About Data Usage Calculation
Your data usage is measured in bytes of Nearmap proprietary aerial imagery viewed.
These activities do consume data:
- Viewing a site, zooming in, panning around
- Selecting a date to view from the date dropdown box
- Consuming Nearmap imagery via an integration such as WMS, ArcGIS Online, Tile API and KML (Google Super-overlay)
- Solar reports (typically less than 1MB per report)
These activities do not consume data:
- Panning over the world map at low resolution
- Zooming and panning over an area that is not covered by Nearmap aerial imagery
- Viewing Roadmaps
- Viewing StreetView
Screen Resolution and Data Consumption
The larger your monitor, the more data you use at each step. With a screen resolution of 1024x768 you will typically consume less than a megabyte per virtual site visit. On a larger HD screen (1920x1080 pixels) you will typically consume three megabytes per site visit.
You can reduce your data usage on a large screen by not running your web browser at full screen size.

Confirm the Accuracy of Nearmap's Data Usage Calculations
We regularly audit our data usage calculations, examining server logs in order to determine whether session by session, day by day, correct usage statistics are being stored and shown. It is important to note that all imagery downloaded from our server to your computer contributes to data usage, not just when using the Export function.
Here is how to confirm the accuracy of Nearmap's data usage calculations in Chrome or Internet Explorer:
On a PC, press F12 to bring up the Developer Console in the lower part of the browser window. On a Mac, press Option-Command-I.
Switch to the Network tab to see a status bar on the bottom of the browser window that indicates the data transferred.
If you are using Internet Explorer, you can also reach the developer console using F12. Click the Network tab, then click the Play button to start tracking traffic. The data received is shown on the right side of the bottom status bar.
