# Coverage Map

> Use the Coverage Map filters, layers, and on-map notices without technical jargon.

The page title is **Coverage Map**.

## What the coverage map shows

The coverage map summarizes how activity or attention is spread across the map in **cells** (regions) that change with zoom. It helps you see which parts of your area have stronger signal and which are light or empty, at a glance. Exact coloring and legends follow the labels and key shown on your live map.

## Controls

* **Filters**: opens the **Filters** card. Apply date range, device selection when your workspace uses it, and other options your organization has enabled.
* **Refresh**: reloads coverage for the current map view and filters.
* **Layers**: same **Layers** panel as other map pages (visibility, opacity, ordering). See [Pin Map](/maps/pin-map).

The on-map toolbar provides the same navigation aids as the other map pages: search, home extent reset, basemap switcher, fullscreen, and a scale bar. See [Pin Map](/maps/pin-map) for details.

## Selecting a cell or feature

Click a coverage cell to highlight it and open a popup with its summary numbers. Use **View details** in the popup (when available) to open the feature details drawer for the full breakdown.

Click a GIS reference feature to highlight it and inspect its attributes the same way. Click an empty area of the map or close the drawer to clear the selection.

## Messages at the top of the map

You may see an amber or red banner with a short message. In user terms:

* **Area too large**: you are zoomed out too far for the finest summary. **Zoom in** or wait for the app to try a coarser summary. Some messages explain that a fallback resolution was used or that even a coarser view was still too large.
* **Failed to load**: a temporary or connectivity problem. Try **Refresh**. If it keeps happening, use [Troubleshooting](/support/troubleshooting).
* **Incomplete results**: you may see text such as **Results may be incomplete. Zoom in for more detail.** Zooming in narrows the area and can show a fuller picture.

Data freshness follows what your organization loads into the dashboard. The map does not show internal job schedules or pipeline timing.

## Layers

Reference layers behave like the [Pin Map](/maps/pin-map) layers panel. They do not change the meaning of the coverage cells, but they help you orient streets, boundaries, and other context.
