** Bug fixes
- referenceEllipsoid.m: express semimajor axis of Everest 1830 in
meters rather than the original 'Indian feet'
- kmlread.m: fix typo when reading Point data
- shapedraw.m: fix erratic (0, 0) coordinates occurring in plots
- shaperead.m: improve reading attributes (bug #61757)
** Code improvements
- referenceEllipsoid: return no output to screen if called with
just 0 (zero) and an output is requested. Abbreviations for a
few ellipsoids were added.
- replace validation of input reference ellipsoids by calls to
sph_chk.m in several tens of geodesy functions. This makes for
a big code reduction but also adds flexibility for inputting
reference ellipsoids and/or reference sphere.

** Bug fixes:
* gpxread.m (bug #58701):
- read milliseconds in Time nodes in Tracks, if present.
Time fields in Waypoint sections are still ignored.
- Various other fixes (missing Ele(vation) and Time nodes,
texinfo help text).
* kmlread.m (bug #58854):
- Accept various mixed time formats.
- Be more flexible regarding missing fields.
Note: kmlread.m is still considered experimental.
Thanks to Geoff Warne for supplying numerous .gpx and .kml
test files and aid in diagnosing issues.
* roundn.m: much improved Matlab-compatibility
* angl2str.m: ditto, thanks to Ricardo Fantin da Costa
* shapedraw: fix some Point geometry plotting logic, return
empty file handle in case of empty shapes
** Code improvements
* distance.m: improve accuracy for small distances
Summary of important user-visible changes for mapping 1.4.0:
-------------------------------------------------------------------
** The mapping package now depends on the geometry and io packages. The
(suggested) dependency on the octclip package has been removed.
** The following functions are new in mapping 1.4.0:

** Bug fixes:
shapedraw.m: * Fix color arg. bug when drawing (poly)line
geometries.
* Restore input check order.
* Do not connect multipoint shapes.
shaperead.m: * Fix reading 'line' geometries.
* Ignore shapes with (almost) infinite
coordinates.
* Fix .shx file usage.
* Move file existence check to start of function.
* Fix reading MultiPoint shapefiles.
* Provision for absent M-values in M and Z
shapetypes.
* More robust input validation.
* Properly process BoundingBox limits.
* Fix incompatible dimensions bug when reading Multipoint files.
* Fix reading selected attributes.
shapewrite.m: * Various fixes (credits to a.o., Martin Kunz, M.Parkan).
* Properly write missing M-values.
* Fix OOM error when writing large Point type files.
* Fix and overhaul writing requested attributes.
Fixes for bug #53422:
* Unconditionally write .dbf file.
* Fix record lengths for all Point types.
* Fix XY coordinate write order for all Multipoint types.
* Update .shx header as well.
rasterinfo.m: Show nr. of bands and bounding box.
** Code improvements
shaperead.m: * Invoke the Clipper library for clipping polylines
and polygons, leading to much improved performance
when invoking the BoundingBox option together with
the Clip option. To use this feature the Octave-
Forge geometry package >= 4.0.0 must be installed
and loaded.
** New features
shapewrite.m: * Allow writing M & Z shape types (Matlab-incompatible
types, yet supported by Octave).
Summary of important user-visible changes for mapping 1.2.1:
-------------------------------------------------------------------
** The following functions are new in mapping 1.2.1:
rasterread
rasterinfo
rasterdraw
gdalread
wrapToPi
wrapTo2Pi
wrapTo180
wrapTo360
** New features
Reading GIS raster data: A first go is provided using
functions rasterread.m and rasterinfo.m. Both invoke binary
function gdalread() of which an initial version was provided
by Shashank Khare. rasterread.m and rasterinfo.m can read
and return info on any raster data type that the underlying
GDAL library can read. As such, separate functions for e.g.,
GeoTIFF and ArcGrid etc. are not required.
To make use of these functions the GDAL library must be
present on your system => GDAL is a suggested dependency.
mapshow.m: drawing raster data is now supported.
shapedraw.m: drawing speed of filled polygons and multipatches
is much improved
wrapTo180.m, wrapTo360.m, wrapToPi.m, wrapTo2Pi.m: Provided
by Oscar Monerris Belda and turned into their present versions
with help of a.o., Andreas Weber
** Bug fixes:
shapewrite.m: correct Lat/Lon mix-up
update overall BoundingBox for Point type
shaperead.m: improve reading Nr. of parts (of Polylines/-gons)
** To avoid shadowing core functions rad2deg and deg2rad, these
functions are only copied into place if Octave (< 4.2) does not
have them.
Summary of important user-visible changes for mapping 1.2.0:

** The function `distance' has been greatly improved with more options
including calculating the azimuth between points and support different
angle units.
** The function km2deg can accept an optional radius or the name of some
Solar System objects.
** Test functions for deg2rad, km2deg and rad2deg have been added.
** Functions shapeinfo, shaperead, shapewrite and shapedraw are meant to
process ArcGIS shape files. Functions mapshow and geoshow are simple
Matlab-compatible wrappers for shapedraw. A basic implementation of
makesymbolspec is also present.
For some functionality of shaperead.m, shapewrite.m and shapedraw.m
the Octave-Forge geometry, io and octclip packages are required.
The shape* functions are considered experimental yet. Only projected
data files can be drawn and several limitations apply. On the other
hand some functionality is present that supersedes ML compatibility.
See the help for each function.
