As a general rule, everything along the centre of the map (where the equator would be on a normal Equirectangular Projection) is free from distortion. This centres the map on an oblique line beginning at 45ºN 0✮, circling round to 45ºS. Using the latitude and longitude controls, you can specify precisely where the map is centred. Experiment and see what each projection looks like.įor building the base map, the projection we're interested in is Equirectangular Oblique. G.Projector's list of projections is quite extensive. You can now reproject the map in any way you like. In that case, the default settings of 90ºN, 90ºS, 180ºW, 180✮ are perfect. G.Projector is a bit limited when it comes to loading maps other than Equirectangular full world maps, so my advice is to always work with full world maps. After you point it at your world map file, it then asks what coordinates the edges of the map show. By default, it expects this map to be in the Equirectangular Projection. When you start G.Projector, it immediately asks you for a map. Used this as a guide to update the previous base map. As you can see, it's a little messy, so we I entered latitude -45º to reverse the change we made before, To Equirectangular Oblique, at which point it displays correctly. When loaded, the mapĪppeared very strange at first. The preferences to accept our map as Equirectangular Oblique,Ĭentred on 5✮, standard parallel 45ºN. Step was to load it up in G.Projector again, which meant changing I took the map into Photoshop and pasted in the circular GreatĬaldera. Note that the wholeĬentral area of the map is essentially distortion free, so the longitude The east, so we also changed the map to 5✮. 45ºN is about right, but the Caldera is slightly offset to Next, I changed the projection to Equirectangular The first step for fixing it was to load the map into G.Projector withĭefault settings. Even though it lookedįine on the Equirectangular map, this is how it would have looked on How distorted the Great Caldera actually was. Here's a Stereographic Projection of the same map. Not produce a perfect circle as it appeared to be. However, placing theĬircular Great Caldera as is on this Equirectangular map did The geographical isolation that it needed. It's a complete rethink of the map, giving the Great Caldera ![]() This is the fourth draft of Calidar, designed by Bruce Heard. Vector formats include SVG, DXG, AI, and many others. Illustrator works primarily with vector graphics. ![]() Fonts are probably the most common vector graphics encountered in daily life. Because they are defined using lines and points, it's possible to resize them freely without losing sharpness. They don't use pixels at all, although they can be rasterised – i.e. Vector graphics, in contrast, are made up of mathematical descriptions of lines and points. At this stage, Bruce realised that theĭesign had wandered away from the central concept of the Great Calderaīeing a safe haven, isolated from the Dread Lands around about, and we Note how we worked in a range of colour schemes Īt this stage in the design, working with whatever's easiest for you is fine.Īlthough these drafts were all ultimately rejected, you can see elements This means that you need to consider what resolution to work in from the start, because you won't be able to increase it later on. Raster images can often be shrunk down without incurring great problems, but enlarging them causes them to become blocky and/or blurry, and is best avoided. Photoshop and most other paint programs mostly work with raster images. Most people are familiar with these images from photographs, paint programs, and indeed the Internet. Raster graphics, also known as bitmaps, are comprised of arrays of tiny dots known as pixels. ![]() It's worth noting here briefly the differences between raster and vector art. I went back to the first draft and tried to split things up to I took a stab at the third draft, tracing Bruce's outlines to Illustrator The reason for this is that at this stage, only the general shapes are important small details on the coasts can be added later, so there's no need to worry about things looking too regular.
