I have a csv file containing information at given lat and lon GPS coordinates, as well as a shapefile containing, among other things, annual average daily traffic (AADT) values along stretches of road in NYC (TDV_Shapefile_AADT_2015.zip from https://www.dot.ny.gov/tdv).
What I'd like to do is create a bridge to map each GPS coordinate in my csv file to the closest AADT value in my shapefile.
Is this possible in QGIS3?
I'm a total GIS beginner.
What I've been able to do so far is upload a sample of my data as a layer onto my shapefile. What I need to do now is obtain match each point with the closest AADT value.
NYDOT has an online tool here using the data from the shapefile I'm using. If you zoom in, especially in NYC, you can see most streets have a color and a value. What I want is to get that value for each point in my csv.
