Datenmodelle

Die wichtigsten Objektformen, die die API zurückgibt. Zeitstempel sind Epoch-Millisekunden, sofern nicht anders vermerkt.

Marker

interface Marker {
  id: string;
  latitude: number;
  longitude: number;
  title: string;
  description?: string;      // Markdown
  color: string;            // hex, e.g. "#3B82F6"
  markerIconId?: string;    // reference into the room icon registry
  markerIconSize?: number;  // per-marker size override (px)
  tags?: string[];
  createdBy: string;
  createdAt: number;
  eventDate?: number;       // for the timeline
  imageKey?: string;        // storage key — fetch via .../markers/image?key=…
  thumbnailKey?: string;
  imageBlob?: string;       // legacy inline image, superseded by imageKey
  thumbnailBlob?: string;   // legacy
  embeddedMediaUrl?: string; // YouTube / Vimeo / external
  mediaSize?: 'sm' | 'md' | 'lg'; // embedded-media popup width (default 'md')
  imageMetadata?: ImageMetadata;  // EXIF read from the attached photo — read-only
}

interface ImageMetadata {
  gpsSource: boolean;      // true when the marker sits where the photo was taken
  cameraMake?: string;
  cameraModel?: string;
  dateTaken?: number;      // epoch ms
  altitude?: number;
  orientation?: number;
}

imageMetadata entsteht, wenn in der App ein Foto angehängt wird — ein geotaggtes Foto verschiebt den Marker an seine GPS-Position und setzt gpsSource. Über die API ist das Feld nicht setzbar, und ein Austausch von imageKey/thumbnailKey löscht es, damit ein neues Foto nie die Herkunft des vorherigen erbt.

Die Endpunkte für einzelne Marker (GET/PATCH /api/rooms/:roomId/markers/:markerId) lassen createdByEmail und die Inline-Blob-Felder (imageBlob, thumbnailBlob, iconBlob) in ihren Antworten weg; der Listen-Endpunkt liefert die gespeicherte Form unverändert.

PolygonLayer

interface PolygonLayer {
  id: string;
  name: string;
  description?: string;
  geometryType?: string;    // "Polygon" | "MultiPolygon" | "LineString" | ...
  color: string;
  opacity: number;          // 0–1
  strokeWeight: number;     // px
  visible: boolean;
  totalFeatureCount?: number;
  createdBy: string;
  createdAt: number;
  eventDate?: number;
  bbox?: [number, number, number, number]; // [minLon, minLat, maxLon, maxLat]
}

RasterLayer

interface RasterLayer {
  id: string;
  name: string;
  description?: string;
  fileSize: number;         // original TIFF size, bytes
  bounds: [number, number, number, number];
  minZoom: number;
  maxZoom: number;
  opacity: number;          // 0–1
  visible: boolean;
  createdAt: number;
  eventDate?: number;
  processingStatus?: 'pending' | 'processing' | 'complete' | 'error';
  // display (see the Raster Layers reference)
  colormap?: string;
  vmin?: number;
  vmax?: number;
  band?: number;            // 0 = natural color / all bands
  renderMode?: 'tiles' | 'image_overlay' | 'rgb';
  rgbBands?: [number, number, number]; // 1-based [R, G, B]
}

MarkerIcon

interface MarkerIcon {
  id: string;
  name: string;
  iconBlob: string;   // image data (base64)
  category?: string;
  size: number;       // display height in px (default 27)
  createdAt: number;
}

Room & RoomMember

interface Room {
  roomId: string;
  createdBy: string;    // owner's user ID
  createdAt: number;
  markerCount: number;
  commitCount: number;
  lastActivity?: number;
  isPublic?: boolean;
}

interface RoomMember {
  userId: string;
  email: string;
  name?: string;
  role: 'owner' | 'editor' | 'viewer';
  addedBy: string;
  addedAt: number;
}
