Version 2.0.1 (R13SP1+) Mapping Toolbox™ Software Release Notes

Version 2.0.1 (R13SP1+) Mapping Toolbox Software

This table summarizes what's new in Version 2.0.1 (R13SP1+):

The new feature introduced in this version is

mapexreg Demo (Georeferencing an Image to an Orthotile Base Layer) Generalized and Clarified

Calls to imtransform and makerefmat are no longer hard-coded for an output pixel size of one meter. The choice of output pixel size now is explained in detail.

Fixed Bugs

Version 2.0.1 contains the following bug fixes:

almanac

Function almanac now gives a precise inverse flattening (1/f) value for Bessel 1841 ellipsoid. Previously, almanac used a truncated value (299.1528) instead of the full precision value (299.1528128).

axesm

Function axesm now accepts the 'meridianlabel' parameter. Previously, axesm would throw an error if the 'meridianlabel' parameter was specified.

distance

Function distance now computes correct results for rhumb line distances along a parallel (including the equator) on a (nonspherical) ellipsoid.

distance

Function distance now uses the robust "aversine formula" to compute great circle distances on a sphere. For certain inputs roundoff sensitivities in the previous implementation resulted in a small, but nonzero, distance between identical points.

distance

Function distance now correctly obtains correct results for rhumb lines that follow the equator, or any other parallel, and cross the 180-degree meridian; it gives the distance along the short arc of the parallel. Previously the length of the long arc could be returned instead.

distance, azimuth

Functions distance and azimuth now produce accurate results even for long geodesics on an ellipsoid, up to near-antipodal distances.

projfwd, projinv

Functions projfwd and projinv now use NaN separators on all platforms. Previously, under certain circumstances, projfwd and projinv returned coordinate arrays with Inf separators rather than NaNs.

reckon

Function reckon now supports geodesics on an ellipsoid, in addition to rhumb lines on an ellipsoid and both geodesics and rhumb lines on a sphere.
