ISSN 0742-468XLayers are the backbone of any GIS platform, and Atlas is no different.
The way you organize layers can dramatically impact how useful your maps are. Poorly organized layers can confuse the viewer, while a well-structured layout makes your data clear and easy to interpret.
In this guide, we'll look at how to efficiently organize layers in Atlas, focusing on best practices, tips, and how to make the most out of the tools available.
What Are Layers?
In a GIS platform like Atlas, layers are the individual pieces of your map. Think of them as transparent sheets stacked on top of each other. Each layer holds specific data. For example, you might have one layer for roads, another for rivers, and another for population density. When combined, they create a complete picture of your geographic data.

Summary
Esri's Education team highlights the shift from desktop-centric GIS to web-based paradigms, emphasizing interactive, real-time maps over static PDFs or JPEGs. Desktop GIS remains vital for data management and advanced analysis, but web-based GIS enables dynamic, mobile-friendly maps with real-time updates and pop-ups. Students must learn to configure web applications, considering audience needs, accessibility, and UI/UX. Key skills include choosing appropriate app frameworks, customizing map layers, and controlling visibility and symbology by zoom level.
Esri's Arcade scripting language enhances interactivity by enabling dynamic pop-ups and joins. Understanding the tiers of web applications—apps, maps, and layers—is crucial for effective design. This shift demands teaching students to prioritize user interaction and iterative design for web-based GIS, moving beyond traditional print maps.

Life360 isn' fixing it fast enough
Summary
You've likely heard of Tile tags, those handy trackers for keys or bags. But researchers at Georgia Tech uncovered a dark side: Tile tags are easily abused by stalkers. They emit a static, unencrypted MAC address, trackable without alerts. Worse, Tile's “anti-theft mode” disables anti-stalking features, leaving users vulnerable. Life360, Tile's parent company, has known about these flaws since November but has offered only vague fixes. Unlike Apple's AirTags, which rotate IDs and alert users, Tile stores data in potentially accessible clear text.
To check for rogue Tiles, Android users can use the Tile app's Scan and Secure feature, though it's limited and misses anti-theft mode trackers. Experts recommend switching to safer options like Pebblebee and using services like Incogni to remove personal data from over 400 data broker sites.

I know you understand GIS, but I thought this might be handy to help others in your organization understand what it is you do
Summary
Geographic Information System (GIS) technology captures, stores, analyzes, and visualizes spatial data, linking location information with descriptive details to reveal patterns and trends through maps, charts, and 3D models.
Its core components—hardware, software, data, people, and methods—work together to process vast datasets, enabling real-time collaboration and decision-making. From urban planning to environmental management, GIS optimizes transportation, tracks disease outbreaks, and supports precision agriculture.
Benefits include enhanced decision-making, cost efficiency, and predictive capabilities through AI integration. As GIS evolves with Big Data and cloud computing, it powers smart cities and data-driven industries, transforming raw geographic data into actionable insights for sustainable planning and development.

In California, Pennsylvania, Washington and elsewhere, water districts are often turning to GIS and other tech tools to better serve their communities and the increasing needs of firefighting.
Summary
As climate change intensifies urban wildfire risks, water districts are taking on new fire protection roles, leveraging GIS, data, and hardware advancements. The Santa Margarita Water District (SMWD) in Orange County, Calif., has built three reservoirs holding 3 billion gallons of recycled water near wildlands to support firefighting. “You need water for day-to-day living, but we're also going to need it more to maintain community resiliency,” said Nate Adams, SMWD's director of water resiliency. These reservoirs, kept partially full, aided firefighting during the 2024 Airport Fire, supplying over 700,000 gallons.
SMWD manages 9,000 fire hydrants using Esri's GIS technology, which has grown more robust, enhancing asset management. Similarly, Pennsylvania's Hampton Shaler Water Authority upgraded to GIS dashboards, replacing paper-based systems with real-time tablet updates. Bellevue Utilities in Washington offers a customer portal with near-real-time water usage tracking, supported by smart meters and VertexOne software, alerting over 2,200 customers to leaks since its June launch.

The shutdown hobbled congressional activity on artificial intelligence legislation, a setback that could hinder the Trump administration' broader tech policy plans.
Summary
The ongoing government shutdown is delaying federal technology requirements, particularly AI policy, as experts predict legislative projects will be sidelined by larger bills. “The federal shutdown will affect a lot of ongoing and important legislative activity,” said Adam Thierer of the R Street Institute, noting delays in creating a national AI policy framework. Stalled bills include the National Defense Authorization Act (NDAA) and AI-focused proposals like Sen. Ted Cruz's AI sandbox and Sen. Josh Hawley's AI risk evaluation bill.
The NDAA, critical for AI adoption in the military, is expected to dominate Congress in 2026. Meanwhile, state legislatures like California and Colorado are advancing AI regulations, potentially creating a patchwork of policies if federal action lags, undermining President Trump's AI Action Plan.

With the mercenary spyware industry booming, Apple VP Ivan Kristić tells WIRED that the company is also offering bonuses that could bring the max total reward for iPhone exploits to $5 million.
Summary
Apple has increased its bug bounty program's maximum payout to $2 million for software exploit chains that could enable spyware, announced Ivan Kristić at Hexacon in Paris. This reflects the value of vulnerabilities in Apple's secure mobile environment. The program now offers up to $5 million for exploits bypassing Lockdown Mode or found in beta testing, effective next month.Kristić emphasized rewarding researchers for countering mercenary spyware.
With over 2.35 billion active devices, Apple's bug bounty, public since 2020, has paid over $35 million to 800+ researchers. New categories include WebKit and wireless proximity exploits, plus “Target Flags” for real-world testing. Apple also introduced Memory Integrity Enforcement in the iPhone 17 to protect vulnerable users, donating 1,000 devices to rights groups.

Microsoft ended automatic, free updates for Windows 10 users, potentially rendering millions of computers increasingly obsolete.
Summary
Microsoft ended free, automatic updates for Windows 10 on Oct. 14, 2025, affecting over 500 million users globally, urging them to upgrade to Windows 11. Without updates, computers remain functional but lack technical support, software updates, or security fixes, posing risks. Consumer advocates, like Jenn Engstrom from California Public Interest Research Group, estimate 400 million computers can't upgrade, potentially creating 1.6 billion tons of e-waste. They urge Microsoft to continue support to reduce environmental impact.
Peter Volin, a retiree from Albany, California, spent $1,500 on a new computer after his failed to meet Windows 11 requirements. While Microsoft offers a year of paid security updates, IT specialists like Vladimir Galant recommend upgrading for cybersecurity, comparing outdated systems to faulty equipment.

The plant's three 320-MW sections will together comprise a 960-MW plant within the space of a few city blocks, Amazon said.
Summary
The Cascade Advanced Energy Facility, funded by Amazon and built by Energy Northwest near Richland, Washington, will utilize 12 small modular reactors (SMRs) from X-energy, Amazon announced Thursday. The facility's modular design allows a 960-MW plant to fit within a few city blocks, unlike traditional nuclear plants requiring over a square mile. X-energy's Xe-100 reactor, backed by Amazon's $500 million investment, will power the initial 320-MW phase, expandable to 960 MW.
Construction is set to begin late this decade, with operations starting in the 2030s. The energy will support AI and digital tools. Energy Northwest highlighted the project's role in providing reliable, carbon-free energy. A collaboration with Korean partners aims to deploy over five gigawatts of Xe-100 reactors by 2039, mobilizing up to $50 billion in investments.
