I am trying to map policing activity in NYC for two areas: one area in the Bronx and another in Manhattan.
I want to display ALL of the activity but only WITHIN a couple of square blocks that I am interested in (not the whole precinct - which I have a shapefile for with boundaries already set). My assumption, is that I create a polygon outlining the block areas I want.
But then, how do I attach those boundary coordinates to my CSV database on police activity (that dataset has x y coordinates representing police activity)?
And then, how do I only display the activity within the boundaries rather than all of the activity that exists throughout NYC?
