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

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.

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

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.

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

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

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

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.

Minutes (‘) in Latitude 45’ 30’ 15’

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

Minutes (‘) in Longitude 45’ 30’ 15’

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.

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

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

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

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 _________________ Rochester, NY ___________________ Oswego, NY _____________________ Mt.
