What Once Was New

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.
Dec 10th, 2012 New page: the mathematical development of the Kavrayskiy VII projection.
Dec 5th, 2012 Fixed a typing mistake which prevented larger versions of the satellite general vertical perspective maps from showing.
Dec 3rd, 2012 Redrawn all images and equations for the development of the Aitoff, Hammer, and Winkel tripel projections, plus a few new maps.
Nov 26th, 2012 Redrawn all images and equations for the development of polar and equatorial azimuthal equidistant and equal-area projections.
Nov 21st, 2012 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 "how-to" 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, semi-automated 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.

Jun 28th, 2012 Redrawn star projections by Maurer.
Jun 18th, 2012 New and redrawn conoalactic maps.
Jun 14th, 2012 After a tip by E.Spinielli, fixed link which prevented images from showing in the dithered version of pseudoconic map projections. All URLs in my site containing "Dither" are obsolete and should be replaced by "Normal"; please update your bookmarks.

Fixed some typos; the worst, in the distance distortion page, was noticed by Carl Nordman - 100000 centimeters are not 1000 kilometers!
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.

Aug 3rd, 2009 Replaced maps for Waterman's projection. Added a comparison diagram for icosahedral maps.
Jul 27th, 2009 Another week, another projection: Fisher/Snyder's equal-area design for the icosahedron and other polyhedra.
Jul 20th, 2009 Added Fuller's Dymaxion™ map on an icosahedron. New angular deformation patterns.

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 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.

Dec 15th, 2008 Revised all images with Tissot's indicatrices, and added three new maps. Finally completed text revision - almost nothing remains of the previous version.
At the projections summary page, I had inadvertently left out copyright notices for images I received from Xarax, Waterman and Halstead - sorry.

Oct 7th, 2008 Replaced almost all maps in the premodern projections section with better or larger versions.
Sep 29th, 2008 In the map projections section, almost completely rewrote the geodesic page: all images improved or replaced.
Sep 17th, 2008 Fixed size error when opening larger maps in separate windows in some browsers.
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 25th, 2008 The map projection section now includes the general vertical perspective projection.
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:
  • replace all outline maps in my map projection pages
  • add a new feature: click on maps to get a larger version
  • remove the dithered version. It's unfortunate, but I must make up for the added disk space, and I guess very few people at present still need dithered images
These changes are already applied in the azimuthal projection section, and I intend to progressively update all other sections. That page was also split in two, since I expect to expand its contents.
Mar 22th, 2008 Trivial additions to the map projection pages, including a diagram comparing cylindrical projections. Also fixed or added some links.
Mar 3rd, 2008 Redraw figures and expand text for defining equal-area projections. Fixed characterization and moved Lee's map on a tetrahedron to the polyhedral maps section.

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.
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.

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.

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 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 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.
Jan 16th, 1997 Writing Netspace tools description.
Jan 10th, 1997 Installed preliminary pages in A-HAND site. New cartography page.
Dec 26th, 1996 After a long delay start writing my home page
