  • Scale and Zooming

    The data is on map layers and becomes visible or selectable depending on map scale (zoom factor). The bigger the map, the more detail you see. Some layers are only available at certain scales. For instance, you need to zoom in to see parcels and zoom out to see major streets and routes. The legend to the left of the map adjusts automatically to show the layers available at the current scale. A check mark next to the layer name indicates that the layer is being displayed. You can check boxes to add layers and un-check them to remove layers.
