At WWDC 2019, Apple announced Maps Web Snapshots for creating a static map from a URL.

• Documentation at developer.apple.com/documentation/snapshots
• Maps Snapshot Studio from Apple — maps.developer.apple.com/snapshot
• Web service endpoint and notes on the query parameters — developer.apple.com/documentation/snapshots/create_a_maps_web_snapshot
• Developer Forum with the tag: Maps Web Snapshots
  • Forum thread on Image annotations larger than 50px
• Announcement from the Apple Developer Forums (around WWDC 2020):
  • Now Available: Image Annotations on Maps Web Snapshots

Usage

Update your credentials in config.json then install and run.

# config.json
#   Do not commit your secrets
{
  "teamId":             "XXXXXXXXXX",
  "keyId":              "YYYYYYYYYY"
  "privateKey": "AuthKey_YYYYYYYYYY.p8",
}

# install
npm install

# run and inspect output
mapkit-snapshots.js null-island.geojson -c config.json

Online help

Online help is available by supplying no parameters.

mapkit-snapshots.js

Usage:
  mapkit-snapshots.js <file.geojson> -c config.json     # -c pass in privateKey, teamId, keyId
  mapkit-snapshots.js <file.geojson> -c config.json -o  # -o opens in default browser

Apple MapKit JS Examples

This repo shows working samples of Maps Web Snapshots and Node JS sample code for generating the proper URLs to use in your applications.
