On the map in the record editor of the Fulcrum web app there are a series of button in the upper-left corner of the map. Additionally, there is a search box in the upper-right corner.
Zoom in and zoom out buttons
These buttons can be used to zoom in or out on the map. You can also use your wheel on your mouse to zoom in and out.
Center on your location
Clicking on this button will center the map view on your location. You should see a blue marble on where you are located on the map. Note that this requires the location settings to be enabled on your web browser.
Zoom to data extent
Clicking this button will zoom out to a level where all the records that have location data can be viewed. If your data is over a large geographic area then the zoom will be pretty far out. If your data is over a small geographic area then the zoom will be at a deeper zoom level.
You can type in an address or place to view the location on the map within Fulcrum. This search is powered by Google.
