🛰️Do you need very high-resolution imagery over a whole country or a large area for your mapping project? Then 21AT Basemaps / LAM (Large Area Mosaics) is perfect for the occasion! Since it's nearly cloudless, ortho-rectified, mosaicked, and color-balanced, this imagery is ready to go right out of the box for most countries in the world. Some key specs about 21AT Basemaps / LAM: ✅ Access to very high-resolution mosaics at up to 0.5m. ✅ Updated annually to incorporate new images and stay current. ✅ Color-balanced, nearly seamless ortho-photos. ✅ <5% minimum cloud coverage per image mosaic. ✅ 4 most common spectral bands available (blue, green, red, near-infrared). ℹ️ For info or a quote, visit Cloudeo Marketplace: https://lnkd.in/dU4waN_B #earthobservation #remotesensing #satelliteimagery #earthfromspace #cloudeomarketplace

Kohya Deep Shrink ComfyUI Node I was watching a You Tube video describing this recent node in ComfyUI. The immediate application was fast rendering of higher resolution images. Seemed great, especially for landscapes. It avoids repeating parts of the image as you request larger resolution without resorting to an upscaler model. Apparently it is an implementation of this paper, that does seem interesting. The summary I read said it worked by reducing the size in the image latent space during the image generation. https://lnkd.in/eR5Zmnkg

Penrose diagram. A Penrose diagram is a kind of spacetime diagram arranged to make clear the complete causal structure of any given geometry. They are an indispensable map for navigating inside a black hole. Roger Penrose, who invented this kind of diagram in the early 1950s, himself calls them conformal diagrams. In a Penrose diagram: Light rays move at 45o from the upward vertical; Points at infinity (at infinite distance, or in the infinite past or future) are contained in the diagram. https://lnkd.in/esCeJjNt

***A Question of Natural Space and Boundaries*** And why it's so vital to understand them properly What actually happens physically when two spheres of equal size (e.g. two water droplets) coalesce to form a single sphere of double the size - and why? And how is this related to the difference between natural geometry and abstract geometry? And between 'whole' numbers and actual numbers? https://lnkd.in/eRqGU65s #nature #naturalinclusion

Particle study #12: experimenting with stylistic transitions. In this case, we employed a scanning plate to emphasise the passage from one texture to the other. This technique mirrors the one employed in Luna Somnium, where the shift from one stylistic language to another defines distinct sections within the piece.

Day-21 of #100daysofCodingChallenge Today's problem was matrix Diagonal Sum in this we have to return the sum of primary and secondary diagonal but not including repeated primary Diagonal element Approach i)Primary Diagonal: The elements of the primary diagonal are located at mat[i][i] for i = 0 to n-1. We add these elements to the sum. ii)Secondary Diagonal: The elements of the secondary diagonal are located at mat[i][n - i - 1]. We add these elements to the sum as well. iii)Avoid Double Counting: In case of an odd-sized matrix, the center element is part of both diagonals. The condition if (i != n - i - 1) ensures that we don't count the center element twice.

Mapmakers, we’re back with more insider tips and tricks! 👀 Now that we’ve laid the groundwork for mapping your space, learn how to enrich your maps with finer details like labels, objects, descriptions, and images. Learn more about these helpful mapping techniques: https://hubs.li/Q02JPCB-0

Today is Day 12 of our julekalendar! What do you think this is an image of? The thing we showed yesterday does not belong anywhere near your risengrød but could be in your attic, as it shows a 3D image of a tiny part of the shaft of a birds feather. This tail feather is most likely originating from a common wood pigeon and the image collected with microCT allow us to visualise and investigate the small pores within the core of the shaft. Visualizing porosity is important in many different industries.

Day 593 of Daily LeetCode | 840. Magic Squares In Grid (Medium) https://lnkd.in/ecf75b6t The code defines a class Solution with two methods: numMagicSquaresInside to count the number of 3x3 magic squares in a grid, and is_valid_magic_square to check if a 3x3 sub-grid is a magic square. The code optimizes the checking of rows, columns, and diagonals by reducing redundancy and ensuring all checks are performed within a minimal vertical space.
