Glossary

Crop Ratio The aspect ratio applied when exporting a view. Determines the shape of the exported image (16:9, 4:3, 1:1, Letter, A4).

Dataset A named group of locations sharing a marker color, shape, and HQ color. Multiple datasets on one map enable visual differentiation between categories (e.g. "Portfolio" vs "Targets").

Focus Mode A map mode that isolates a single country or US state by masking everything else with a solid color. Produces clean, presentation-ready country maps.

Focus Theme A preset color scheme for Focus Mode that controls the mask, target country, and neighbor styling. Examples: Focus White, Focus Dark, Focus Slate Finance.

Geocoding The process of converting a place name (e.g. "New York") into geographic coordinates (lat/lon). pitchmappr uses Nominatim by default.

Hi-Res PNG An export option that re-renders the map at 2–4× native resolution using vector tile geometry. Produces genuinely sharper output, not an upscaled screenshot.

HQ (Headquarters) A special location type. Only one HQ per map. HQ locations can display with a distinct color and star shape.

Label Custom display text for a location on the map. Overrides the place name. Typically used for company names, deal codes, or abbreviations.

MapLibre GL JS The open-source map rendering library that powers pitchmappr's interactive map. Renders vector tiles using WebGL.

Mask In Focus Mode, the solid color layer that covers everything outside the selected country. Default is white. Becomes transparent when "Transparent background" is enabled for export.

Nominatim The free OpenStreetMap geocoding service. Rate limited to 1 request per second with a community-observed daily cap of ~2,500.

PMTiles A single-file archive format for map vector tiles. pitchmappr loads its base map from a PMTiles file hosted on Cloudflare R2.

Projection Export An advanced export mode that renders maps using cartographic projections (Albers, Lambert, etc.) via d3-geo instead of the standard Web Mercator view.

Protomaps An open-source project providing vector map tiles in the PMTiles format. The base map data source for pitchmappr.

Saved View A named snapshot of a map position (zoom, center) with a crop ratio. Views are the bridge between styling and exporting — each export targets a specific view.

Schema (Project) The version identifier for the project JSON format. Current version is v4. Older schemas (v3) are automatically migrated on load.

Vector Tiles Map data stored as geometric primitives (points, lines, polygons) rather than pre-rendered images. Enables layer toggling, color customization, and resolution-independent rendering.
