Understanding Raster Data in GIS: Pixels, Bands, and Formats | 1 | @GISSchools

In this video, we dive into raster data: what it is, its formats, and how it stores geographic information system (GIS) data. Raster data, unlike vector data, uses pixels to represent surfaces like Earth's photographs or satellite images. Each pixel contains numeric data representing a specific area.

Chapters:

0:20 What is Raster Data?
1:04 Types and Formats of Raster Data
2:02 Bands in Raster Data
3:05 Special Formats like DEM
4:17 Practical Examples: Aerial Photo
5:02 Landsat Data Exploration
8:33 Scanned Topographical Maps
9:37 Digital Elevation Model (DEM)
10:23 Conclusion and Future Analyses

Learn about different bands such as RGB and infrared used in GIS for various analyses and understand how each format influences data presentation and analysis. Stay tuned as we explore practical examples and discuss future applications of raster data in advanced GIS analysis and machine learning.
