Map of California Focused on Sacramento

The different layers were sourced from several websites. From https://hub.arcgis.com/ I found the river layer and city layer by searching through the website. I got the file with the state’s outline from https://gis.data.ca.gov/search?collection=appAndMap&layout=map&tags=CAOpenData. And finally I acquired the elevation data from https://www.earthdata.nasa.gov/sensors/srtm.
