Welcome to OpenRiverCam documentation and tutorials

OpenRiverCam is a fully web-based solution for setting up maintaining river observation sites for river flow monitoring with cameras. The software’s backend is based on Large-Scale Particle Image Velocimetry (LSPIV), and geographical orthprojection methods. With affordable camera equipment and a single field survey, you can start monitoring river flows. Software can be deployed locally or on your home server, or be used through deployment in the cloud. Its user-friendly web interface can be accessed via smartphone, tablet, laptop, desktop, all in a simple browser.
