Monitor the Pace of Construction With AI

  • Client Profile

    Industry: Construction
    Location: Finland
    Size: 1-10 employees

  • Company Bio

    The client is a visual dropbox for modern mapping via drones, landscanners and many other tools. Their solutions allow you to share, use and manage any modern geospatial 3D documentation in a web browser - and access it throughout the whole project or an asset’s life cycle.


The client developed a product that monitors the progress of construction over time. To improve the accuracy of the product, they needed to annotate images of construction sites from various years.


In order to increase the accuracy of their product, the client needed their datasets to be annotated to train the machine learning algorithms. Such datasets would include images of how construction sites look today and how they looked a couple of years ago. Both of these datasets needed to be annotated so the system could compare them and measure the progress that was made, if any. Since there was a large amount of data that needed to be annotated, the client approached Mindy Support for assistance.

Solutions Provided by Mindy Support

We assembled a team of 10 full-time data annotators to label the needed datasets. The client requested that we use QGIS to perform the annotation, which is a free and open-source tool specifically designed for annotating geospatial data. The output needed to be in GeoJSON format which is used for encoding a variety of geographic data structures.

We needed to label things like construction, parking, paths, roads, stadiums and paved and unpaved surfaces on the images. In total, we worked around 1,000 total hours to get the needed amount of data annotated within the specified time-frame.

Mindy Support is ISO 9001 and ISO 27001 certified. Our information security management system (ISMS) is built on the basis of international standards that helps organizations keep information assets secure.

We are committed to respecting all rights of the data subjects under the General Data Protection Regulation (GDPR) (EU) 2016/679. According to the Article 28 of the GDPR, the relationship between the controller and the processor are regulated by Data Processing Agreement, which we put in place with every Client.
