Plot Sizes and Distances
This post contains calculated areas for all plots and a method for calculating the true latitudinal distances in your plot. Plot Sizes About the projection and latitudinal distances This is a map with an equirectangular projection. It means that the further north or south from the equator, the more horizontal "stretching out" of the map there will be. As an effect, plots appear larger than they are due being projected wider. Vertically there is no "stretching out". For more information about the projection and resulting local distortion, see this Wikipedia article. The distance bar on the regional map is only accurate for the equator. If you want to measure distances elsewhere on the map, you have to compensate for the latitudinal distortion. Below is a table containing the so-called relative scale factor, k. To calculate the horizontal (i.e. latitudinal) distance at a given latitude, divide the distance measured with the distance bar by the scale factor. The formula below can also be used to obtain values between those provided in the table. The scale factor also tells you how much you need to shrink your plot horizontally to get a more accurate local representation. It useful for making your own customized maps for your plots or calculating distances between cities in your plot. Click here for an illustration. If for example your plot is mostly located at 35°S, k=1.221, meaning your plot is represented as 1.221 times wider horizontally than it really is, you scale the plot horizontally so that it is about 40.2% less wide. Distance calculation between two points on the map This link will take you to an online tool that helps you calculate the distance between two points on the map. |
