# Ortho-Imagery (Raw Data) The **Ortho-Imagery** entity stores a set of georeferenced images—typically aerial or satellite imagery—used for detailed mapping, visualization, or terrain analysis. Add georeferenced aerial imagery with associated world files (e.g., JPG + JGW). Supports bulk uploads via ZIP. → *Ideal for surface visualization and texture mapping.*
