East View Geospatial (EVG), a provider of cartographic products, is building a library of geospatial training data for use in supervised machine learning applications. EVG is offering, at no charge, a sample foundation geospatial training dataset developed during an R&D pilot in Papua New Guinea.
“Machine learning algorithms applied to geospatial projects, such as automated feature identification in remotely sensed imagery, are only as accurate as their training data,” says Rod Buhrsmith, EVG business development. “Our goal is to push the accuracy of supervised geospatial machine learning applications to 95 percent or higher.”
EVG is building the training data library with platform developers and end users in mind. Developers of supervised machine learning platforms will use the datasets to enhance and calibrate the performance of their algorithms. Geospatial professionals will rely on the training data to improve the results of machine learning applications in real-world projects.
In the geospatial arena, machine learning focuses on the application of big data analytics to automate the extraction of specific information from massive geospatial datasets. The most common are imagery or video streams captured by aircraft, drone or satellite, which traditionally are analyzed manually to identify features, land use/land cover and changing conditions on the ground.
Supervised machine learning requires ingestion of a sample data set covering a small geographic area to train the algorithms to identify specific features or ground conditions, such as road networks or healthy wheat fields. The machine learning platform then scales up its big data analytics capabilities to search much larger regional or even global databases of imagery to find other instances of those features.
“The benefit of geospatial machine learning is that every pixel is analyzed and the information is extracted faster than would be possible with manual methods,” says Mark Knapp, EVG product development.
EVG initiated the Papua New Guinea R&D pilot to develop a state-of-the-art process for creating authoritative and accurate training data sets specifically tailored to supervised machine learning usage by leveraging its in-house expertise and geospatial data archive. Samples of the Papua New Guinea data sets — covering transportation, hydrology, infrastructure and land use/land cover — are available now.

Going forward, EVG will create custom training data sets for specific supervised machine learning applications and geographic areas in parallel with development of off-the-shelf data for on-demand purchase. The geospatial data will be drawn from the EVG archive, which includes imagery, maps and charts, as well as topographic, 3D, DEM, GIS and vector data sets. Much of the data is locally sourced in parts of the world not accessed by any other commercial cartographic organization. Areas include Russia, China, Iran, former Soviet Union, Middle East, East Asia and North Africa.
“We have the ability to create authoritative training data sets for any part of the world, meeting the accuracy requirements of both commercial GIS and military GEOINT applications,” Knapp says.
