ArcGIS for On‑Board Data Collection

A) On‑Truck Apps & SDKs

Need	ArcGIS piece	Notes	Refs
Show maps offline; draw/collect features; geofence	ArcGIS Maps SDKs (Runtime)	Native SDKs for Android/iOS/.NET/Qt. Support offline data, editing, and Geotriggers on-device.	Maps SDKs (Native) • Geotriggers
Turn‑by‑turn even when disconnected	ArcGIS Navigator	Offline navigation using packaged maps & network datasets; integrates with field apps.	Navigator documentation
Device‑side routing & map display	Runtime routing	Runtime samples show offline routing and map matching.	Routing & navigation

B) Offline Maps & Geofences

Mobile Map Package (MMPK) for basemaps + layers + locator + network dataset created in ArcGIS Pro, then sideloaded or downloaded to devices.
Mobile geodatabases (SQLite) for editable feature layers; sync when connectivity returns.
Geotriggers (Maps SDK) to notify when entering/exiting polygons (school zones, noise windows, weight limits) without the cloud.

C) Field Data Capture (ready‑made apps)

App	Best for	Offline	Refs
ArcGIS Field Maps	Map‑centric editing, inspections, attachments	Yes (sync later)	Field Maps docs
Survey123	Smart forms with logic, photos, barcodes	Yes	Survey123 docs
QuickCapture	Big‑button tap‑to‑record incidents at speed	Yes	QuickCapture docs

D) Real‑Time Streaming (MQTT/HTTP)

ArcGIS Velocity (ArcGIS Online) can subscribe to MQTT/HTTP streams, run real‑time analytics & geofences, and write to feature layers. For on‑prem, ArcGIS GeoEvent Server performs similar ingestion/geofencing in ArcGIS Enterprise.

Refs: ArcGIS Velocity • What is ArcGIS GeoEvent Server?

E) Ops Dashboards & Feature Services

ArcGIS Dashboards visualizes live truck locations, stops, and alerts from feature/stream layers.
Persist edits via the ArcGIS REST applyEdits API; supports batch updates and attachments.

Refs: ArcGIS Dashboards • ArcGIS REST — Feature Service: applyEdits

F) Example Flows & JSON

1) Disconnected Shift (offline edits → sync)

Load MMPK + mobile geodatabase on device.
Collect features/attachments with Field Maps or a Runtime app.
When back online, sync or POST applyEdits to the feature service.

2) Live Exception (edge → Velocity → Dashboard)

On‑truck service posts an MQTT message:

{
  "truck_id": "TRUCK-12",
  "event": "blocked_alley",
  "stop_id": "STOP-7781",
  "lat": 37.7812,
  "lon": -122.4058,
  "photo": "file://blocked_102_pine.jpg",
  "time_utc": "2025-10-05T14:02:00Z"
}

ArcGIS Velocity ingests, checks geofences, writes a record to a feature layer.
ArcGIS Dashboards displays the alert with filter/actions.

3) applyEdits request (illustrative)

POST /FeatureServer/0/applyEdits
Content-Type: application/json

{
  "adds": [{
    "attributes": {
      "truck_id": "TRUCK-12",
      "event": "blocked_alley",
      "stop_id": "STOP-7781",
      "note": "Dumpster across alley",
      "timestamp": 1730748120
    },
    "geometry": { "x": -122.4058, "y": 37.7812, "spatialReference": {"wkid": 4326} }
  }]
}

G) Security & Governance

Least privilege: use item‑based access and token/cert auth; avoid admin tokens on devices.
Offline integrity: sign data packages; verify before load; sandbox file imports.
Privacy: minimize PII; redact/blur faces/plates on‑device if capturing video/photos.
Quality: collocate sensors for calibration; log versions of models/prompts used for analytics.
