How to we convert a 3d sphere into a 2d maps (orange peel) How is the map oriented, are there tools i can use to orient myself on the map (ex. Maps also help us to look at the world from different perspectives. In the description and explanation of spatial data geographers often use maps. Different kinds of spatial data and different types of spatial analysis demand different map types. Several different map types are typically used to solve spatial problems. Dot maps: reveal patterns of spatial concentration (clustering) or dispersion. Choropleth maps: a thematic map using colour (or shading) to indicate density of a particular phenomenon in a given area. Isopleth maps: a map using lines to connect locations of equal data value. Cartograms: a map on which statistical information is shown in the form of a diagram. A powerful tool for analyzing complex spatial problems, multiple layers.
