The key value for a map is always unique and is used to access the specific pair in the map. A graphic scale solves the shrink/zoom problem because it is simply a line marked with the distance on the ground that the map reader can use along with a ruler to determine scale on the map.In the United States, a graphic scale often includes both metric and U.S. common units. The scale of a map shows how much you would have to enlarge your map to get the actual size of the piece of land you are looking at. Select which conversion approach you wish to use: a. b. Solution: Use ‘toInt’ If you need to convert a String to an Int in Scala, just use the toInt method, which is available on String objects, like this:. Please take a look why I defined schema which describes data from file. Converting Lexical Scale "1 inch represents 3.9 miles" to Representative Fraction (RF) and Ratio: First, I write the lexical scale as a fraction - 1 inch (on the map) / 3.9 miles (on the ground), then I convert the length unit mile to inches because the RF shows how many inches on the ground are represented by 1 inch on a map. The methods above to convert a measurement assume the scale factor is in the form of 1:n or 1/n, which means some additional work is needed if the ratio is 2:3, for example. Graphic Scale . This is an online scale length converter that calculates the actual length and the scale length according to the scale ratio. More about Converting Map Scales. For example, your map has a scale of 1:25 000, which means that every 1cm on the map represents 25 000 of those same units of measurement on the ground (for example, 25 000cm = 250 metres). Hello, I would like to determine how to a convert specific map scale to the closest zoom scale used by the major web mapping players. An engineering scale, expressing scale as an inch on the map being equal to a number of feet or meters on the ground, must be converted to a proportional scale when the CAD data is to be used in ArcMap.
