A GIS based Analysis for Rooftop Rain Water Harvesting
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2016, Vol 7, Issue 4
Abstract
For properly Digitizing the Roof area of any building, some parameters need to be determined in order to get maximum benefit. Google Earth is used to determine the view or the area with proper resolution. The resolution should not be too high to cover the building which have small area and should not be too low to cover large building. The QGIS tool is used to convert raster file into vector file for calculating the area. Then the amount of rainwater and the Tank capacity is calculated to collect the water. This paper concerns with computation of the required Roof area for collecting the Rainwater with a minimum or maximum average rainfall of the particular area and a Rooftop coefficient. The digitization has been done in QGIS for calculating area of different buildings with different parameters and a comparative analysis of collected Rainwater from Roofs and also provides the necessary parametric specifications to make Decision support system and to setup the Rooftop Rainwater Harvesting plant.
