In this piece, amanda lind from Blue marble Geographics introduces an innovative feature in Global Mapper Pro v25.1 that automates the identification and marking of ground control points (GCPs) in aerial imagery.
Ground control points play a crucial role in enhancing the accuracy of photogrammetric processes. The latest version of Global Mapper Pro has considerably advanced this capability.
Incorporating GCPs into image processing allows users to utilize the precision of high-accuracy GNSS devices wiht drone-captured imagery. historically, this has been a labor-intensive task, requiring each point feature to be meticulously linked to its corresponding pixel across the entire image dataset. The new tool in global Mapper Pro v25.1 simplifies this by automatically identifying and marking GCPs, thereby expediting the workflow.

The Pixels to Points (P2P) feature within Global Mapper Pro is a photogrammetric processing tool that generates photo-textured 3D models, orthoimages, and high-resolution point clouds from overlapping images. These data models can be utilized in Global Mapper for various applications, including terrain volume measurement, structural assessments, and the creation of detailed base maps.
The newly introduced Ground Control Points manager is a important enhancement within the P2P workflow. This development is part of Blue Marble’s commitment to continuously improve the quality and processing speed of P2P outputs with each software update.
