Network Groundstations implementation notes

Documentation index · Generation pipeline

Status and scope

network-groundstations is a standard, default-rendered pass drawing the alpha60 Starlink gateway/POP records in every projection. Its checked-in input lives in assets.static/network-groundstations, so ordinary generation does not need network access.

The dataset is the alpha60 starlink-global-gateways-pops.20250902 snapshot (618 records) from bdekoz/alpha60-data, vendored with its SHA-256 pin. Each record is either a gateway Point or a gateway-to-POP LineString; the first coordinate of each record is rendered as the groundstation mark.

Default rendering

The pass follows the alpha60 Starlink gateway style:

The legend states NETWORK GROUNDSTATIONS / <datestamp> and the record count. All products use the Stage 13 light-gray background and 2× plate title.

Build targets and profile selectors

make generate-network-groundstations
make generate-network-groundstations-artifacts
make generate-network-groundstations-cahill-keyes

network-groundstations, groundstations, and starlink are generation-profile aliases. Because the pass is standard, its six SVG, PDF, PNG, and Cahill–Keyes snapshot products are part of the ordinary make all graph.

Published v14 previews

Network Groundstations is a new v14 pass and is present in all six whole-map projections of the immutable v14 AAO release:

Each product also has a 480-pixel thumbnail, a print PDF, a master .svg.gz, and 1920 × 1080 PNG/WebP derivatives under the same projection directory.

Verification

make check-network-groundstations verifies every checked static payload against SHA256SUMS. The generator reopens every SVG and checks its viewBox, required semantic groups, exact groundstation element counts, provenance metadata, font, and finite coordinates.
