Object Detection

Detect common objects in satellite imagery

Quick Start

import { geoai } from "@geobase-js/geoai";
 
// Initialize pipeline
const pipeline = await geoai.pipeline(
  [{ task: "object-detection" }],
  providerParams
);
 
// Run detection
const result = await pipeline.inference({
  inputs: { polygon: myPolygon },
});
 
console.log(`Found ${result.detections.features.length} objects`);

🎯

Detects 12+ object classes including vehicles, buildings, boats, and infrastructure in aerial imagery

Parameters

Post-Processing

postProcessingParams: {
  confidence: 0.8; // confidence range (0.0-1.0)
}

Map Source

mapSourceParams: {
  zoomLevel: 18; // Image resolution (16-20)
}

See Map Source Parameters for more details.

Detected Objects

Object	Use Cases
`LightVehicle`	Traffic analysis, parking assessment
`Person`	Crowd monitoring, activity analysis
`Building`	Urban planning, damage assessment
`Truck`	Commercial traffic analysis
`Boat`	Marine traffic, port activity
`SolarPanels`	Renewable energy assessment
`Container`	Logistics, port operations
`Bus`	Public transit analysis

Output

Returns GeoJSON with detected objects and their confidence scores:

{
  detections: {
    type: "FeatureCollection",
    features: [
      {
        geometry: { /* polygon coordinates */ },
        properties: {
          class: "LightVehicle",
          confidence: 0.92
        }
      }
    ]
  }
