Check and process BGT updates more quickly

The built environment is constantly changing: new buildings are added, waterways are altered, and green spaces or land areas change. Identifying these changes is often outsourced, but the responsibility for verification remains with you. And keeping track of those changes to maintain an up-to-date Large-Scale Topography Database (BGT) is a challenge and takes a lot of time. Often, this is done manually or is spread across different systems. As a result, changes are regularly left unprocessed. IMAGEM streamlined this process by digitizing the verification of detections. This creates a clear overview, allows you to work more efficiently, and enables you to process changes in the BGT more quickly.

To speed up the verification and processing of BGT changes, IMAGEM has digitized IMAGEM process of reviewing and resolving detected changes. All detected changes are displayed centrally in a single workspace. This provides an immediate overview: employees can see where a potential change has been detected, what information is available, and what action is required.

Important contextual information, such as permits, case management systems, or panoramic images, can be added automatically. As a result, an administrator no longer needs to search for information across multiple systems but can assess a situation directly within its broader context.

Faster assessment with visual context

In the digital work environment, changes are clearly displayed on the map. Administrators can immediately inspect the area visually using additional resources, such as panoramic or oblique images. This provides a quick overview of what has changed on-site, without the need for an immediate field visit.

Based on this visual inspection, the situation can be easily assessed. With a single action, it is determined whether:

  • The change must be implemented in the BGT
  • additional verification is required
  • the detection turns out not to be a mutation

Once the assessment is recorded, the next task is automatically displayed, creating an efficient and continuous to-do list.

The benefits of the digital workflow

Always stay updated on progress

A key advantage of the digital workflow is the clear overview it provides. Dashboards make it immediately clear:

  • how many detections are still pending
  • which have already been reviewed
  • and where extra attention is needed where possible

The system also records who reviewed each change and the outcome of that review. This ensures that the process remains transparent and verifiable. In addition, results can be automatically compiled into a structured file. This makes it easy to take the next steps, such as forwarding the data to registration management or other processes.

Assistance in reviewing changes

Because many detections contain recurring patterns, technology can help in assessing them. An AI agent analyzes detections and automatically assigns an initial indication of the type of mutation, known as a " prestatus." This provides employees with immediate guidance for their assessment.

This support helps identify more quickly where attention is needed and which alerts can be resolved immediately. Furthermore, the range of alert types that AI can recognize and assess is constantly expanding. As a result, the process of reviewing changes is becoming more efficient step by step.

Result: a streamlined change management process

By combining change detection with a streamlined digital review process, maintaining the BGT becomes more organized and manageable. Detections no longer go unaddressed, employees work more efficiently, and the quality of the records remains high. And perhaps most importantly: verifying changes becomes a straightforward process rather than a time-consuming search.
