Chapter 1 Flashcards
what is the difference between geography and history?
history answers the “when and why” question whereas geography answers the “where and why “ question.
what is contemporary human geography?
the scientific study of where people and activities are found across earth’s surface and the reason why they are there.
What are the 2 basic concepts to explain why every place is unique? describe them.
- Place: specific point on earth distinguished by specific characteristics.
- Region: an area of earth defined by one or more distinctive characteristics.
what are 3 concepts to explain how different points are related?
- scale: relationship between the portion of earth being studied and earth as a whole.
- Space: physical gap/interval between objects.
- connection: relationship between people and objects across space.
geographers are concerned with _____
global scale
geographers and concerned with the various ______
means that connections occur
what is the geographic information science (gis)
analysis of data about earth acquired through satellite and other electronic information technologies.
what 4 points does the geographic information science provide?
1- helps determine if relationships between objects are related of coincidence
2- captures, stores, queries, and displays geographic data.
3- produces maps that are more accurate/attractive
4- helps measure changes of characteristics over time.
what is photogrammetry?
the science of taking measurements of surface from photographs
what is remote sensing?
acquisition of data about earths surface from a satellite orbiting earth or tore methods.
what is the global positioning unit (gps)?
system that determines the precise position of something with satellites, tracking stations, and receivers.
what is geotagging?
the identification and storage of a piece of info by its precise latitude and longitude.
what is participatory GIS?
community-based mapping, representing local knowledge and information.
in geography, what is a mashup?
map that overlays data from one source on top of a map provided by a mapping service.
what is a map scale and what ways was it presenting?
relationship between size of an object on a map and the size of the actual feature on earth’s surface. presented in ratio, description, or barline.
what is projection?
system used to transfer locations from earths surface to a flat map.
what are the four major different methods for projection? what do they do?
- mercator projection: very little shape and direction distortion, relative size is distorted and causes the high latitudes to look better.
- Gall-peters: distorts shape, not relative size
- Goode homosline: separates E and W hemispheres in 2, known as interruption
- Robinson: allocates lots of space for oceans, land becomes smaller.
what are the 4 types of distortion that can happen on a map?
shape, distance, relative size, direction.
for latitude and longitude, which in natural and which is a human creation?
latitude: natural
longitude: human creation
what is the geographic grid?
imaginary arcs drawn in a grid pattern on earths surface
what is the difference between meridian and parallel?
meridian: arc between N and S poles. related to longitude
parallel: circle around globe to the equator. related to latitude.
what is the prime meridian?
the meridian at 0 degrees longitude that passes through the royal observatory in greenwich England.
