the returned locations of the sensors are way different than the passed boundary locations. I tried nwlng=-121.75,nwlat= 37.42, selng= -114.52, selat=32.55. When I checked the locations of the returned sensors I got selected_sensors[‘latitude’].max(), selected_sensors[‘latitude’].min() = (62.34708, -40.87172). How is this possible? Can you please help?
