1. Calculating Latitude and Longitude in NYS
Today’s Objective:
(ESRT pg 3)
Think . . .
In what hemispheres can New York State be found?

2. Degrees latitude are labeled on the right and left side of the map.
** Notice that these numbers are all in the 40’s
Is NY north or south of the equator?
* All of these numbers are oN
Degrees latitude are labeled on the right and left side of the map.

3. Using a ruler connect the latitude lines from 41ON to 45ON

4. Degrees longitude are labeled on the top and bottom of the map.
** Notice that these numbers are all in the 70’s
Is NY east or west of the Prime Meridian?
* All of these numbers are oW
Degrees longitude are labeled on the top and bottom of the map.

5. Using a ruler connect the longitude lines from 73ON to 79ON

6. Look for Ithaca, NY. The latitude is more than 42°N but less than 43°N

7. Look for Ithaca, NY. The longitude is more
77°W
76°W
Ithaca
The longitude is more
than 76°W but less than 77°W

8. See these 2 marks . . . They are half way (30’) between 42°N and 43°N.
Let’s draw in the 30 minute (30’)line. Using a ruler, connect them.
The line you just drew is 42°30’N.

9. Minutes (‘) in Latitude
45’
30’
15’

10. Now lets try longitude, See these 2 marks . . .
They are half way (30’) between 76°W and 77°W
Using a ruler, connect them.
The line you just drew is 76°30’W

11. Minutes (‘) in Longitude
45’
30’
15’

12. Now let’s see if we can locate Ithaca more precisely. . .
First comes latitude.
Notice that Ithaca is just south of the 42°30’N line,
If it’s not quite 30’ then we round to 25’.
Ithaca is located 42°25’N.

13. Notice that Ithaca is located right on the 76°30’W line.
Then comes longitude.
Notice that Ithaca is located right on the 76°30’W line.
Ithaca’s longitude is 76°30’W

14. Now put latitude and longitude together to give a precise location:
Ithaca is 42°25’N , 76°30’W.

15. Let’s find the location of Plattsburgh, NY to the nearest minute.
Plattsburgh is about 44°40’N, 73°25’W.

17. Use your ESRT’s to write the location or coordinates for the following
43°05’N, 76°05’W _________________
42°N, 74°25’W ___________________
40°55’N,72°40’W _________________
