Imagery Layer
A GIS layer containing raster images, such as satellite or aerial photos, used for visualization and analysis.
What does an Imagery Layer represent?
In GIS, a raster-based dataset that shows satellite or aerial photos of the Earth's surface is called an imagery layer. It enables users to view, examine, and understand real-world elements like flora, metropolitan areas, water bodies, and landforms.
Among the essential features of an imagery layer are:
Originating from sources such as airplanes, drones, or satellites
Frequently includes panchromatic or multispectral data.
Suitable for surface analysis, classification, and change detection
Allows for scaling and zooming to examine minute details.
Because imagery layers offer comprehensive, current, and spatially accurate visual information, they are frequently used in disaster management, agriculture, land use planning, and environmental monitoring.

A geospatial dataset made up of high-resolution photos taken by satellites in orbit around the Earth is called a satellite imagery layer. Applications include mapping, environmental monitoring, urban planning, and disaster management are made possible by its provision of comprehensive, current visual data on the planet's surface.
A digital map layer made up of photos taken by drones or airplanes is called an aerial imagery layer. In GIS and mapping applications, it offers a high-resolution, aerial perspective of the Earth's surface, facilitating precise landscape, infrastructure, and natural feature visualization, analysis, and interpretation.
Users can view and examine continuously changing data, such as satellite photos, drone feeds, or weather patterns, by using a dynamic imaging layer, a kind of geospatial data layer that updates in real-time or almost real-time. By displaying the most recent conditions on the map, it facilitates interactive mapping, monitoring, and decision-making.
A cloud-based geospatial service that saves and makes available raster imagery—such as satellite or aerial photos—for analysis and visualization is called a hosted imagery layer. Without having to handle the underlying data locally, it enables users to quickly access, stream, and overlay high-resolution photos in GIS applications.
