts and militaries who have always been its customers.
The service, called WorldView 3D, went live on July 1. It draws on a fleet of 10 satellites imaging Earth’s surface at 12-inch (30-centimeter) resolution, according to Space.com. The 3D views are constructed by combining multiple images taken from different orbital angles, then refreshed on a daily cadence — a speed the company says is impossible to match with aircraft or drones over remote or contested territory.
According to the company’s launch announcement… the service would enable rapid updates of remote and contested areas, calling it the future of spatial intelligence….
The product comes in two tiers…:
• Standard resolution delivers 20-inch (50 cm) imagery with 13-foot (4-meter) accuracy in all directions.
• The HD tier tightens that to 6-inch (15 cm) resolution with 10-foot (3-meter) positional accuracy in three dimensions.
Those numbers matter for a specific reason. Traditional 3D mapping — the kind used by autonomous vehicle companies and defense contractors — has historically relied on aircraft flights, drone surveys, or LiDAR passes. Those methods produce excellent detail. They also require physical access to the airspace above the target.
Vantor’s pitch is that satellites remove the access problem. A constellation in low Earth orbit passes over hostile territory as freely as it passes over Kansas…”

“Satellite imagery now documents systematic patterns of infrastructure destruction at spatial resolutions and temporal cadences that were unavailable during the atrocities of the twentieth century. Whether and how such data may enter bioethical deliberation, however, remains under-theorized. Quantitative remote sensing produces damage percentages, not normative claims, and bridging the two without committing an is-ought fallacy requires an explicit epistemological procedure. The contribution developed here is normative and epistemological rather than empirical. A six-component admissibility framework integrates, for the first time, geospatial evidence, population-level bioethical principlism, and the coherentist verification epistemology of political fact-checking into a single reproducible procedure for the bioethical use of satellite imagery. The first component specifies evidence admissibility criteria tailored to bioethical rather than strictly legal use. The second requires coherentist triangulation across methodologically independent remote sensing studies. The third operates as a bioethical relevance filter mapping infrastructure categories onto population-level social determinants of health. The fourth operationalizes principlism by translating health justice, accountability, solidarity, and sustainability into measurable geospatial observables. The fifth establishes ethical representation safeguards against voyeuristic or dehumanizing uses of destruction imagery. The sixth demands explicit epistemic humility regarding uncertainty, data missingness, and attribution limits. The Gaza conflict provides the case in point. Two independently produced geospatial studies, one based on SAR coherent change detection and one on very-high-resolution optical analysis, converge on extensive damage to civilian healthcare, water, sanitation, and educational infrastructure, and thereby satisfy the coherentist triangulation requirement of the framework. The resulting inference licenses bioethical claims of systematic survival infrastructure degradation while preserving transparent boundaries between what satellite evidence can and cannot establish about genocidal intent…”

I'm using changedetection.io to be alerted about new apartment units that are coming into the market at a complex I'm interested in. It is going pretty well.
Note that they offer a paying service, but if you are technically inclined you can run their software locally, like I do.
If you need to interact with the page (like I do), you can ask changedetection.io to start a selenium browser to check the page out.

Habe gerade #changedetection lokal auf der #Synology NAS installiert. Dort kann man wohl per #Apprise die Email Notifications einrichten. Ich stehe wir Ochs vorm Berg. Kennt jemand ein Tutorial zu Apprise für blutige Anfänger?

Je réfléchis à installer #changedetection (https://changedetection.io/) sur mon #raspberrypi mais je ne sais pas si il peut faire bon ménage avec le #pihole qui tourne déjà dessus à merveille…(docker n'y est pas installé)… une idée ?:) merci !!

Хе-хе, нарешті #changedetection.io буде приносити мені користь. Що 15хв перевірятиме вартість долара і сповіщатиме в чат. Наступне покращення - сповіщати тільки коли ціна досягне певного рівня.

My #caddy reverse proxy decided to randomly crash after I started using a #changedetection docker container. After a bit of detective work, I was able to identify the cause.
It turns out that the #systemd option LimitNProc is a potential footgun on hosts running containers:
Note that LimitNPROC= will limit the number of processes from one (real) UID and not the number of processes started (forked) by the service.

Any #flask gurus out there? Trying to wrap my head around seemingly HTTP spec-violating behaviour, together with the developer of #changedetection.
tl;dr: send_from_directory 304 responses have a body while they shouldn't

Change Detection in Angular seems to be a hot topic right now, so here are a couple of pointers I found useful:
- Angular Change Detection simplified (E-Book by @brechtbilliet registration needed): https://www.simplified.courses/free-angular-change-detection-simplified-e-book
- Out of bounds change detection (Segment in video by @mgechev): https://yewtu.be/watch?v=f8sA-i6gkGQ&t=6m3s
- Change detection runs in DOM order (Segment in video of ng-conf 2022; registration needed): https://vimeo.com/showcase/9897189/video/764349346#t=10m18s
