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
maps.
A few days ago I received an e-mail from Alex Lidman, but something is blocking my attempts to answer it. If you read this, Mr. Lidman, please excuse me. | |
| February 9th, 2005 | New conformal projections by Peirce, August and Adams. Simple additions elsewhere. | |
| January 27th, 2005 | Beginnings of a new page on conformal projections. New Spilhaus map. Several fixes elsewhere. | |
| December 27th, 2004 | New tetrahedral maps. Trivial fixes elsewhere. | |
| October 13th, 2004 | Small clarifications at the map definitions page. | |
| September 13th, 2004 | Slightly improved text for
map
definitions,
map
properties and
premodern
projections.
Fixed PDF maps, previously inaccessible from dithered version of polyhedral projections page. |
|
| July 5th, 2004 | Purely cosmetic changes.
Corrected mistaken coordinate origin in description of UTM system, pointed by Dick Jarrell. |
|
| June 30th, 2004 | Small fixes at the page for pseudocylindrical projections. | |
| June 24th, 2004 | New polyhedral maps on a truncated octahedron. | |

| May 4th, 2004 | Redraw some high-resolution 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 long-delayed 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. |
|

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. |

| 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

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 lay-out. 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 30th, 2001 | Several minor corrections and additions | |

| 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

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
summary. Much improved conventional and interrupted homolosine maps. |
|

| 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. | |

| 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. | |
