Once the Meridian Maps team has finished customizing your map and uploaded it to the Meridian Editor, you’ll need to set the map’s scale so that your Meridian-powered app will be able to calculate distances when calculating turn-by-turn directions.
The Meridian Editor uses anchor points to calculate map size. By aligning a map’s anchor points with the Google Maps satellite image of the same location, the Editor can calculate the sizing for the Meridian-powered app’s location and wayfinding features.
If you don’t set the anchor points, the map won’t be to scale.
Set a Map’s Anchor Points
Complete these steps to edit a map’s anchor points to set the map’s scale and offset. Before you can set a map’s anchor points, you’ll need to have a map image for that floor.
- In the Meridian Editor sidebar, click Floors, and then click the Edit Floor icon on the floor with the anchor points you’d like to edit.
- Scroll down to the Map Anchor Points (Reference) section, and then in the Search by address or place name search for the building’s location’s address.
- Click the + button to zoom in until you can easily see the map’s building.
- Click place markers here, and then click and drag the + markers to opposing corners of your building.
Technically, any two points on the map can be used. However, the further your points are from each other, the more accurate the calculation of latitude and longitude will be; the larger the map, the more accuracy gained from the distant between points. Hence the recommendation to use opposing corners.
- In the map view, click and drag the + anchor point markers to match the placement in the satellite view.
- When you’re done positioning the anchor points, click Save.
NORTH OFFSET is a value used to handle variations between true north and magnetic north.
For example, if the main entrance to your map is located at the north of your location, you’d probably want to enter 180 in the MAP NORTH field to rotate the map 180 degrees. This would rotate the map so the main entrance appeared at the bottom of the map.
Map Width (Meters)
The map's width in meters. This is calculated using the map's GPS location and map anchor points.
Map Height (Meters)
The map's height in meters. This is calculated using the map's GPS location and map anchor points.
At certain zoom levels, map elements appear and disappear.
ZOOM SCALAR acts as a multiplier on the default zoom behavior.
It's best to use values between 0.0 and 2.0.
For example, a ZOOM SCALAR of 0.5 would cause the interior walls to fade in at half the zoom level than they would otherwise.
When you zoom in too far, Meridian maps become kind of useless because you can't see anything.
The ZOOM MAX dropdown menu lets you set the maximum zoom permitted for a map.
The ZOOM MAX values are:

Use Control Tags For Asset Tracking
Check the box to enable asset tracking for this map.
This feature is currently disabled. Control Tags can still be used to manually gauge the accuracy of Asset Tracking, but this setting will not affect that accuracy.
