GROUND CONTROLWhat, Why and How

• Ground control points are features with known coordinates that can be identified

in your raw images.

- Coordinates must be entered into the software.

• Without ground control, GPS alone enables outputs that are in approximately the

proper location & scale, but accuracy will be unspecified (x, y, and z).

• Control points are necessary to ‘anchor’ your project. With adequate control, the

natural rigidity of the geometry provides good accuracy between control points.

• Best practices:

- Multiple points, distributed around project.

- Survey all control in the field (if possible), with high contrast markers (Size > 10 pixels).

- Some points withheld from processing as checkpoints to measure accuracy.

Best Practices for Drone2Map

1. Ensure your flight plan captures good quality data

- Overlap ~70% or more, proper focus & exposure

Best Practices for Drone2Map

1. Ensure your flight plan captures good quality data

- Overlap ~70% or more, proper focus & exposure

2. Run initial processing without creating any outputs, then review processing

report before proceeding

3. Ground control should be considered mandatory

4. If project includes oblique imagery, use a clip polygon

5. Scaling up to large projects

- Duplicate images with GCPs in overlap (Future release will allow project merge)

6. Data management

- All flight metadata in geodatabase

- Outputs and possibly raw images managed using mosaic datasets
