FAQ (Frequently Asked Questions)
GIS works by integrating various types of data, both spatial and attribute, into a digital system. It uses specialized software to store, manipulate, analyze, and display geospatial data. GIS software enables users to create maps, perform spatial analysis, query data, and generate reports or visualizations based on the data's geographic relationships.
-Vector (Point, Line and Polygon)
-Raster (Image and Grid)
Non-spatial Data: Non-spatial data, also known as attribute data or descriptive data, refers to information that provides additional context or characteristics about the spatial features. It describes the attributes or properties associated with the spatial data but does not inherently possess any spatial coordinates. Non-spatial data can include various types of data, such as textual descriptions, numeric values, categorical classifications, or any other relevant information related to the features. It is typically stored in tables or databases and can be linked to spatial data through unique identifiers. Non-spatial data is crucial for understanding and analyzing the attributes, relationships, and behaviors of geographic features in a GIS.
Raster data represents spatial information as a grid of cells or pixels of imagery, where each cell contains a value representing a specific attribute or property. It is used to represent continuous phenomena or surfaces, such as elevation, temperature, or satellite imagery.
