DELTA combines satellite imagery, orthophotos and 3D models to help military personnel track terrain changes and plan operations more precisely.

This was reported by the Ministry of Defense of Ukraine.

The system uses data from several satellite providers, which is regularly updated. In July 2026 alone, military personnel uploaded more than 1,700 orthophotos to DELTA.

An orthophoto is an accurate digital photographic image of terrain that has been aligned to a unified coordinate system and scale.

What data does DELTA use?

Satellite imagery provides broad coverage — from the entire territory of Ukraine, including temporarily occupied territories, to the territory of russia.

This allows military personnel to monitor changes across large areas, identify new objects and prepare operations at significant distances.

Orthophotos, meanwhile, are obtained using reconnaissance drones. They are used for detailed examination of specific areas where satellite data is insufficient.

The high level of detail in these images makes it possible to detect small changes in the terrain and objects that may remain unnoticed in satellite imagery.

Combining different types of geospatial data allows military personnel to assess terrain in advance, identify potential targets, analyze the effects of strikes and plan movement routes.

Another DELTA feature is automatic notification when new imagery of designated areas becomes available.

This allows military personnel to quickly respond to changes within their area of interest and use updated information for further planning.

3D models help plan routes

Another source of information in the system is three-dimensional terrain models. They show not only objects, but also terrain features and their elevation.

Such data is already being used, in particular, to plan routes for ground robotic systems.

For these systems, elevation changes, slopes and other terrain characteristics can be crucial when selecting a route.

The more data, the more useful the system

Up-to-date orthophotos and 3D models added to DELTA by individual units become available across the entire ecosystem.

This allows adjacent units to use information about the same area and take the latest changes into account in their own planning.

DELTA users can also learn how to create and upload orthophotos themselves — detailed instructions are available for this purpose.

The Ministry of Defense’s next task is to scale up this area and further increase the amount of up-to-date geospatial data that military personnel can directly use in DELTA.

As ArmyInform reported, the AI assistant in DELTA has become available to everyone: it already handles a quarter of requests, has reduced the time from contacting support to receiving assistance by 27%, and has made responses 30 times faster.
