Raster vs Vector Data: The Ultimate Guide @gisconnect Chapters 00:00 Topic Overview 03:06 GIS Data Types 07:28 Vector Data Model (Point, Line, Polygon) 16:48 Practical Example of Vector Data (ArcGIS) 18:00 Raster Data Model 22:56 Concept of Spatial Resolution 27:48 Discrete vs Continuous Phenomena in GIS a. Spatial or Geospatial or Geographic Data: - Represents the physical location and shape of geographic features. - It is divided into two main types: 1. Vector Data: - Represents geographic features with discrete shapes. - It has three main types: - Points: Represent specific locations (e.g., the location of a city). - Lines: Represent linear features (e.g., roads, rivers). - Polygons: Represent areas (e.g., lakes, land parcels). 2. Raster Data: • Represents geographic features as a grid of cells or pixels. • Each cell has a value representing information such as elevation, temperature, or land cover. • Examples include satellite imagery and digital elevation models (DEMs). b. Attribute Data: • Descriptive information about the spatial features. • Stored in tables and linked to spatial data. • Provides additional details about spatial features, such as name, type, population, or any other relevant information. #spatialdata, #vectordata, #rasterdata,#attributedata,#GIS,#GISCourseforbeginner,#GISdata
