Hydrologists are used to jumping through hoops to access data. But it doesn’t have to be that way all the time! In a single semester, the stellar Tecnológico de Monterrey (ITESM) WaterFront Project Team developed software that will easily display monthly summaries of streamflow at multiple USGS stream gages. As a bonus, we can quickly […]
In Spring 2023 the GaugeCam team at the University of Nebraska worked with two excellent student groups on their capstone projects in the Departamento de Computación and Escuela de Ingeniería y Ciencias at Tecnológico de Monterrey (ITESM). The first group we are featuring is the KOLA Data Portal Team. These students did an amazing job […]
There are six key components to be concerned about when setting up the GaugeCam octagon calibration target in the field. As you might guess, based on the bold text above, we are focusing on the last two items in this blog post, which are both related to the size of the octagon in images to […]
We had a great online and in-person audience for Ken Chapman’s dissertation defense on Thursday May 8, 2023. Ken gave an excellent overview of his dissertation, as shown below. He will graduate in December 2023. Congratulations Dr. Chapman! A pdf of Ken’s presentation is available here. Ken’s three major dissertation projects have resulted in a […]
Research: We monitored water quality in the Nebraska Sandhills, combining water sampling with time-lapse imagery from multiple cameras, including two co-located Platte Basin Timelapse cameras. The USGS 104b program supported this project. The animation below illustrates changing water color with changing dissolved organic carbon (DOC)* measured in water samples. At the Kearney Outdoor Learning Area […]
The GaugeCam (GRIME Lab) team, including PI Troy Gilmore at University of Nebraska-Lincoln and Mary Harner at the University of Nebraska at Kearney, have been using imagery in eco-hydrologic studies and science communication for about a decade. The University of Nebraska is also home to a large time-lapse image archive from high-resolution (DSLR) cameras deployed […]
Since 2010, the GaugeCam team has been working on open-source software for ground-based time-lapse imagery (recently referred to by a colleague as “camera trap hydrology”). The project started in François Birgand’s lab at North Carolina State University. GaugeCam was my undergraduate research project and Ken Chapman wrote the open-source software to measure water level in […]
Today I wrote a long email to a colleague interested in setting up GaugeCam. Why not share (a lightly-edited version) with the world?! First, here’s a recent animation of me installing a target. This might take a moment to load. Second, there are a number of additional resources available at https://gaugecam.org/grime2-details/, including this document that […]
