🌟 Article of the Week 🌟 This week’s featured article from IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing (J-STARS) highlights advances in deep learning for multitemporal remote sensing image change detection. 🔍 This Week’s Highlight Title: B2CNet: A Progressive Change Boundary-to-Center Refinement Network for Multitemporal Remote Sensing Images Change Detection Authors: Zhiqi Zhang, Liyang Bao, Shao Xiang, Guangqi Xie, Rong Gao 📖 🛰️ In this article, the authors propose B2CNet, a progressive change detection network guided by change boundary awareness and a boundary-to-center refinement strategy. The network enhances fine-grained boundary detection and improves internal region consistency by integrating boundary-aware modules and bitemporal feature aggregation, leading to more accurate change detection in multitemporal remote sensing images. 🔗 Read the full paper here: doi.org/10.1109/JSTARS.2024.… Stay tuned for more groundbreaking research every week as we celebrate excellence in geoscience and remote sensing! 🌍📡 #IEEEGRSS #RemoteSensing #Geoscience #ChangeDetection #DeepLearning #JSTARS #ieeexplore #AOTW

🔥 OnPush is now the DEFAULT change detection strategy Components with no changeDetection set are now OnPush automatically. Want the old behavior? Set ChangeDetectionStrategy.Eager (there's a migration for it). ✍️ Signal Forms graduated to the public API! No longer experimental 🎉 You also get: - reloadValidation() - debounce on validateAsync/validateHttp - FieldState.getError() - template reactive FVC support 🌐 FetchBackend is now the default for HttpClient withFetch is deprecated → just remove it. ⚠️ Need upload progress? Use provideHttpClient(withXhr). Also: reportProgress → split into reportUploadProgress & reportDownloadProgress 💧 Incremental hydration is now the default behavior. No extra config needed. 🤖 Angular is going all-in on AI/MCP tooling: - provideWebMcpTools - declareWebMcpTool (experimental) - AI runtime debugging tools - an in-page Angular DI graph AI tool ✨ New core goodies: - @Service decorator (stable) - injectAsync() helper - debouncing signals - resource caching for SSR - bootstrap apps under shadow roots - TestBed.getLastFixture() 🧹 Big cleanup (breaking): - ComponentFactory / ComponentFactoryResolver → gone - createNgModuleRef → createNgModule - checkNoChanges → removed - provideRoutes → provideRouter - Hammer.js integration → removed ⚙️ Version requirements: - Node.js 26 supported - TypeScript 5.9 dropped - Minimum TS is now 6.0 🧭 Router changes: - paramsInheritanceStrategy now defaults to 'always' currentSnapshot in CanMatchFn is now required - new browserUrl input on router links That's Angular v22 in a nutshell 🎯

The biggest hurdle for satellite data in Latin America isn’t the technology; it’s institutional readiness. Spotting illegal mining or forest degradation through the clouds within hours is a massive leap forward. But to truly protect these resources, agencies must have the workflows, licenses, and authority to act on the data immediately. In the latest Scenes and Signals piece, Tata Lacale Canal, Synspective's Latin America lead, explores how the region is moving past the pilot phase and building the infrastructure needed to turn SAR from a crisis tool into an everyday operational layer.

ChangeDetection.io is already great at noticing web changes. changedetection-mcp makes those changes usable inside an agent workflow. Monitor pages, summarise diffs, route alerts, kick off follow-up actions. cc @Teknium Repo: github.com/rusty4444/changed…

I’ve been building small MCP servers for self-hosted tools that agents should already understand. First up: changedetection-mcp for @change_det_io. It lets Hermes or any MCP client create watches, check history, and ask what changed without opening the UI.

📢 CA-MTransUNet: Cloud-Aware Mixture-of-Experts Linear Transformer U-Net for forest burned area (FBA) mapping using Sentinel-1 and Sentinel-2 images by Sahand Tahermanesh, Ali Jamali @ali_jamali86, Armin Moghimi @ArminMoghimi2, Amin Mohsenifar, Ehsan Khankeshizadeh & Ali Mohammadzadeh 👉 doi.org/10.1080/20964471.202… 💌 This study addresses the limitations of existing #forest #burnedarea detection (#FBA) approaches, which are constrained by challenges in multimodal #dataintegration, the high computational complexity of attention mechanisms, and #cloudcontamination in optical satellite imagery. To overcome these issues, it proposes a Cloud-Aware Mixture-of-Experts Linear Transformer #UNet that integrates #Sentinel1 #SAR and #Sentinel2 #opticaldata through dynamic weighting and an efficient MoE-based linear attention framework. The model achieves superior segmentation accuracy and faster inference compared with several state-of-the-art architectures, while remaining subject to higher memory demand and occasional misclassification of water bodies, highlighting areas for further optimization in operational #wildfire monitoring. #Deeplearning #remotesensing #GIS #dataanalysis #BigData #forestfire #machinelearning #changedetection #ecologicalmonitoring

🚦💥𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗯𝗲𝘁𝘄𝗲𝗲𝗻 𝗗𝗲𝗳𝗮𝘂𝗹𝘁 𝗖𝗵𝗮𝗻𝗴𝗲 𝗗𝗲𝘁𝗲𝗰𝘁𝗶𝗼𝗻 𝗮𝗻𝗱 𝗢𝗻𝗣𝘂𝘀𝗵 𝗶𝗻 𝗮 𝟭𝟬𝟬% 𝘀𝗶𝗴𝗻𝗮𝗹𝘀-𝗯𝗮𝘀𝗲𝗱 𝗭𝗼𝗻𝗲𝗹𝗲𝘀𝘀 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻? In practice, no meaningful difference. But still very interesting to know why: 𝗛𝗼𝘄 𝘀𝗶𝗴𝗻𝗮𝗹𝘀 𝗱𝗿𝗶𝘃𝗲 𝗰𝗵𝗮𝗻𝗴𝗲 𝗱𝗲𝘁𝗲𝗰𝘁𝗶𝗼𝗻 When a signal is read in a template, Angular's reactive graph records that dependency. When the signal updates, Angular internally calls markForCheck() on that component — regardless of its change detection strategy. Both Default and OnPush get marked dirty and re-rendered by the same mechanism. 𝗪𝗵𝗮𝘁 𝗢𝗻𝗣𝘂𝘀𝗵 𝘄𝗮𝘀 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝘀𝗼𝗹𝘃𝗶𝗻𝗴 OnPush was designed to opt out of the Zone.js-driven "check everything" cycle. Without it, Zone.js would patch every setTimeout, Promise, XHR, etc. and trigger a full top-down tree walk. OnPush let you say "only check me if my inputs changed or Iwas explicitly marked dirty." In a zoneless app, that problem doesn't exist. There is no global tick. Either: 1 - A signal marks a component dirty 2 - Or you mark the component has dirty yourself explicitly Notice that the async pipe will also mark the component as dirty, but here I'm assuming a signals-only app. In a signal-based zoneless app, there's no runaway Zone.js cycle to protect against. 𝗪𝗵𝗮𝘁 𝗵𝗮𝗽𝗽𝗲𝗻𝘀 𝗶𝗳 𝘀𝗶𝗴𝗻𝗮𝗹𝘀 𝗮𝗿𝗲 𝗯𝘆𝗽𝗮𝘀𝘀𝗲𝗱 In this exact type of application, if you accidentally bypass signals — a direct property mutation, a class field updated without signal.set(), etc. — nothing happens. This hold true for both Default and OnPush - again this is true for a zoneless application specifically. In a disciplined signals-only codebase that's actually a non-issue - every data modification goes via a signal. 𝗔𝗻𝗴𝘂𝗹𝗮𝗿'𝘀 𝗱𝗶𝗿𝗲𝗰𝘁𝗶𝗼𝗻 In the long term, it looks like fine-grained signal reactivity replaces the more coarse-grained Default/OnPush distinction entirely. The more concrete near-term step is github.com/angular/angular/d…, which proposes making OnPush the schematic default in Angular 22 — because in a signals-first world, Default becomes the odd choice rather than OnPush. #angular #angular21 #angular22 #onpush #changedetection

Desperately want to remove needing to add “changeDetection: ChangeDetectionStrategy.OnPush” in apps which are entirely new, Zoneless and Signals-based - would love to be able to set the “default” to OnPush in the same way “standalone: true” did.

Sixteen imagers. Twenty-two bands. Daily global coverage. What does it actually take to build a science-grade measurement system in orbit? Our latest piece in @SpaceNews_Inc breaks down the engineering behind @EarthDailyA #constellation — calibration, thermal stability, ground architecture, and why we release data as a quality milestone, not a pixel milestone. 👉Click to read: hubs.li/Q044bxJq0 #EarthObservation #SpaceEngineering #ChangeDetection
