Calculating distance in a projected CRS
Now we have the Eiffel Tower location in a projected coordinate system, we can calculate the distance to other points.
The final s_eiffel_tower_projected of the previous exercise containing the projected Point is already provided, and we extract the single point into the eiffel_tower variable. Further, the restaurants dataframe (using WGS84 coordinates) is also loaded.
This exercise is part of the course
Working with Geospatial Data in Python
Exercise instructions
- Convert the
restaurantsto the same CRS as the Eiffel Tower point. For this exercise, don't specify theepsgkeyword, but make use of the.crsattribute. - Calculate the distance for all restaurants to the Eiffel Tower.
- Print the smallest distance.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Extract the single Point
eiffel_tower = s_eiffel_tower_projected[0]
# Ensure the restaurants use the same CRS
restaurants = restaurants.____
# The distance from each restaurant to the Eiffel Tower
dist_eiffel = ____
# The distance to the closest restaurant
print(____)
