I am brand new to mapping. I work in a hospital and I'd like to plot 55 sites of pedestrian and bike accidents onto a map of brooklyn (so we can see patterns and consider interventions). Most of my data is intersections, not addresses, plus zip.
How can I turn this into a map?
The data comes from our trauma registry, it is not public. it is in an excel sheet. i don't know what shapefiles or tabular means! it's just street addresses and interactions.
I'd like to make an online map. I got to this site from Carto and didn't realize it was separate.
