Explain major geographic concepts (location).
Use and interpret geographic information systems (GPS, GIS), remote sensing, and online mapping.

2. Location The position of something on Earth’s surface
Can be expressed as:
Absolute Location
Usually expressed in latitude/longitude, or as a street address (GPS)
Relative Location
Compares one location to that of another using time, distance, direction

3. Absolute Location 30°20’13” N, 81°39’41” W or
30 degrees 20 minutes 13 seconds North, 81 degrees 39 minutes 41 seconds West
Only one coordinate on Earth that matches this latitude/longitude

4. Darnell-Cookman MS/HS of the Medical Arts
1701 North Davis St.
Jacksonville, FL 32209
USA
Only one address like this in the world

5. Relative Location
Describes where a location is in reference to other locations
Usually expressed in terms of distance, direction, and time
For example:
Atlanta is 345 miles (or a 6 hour drive) northwest of Jacksonville

6. Site vs. Situation
Site: the exact location (like absolute location) chosen for a settlement because of its favorable conditions (food, water, defense, trade)
Situation: the area surrounding a settlement, including the closeness to raw materials, other settlements, and trade routes (like relative location)
New Orleans, Louisiana

7. Remote Sensing
Collecting geographic data about Earth from long distance without actually being there
Satellite
Airplane
Drone
Sensors
Infrared imagery of a farmer’s crops helps identify healthy vs. stressed plants

10. Practice - Global Information Systems (GIS)

12. Map Generalization
There is way too much real world data to include all of it on a map (remember, maps are smaller representations of the real world)
Therefore, geographers must simplify the information, usually the most common or prevalent
This forces geographers to leave out a lot of the less common data

13. But what is the map data not telling us?
The map didn’t tell us that there were almost as many babies named “Olivia, Emma and Sophia” the same year in Florida.
In fact, most girls born were NOT named Isabella!!!
