Understanding Raster and Vector Overlays on the Map
A guide to understanding and using raster and vector overlay map layers in Phygii.
What Are Overlays?
Overlays are additional data layers that appear on top of the map for a specific location. They give you richer context about a property beyond what the base satellite map shows. There are two types: Raster Overlays and Vector Overlays.
Raster Overlays
A Raster Overlay is an image layer placed directly over the map at a precise geographic position. The most common example is an orthomosaic — a detailed aerial photograph stitched together from drone imagery. This gives you a highly accurate, up-to-date top-down view of a property that may be more current or detailed than the base satellite map.
Raster overlays are useful for seeing the exact layout of a parking lot, roof, or property boundary at a specific point in time.
To view raster overlays for a location, open the location detail page and click the Raster Overlays tab. You can also toggle raster overlay layers on and off from the map view.
Vector Overlays
A Vector Overlay is a GIS data layer made up of shapes, lines, and zones drawn over the map. Examples include property boundary outlines, parking lot section markings, or zone designations.
Vector overlays help you understand the structure and layout of a property in more detail. They can highlight specific areas that are relevant to inspections or maintenance planning.
To view vector overlays for a location, open the location detail page and click the Vector Overlays tab.
Toggling Overlays on the Map
When viewing a location on the interactive map, you can turn overlay layers on and off using the layer controls. This lets you choose exactly what information is visible on the map at any given time.
