#gischat Any Eduard shaded relief users out there? I seem to recall on older versions I could export the filtered DEM (not the SR) to be used in other apps. Now all I can find is the SR export and export grid which just gives you the original grid file, no filtering applied.
Meanwhile, this animated map explores the elevation at birth of every athlete who has earned a gold medal in the Winter Olympics. It uses data from Olympedia and Esri’s World Elevation Service to track birthplace elevations across athletes in 8 categories. #gischat

A Joy Plot Map of elevation and population for Colorado. Each line shows the rising and falling value of either population or surface elevation.
Colorado Pop x Elev Joy Plot
We can see a pretty good relationship between elevation and population density in CO. Even though the Rockies and high plains cover some of the small cities and towns. I may add an offset or extra VE point for the population layer.

Figure 13: Based on the proposed method, operators can dynamically view matching results from different positions and perspectives. Panel a) shows a long-distance perspective with a person in military-style clothing holding a tablet device outdoors on dusty terrain, with another person visible in the background. Panel b) displays a close-range perspective with hands holding a tablet under a concrete bridge structure, showing the device screen displaying augmented reality content aligned with the physical surroundings. Panel c) presents actual screenshots of geo-matching results featuring a 3D yellow wireframe model of bridge infrastructure overlaid on a photograph of gray concrete bridge support columns and beams, with text reading 'After geo-matching of bridge' at the bottom of the overlay.
Figure 15: Interactive spatial perception in outdoor mobile augmented reality (MAR). At approximately 40 meters from the building, users assess the alignment between virtual and real structures and query semantic attributes. Panel a) shows accurate alignment in position and orientation, displaying an aerial/top-down view of a white building with blue-tinted windows and a 3D model overlay. Panel b) shows GIS slicing revealing full indoor semantics, with a ground-level view of the building facade overlaid with numerous colored geometric icons (purple diamonds, orange hexagons, green squares, blue circles) representing different semantic attributes throughout all floors. Panel c) displays fourth-floor attributes including offices, restaurant, and restrooms, showing the same building view with fewer colored icons concentrated on specific floors. Panel d) presents first-floor attributes including meeting rooms, restrooms, and mother-and-baby room, with blue and green icons visible primarily on the lower portion of the building. Yellow flowers are visible in the foreground of panels b), c), and d), with palm trees and additional buildings visible in the background.

In Figure 13 below: a) Best energy efficiency; b) best user preference; c) best visual quality; d) e) closest to ideal point; f) optimal solution. Figure 13 showing six different cartographic styling variations of the same urban area map. Each panel a) through f) displays an identical street network with yellow/orange/brown road lines overlaying land parcels in various colors including green spaces (parks), blue water bodies, and urban blocks in pink, purple, cyan, and other hues. Panel a) features a dark teal/navy background with bright contrasting colors. Panel b) shows an olive/brown background with softer tones. Panel c) has a light beige/cream background with pastel colors. Panels d), e), and f) all use black backgrounds with progressively different color palettes: d) uses yellow streets with bright multi-colored parcels, e) employs pink/magenta streets with rainbow-hued parcels, and f) features green streets with a cyan-green-red color scheme. The maps demonstrate different approaches to urban cartographic design and color theory while maintaining the same geographic information.

A map showing the population and elevations of North Carolina using the Joy Plot style.
Now that I have a working model in QGIS for my Joy Plot workflow, I can focus on refining the maps. I have been interested in mapping elevation and populations for a long time, but I have struggled to find a method that shows both variables evenly. Joy Plots look promising.

#GISChat AGOL Pet Peeves: I would like to select the attributes I want to see when looking at the content in my AGOL account. Modified date is useful but not always relevant. I would just liked to be able to change that attribute from Modified to Created Date.
✨ Raster/grid logic is rather simple: six numbers define a grid, and from them you can compute cells, coordinates, cropping, snapping, etc.
All of this is explain in a blog post by Michael Sumner.
