Street Layer. Can I turn it off? What about updates/inaccuracies? (And other common questions)

How to make the most of the street layer shown in Terrain Navigator Pro 9.

Introduction

Starting with version 9 of Terrain Navigator Pro, a street layer is available for overlaying on the topographic maps and aerial photos. This allows you to see streets that may have been added or changed since the base map was created (or the aerial photo was taken.) This also allows you to see the street names on the aerial photos.

Version 11 added Street Map (and Outdoor Map) types, which are generated by a different method, and can be merged with topographic maps and aerial photos to create a blended map display.

How was this layer collected and how current is it?
This street layer was provided by the same company that manufactures TomTom GPS units. In fact, the USGS uses this same data to produce their new "US Topo" series of digital maps.

The street layer included with Terrain Navigator Pro is from March 2015. Unfortunately, due to a format change by TomTom, they are unable to provide further updates. Instead, we recommend using the Street Map type, which is constantly being updated and revised.

How do I turn off the street layer within Terrain Navigator Pro?
As with any layer, you will find the ability to show and hide it by opening the View menu and choosing Layer Size/Visibility. In the list of available layers, turn off Streets.

Alternatively, you can use the Layer Size/Visibility button on the toolbar; or even use the show/hide all layers button - to quickly toggle between the base map and the map with the various layers (including streets) overlaid.

When I have the street layer turned on, Terrain Navigator Pro operates sluggishly. Is this normal?
Yes. Due to the amount of processing required, you may see some performance degradation when a complex street system is being overlaid the maps. To improve performance, use the Layer Size/Visibility control in the View menu to turn off unneeded layers.

Can I change the color of the streets? How about the sizing?
The color set is currently preset. We hope to add additional color and rendering options as we continue to revise and improve Terrain Navigator Pro. Sizing, however, can be controlled (globally) using Layer Size/Visibility in the View menu.

One tip regarding sizing: In the Layer Size/Visibility window, un-check the option to "conform layer size to map scale" this will prevent the roads and text labels from sizing larger as the zoom level/scale is increased.
