Features in Atlas
-
Select the map age by name as well as numerically.
-
Use the supplied time scales taken from standard references or
-
Load your own. Simple ascii format used.
-
Create grids akin to latitude longitude but centred on any point (optionally
moving with a plate). This helps to visualize spatial relationships such
as transform faults - you can see whether features are tangential to the
specified pole, etc.
-
Draw new features using the on-screen digitizing on a reconstruction and
have the co-ordinates converted to present day for use at any age.
-
%age flag automatically replaced by current map age in title
-
Pattern fills may now be transparent so that the underlying image can be
seen through the gaps.
-
You can now show ellipses in addition to alpha 95 circles (i.e.. circles
of a given radius in degrees about a point)
-
The pre-select system has been improved and can be updated independently
of the program file. It speeds up plotting by rejecting data for plates
not in the current map window.
-
Zooming in using the mouse can be toggled on & off. Different cursors
show which state is active. You can return to the previous zoom.
-
Data files can be 'dragged & dropped' into the map from other Windows
applications
-
One click button to access attribute settings (alter fill colours, etc.).
Also a new button that allows you to set default attributes for new data
- data tagged with the same value will automatically be assigned the same
default attribute settings.
-
Memory limits expanded or abolished:
-
Objects may now have more than 5000 pts in ATL format. The limit is now
dependent on how much memory is available.
-
The number of rotations and individual plates allowed has been greatly
increased to cope with more detail in the plates and their motion.
-
The Tweak system for interactively adjusting a reconstruction has been
revamped. It is now more robust and allows you apply the modification to
more than one plate at once. Fast screen update option. You can store the
result as a set of Euler poles for use in other maps with other data sets.
-
Backtracking (showing the successive position of a point on a plate with
time either in absolute co-ordinates or relative to another plate) has
been revamped. Values are retained to speed up subsequent tracks.
-
The Sequence command allows you produce maps that differ only in age rapidly.
The maps can be stored as BMP or WMF files or sent to the default print
device. The files can then imported into packages such as PowerPoint, to
produce animations.
