title: How to identify if a latitude/longitude is within a building r not?
body: <p>I have a set of latitude and longitude points and I would like find if the coordinate exists within a building or not (whether it is indoor point or not). Points could be anywhere within US. I would like to find the Shape File that could help me solve this problem.</p>
  
  <p>I tried downloading shape-files from <strong>www.census.gov/</strong> but it does not have any documentation on the granularity of shape-files it does contain. So I am not able to correctly pinpoint on the right set of shape-files I can use</p>
  
  <pre><code>import geopandas as gpd
  from shapely.geometry import shape
  from shapely.geometry import Point, Polygon
  import pandas as pd
  
  p1 = Point(32.999231, -96.773696)
  
  data3 = gpd.read_file(fp)
  
  data3['geometry'].intersects(p1)
  data3['geometry'].contains(p1)
  </code></pre>
  
  <p>Final output is Indoor/Outdoor. Need some info on the shape files I can use for this kind of problem.</p>
