Applications of Aerial Survey and Remote Sensing Map Data

In coordination with the Forestry and Nature Conservation Agency’s forest resource surveys and the re-evaluation of working circles, land cover type updates are carried out on a map sheet basis for national forest working circles as well as public and private forest lands. In line with the progress of aerial photography operations, map sheets with outdated imagery are selected for update, and the latest stereoscopic aerial image pairs are produced. Forest land cover data from the resource surveys are overlaid on these stereoscopic images. Areas of change are then identified, interpreted, delineated, and digitized. After compilation and analysis, the updated results not only refresh the land cover datasets but also facilitate the monitoring of forest area changes, providing essential information for land management and decision-making.

To preserve and strengthen staff expertise in image interpretation and its applications, a multifunctional platform centered on stereoscopic image viewing has been developed. This platform integrates interpretation-related datasets, publications, and other outputs from the Branch’s operations, serving as a comprehensive repository of interpretation knowledge and a hub for experience sharing. The database undergoes annual maintenance and expansion to ensure the continuity and advancement of image interpretation expertise, supporting long-term knowledge transfer.

Aerial Photo Interpretation Knowledge Platform - Training Classroom

To strengthen the professionalism of aerial photo interpretation personnel and enhance operational quality and standardization, the Aerial Photo Interpretation Competency Standards have been established. Through a systematic analysis of core tasks within the interpretation workflow, these standards clearly define key competency elements, including behavioral indicators, work outputs, professional knowledge, operational skills, and required attitudes. These standards serve as the foundation for developing training programs, evaluating learning outcomes, and certifying personnel qualifications. They support the institutionalization of training and certification mechanisms, enhance the professional capabilities and execution skills of interpretation staff, and promote the rational deployment and sustainable development of specialized talent.

The VQ-1560 II-S airborne LiDAR scanner used by this Branch measures the distance between the aircraft and ground features using laser pulses, enabling rapid acquisition of high-resolution, high-accuracy three-dimensional spatial data. The resulting point cloud data is widely applied in areas such as national land monitoring, forest resource surveys, disaster prevention, and smart city development, providing critical scientific support for government planning and policy-making.
