Google Maps’ satellite images reveal the full scope of Russian military assets

Posted by in categories: mapping, military

The world seems to have taken notice of the level of details services like Google Maps offer on an everyday basis. A Twitter account supporting the Ukrainian forces recently shared some images of Russian military establishments that were in public view on Google Maps.

⚡️GOOGLE MAPS ВІДКРИВ ДОСТУП ДО ВІЙСЬКОВИХ ТА СТРАТЕГІЧНИХ ОБ’ЄКТІВ РОСІЇ. Тепер кожен може побачити різноманітні російські пускові установки, шахти міжконтинентальних балістичних ракет, командні пункти та секретні полігони з роздільною здатністю близько до 5 метра на піксель. pic.twitter.com/i75wR8Efwo — Armed Forces 🇺🇦 (@ArmedForcesUkr) April 18, 2022

As the caption reads, Google has opened access to Russian military and strategic facilities. The tweet was probably an attempt at virtue signaling that Google had taken a stance against Russian aggression. However, as a Google spokesperson told The Verge, the information was available in the public domain well before the Ukraine conflict.

A Single Memory Is Stored Across Many Connected Brain Regions

Posted by in categories: mapping, neuroscience

Summary: Brain mapping study reveals memory engrams are widely distributed throughout the brain, including among regions not previously realized.

Source: picower institute for learning and memory.

A new study by scientists at The Picower Institute for Learning and Memory at MIT provides the most comprehensive and rigorous evidence yet that the mammalian brain stores a single memory across a widely distributed, functionally connected complex spanning many brain regions, rather than in just one or even a few places.

Texture Map GCode Directly In Blender With NozzleBoss

Posted by in categories: cybercrime/malcode, mapping

We’ve seen this funky dual disk polar printer already recently, but [Heinz Loepmeier] has been busy working on it, so here’s an update. The primary focus here is nozzleboss, a blender plugin which enables the surface textures of already sliced objects to be manipulated. The idea is to read in the gcode for the object, and convert it to an internal mesh representation that blender needs in order to function. From there the desired textures can be applied to the surfaces for subsequent stages to operate upon. One trick that nozzleboss can do is to create weight maps to tweak the extrusion flow rate or print velocity value according to the pixel value at the surface — such ‘velocity painting’ can produce some very subtle surface effects on previously featureless faces. Another

Emesent launches Hovermap ST autonomous drone LiDAR mapping and surveying payload

Posted by in categories: drones, mapping, robotics/AI

Autonomous drone mapping startup Emesent has announced its latest survey-grade LiDAR payload: Hovermap ST. The lightweight, IP65-rated solution is being launched with Emesent’s new Automated Ground Control feature that, the company stresses, enables autonomous data capture in harsher environments than ever and for a wider range of use cases.

Emesent’s LiDAR payloads leverage a process called simultaneous localization and mapping (SLAM), in which a drone builds a map and, at the same time, localizes the drone in that map.

New model may improve Bay Area seismic hazard maps

Posted by in categories: chemistry, mapping

The Santa Cruz Mountains define the geography of the Bay Area south of San Francisco, protecting the peninsula from the Pacific Ocean’s cold marine layer and forming the region’s notorious microclimates. The range also represents the perils of living in Silicon Valley: earthquakes along the San Andreas fault.

In bursts that last seconds to minutes, earthquakes have moved the region’s surface meters at a time. But researchers have never been able to reconcile the quick release of the Earth’s stress and the bending of the Earth’s crust over years with the formation of mountain ranges over millions of years. Now, by combining geological, geophysical, geochemical and , geologists have created a 3D tectonic model that resolves these timescales.

The research, which appears in Science Advances Feb. 25, reveals that more mountain building happens in the period between along the San Andreas Fault, rather than during the quakes themselves. The findings may be used to improve local seismic hazard maps.
