Imagery Layers can be used for so many different things, and there are countless ways to work with your imagery data. Hosting imagery in ArcGIS Online allows you to easily visualize, analyze, and share your data with others. With so many possibilities, it can feel overwhelming to know where to begin. So, let’s start by answering two key questions: what are Imagery Layers, and which one should you choose for your data and goals?
What are Imagery Layers?
In simple terms, Imagery Layers are raster data, whether it be from satellites, drone imagery, or elevation models of the earth’s surface. All these different data sources can be hosted or shared in ArcGIS Online as either a Tiled Imagery Layer or Dynamic Imagery Layer. The type of layer you choose will depend on what you want to use your imagery data for, and how you want to use the data you have. And this is just the start! Don’t worry, we are here to help you figure out the best course of action for your needs.
