Analyze the input satellite imagery and general layout plan to generate an elevation analysis map, complying with the following requirements: ## 1. Overall Style Definition: National Geographic academic cartographic style Produce a **hybrid terrain map combining shaded relief and contour lines** based on satellite imagery and plan drawings. Render topographic volume through light-and-shadow simulation and contour delineation. Visual characteristics: a blend of vintage scientific aesthetics and modern technical precision. Adopt hypsometric tinting for base colors, paired with subtle surface textures. Layout specifications: strictly defined graticule (latitude/longitude grid) boundaries; a terrain profile diagram at the bottom; standardized scale bar and north arrow set. Professional terminology: - **Shaded Relief**: Terrain undulation represented by light and shadow effects. - **Contour Lines**: Equally spaced closed curves depicting variations in elevation. - **Spot Elevations**: Precise elevation labels at specific peaks or landmarks. - **Hypsometric Tinting**: Color coding to distinguish elevation ranges. ## 2. Breakdown of Detailed Elements & Hexadecimal Color Code Specifications ### 1. Terrain Representation Elements - Low elevation / vegetated zones: Soft light green gradients for valleys or plains. Color codes: `#BDD9A6`, `#A2C284` - High elevation / ridge zones: Dry earthy yellow or ochre tones for rocky cover or arid uplands. Color codes: `#D2B48C`, `#8B7355` - Extreme high elevation / glacial zones: Off-white for the highest areas. Color code: `#F5F5F5` - Water system: Alpine lakes and rivers rendered in clear pale blue. Color code: `#A6C9E2` ### 2. Linework & Annotation Elements - Contour lines: Ultra-fine dark brown lines; index contours thickened with numeric elevation labels. Color code: `#5D4037` (1px – 2px thin lines) - Core routes: High-saturation solid or dashed red lines as visual focal points. Color code: `#D32F2F` - Annotation font: Serif typefaces (e.g., Times New Roman or Adobe Caslon). Mountain names aligned along ridge orientation; water body names in italics. Color code: `#212121` (dark grey-black) ### 3. Auxiliary Analysis Elements - Terrain profile diagram: Positioned at the bottom of the map, showing elevation fluctuations along a designated path. - Spot elevation labels: Small markers marked with "x" or "+", with elevation values annotated alongside. - Latitude/longitude graticule: Ultra-fine black lines, with degree-minute-second labels along the margins.
