Intermountain GIS Conference

High-resolution imagery is transforming how GIS professionals extract and maintain planimetric data, providing a scalable and consistent approach to mapping features that are traditionally time-intensive to collect in the field. Up-to-date, high-quality planimetric data is essential for infrastructure management, transportation planning, environmental analysis, and public safety.
This presentation explores how high-resolution aerial imagery can be leveraged to derive a wide range of planimetric features, including impervious surfaces, transportation networks, land cover classifications, and detailed pavement markings. We will also examine the practical benefits of imagery-derived datasets, such as improved accuracy, standardized feature attribution, and the ability to detect and quantify change over time.
Real-world examples will demonstrate how agencies are using imagery-derived planimetric data to support stormwater modeling, asset management, transportation safety, and land use planning. By integrating high-resolution imagery into routine GIS workflows, organizations can significantly enhance data quality, reduce collection costs, and build more resilient, data-driven communities.
