Hybrid aerial mapping

Abstract

This article addresses hybrid aerial mapping, a topic involving the combination of aerial data sources or acquisition methods to produce useful geospatial information. Aerial mapping supports surveying, planning, infrastructure management, environmental observation, and the creation of current map products. Combining complementary methods can help balance coverage, detail, efficiency, and accuracy, depending on the requirements of a project. The resulting workflow needs consistent georeferencing, appropriate quality checks, and careful handling of differences between datasets. Digital photogrammetry, remote sensing, and GIS tools can help transform collected imagery and measurements into orthophotos, elevation products, or other spatial datasets. The value of a hybrid approach depends on matching the acquisition strategy to the intended use and making the limitations of each data source clear. The topic reflects the continuing development of geospatial production workflows as sensors and processing technologies evolve.
