Learning from drone data with GeoNadir

the problem with data directly from drones

Drones can be a valuable addition to any STEM classroom as a fun, interesting and tactile way for students to engage in problem-solving. But having drones in the classroom isn’t just about the skills students can learn by flying them. It’s also about teaching students how to analyse and apply problem-solving skills to the data drones collect.

The problem with drone data

When drones fly mapping missions, they’re just taking lots of individual photos tagged with location metadata. These photos are what you’ll see when you go to download data from the drone.

While all of the interesting or important information that you mapped is there in the photos, they’re not very user-friendly to work with or learn from. Plus, in this raw format, these images can take up a lot of storage space, and be difficult to easily share between students.

So how can we get this data in a format where students can focus on high-level problem solving rather than just trying to get the data into a manageable format? One option is to upload drone data from your class mapping missions to GeoNadir.

What is GeoNadir?

GeoNadir is a free online platform for sharing and storing drone mapping data. Using it is as simple as creating an account and uploading a dataset. There are lots of benefits to uploading your data to GeoNadir.

Free storage

GeoNadir offers free and secure storage for your drone mapping data, so you don’t have to worry about it cluttering up your or your student’s hard drives. Anyone can access it anywhere, anytime online.

Automatic orthomosaic generation

When you upload a dataset, the platform automatically generates an orthomosaic from the raw photos – one continuous image of the mapped area corrected for any distortions. Professionals commonly use orthomosaics, and students can learn from them more easily than raw images.

Easy sharing

Any dataset uploaded to GeoNadir is available and visible to anyone who visits the website. So sharing an orthomosaic is as simple as sharing a link.

In-built basic analysis with the create feature

Not only is sharing orthomosaics super-straight forward, the platform also has an in-built “create” feature. You can use it for labelling, measuring and highlighting different features of the orthomosaic, so students can start learning from the data straight away!

More options for in-depth dataset analysis are on the way

On top of all of the features currently available on the platform, there are also a range of new and exciting features currently in development that are prioritised for delivery in the next six months. These include:

  • A unique web mapping service link for each dataset so you can analyse your data in other programs like ArcGIS online
  • The ability to view your dataset in three dimensions with digital surface and terrain models
  • Downloadable orthomosaics, surface models and terrain models
  • The ability to make datasets private

How do I use GeoNadir to manage my drone data?

You can start using GeoNadir in 3 easy steps:

1.  Create a profile

You can create a profile from the GeoNadir website or directly on the platform by clicking on the account icon in the top right corner of the screen. You can also link your account to your google account, or opt to have a passwordless login that just requires your email address.

2.  Upload a dataset

Once you’ve logged in, click the upload button and follow the prompts to upload your dataset to the platform.

Make sure you include useful information in the title and tags of your dataset. Not only will this help you and your students remember the details of the mapping mission, it also makes it easier for other people to use and learn from your mapping mission.

Not sure what information to include with your dataset? Check out this article for some ideas.

You can find the datasets you’ve uploaded by clicking on your account icon, or through the search function.

1.  Start creating

With the create function, you can measure and annotate datasets to highlight important features or collect quantitative information from your drone data. Get started by searching for a dataset you’re interested in. Once you’ve toggled the orthomosaic so it’s visible on the map, click the “create” button.

From there you can add and edit whatever features you’d like to the orthomosaic. You can read in more detail how to use the create function here.

Currently, you can not save or export layers from the create function, so you’ll need to screenshot anything you create so you don’t lose it. The ability to save layers to a project folder is coming soon though, so be on the lookout!

Access drone data from around the world

GeoNadir isn’t just a useful platform for the storage and analysis of drone data that your class has collected. Researchers and other professionals upload datasets to GeoNadir from all over the world.

Students can use these datasets to learn about how drones are being applied to solve real-world problems. You can read the stories behind some of these datasets on the Stories from Above blog on the GeoNadir website.

Getting started with drone mapping

We have a teacher professional learning course that will take you through how to use sub 2kg drones to conduct a drone mapping mission.

This course is available inside the She Maps Membership. Click here to get started.
