Geography - Its Nature and Perspectives
Term | Definition |
---|---|
Cartography | The art and science of mapmaking |
Choropleth Map | Uses various colors, shades of one color, or patterns to show the location and distribution of spatial data |
Cartogram | The sizes of countries are shown according to some specific statistic |
Cartographic Scale | Refers to the way the map communicates the ratio of its size to the size of what it represents |
Conic Projection | Lines of longitutde converge and lines of latitude are curved. Size and shape are both close to reality |
Distortion | A misrepresentation in either size, shape, or distance |
Dot Distribution Maps | Used to show the specific location and distribution of something across the territory of the map |
Formal (Uniform) Region | United by one or more traits, such as physical, cultural, or economic |
Functional (Nodal) Region | United and organized around a focal point and are defined by an activity that occurs across the region |
Geographic Information Systems (GIS) | Computer system that can store, analyze, and display information from multiple digital maps or geospatial data sets |
Global Positioning System (GPS) | Uses the locations of multiple satelites to determine and record a receiver's exact location |
Graduated Symbol Maps | Uses symbols of different sizes to indicate different amounts of something |
Isoline Maps | Uses lines that connect points of equal value to depict variations in the data across space |
Locator Maps | Show illustrations used in books and advertisements to show specific locations mentioned in the text |
Map Projection | The process of showing a curved surface on a flat surface |
Map Scale | The relationship between a distance on a map and the corresponding distance on the Earth |
Mental Map | Maps that people create in their minds based on their own experience and knowledge |
Mercator Projection | Directions are shown accurately with lines of latitude and longitude shown at right angles. However, land masses near the poles appear large |
Pattern | General Arrangements of things being studied |
Peters Projection | The sizes of land masses are accurate, but shapes are inaccurate, especially near the poles. |
Physical Maps | Shows and labels natural features, such as mountains, rivers, and deserts |
Plat Maps | Shows and labels property lines and details of land ownership |
Political Maps | Shows and labels human-created boundaries and designations, such as countries, states, cities, and capitals |
Processes | The repeated sequences of events that create patterns |
Reference Maps | They are designed for people to refer to for general information about places |
Region | A space that is divided into a smaller areal unit |
Regionalization | The process geographers use to divide and categorize space into smaller areal units |
Remote Sensing | Use of cameras or other sensors mounted on aircraft or satelites to collect digital images of the Earths surface |
Road Maps | Shows and labels highways, streets, and alleys |
Robinson Projection | No major distorations and the oval shape appears like a globe, but the area, shape, size, and direction are all distorted |
Scale | The ratio between the size of things in the real world and the size of those same things on the map |
Scale of Analysis | Used by geographers to analyze relationships among and between places to reveal important spatial patterns |
Scale of Data | Used by geographers to analyze relationships in data |
Spatial Scale | The exent of an area at which a phenomenon or a process occurs |
Thematic Map | Shows spatial aspects of information or of a phenomenon. |
Topographic Map | Shows points of equal elecation that are connected on the map, showing contours that depict surface features. |
Vernacular (Perceptual) Region | Defined by the informal sense of place that people ascribe to them |
