Contrast to spatial scale. A small-scale map cover large regions, such as world maps, continents or large nations. In other words, they show large areas of land on a small space. They are called small scale because the representative fraction is relatively small. Large-scale maps show smaller areas in more detail, such as county maps or town ...
The hex map has also been popular for role-playing game wilderness maps. They were used in the Dungeons & Dragons boxed sets of the 1980s and related TSR products. GDW also used a hex grid map in mapping space for their science-fiction RPG Traveller. A number of abstract games are played on a hex grid, such as Abalone; the six games of the GIPF ...
Before learning how to convert PDF images to SVG images it may be useful to learn how to extract images from PDF documents and create PNG, GIF, and JPG images. By using Adobe Reader many images in PDF documents can be right-clicked, copied, and then pasted into any image editor. A popular, free image editor good for beginners is IrfanView ...
Cartographic scale or map scale: a large-scale map covers a smaller area but embodies more detail, while a small-scale map covers a larger area with less detail. Operational scale: the spatial extent at which a particular phenomenon operates. E.g. orogeny operates at a much larger scale than the formation of a river pothole does.

GIF images allow for the creation of animations. PNG is a lossless, truecolor image format. It is good for all maps and particularly for maps with more than 256 colours.
The term map composition is also used for the assembling of features and symbols within the map image itself, which can cause some confusion; these two processes share a few common design principles but are distinct procedures in practice. Similar principles of layout design apply to maps produced in a variety of media, from large format wall ...

A or x-scale; dimension of a pixel in map units in x-direction B, D are rotation terms C, F are translation terms: x, y map coordinates of the center of the upper-left pixel E is negative of y-scale: dimension of a pixel in map units in y-direction. The y-scale (E) is negative because the origins of an image and the UTM coordinate system are ...
