Isohyet Map



An isohyet map is a type of contour map that uses isohyet lines to portray equal points of precipitation in a given period. This map is great for showing the amount of rainfall in a given area on a two-dimensional surface. The isohyet map above was generated to show the daily rainfall status on May 5, 2012 for Malaysia Peninsula. The isohyets indicate the amount of rainfall from 0-900 millimeters for that date in the Malaysia Peninsula. The areas in white received no rainfall on that date while the areas in darker green received up to as much as 25 mm of rainfall. The area that received the most amount of rainfall at 50 mm is shown in the darkest green. Isohyet maps can be helpful in retrieving and maintaining accurate records of daily rainfall overtime.
