Generating geographical coordinates from giver corner

Based on the given corner in the map(position A), I want to generate more coordinates towards position B by adding some small values (distances) in the given latitude and longitude. For instance:

  • There are 6 houses from position A to B in a map. If I know the latitude, Longitude of 1 house ( 143.5689855, -38.328956999999996), how can I create the coordinates for the remaining 5?
  • I tried to achieve this by adding some small numbers in coordinates of a given corner as shown in below script. But the code only output for 1 house. How can I create a loop in my code that will automatically add the given small number and displays new coordinates for the rest of houses or even for bigger area?

What I have tried:

from arcgis.gis import GIS
from arcgis.geocoding import geocode
from arcgis.geocoding import reverse_geocode
import pprint

# Create an anonymous connection to ArcGIS Online
gis = GIS()


#45-Stodart-St (given corner)
geocode_home = geocode(address="45 Stodart St, Colac VIC 3250")
location = [geocode_home[0]["location"]['x'], geocode_home[0]["location"]['y']]
pprint.pprint(location)


#Add some small numbers in origanal location. This will give us coordinates of next house i.e 43-Stodart-St

#43-Stodart-St

new_loc = [location[0]+0.0002215*1,location[1]*0.999999]

pprint.pprint(new_loc)

Output:

Solution

  • Assuming you have the 2 locations of house A and house B as loc_A and loc_B. Assuming you know the house numbers of A and B. --> You know the number of houses.

    The following code will iterate over the house numbers and create a list of locations:

    longitude_diff = loc_B[0] - loc_A[0]
latitude_diff = loc_B[1] - loc_A[1]
house_locations = []

for i in range(1, house_number_B - house_number_A):
    house_locations.append([loc_B[0] + i * longitude_diff/(house_number_B - house_number_A),
           loc_B[1] + i * latitude_diff/(house_number_B - house_number_A)])
