Let us manage your data labeling project
Through our partnership with CloudFactory, we’ve supervised data labeling services for a wide range of clients, including earth observation specialists, Fortune 500 enterprises, and international development organizations. Whether it’s semantic segmentation, change detection, or classification, our team can get it done for you.
SERVICES
Managing the annotation process for you
Our labeling lead removes the hassle of annotation management by designing training materials, communicating with labelers, tracking progress, and providing quality assurance. Services include:
- Regularly validating labeling output and providing targeted feedback as often as needed.
- Triaging labeler questions: answering routine queries, while understanding when to bring issues to your attention.
- Escalating technical issues to our product engineers for immediate attention.
- Providing regular updates on campaign status and expected completion dates.
- Prioritizing projects or tasks based on your timeline.
- Developing custom workflows.
- Re-evaluating campaign design and recommending changes as needed.
PROCESS
Designed specifically for your needs
Optimizing your machine learning project for annotation starts before data labeling begins, and we’re here to walk you through it.
Read some of our takeaways from training a data labeling team or tips for optimizing your labeling project on our company blog.
Our team helps you design the right type of annotation campaign, image processing, and tools for your use-case. Most importantly, our labeling lead works directly with you and the team at CloudFactory to make sure the project stays on track and that the labels are of the highest quality. Throughout the process, you’ll have GroundWork Pro access, which gives you more room to grow your projects.
VALIDATION
Validated labels boost the performance of your machine learning model
Our labeling workflow ends with the validation of your data. Each labeled task is looked at again and evaluated for accuracy.
It is then either accepted, modified, or rejected and sent back to the queue for relabeling. Validators are able to leave notes documenting any issues and giving instructions on needed adjustments. In our experience, validated labels can provide a significant boost to a machine learning model’s performance.

LABELERS
Partnering for quality
At the heart of our managed annotation work are CloudFactory data analysts. CloudFactory invests in the professional and personal development of its workforce, and it pays dividends in the quality of their work.
With a team dedicated to GroundWork clients, we can get started on your campaign within days as opposed to weeks without a long-term commitment.

Our data analysts are seasoned GroundWork users with in-depth knowledge of its features, maximizing the efficiency of your labeling time. Many have worked with the tool from its inception and have played an integral role in suggesting and developing features that increase productivity and annotation quality. We communicate and problem-solve with them daily.
CASE STUDIES
We’ve partnered with a variety of organizations to support their machine learning projects
International Development Organization
We worked with one of the largest international development organizations to create a dataset of urban tree canopy cover in Freetown, Sierra Leone.
In addition to our labeling services, we provided training, tracking, and feedback for their teams of managers and student labelers in Sierra Leone and Tanzania. The labeled data was used to train a feature detection algorithm.

Cloud Detection Model and Labeling Competition
Cloud cover is one of the most pernicious problems of satellite imagery. One of our machine learning engineers decided to tackle this problem by building a cloud detection model. Our professional annotators produced over 20,000 labels for the model and learned to identify and annotate several different types of cloud cover. We also ran a cloud labeling competition for amateur labelers as part of a partnership with Radiant Earth. Within a week, participants from across the world had mapped around 2.3 million square kilometers of satellite imagery to create a signature training dataset and raise awareness of the SpatioTemporal Asset Catalog (STAC) spec.

Tell us your labeling needs




With our customers, we’ve produced hundreds of thousands of labels on low- and high-resolution optical imagery as well as SAR imagery. Those labels include artificial and natural features, such as: cooling towers, solar panels, vehicles, storage tanks, and forests, bodies of water, clouds, and land cover.Learn more about our services.
Have labels that need to be cleaned up? Need help creating your machine learning models? We can do that, too!
