RELEASE OF RV<strong>6.8</strong> <strong>TNT</strong> PRODUCTS<br />
A Design Scale can now be set for 2D groups for element and style scaling. This is also<br />
usable in the Spatial Data Editor so that elements may be styled as they will appear in a<br />
subsequent layout composition.<br />
2D Geospatial Display.<br />
Mu ltiple Views.<br />
Ge oLocking.<br />
Multiple 2D and 3D views can be opened in all the <strong>TNT</strong> products. If 2D views contain<br />
geodata that covers a common ground area (which means, overlapping extents), they<br />
can be GeoLocked. V6.70 kept the scales of all these views the same if scale locking<br />
was on. Changing the scale of one view caused the other locked views to change to the<br />
same scale and redraw.<br />
RV<strong>6.8</strong> provides 3 choices for how GeoLocked windows should<br />
relate to each other: Scale Only, Extent Only, and Extent and Scale. Locking by Extent<br />
and Scale is the default method of maintaining a common scale and area for all<br />
GeoLocked views. Change the scale in 1 view, and all other views will automatically<br />
redraw to the same scale. The attached color plate entitled GeoLock with Relative<br />
Zoom illustrates uses of these new lock relationships. These new combinations of Geo-<br />
Locks can be preset in a screen layout or in the startup layout of <strong>TNT</strong>atlas. For example,<br />
an atlas can be automatically opened with GeoLocked side-to-side View windows<br />
showing a reference map and an associated image or in some other arrangement using<br />
more than 2 windows.<br />
By Extent Only.<br />
Locking a view by Extent Only means that it may not automatically redraw if there are<br />
scale and position changes in other GeoLocked views. Since scale locking is off, the<br />
relative scale value for this view is ignored, and this view will only change scale using its<br />
own zoom in/out controls. Only other views that are also extent locked can cause this<br />
Extent Only view to change. This happens only if the smaller extent box of another<br />
zoomed in, extent-locked view moves outside the larger extent box of this Extent Only<br />
locked view. If this happens, this Extent Only locked view will redraw to center on the<br />
smaller extent box for the other zoomed in extent locked view. Another extent locked<br />
view can be zoomed out so that it has an extent box that is larger than the Extent Only<br />
locked view. In this case, the Ex tent Only<br />
view will not move, change, or redraw when<br />
the extent box of that larger view is moved about.<br />
Extent Only locking is useful to create a reference view presenting a macro view of a<br />
general area topographic or planimetric map or a zoomed out view of an image. Other<br />
extent locked Views can be opened that are zoomed in on the image. They can then be<br />
zoomed or panned using the Extent Only locked view for reference and it will only redraw<br />
if these detailed views move off the area of the current Extent Only locked reference<br />
view.<br />
By Scale Only.<br />
Locking a view by Scale Only means it will automatically redraw<br />
to maintain its scale<br />
when some other scale locked view is zoomed in or out.<br />
Now you can also set a Rela-<br />
tive Scale value of greater or less than 1.000 for each scale locked view. This value<br />
sets the relative scale to be maintained by this view relative t o other scale locked views.<br />
Setting scale locking on for two or more views, along with appropriate re lative zoom fac-<br />
tors, means that they zoom in and out in tandem at these relative scale s. It is also im-<br />
