Study Notes
Spatial Data and Geographical Data
- Spatial data refers to information that is associated with a particular location or geographic area.
- Metadata in the context of geographical data is information that describes the characteristics of the data, such as its source, format, and accuracy.
Types of Geographical Data
- Linear data is represented as a line on a map, such as roads, rivers, and boundaries.
- Point data is represented by coordinates, which are used to locate a specific point on a map, such as a building or landmark.
Data Collection Methods
- Relief maps are the oldest and most common method of raising the features of the Earth's surface, creating a three-dimensional representation of the terrain.
- Aerial photography is the process of photographing the Earth's surface through a regular camera installed in an aircraft flying at a known altitude.
GPS and Satellite Images
- The Global Positioning System (GPS) is primarily used for navigation, tracking, and mapping.
- There are two famous types of Satellite images: Landsat and Spot.
Census Data
- Census data is collected from internationally approved official censuses and from governmental and non-governmental departments and agencies.
Map Types
- Choropleth maps represent data as colored areas, such as population density or election results.
- Symbol maps give each position a geometric symbol, such as a circle or square, to represent data.
- Isopleth maps are used to display continuous data, such as temperature or elevation, and serve the purpose of showing the distribution and pattern of the data.
