It takes a little playing with, and a little knowledge, but it works great. Think in basic football terms. Interesting article. Is there a reason that latitude and longitude are given in that order instead of longitude and latitude? Am I reading that incorrectly, or is there a reason for that convention? I have a similar question from Maryland. I have a plot plan that contains reference N: , This is an IPF location.
Any suggestions? I have a set of property drawings of the public bus depot in Rochester, NY done in It shows the coordinates of the corners of the buildings on the property. For example: 49, The longitudinal lines are perpendicular to the equator.
Are the longitudes perpendicular to the latitudes? Your email address will not be published. Skip to content. Latitude and longitude coordinates make up our geographic coordinate system.
Longitude Coordinates. Latitude Coordinates. How can the size of an area delineated by latitude and longitude be calculated? In football, running North-South is to move down the length of the field?!? Very helpful for anyone learning these concepts. Leave a Reply Cancel reply Your email address will not be published. Toggle Menu Close. Latitudes measure an angle up from the equator latitudes to the south are negative.
Figure 1. With an angle of longitude and an angle of latitude, we can locate any point on the surface of the earth. You've seen lines running across maps your whole life and may not have noticed them. The lines running North to South are called "Meridians" or "lines of longitude" Figure 2 , while the lines running East to West are called "Parallels" or "lines of latitude" Figure 3. Figure 2. Meridians or "Lines of Longitude" and degree readings for longitudes in increments of 30 degrees. UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based Transverse Mercator.
The UTM system consists of 60 zones, each 6-degrees of longitude in width. The zones are numbered , beginning at degrees longitude and increasing to the east. The military uses their Changes to UTM values are generally larger, around meters, What is the State Plane Coordinate System? Can GPS provide coordinates in these values? The State Plane Coordinate System SPCS , which is only used in the United States, is a plane coordinate system north-south and east-west lines are perpendicular in which each individual state has between one to six zones, depending on the state's size and shape.
What location coordinates datum does the Geographic Names Information System use? Board on Geographic Names website. Query the database for official geographic feature names, their location attributes, variant names, and other data. Display, print, and download up to 2, records from a query. Board on Geographic Names BGN , which maintains cooperative working relationships with state names authorities to standardize geographic names.
