Thank you in advance for any advice you might give me. I am new to qgis and believe what I'm asking is probably fairly basic. 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?
Thanks so much for any links, resources or explanations that might lead me to answering these questions
