The Delta Simulation Model II (DSM2) is a hydrodynamic model used for Sacramento-San Joaquin Delta planning and management. When working with DSM2 output, I frequently need to look up the location of channels, nodes, and stations in the model. A map of all of the channels, nodes, and stations (and more) is provided with DSM2 as a PDF file, but that file is not easy to search.
Fortunately, folks in the Delta Modeling Section of the Department of Water Resources shared shapefiles of DSM2 channels, nodes, and stations with me.
In developing the DSM2 HYDRO Viz Tool, we were faced with deciding how to deploy a Shiny app that required interaction with large local files. I first heard about the possibility of using Electron to deploy Shiny apps as standalone desktop applications in this talk by Katie Sasso, but it wasn’t until I discovered the R Shiny Electron (RSE) template that I decided to take the plunge.
R Shiny Electron Build Process The R Shiny Electron (RSE) template includes only very basic instructions for how to get started with this process (and they clearly specify that it is not ready for production).
