# SPECTRAL GRIDCORE // VECTOR PROJECTION ### Board-Approved Spectral Mode — Globe & Atlas *Extension of Standard Gridcore. Inherits all base constraints.* --- ## DESIGN PHILOSOPHY Spectral Gridcore is the data-encoding extension of Standard Gridcore. It applies the same structural wireframe language but introduces up to 7 additional color channels — each one carrying a discrete, non-redundant data dimension. The philosophical foundation is Edward Tufte: every mark must earn its place, and every color must encode real information. This connects directly to false-color remote sensing — Sentinel-2 band composites, LiDAR intensity returns, spectral indices — where color is measurement, not decoration. **The critical constraint:** If a color cannot be defined in a legend with a real-world value attached, it is removed. **Board provenance:** Tufte (data-ink ratio), Shannon (signal encoding), Rams (conditional necessity). Amber base channel approved by full Board under Standard Gridcore. Additional channels conditionally approved subject to declaration discipline. --- ## CORE SPECIFICATION ### Channel System - **Maximum 8 channels defined** per visual system - **Maximum 4 channels active** in any single image - **Amber (#FFB300) is always Channel 1** — the structural skeleton, always present, always dominant - Every additional channel must declare: variable encoded, value range or threshold, rendering element ### Channel Declaration Format ``` - [Color Name] ([Hex]) — [Variable] // [Value range or threshold] ``` ### Master Channel Palette *Phosphor-honest colors only. No pastels, no RGB primaries for decoration.* | Channel | Name | Hex | Canonical Use | |---|---|---|---| | 1 | Amber | #FFB300 | Base structure — always | | 2 | P1 Green | #33FF57 | Elevation / positive value / gain | | 3 | Cyan | #00FFFF | Flow / hydraulic / movement | | 4 | Red-Orange | #FF4500 | Anomaly / threshold breach / loss | | 5 | White | #FFFFFF | Critical annotation / divide | | 6 | Pale Blue | #AADDFF | Low confidence / atmospheric | | 7 | Magenta | #FF00FF | Classification boundary | | 8 | Yellow | #FFFF00 | Secondary anomaly / warning | ### Rendering Rules - Amber structural skeleton rendered first, always dominant - Data channels rendered as overlays — never replacing structure - Face fills: maximum 12% opacity per channel - Bloom on amber only — data channels are clean lines, no bloom - No two channels may occupy the same rendering element in the same image - All channels must remain legible against #000000 --- ## PROMPT TEMPLATE ``` SPECTRAL GRIDCORE // VECTOR PROJECTION SUBJECT: [Define the physical or logical system] CONTEXT TYPE: [terrain | industrial | network | isolated object] CHANNEL DECLARATION: - Amber (#FFB300) — [Base structure element] - [Color] ([Hex]) — [Variable] // [Value range] - [Color] ([Hex]) — [Variable] // [Value range] - [Color] ([Hex]) — [Variable] // [Value range] (Maximum 4 active channels. Unused slots removed.) CORE GEOMETRY: - Hollow wireframe skeleton — edges only - [Define primary structure elements] - [Define secondary structure elements] - Orthographic / isometric projection only ENVIRONMENT: - Absolute black void (#000000) - No horizon, no atmosphere LINE HIERARCHY: - Primary structure: dominant weight - Secondary structure: reduced weight - Context (contours/grid): thin - Data channel overlays: never heavier than primary structure CONDITIONAL OVERLAYS: - Contours: only if terrain context and real elevation intervals - H3 grid: only if spatial subdivision is meaningful - Face fills: maximum 12% opacity, data channels only - Remove all if irrelevant FLOW REPRESENTATION: - Major flows match primary structure weight - Minor flows match secondary structure weight - Uniform arrowhead style throughout - Color follows channel declaration - No text attached to arrows ANNOTATION: - Monospace labels only - Variables + coordinates only - Every label must connect via leader line - No narrative text - Bloom on amber only — data channel lines are clean FAIL CONDITIONS: - No perspective distortion - No gradients within any channel - No bloom on data channels - No color outside declared channels - No decorative UI/HUD elements - No fake status text - Amber structure must remain readable beneath all overlays - Maximum 4 active channels per image - No face fill exceeding 12% opacity ``` --- ## CONTEXT TYPE REFERENCE Inherited from Standard Gridcore. **terrain** — Elevation, surface, topographic character. Contour and H3 overlays eligible. **industrial** — Built infrastructure, structural integrity primary. Neither contour nor H3 typically relevant. **network** — Relational. Nodes and edges primary. H3 potentially relevant. **isolated object** — Single component in void. No overlays. --- ## WORKED PROMPT EXAMPLES ### Example A — GIS: Watershed Network Analysis ``` SPECTRAL GRIDCORE // VECTOR PROJECTION SUBJECT: Watershed drainage network, hierarchical stream order, arid terrain catchment CONTEXT TYPE: terrain CHANNEL DECLARATION: - Amber (#FFB300) — TIN terrain skeleton, catchment boundary edges - P1 Green (#33FF57) — First and second order streams // headwater channels - Cyan (#00FFFF) — Third and fourth order streams // main channel network - White (#FFFFFF) — Watershed divide // critical ridge breakline CORE GEOMETRY: Hollow wireframe TIN.

If the change is legible from two separate images — use two Standard images. ### Epoch System - **Amber (#FFB300) always encodes the most recent epoch** — dominant, full weight - Prior epochs rendered as ghost layers — same geometry, reduced opacity, declared color - **Maximum 3 epochs** per image - Every epoch must declare: date or period, opacity ### Epoch Palette | Epoch | Name | Hex | Opacity | |---|---|---|---| | Current | Amber | #FFB300 | 100% | | Prior | Pale Blue | #AADDFF | 35–45% | | Earliest | White | #FFFFFF | 15–25% | ### Change Channels *(optional — declare only if change is the subject)* - **Red-Orange (#FF4500)** — Loss geometry // structure absent in current epoch - **P1 Green (#33FF57)** — Gain geometry // structure absent in prior epoch - **Magenta (#FF00FF)** — Change boundary // perimeter of structural difference - Maximum 2 change channels active alongside epoch layers - Ghost epoch count + change channel count must not exceed 4 total active channels ### Rendering Rules - Ghost epochs rendered beneath amber — never obscuring current structure - Bloom on amber epoch only — ghost layers are clean lines, no bloom - No face fill on ghost layers - No gradient transitions between epoch layers ### Temporal Prompt Template ``` SPECTRAL GRIDCORE // VECTOR PROJECTION // TEMPORAL SUBJECT: [Define the physical or logical system and the nature of its change] CONTEXT TYPE: [terrain | industrial | network | isolated object] EPOCH DECLARATION: - Amber (#FFB300) — Current epoch // [Date or period] // 100% - Pale Blue (#AADDFF) — Prior epoch // [Date or period] // 40% - White (#FFFFFF) — Earliest epoch // [Date or period] // 20% (Remove unused epoch slots. Minimum 2 epochs required.) CHANGE CHANNELS (optional — declare only if change is the subject): - [Color] ([Hex]) — [Loss or Gain] // [What changed] (Maximum 2 change channels. Remove if not needed.) CORE GEOMETRY: - Hollow wireframe skeleton — edges only - [Define primary structure elements] - Ghost epoch geometry matches current epoch topology — same elements, reduced presence - Orthographic / isometric projection only ENVIRONMENT: - Absolute black void (#000000) - No horizon, no atmosphere LINE HIERARCHY: - Primary structure (current): dominant weight - Secondary structure (current): reduced weight - Ghost layers: proportionally reduced - Change channels: never heavier than primary structure ANNOTATION: - Monospace epoch labels at structural reference points - Date or period label per epoch — no narrative text - Every label must connect via leader line - Bloom on amber annotation only FAIL CONDITIONS: - No perspective distortion - No gradients within any epoch layer - No bloom on ghost layers - No color outside declared epochs and change channels - No decorative UI/HUD elements - Amber current epoch dominant and readable - Maximum 3 epochs per image - Ghost opacity not exceeding 45% - No face fill on ghost layers - Total active layers (ghost epochs + change channels) not exceeding 4 ``` ### Example — Terrain: Coastal Erosion ``` SPECTRAL GRIDCORE // VECTOR PROJECTION // TEMPORAL SUBJECT: Coastal bluff geometry — shoreline recession across three survey epochs, erosion face and cliff-top edge migration CONTEXT TYPE: terrain EPOCH DECLARATION: - Amber (#FFB300) — Current epoch // 2024 survey // 100% - Pale Blue (#AADDFF) — Prior epoch // 2014 survey // 40% - White (#FFFFFF) — Earliest epoch // 2004 survey // 20% CHANGE CHANNELS: - Red-Orange (#FF4500) — Loss geometry // eroded bluff face, recession zone CORE GEOMETRY: Hollow wireframe cliff profile. Bluff edge and erosion face as primary structure per epoch. Ghost epochs render same cliff geometry at declared opacity — recession visible as spatial offset between amber and ghost edges. Red-orange loss geometry as sparse wireframe infill between earliest and current edge positions — no solid fill. ENVIRONMENT: Absolute black void (#000000). No horizon. PROJECTION: Orthographic isometric, oblique view to show cliff face. ANNOTATION: Monospace year labels (2004, 2014, 2024) at bluff edge reference points. Recession distance coordinate between earliest and current edge. Leader lines only.
