Tips on Collecting Data

Pilots collect data with the flight app, typically using an automated grid flight pattern with at least 60% overlap. Higher overlap settings help ensure data product quality, while also increasing flight times and the number of images captured. Detailed flight paths can be created directly within the Measure Ground Control (MGC) flight app or in the web portal.

Uploading Data

After data collection, images are uploaded to the mission page in the MGC web portal. When selecting to send images for processing, you will have the opportunity to review each image, along with its capture location, to confirm data quality prior to processing. Deselect and images you don't want to include, confirm the number of images to be processed, and submit.

Data Processing by Pix4D

Images are processed and data products are created through a seamless integration with Pix4D, the industry leader in photogrammetry. Processing time varies anywhere from an hour for small maps to more than 24 hours for very large maps in excess of 1500 images. You will receive a notification when processing is complete, and you’ll have the following data products to view or download:

  • Orthomosaic
  • Digital Surface Model (DSM)
  • Contour Map

Viewing and Using Your Data Products

Ground Control’s built-in map viewer is an advanced platform for viewing your data products in 2D. You can turn layers on and off, import your own 2D layer, and add information like the flight path. Because we use one, continuous base map, you can also move easily among all of your projects by zooming in and out and moving around the map.

You can use the tools on the right of the screen to measure distance and area. You can also export your data products and other data layers for use in common GIS software platforms. Orthos and DSMs can be exported as GeoTIFF files while contours and flight paths can be exported as GeoJSON files.

Fly with Third Party Software

While we always recommend you plan on fly on Measure's web and mobile apps, we know sometimes this isn't possible. If you're flying with hardware we do not support, or prefer to use apps like DJI Pilot, you can still upload the data for processing to Measure Ground Control. Regardless of the flight hardware and software you're using, make sure your drone is taking JPEGS and you have sufficient frontal and side overlap
