Dec 24th, 2012  Included maps for Kavrayskiy V and VII projections.  
Dec 19th, 2012  Peter Stebel spotted a typo in the cartographical definitions page: one nautical mile corresponds to one minute of arc (') along the Equator, not one second (").  
Dec 17th, 2012  Redrawn images and equations for the development of the sinusoidal projection.

Redrawn images and equations for the azimuthal
orthographic projection. Finally decent diagrams. Removed main link to obsolete dithered pages (for compatibility, legacy internal links remain) 

Nov 12th, 2012  Redrawn all images in the how projections work and Braun's stereographic cylindrical pages; all equations now decently done. Six more "howto" pages remain to revise, redraw and typeset...  
Nov 5th, 2012 
At the interrupted sinusoidal section, I had failed to mention
the maps by Deetz and Adams. Included one, plus a few additions.
(Teaser only) Also, I noticed I have for a long time neglected the section on how projections work, mainly because it's so tedious integrating mathematics and HTML. Since after all these years easy MathML support still seems a promise, I've implemented a simpler, semiautomated typesetting approach and next week I'll begin rewriting and rediagramming those pages. 

Nov 1st, 2012  Accidentally, several of the "previous"/"next" buttons at the Map Projections section had wrong links. Thanks to S.Ansari for reporting the problem.

Jan 10th, 2011 
2010 definitely was not a good year for my site. I was unaware
that, for several weeks, a server mishap left my pages
unavailable. Then, for weeks more a permission issue prevented
me from updating them. After that, my daily job conspired to
keep me away from them. Let's only hope 2011 will be better.
After a suggestion by Prof.R.Ibáñez, some images were redone in the map definitions and azimuthal projections pages. Text revised in those pages and elsewhere.

Jul 13th, 2009  Broke apart the old polyhedral maps page, which was too big and unwieldy. New maps on a cuboctahedron, including Fuller's first Dymaxion™.  
Jul 6th, 2009 
Map projection pages: added another projection
by Kent Halstead. I'm still implementing some new projections. 

Jun 29th, 2009  Map projection pages: some simple revisions at the azimuthal section; Redrawn and enhanced all maps for the oblique projections section. Hopefully next time I'll include one or two longexpected new projections...  
Jun 22nd, 2009  After a long intermission, maybe I'll get some free time from work and resume updating my cartography pages. For now, like a tired jogger, I must restart slowly  just revise the maps for interrupted Mollweide maps.  
Mar 17th, 2009  This is not a proper announcement. Due to job pressures, I've been unable to update my site in the previous months. Furthermore, I'll be without Internet access for about two or three weeks. If you have requested something and haven't heard of me, please repeat your contact in three weeks; sorry for the inconvenience.

Sep 16th, 2008 
Interrupted
map projections page: quick text revision.
Also, fixed image links in dithered versions of pages updated in August and September; from now on, those pages are considered obsolete (please don't link to them or to any other "dither" pages) but for some time will display exactly like the normal versions. 

Sep 15th, 2008  No new projections yet, just improved maps and diagrams in first page of section about interrupted map projections  
Sep 2nd, 2008  Optimized size of images in recently updated sections for pseudocylindrical and azimuthal projections  
Sep 1st, 2008  Improved all diagrams and maps in the pseudocylindrical projections pages.

Aug 12th, 2008  My daily job does not currently leave me much free time but, after much
procrastination, I decided rewriting my mapping software from scratch;
at present it's far from complete, though quite usable.
From now on I plan to:

Feb 13th, 2007  Trivial updates to the introduction to cartography and origami pages.  
Nov 16th, 2006  Added or updated links in the cartography resources page. (sorry, I'm still dealing with delayed jobs and email)  
Nov 1st, 2006  For personal reasons, I've been out of reach for the last 30 or so days, and still won't be regularly online for some time. If you have tried to contact me, please have some patience, or try again in a few days. I'm sorry for the inconvenience.

I'll be absent for a while. If you write me, don't expect answers before April.  
March 3rd, 2005  Fixed missing links to images in the dithered versions of pseudocylindrical and conformal map projections pages. Actually I'm considering altogether dropping the dithered versions.  
February 25th, 2005  Add new conformal map projections by Lee, Adams and Xarax.  
February 16th, 2005  Add a few more pictures of assembled polyhedral

May 4th, 2004  Redraw some highresolution PDF files for cubic and icosahedral maps.  
April 28th, 2004  Another method for PDF conversion looks promising. If confirmed effective, I will redraw maps already published.  
April 27th, 2004  A longdelayed enhancement: polyhedral maps in higher
resolutions in PDF for printing. Started with some icosahedral
gnomonic maps.
PDF files are nearly universal and, when printed, can be easily adjusted to the paper's size. Unfortunately, the PDF generator I use is apparently using a lossy algorithm when importing the original art, therefore the printed resolution is lower than expected: maps are somewhat fuzzy, especially at sharp edges. At present I have no solution for this problem. 

February 19th, 2004  Slightly edited page for conic projections, including new map for Braun's stereographic conic.  
January 22nd, 2004  Fixed accidentally deleted equations for Braun's stereographic cylindrical projection; revised text and maps for azimuthal equidistant projection. Added link to Buckminster Fuller Institute.

Simple updates elsewhere. 

July 21st, 2003  Still rewriting the
conic projections
section, now added Lambert's conformal conic.
Trivial editions elsewhere. 

July 14th, 2003  Begin long due rewriting of page for
conic projections.
Also, trivial editions at the mapping concepts and projection summary pages. 

July 8th, 2003  Originally, foldouts for polyhedral
pseudoglobes had all gluing tabs dovetailed for a more precise
alignment; however, that made closing the last face rather
difficult. Redrawn all foldouts with a slightly different arrangement
leaving one face with no tabs, so it is much easier to paste.
Also, fixed a few missing features, especially in dodecahedral maps.
Other small fixes at the map projection section: more precise definitions, slight editions at the perspective cylindrical and premodern projections. 

June 25th, 2003  Revise and expand introduction to mapping concepts;
add a "Lagrange" map to discussion of conformal
maps. New illustration for interrupted maps.

November 25th, 2002  Almost completely rewrote the section on cylindrical map projections; some issues clarified, some inconsistencies fixed.  
November 13th, 2002  I'm quite busy, but added a new virtual origami model: K2 by Robert J. Lang.

July 1st, 2002  New Wagner IX and EckertGreifendorff projections. Slight revisions.  
June 24th, 2002  Small revisions at the map projection pages. New orthoapsidal projection.  
June 17th, 2002  Several slight clarifications at the map projection pages; fixed
link to MicroCAM.
Having serious email problems lately; added a new address.  
April 3rd, 2002  I'm back to the connected world, and more than a bit busy...  
March 7th, 2002  I'll be out of reach of the Internet for a few weeks. Expect no updates this month.  
February 14th, 2002  Slight revision and reorganization of the map projections pages. New pseudoglobes on a cuboctahedron.

October 15th, 2001  New pseudoglobe on a
truncated octahedron, suggested by a (more sophisticated) design
by Steve Waterman (also fixed this link in my resources
page). A few minor additions and revisions. 

October 1st, 2001  New tetrahedral pseudoglobes at the foldout
section. Split pages: pseudoconic projections, modified azimuthal projections and other projections. New Van der Grinten III and IV projections. Minor revisions, a few links fixed.

August 27th, 2001  Revising some text, links and directory permissions.  
August 21st, 2001  For the map projection pages: small revisions in text, new set of navigation buttons (top and bottom), added some image attributes, restored Greek characters as images in alternative pages (e.g. for Opera users).  
August 7th, 2001  Add descriptions to most links in the map projection sections; works at least on Netscape Navigator 6/Mozilla.  
August 6th, 2001  Redrawn most maps of the cartographical properties
section. New polyhedral
variant of the Collignon projection. Revised many
maps for faster loading. Text revised and captions added throughout the map projection pages, along with new experimental layout. Unfortunately, some style problems remain: presentation is almost passable in Netscape Navigator 4, acceptable in Internet Explorer 5 and Netscape Navigator 6/Mozilla. The new files require Unicode support in order to display Greek characters; it works in Netscape 4 (although disrupting styles), Netscape 6/Mozilla and Internet Explorer 5, but fails in Opera 5. 

July 31st, 2001  New minor fixes for the map projection sections  
July 30th, 2001  Several minor corrections and additions  
July 23rd, 2001  New projections: Aitoff and
Winkel
Tripel; formulas for Hammer,
Aitoff, Winkel Tripel and polar and equatorial aspects of
two
azimuthal projections. Small corrections elsewhere.

May 7th, 2001  A few additions to the polyhedral projections page, including a textured butterfly map.  
May 2nd, 2001  Add a VRML model of the FIT.  
Apr 25th, 2001  Temporarily hosting videos of Tom Hull's FIT model as an aid to paperfolders  
Apr 9th, 2001  Small additions; added maps presenting unequal scale  
Apr 6th, 2001  Again, many small fixes.  
Apr 5th, 2001  Many small additions and fixes for the map projection
pages. Update: dithered version fixed as well. 

Apr 2nd, 2001  Added armadillo projection and heavenly maps  
Mar 30th, 2001  New page on map projection applications  
Jan 29th, 2001  Minor fixes.  
Dec 1st, 2000  By mistake, the recent updates hadn't been applied to some of the dithered versions of the map projection pages.  
Nov 21st, 2000  Revised diagrams for distortion patterns  
Nov 13th, 2000  After a long pause, resumed updating the map projections
section. Revised diagrams and newlyscaled maps for the
stereographic and orthographic cylindrical projections. New telephone prefix. 

Feb 29th, 2000  Added Winkel I and II projections and respective formulas. Small fixes elsewhere.  
Feb 23rd, 2000  Fixed some broken links in the cartography section  
Nov 8th, 1999  Burned all .GIF files, fixed a few links  
Oct 13th, 1999  Finally revised the howprojectionswork page: now include actual derivation of formulae for a few projections  
Sep 22nd, 1999  Small fixes. New Lambert conic projection  
Sep 21st, 1999  New Braun conic stereographic projection  
Sep 15th, 1999  All HTML files checked; fixed old missing link in the polyhedral map section  
Sep 2nd, 1999  Checking HTML files: cleaning syntax and a few links  
Jun 14th, 1999  Small fixes and additions throughout map projection pages, including continuous and interrupted Boggs eumorphic maps. Beginning with Bonne projection. Enhanced map summary.  
Apr 5th, 1999  Some additions to the map projection pages. New Eckert V projection.  
Mar 15th, 1999  Small additions to the map projection pages. New or improved interrupted maps. Beginning new page on maps and origami. 

Feb 17th, 1999  Reorganized whole map projection section. Now most color
maps in two versions, dithered and undithered so the user can
choose loading speed vs. color loss. Next time you visit
please be sure to start here. Note:
from now onwards quick references in this page point to the
undithered (quicker load, perhaps false colors) version. Most maps redone with more detailed graticules and much more uniform color schemes. At last started a page on polyhedral maps. Cut and fold a worldinabox. 

Feb 12th, 1999  Fix another embarrassing mistake, equalarea cylindrical
and equidistant cylindrical previously mismatched in projection
summary. Much improved conventional and interrupted homolosine maps. 

Feb 11th, 1999  Fixed gross old typing error about van der Grinten's projection  comparing it with Hammer's instead of Werner's. Coming big changes in the map projection section.  
Feb 2nd, 1999  Sorry, small mistakes fixed  
Feb 1st, 1999  Many, many small fixes and additions throughout the map projection section. A lot of internal crossreferencing. Also, add star projections by Berghaus and Maurer and Briesemeister's oblique projection. Now most maps in WWWoptimized palette dithered format. Undithered images usually awfully colored in 8bpp displays, while dithered images have larger files and look cheap and ugly in better hardware. Sorry, that's a hard decision.  
Jan 25th, 1999  Several additions to the cartography section. Most projections dated. New diagrams and maps for azimuthal projections. Introducing Lambert's equalarea azimuthal maps. Some comments on a bad choice of projections. At last added new conical maps.  
Aug 27th, 1998  Minor corrections. New page for Tissot's indicatrix. New Mercator map.  
Aug 23rd, 1998  Revising layout of map projection pages; begin changing map colors (8bppfriendly); unfortunately, dithered files are much longer and look ugly in 16bpp.  
Apr 16th, 1998  Minor corrections, new double Werner and Mollweide maps.  
Apr 9th, 1998  Minor corrections  
Mar 2nd, 1998  New phone number, 55(19)2894685

Jan 5th, 1998  Revising projection pages. Beginning of links page.  
Dec 19th, 1997  Started pages for interrupted and conical projections.  
Dec 18th, 1997  Added a summary of map projections  
Dec 10th, 1997  Finally started revising the map projections page. First create new pages for basic definitions and map properties.  
Jan 19th, 1997  New pages on how map projections work, oblique projections, specialized projections.  
Jan 16th, 1997  Writing Netspace tools description.
