Improvement to Functions usamap and worldmap
In the functions usamap and worldmap the axes are initialized with a spherical Earth
model having a radius of 6,371,000 meters rather than with a unit sphere, making 3D
viewing more robust. The options 'all' and 'allequal' are now equivalent. In future
releases 'allequal' will be removed.
Compatibility Considerations
This radius change affects the X and Y limits of the axes. If you are setting the
CameraPosition, CameraTarget, CameraUpVector, or CameraLightPosition
properties of the axes with hardwired values determined in releases prior to R2012a,
then you need to multiply the first two elements (X and Y values) by 6,371,000. Likewise,
if you are using the XLoc or YLoc properties to position a scaleruler, you need to multiply
their values by 6,371,000.
To opt out of this change, set the value of the geoid property as in the following code:
worldmap world
setm(gca,'geoid',[1 0])
or
ax = worldmap('world');
setm(ax,'geoid',[1 0])
WMS Database Modified
The WMS Database changes on a release-to-release basis, as some new servers are
added and other servers are removed because they are no longer online or because their
availability is too sporadic. A total of 265 servers (2.75% of the number of servers listed
in R2011b) and 13,505 layers have been removed from the database. A total of 29 new
servers, with 3,589 layers, have been added. The new database contains a total of 9,396
servers and 87,230 layers.
