In this article, we’ll explore:

  • What is OpenDroneMap
  • The ODM family (WebODM, NodeODM, CloudODM, etc.)
  • How to use ODM for processing drone images
  • How to customize ODM for your own business requirements
  • Offline vs cloud-based deployment options
  • Why Manya Technologies is your ideal partner for custom web-based drone mapping
  • Conclusion

What Is OpenDroneMap?

OpenDroneMap (ODM) is an open-source photogrammetry toolkit that transforms aerial images into:

  • Orthomosaic maps
  • Digital Surface Models (DSM)
  • Digital Terrain Models (DTM)
  • Dense point clouds
  • 3D textured models
  • Camera position & quality reports

It is widely used because it’s:

  • Completely open-source
  • Cost-effective
  • Reliable
  • Regularly updated
  • Developer-friendly

ODM follows a multi-step pipeline to convert images into useful GIS outputs:

  1. Image Preprocessing
  2. Feature Extraction
  3. Structure from Motion (SfM)
  4. Multi-View Stereo (MVS)
  5. Dense Point Cloud Generation
  6. DSM, DTM & Orthomosaic Creation

ODM Family: Components You Need to Know

ODM is not just one tool—it’s an ecosystem. Here’s the ODM family:

1. ODM (Core Engine)

Command-line engine that does the heavy processing (SfM, DSM, Point Cloud, Ortho).

2. NodeODM

A lightweight processing server that exposes ODM via API.
Useful for automation, integrations, and scaling.

3. WebODM

A user-friendly web dashboard built on top of NodeODM.
Features:

  • Upload images
  • Set processing options
  • View 2D/3D outputs
  • Generate reports
  • Manage projects

4. CloudODM

Used to send jobs to remote servers or cloud machines.

5. PyODM

Python bindings to control ODM programmatically.

6. ClusterODM

Distributed processing for very large datasets (50,000–100,000+ images).


How to Use OpenDroneMap (Step-by-Step)

Step 1: Collect Drone Images

Ensure:

  • 70–80% overlap
  • 60–70% sidelap
  • Proper lighting
  • Consistent altitude
  • Correct camera angles

Step 2: Use WebODM / NodeODM / CLI

Most beginners use WebODM, which provides a clean interface.

Upload → Select Options → Process → Download Outputs

Step 3: Analyze Processed Results

ODM generates:

  • Orthomosaic (GeoTIFF)
  • DSM, DTM
  • Point cloud (LAS/LAZ)
  • Mesh (OBJ)
  • Camera positions
  • Quality report

Step 4: Export to GIS Tools

Outputs work with:

  • QGIS
  • ArcGIS
  • CesiumJS
  • Leaflet
  • Potree
  • Custom map viewers

How to Customize ODM for Your Requirements

This is where many companies need specialized development. ODM is powerful, but businesses often need:

✔ Custom Processing Options

  • Auto-GCP detection
  • Accuracy-based processing presets
  • Real-time stitching
  • Custom photo quality filters
  • Auto-detection of blurry or inconsistent images

✔ Custom Web Dashboard

Branding + customized workflows:

  • Project management
  • User roles
  • Automated billing
  • API integrations
  • Client sharing portal

✔ Integration With Existing Platforms

  • UAV flight logs
  • Drone telemetry
  • ERP or govt systems
  • GeoServer / MapServer
  • Cesium 3D Tiles processing

✔ Post-Processing Automation

  • Auto orthomosaic clipping
  • Auto contour generation
  • Change detection
  • Vegetation/NDVI analysis
  • Volume estimation for mining

✔ High-volume Data Support

For 10,000–100,000 images:

  • ClusterODM setup
  • GPU acceleration
  • Distributed workflow
  • Parallel task execution

If your business requires any of the above, it’s best handled by an experienced GIS & drone-mapping software development team.


Offline vs Cloud Options

Manya Technologies helps you deploy ODM according to your infrastructure:

✔ Offline / On-Premise

Perfect for government, defense, and confidential commercial work.
