# Module: Common/DTO
|
||
|
||
## Purpose
|
||
Data transfer objects used across all layers — API requests/responses, inter-service communication, and queue messages.
|
||
|
||
## Public Interface
|
||
|
||
### GeoPoint
|
||
Geographic coordinate with tolerance-based equality.
|
||
- `Lat` (double): latitude, JSON property `"lat"`
|
||
- `Lon` (double): longitude, JSON property `"lon"`
|
||
- Constructor: `GeoPoint()`, `GeoPoint(double lat, double lon)`
|
||
- Equality: two points are equal if both coordinates differ by less than `0.00005` (PRECISION_TOLERANCE)
|
||
- Operator overloads: `==`, `!=`
|
||
|
||
### Direction
|
||
Result of a directional calculation between two points.
|
||
- `Distance` (double): distance in meters
|
||
- `Azimuth` (double): bearing in degrees (0–360)
|
||
|
||
### SatTile
|
||
Represents a single map tile with its spatial bounds.
|
||
- `X`, `Y` (int): tile coordinates in the slippy map scheme
|
||
- `Zoom` (int): zoom level
|
||
- `LeftTop`, `BottomRight` (GeoPoint): computed bounding box corners (via `GeoUtils.TileToWorldPos`)
|
||
- `Url` (string): download URL
|
||
- `FileName → string`: formatted as `{X}.{Y}.{Zoom}.jpg`
|
||
|
||
### TileMetadata
|
||
Metadata about a stored tile (mirrors `TileEntity` but without DB-specific concerns).
|
||
- `Id` (Guid), `TileZoom`, `TileX`, `TileY` (int), `Latitude`, `Longitude` (double)
|
||
- `TileSizeMeters` (double), `TileSizePixels` (int), `ImageType` (string)
|
||
- `MapsVersion` (string?), `Version` (int), `FilePath` (string)
|
||
- `CreatedAt`, `UpdatedAt` (DateTime)
|
||
|
||
### RegionRequest
|
||
Queue message for async region processing.
|
||
- `Id` (Guid), `Latitude`, `Longitude` (double), `SizeMeters` (double)
|
||
- `ZoomLevel` (int), `StitchTiles` (bool)
|
||
|
||
### RegionStatus
|
||
Response DTO for region status queries.
|
||
- `Id` (Guid), `Status` (string), `CsvFilePath`, `SummaryFilePath` (string?)
|
||
- `TilesDownloaded`, `TilesReused` (int), `CreatedAt`, `UpdatedAt` (DateTime)
|
||
|
||
### RoutePoint
|
||
Input point in a route creation request.
|
||
- `Latitude` (double, JSON: `"lat"`), `Longitude` (double, JSON: `"lon"`)
|
||
|
||
### RoutePointDto
|
||
Output point in a route response (includes computed fields).
|
||
- `Latitude`, `Longitude` (double), `PointType` (string: "start"/"end"/"action"/"intermediate")
|
||
- `SequenceNumber`, `SegmentIndex` (int), `DistanceFromPrevious` (double?)
|
||
|
||
### CreateRouteRequest
|
||
API request body for route creation.
|
||
- `Id` (Guid), `Name` (string), `Description` (string?)
|
||
- `RegionSizeMeters` (double), `ZoomLevel` (int)
|
||
- `Points` (List\<RoutePoint\>), `Geofences` (Geofences?)
|
||
- `RequestMaps` (bool), `CreateTilesZip` (bool)
|
||
|
||
### RouteResponse
|
||
API response for route queries.
|
||
- All fields from the route entity plus `Points` (List\<RoutePointDto\>)
|
||
- `MapsReady` (bool), `TilesZipPath` (string?)
|
||
|
||
### GeofencePolygon
|
||
Axis-aligned bounding box defined by NW and SE corners.
|
||
- `NorthWest` (GeoPoint?), `SouthEast` (GeoPoint?)
|
||
|
||
### Geofences
|
||
Container for multiple geofence polygons.
|
||
- `Polygons` (List\<GeofencePolygon\>)
|
||
|
||
## Internal Logic
|
||
- `GeoPoint` uses a precision tolerance of `0.00005` degrees (~5.5 meters) for equality comparison.
|
||
- `SatTile` eagerly computes its bounding box corners on construction by calling `GeoUtils.TileToWorldPos`.
|
||
|
||
## Dependencies
|
||
- `GeoPoint`, `Direction` — no imports
|
||
- `SatTile` → `SatelliteProvider.Common.Utils.GeoUtils`
|
||
- All others — no internal dependencies (or only `System.Text.Json.Serialization`)
|
||
|
||
## Consumers
|
||
- All services, repositories, and API endpoints consume these DTOs
|
||
- `RegionRequest` is the message type for `IRegionRequestQueue`
|
||
|
||
## Data Models
|
||
These ARE the data models (DTOs). They map closely to the database entities but are decoupled from the persistence layer.
|
||
|
||
## Configuration
|
||
None consumed directly.
|
||
|
||
## External Integrations
|
||
None.
|
||
|
||
## Security
|
||
None.
|
||
|
||
## Tests
|
||
No dedicated DTO tests.
