|Dec 24th, 2012||Included maps for Kavrayskiy V and VII projections.|

|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, semi-automated typesetting approach and next week I'll begin rewriting and rediagramming those pages.

|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.

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 long-expected 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.|

map projections page: quick text revision.

resolutions in PDF for printing. Started with some icosahedral
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.

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.

|Apr 6th, 2001||Again, many small fixes.|
|Apr 5th, 2001||Many small additions and fixes for the map projection
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 newly-scaled 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|

|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 world-in-a-box.
|Feb 12th, 1999||Fix another embarrassing mistake, equal-area cylindrical
and equidistant cylindrical previously mismatched in projection
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 cross-referencing. Also, add star projections by Berghaus and Maurer and Briesemeister's oblique projection. Now most maps in WWW-optimized palette dithered format. Undithered images usually awfully colored in 8-bpp 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 equal-area 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 lay-out of map projection pages; begin changing map colors (8bpp-friendly); 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)289-4685|
|Jan 11th, 1998||New map definitions|
|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.|
