Exercise

Prepare to calculate distances

In this exercise you will prepare a GeoDataFrame called art_dist_meters with the locations of downtown art converted to meters using EPSG:3857. You will use art_dist_meters in the next exercise to calculate the distance of each artwork from the center of the Urban Residents neighborhood in meters.

The art data is in your workspace, along with urban_poly_3857 and center_point, the center point of the Urban Residents neighborhood. A geometry column called geometry that uses degrees has already been created in the art DataFrame.

Instructions
100 XP
  • Create a GeoDataFrame called art_dist_meters, using the art DataFrame and the geometry column from art. Set crs = {'init': 'epsg:4326'} since the geometry is in decimal degrees. Print the first two rows.
  • Now explicitly set the coordinate reference system to EPSG:3857 for art_dist_meters by using to_crs(). Print the first two rows again.
  • Add a column called center to art_dist_meters, setting it equal to center_point for every row .
