The Liquid Resize map projection, however, is not only useless for most map applications - as the size, shape, and position of most countries are quite distorted - but its creation includes two steps which are outright counterproductive. (The next comic's projections Time Zones based on these, has #79 and could be concluded as being less bad than this one, which also seems realistic as this map looks more like a normal map projection, although it also has huge flaws). Quite possibly he does, since all 2D projections of the surface of a 3D sphere will be bad in certain respects. This comic suggests that there are many other projections than the 12 from the previous map projection comic, and Randall seems to have an entire list, of which at least 358 are "Bad Map Projections." The one presented here is #107 and is it called the "Liquid Resize." It is unclear if he includes the previous 12 in this list. Local maps of smaller areas can be quite accurate, but the idea of both these map projection comics is to map the entire globe on a flat surface. None of them are truly perfect as any 2D map projection will always distort in a way the spherical reality, and a map projection that is useful for one aspect (like navigation, geographical shapes and masses visualization, etc.) will not be so for all the others. Randall previously explored 12 different projections in 977: Map Projections, and expressed his disdain for some types he sees as less efficient but whose users feel superior. Each one will introduce a different type of distortion, and the best projection for a given situation is sometimes disputed. There is no perfect way to draw a map of the world on a flat piece of paper.
#GNU PATCHTOOL SERIES#
This turned into a series when 1799: Bad Map Projection: Time Zones (#79), was released just a bit more than a month after this one. This is the first comic in the series of Bad Map Projections presenting Bad map projection #107: The Liquid Resize. Enjoy.įYI, If you want to get deeper into DasBlog development and start including patches, you'll want to subscribe to the checkin mail for DasBlog's CVS so you'll know what's changing when.Title text: This map preserves the shapes of Tissot's indicatrices pretty well, as long as you draw them in before running the resize.
#GNU PATCHTOOL WINDOWS#
Now you can use CVS on Windows and play with CVS patches/diffs, making and patching with ease and grace.
#GNU PATCHTOOL PATCH#
patch to the same folder as the original. patch file and click "Open With" and associate it with your new patch.bat (not the patch.exe)
#GNU PATCHTOOL DOWNLOAD#
Download the GNU version of Patch.exe for Windows and put it in your path (or in your C:\Utils, if you're me).Open the patch file in Notepad2 and revel in the fact that Notepad2 already has the syntax highlighting setup to help you visualize the patch differences.Why? Because it's one better than Notepad. If you're me, and you want to apply a patch file: (or if you're not me and you just want to apply a standard DIFF/PATCH file on Windows without pulling your hair out) For example, if you're patching the patch should be .patch. The file's overlay indicator will change to tell you it's been edited. Note that with CVS you don't have to "reserve" a file for check out.
