Urban Heatmap Abstract Poster Satellite Color Bands

Build urban heatmap abstract poster satellite color bands from dense bands of color suggesting traffic, buildings, and movement from above. Establish scale through dense bands of color suggesting traffic, buildings, and movement from above, then let color and material do separate jobs. thermal red, electric yellow, asphalt gray, and deep blue should shape the emotional read, while satellite grain, tiny grid artifacts, and softened urban edges gives the viewer a tactile reason to stay. Use map-like layering with pixel-soft transitions and contour blocks to connect the larger movement to the smaller surface details. Let texture support aerial thermal mapping rather than competing with the main shape. A strong city planning poster version will feel flexible for cropping while retaining aerial thermal mapping.
