message: This file is purposely being maintaining in GIF format (along with a PNG-format version) for longitudinal studies of Wikipedia performance, of PNG versus GIF format.  Such studies are needed to avoid OR (original-research) claims of performance, but rather, show actual live examples in Wikipedia-image displays compared over a period of years.  This image is intended to co-exist as a GIF version of the equivalent PNG-format image for years (not days) to compare performance while evolving Wikimedia software is modified over those years. -Wikid77 05:42, 23 August 2007 (UTC)

message: There are multiple formats (GIF & PNG) for the county map:
::* GIF format:  :Image:Map Hudson County New Jersey municipalities.gif
::* PNG format:  :Image:Hudson County, New Jersey Municipalities.png.
The 2 versions are intended to co-exist for years, as the long-term performance of the evolving Wiki software is studied. -Wikid77 05:42, 23 August 2007 (UTC)

message: In August 2007, the GIF file stored as 22 kb, while the PNG stored as 20 kb (10 % less). However, when displayed as resized to 350px thumbnails, the GIF file displayed as 24kb while the PNG file resized for 350 px displayed as 65 kb (PNG about 2.7× slower than GIF), offering further evidence that such a map should NOT be re-converted into slower PNG format from GIF.
Even for a smaller thumbnail size of 130px, the GIF file was nearly 2.3× times faster/thinner than the PNG file (see properties/size tabs of the 2 displayed thumbnails at right), with the resized PNG image using 16614 bytes and GIF using 7108b:  ratio 16614 / 7108 = 2.337.
Studies from 2006 showed similar performance on Wikipedia and Wikimedia Commons: GIF files were typically displayed 2.7× (or 3×) times faster than PNG files at the same image width.  Images displayed on Wikimedia Commons showed the same performance difference (GIF nearly 3× faster than PNG), as though Wikipedia and Wikimedia Commons used the same image-display software, for resizing image files.  -Wikid77 05:58, 23 August 2007 (UTC)

message: Townships in New Jersey are "incorporated." This map [Hudson County] is misleading by using the label "incorporated place" to refer to the other types of municipalities. Unincorporated parts of counties are more common down South and out West; where there are places with no local government where the County itself administers services.

replies: text: 25-Aug-2007: I have verified that NJ townships have been incorporated for over 300 years (see: "Newark was incorporated as a township in 1693" in the 1911 Encyclopedia Britannica article, webpage: www.1911encyclopedia.org/Newark,_New_Jersey).  The label "incorporated place" could be changed to "City or Town" for this Hudson County map.  Thanks for the note, and I realize there are other Wiki "facts" at least 300 years out-of-date.  It's a challenge to get people to focus on long-term concerns.  -Wikid77 23:27, 25 August 2007 (UTC)
