Today in the class I learnt about Geo position. In the dataset provided in Washington post, there are two columns of latitude and longitude. With these columns we can explore the concept of Geo Position.
Geo position is which specifies a location on the Earth’s surface in terms of latitude and longitude. These coordinates provide a precise and unique identifier for any point on the Earth. Geographic positions are a fundamental concept in geography, cartography, navigation, and geospatial information systems (GIS).
The components of geo position:
- Latitude: Latitude is the angular distance measured in degrees north or south of the equator (0° latitude). Lines of latitude run parallel to the equator, with positive values indicating locations north of the equator and negative values for locations south of the equator. The range of latitude is from -90° (South Pole) to +90° (North Pole).
- Longitude: Longitude is the angular distance measured in degrees east or west of the Prime Meridian (0° longitude), which passes through Greenwich, England. Lines of longitude, also known as meridians, run from the North Pole to the South Pole. Positive values indicate locations to the east of the Prime Meridian, while negative values indicate locations to the west. The range of longitude is from -180° (the International Date Line) to +180°.
With data of latitude and longitude in the dataset, we can explore about Geo position with we can simplify data into the region where the shootings are happening more.
