About Me

Frank L. Engel

I'm a geographer and researcher at the U.S. Geological Survey with over a decade of experience developing innovative tools, technologies, and applications using remote sensing to address real-world water resource challenges.

My development work focuses on the operational deployment and standardization of image velocimetry and near-field remote sensing technologies within USGS — a domain where I have developed the first successful operational implementation at national scale and continue to lead as the agency's primary subject matter expert.

What I Do

My work is national in scope and cross-disciplinary, spanning:

  • Hydrologic remote sensing — using cameras and video to measure river flow
  • Software development — building operational tools for field scientists
  • Cloud infrastructure — designing scalable systems for imagery data
  • Training and capacity building — teaching non-contact methods to 170+ USGS staff
  • Policy and standards — authoring the first USGS procedures for image velocimetry

I operate independently, leading projects from concept through deployment and often serving as principal investigator, lead developer, project manager, and trainer across multiple concurrent projects.

v1.5.0.0

Welcome to IVyTools v1.5 🎉

This is a major update bringing interactive lens correction, smarter search line handling, improved velocity visualization, and friendlier error reporting. Here's the highlights:

Plus: improved orthorectification for portrait/oblique cameras, add/remove GCP rows directly in the table, documentation migrated to MkDocs, and numerous bug fixes for units, uncertainty, and project loading.

Tip: Existing v1.x projects will load normally. Reprocessing is recommended to benefit from the search line clipping and ortho improvements. Older projects using 3D rectification will need to be review, as the new 3D method will be slightly different (XS will move).

Full details in the v1.5.0.0 Release Notes.
