20060831: version 0.9.2 * fixed several bugs in drawlsmask method. * removed buggy optimizations for cylindrical projections not crossing the Greenwich meridian. * can now specify map projection region by setting width and height in projection coordinates (in meters) instead of specifying lat/lon of upper right and lower left corners. 20060727: version 0.9.1 * make sure llcrnrlat and llcrnrlon are not at poles for mercator. * use Eric Firing's new quiver in Basemap quiver method. * interp functions now work with masked arrays. * added some sanity checks for projection parameters. * change from classic to new-style classes. * removed deprecated 'createfigure' method. * fixed some creeping numpy'isms (which caused breakage when numarray or Numeric were used). 20060609: version 0.9: * updated for new matplotlib aspect ratio handling. Now maps will always have the correct aspect ratio. * if resolution keyword is set to None when Basemap instance is created, no boundary data sets are needed (methods to draw boundaries, like drawcoastlines, will raise an exception). * update to proj4 module - renamed pyproj to avoid conflicts with proj4 module from CDAT. * createfigure method deprecated, since maps will now automatically have the correct aspect ratio. * Added new projections Xpstere, Xplaea, Xpaeqd (where X can be n or s). These are special-case, polar-centric versions of the stereographic, lambert azimuthal equal area and azimuthal equidistant projections that don't require you specify the lat/lon values of the lower-left and upper-right corners. * fixed bugs in plot, scatter and mapboundary methods for miller, cylindrical and mercator projections. * 'crude' and 'low' resolution boundary datasets now installed by default. basemap_data package now only needed for to get 'intermediate' and 'high' resolution datasets. * moved all packages under single lib/ directory so setuptools' "develop" command works properly. * Added sinusoidal projection. * bilinear interpolation routines can return masked arrays with values outside range of data coordinates masked. * New examples (warpimage.py - warping an image to different map projections, polarmaps.py - simplified polar projections, garp.py - 'World According to Garp' maps). * pcolormesh method added. * drawlsmask method added for masking oceans and/or land areas. 5 minute land-sea mask dataset added. 20060222: version 0.8.2: Minor bug fixes, mostly in examples. 20060203: version 0.8.1: Huge speedups for numpy (no significant differences for Numeric and numarray). 20060114: version 0.8: added numpy compatibility 20051118: version 0.7.2.1: There was a problem running examples that read pickle files. The pickle files were created with numarray, and the data would not be read correctly using Numeric. Fixed so that pickles are created with Numeric and Numeric is used to read them. 20051018: version 0.7.2: * No longer requires numarray (interp function no longer uses numarray.nd_image). * Modified to work with the new ContourSet returned by contour and contourf. * Axes frame turned off by default for non-rectangular projections ('ortho','robin' and 'moll'). * Added createfigure method to create a figure with the same aspect ratio as the map using pylab.figure. * Resets subplot.params defaults so that default axes rectangle will have both a width and height of 0.9 (this ensures that the figure size determines that aspect ratio of the plot). * readshapefile method raises an exception if the vertices look like they are not in geographic (lat/lon) coordinates. 20050921: version 0.7.1: Fixed several bugs in meridian/parallel labelling and Cylindrical projections that crossed greenwich were not being handled properly. Added 'fmt' keyword arg to drawmeridians and drawparallels (default is '%g'). Fixed bug in 'readshapefile' that prevented boundaries from being drawn for 'cyl','merc' or 'miller' projections when the map region did not cross the greenwich meridian. Modified imshow method so 'origin' keyword is accepted (it was always set to 'lower' previously). Added testgdal.py example showing how to plot raster geospatial data with gdal module (gdal.maptools.org). Meridians and parallels labelled correctly when rcParams['text.usetext']=True. 20050914: version 0.7: Optimizations to reduce the time it takes to create a Basemap class instance - now nearly 4 times faster when using resolution='i'. Added 'h' (high) resolution boundary data. Added datasets for major rivers, "drawrivers" class method. Fixed some errors in boundaries datasets. Boundary datasets now installed in a separate package. Should now handle Numeric to numarray conversions internally, so removed warning when rcParams['numerix'] != 'numarray'. Changed default area_thresh so it depends on coastline resolution (10000 for 'c' declining to 10 for 'h'). 20050901: version 0.6.2: Warning issued if numerix = 'Numeric' (a user reported crashes due to botched Numeric --> numarray conversions). Changes to proj4 wrapper to make Basemap instances pickle-able. 20050814: version 0.6.1: Added hurrtracks.py example (plot hurricane tracks from shapefile). Now includes pyshapelib (extracted from Thuban source). 20050811: version 0.6: sf bug #1254163 (make sure lat/lon limits of projection are floats) wiki_example.py and plotclimdiv.py examples added. Added 'readshapefile' method for reading and plotting data from ESRI shapefiles (requires pyshapelib from Thuban). plotclimdiv.py is an example that illustrates this. 20050628: version 0.5.2: fixed bug in meridian labelling when lon > 360 or lon < -180. Now fully "pylab free" if 'ax' keyword is used in Basemap.__init__ or all of the Basemap methods that do drawing. 20050626: version 0.5.1: Added ability to specify an existing axis instance in all Basemap methods (instead of just using current one). Default is still to use current axis instance. Full control of font properties for parallel and meridian labels (now uses unicode instead of mathtext for degree symbol). 20050602: version 0.5 Added Orthographic, Mollweide and Robinson projections. Added 'drawmapboundary' method to draw a line around the map projection region. Added 'suppress_ticks' keyword to Basemap.__init__ It's True by default, but can be set to False if you want to label ticks in native map projection coordinates. Added 'rotate_vector' method to rotate vectors to map projection coordinates (without interpolation, as in 'transform_vector' method). Modified pcolor, contour, contourf methods to use masked arrays. Now requires matplotlib-0.81 drawparallels and drawmeridians methods now take optional keyword arguments 'xoffset' and 'yoffset', which control how far from the edge of the map labels are drawn. 20050511: version 0.4.3 Added Oblique Mercator. great circle calculations now use vincenty's equations for an ellipsoid. 20050510: version 0.4.2 transform_vector now does a simple rotation of the vector from geographic to map coordinates, preserving the vector magnitude (removed 'preserve_magnitude' keyword). Minor bugs in Miller and Mercator projections fixed. Added Gnomonic, Cassini-Soldner and Polyconic projections (now 13 projections supported). 20050509: version 0.4.1 Miller projection was erroneously referred to by the name 'miller' (instead of 'mill') - fixed. Added the ability to specify the major and minor sphere radii by specifying the 'rsphere' keyword in __init__ to be a tuple instead of a scalar. 20050505: version 0.4 added support for miller cylindrical, equidistant conic, and azimuthal equidistant projections. Bugs fixed in coastline drawing and continent filling methods. 20050427: version 0.3.3 fillcontinents modified to not fill lakes (they are actually still filled, but with axis background color). 20050420: version 0.3.2 - code cleanups and docstring typo fixes. env var BASEMAP_DATA_PATH can now be used to point to data files in a non-standard install (i.e using --prefix or --home). 20050415: version 0.3 Added transform_scalar and transform_vector methods for interpolating scalar and vector fields to a map projection grid. Added shiftgrid and addcyclic convenience functions. Added quiver_demo.py example illustrating how to plot wind vectors on a map. Updated examples to use transform_scalar instead of calling interp directly. Mercator x coordinate units changed from degrees to meters setup.py now installs data in python-version-numbered directory. (so you can have separate copies for different python versions). Fixed aspect ratio of mercator plots. Added set_axes_limits,plot,scatter,contourf,contour, pcolor and quiver methods. axes instance no longer a method argument (API change). 20050410: version 0.2.1 - add gcpoints and drawgreatcircles methods. Added intermediate resolution coastline and political boundary databases. Fixed bug in filling continents, and another bug in drawing parallels/meridians. Added 'ireland.py' example. 20050404: version 0.2 - drawparallels and drawmeridians can now draw labels at edge of map. 20050331: version 0.1.2 - now can handle negative longitudes (patch from Michael Brady). basemap.interp can now handle irregular (but still rectilinear) lat/lon grids. 20050203: version 0.1 released on SF. 20050202: Changed LineCollections.color to set_color in a try/except block. (color was a typo in 0.71 and is deprecated). 20050130: no user visible changes. Uses new pyrex generated C extension interface to proj.4 which is twice as fast as the Thuban one. 20050124: some code reorg, fixed bugs in S. Hem. projections. xmin,xmax,ymin,ymax Basemap instance variables renamed to llcrnrx,urcrnrx,llcrnry,urcrnry. Added __call__ and makegrid methods to Basemap class. 20050121: proj.4 is now called via a C-library interface, instead of using the proj command-line tool via os.popen. 20050119: fixed glitches in drawing of parallels and meridians.
