Development of GIS Toolbar to Estimate Reference Evapotranspiration and Net Irrigation Requirement on Raster Based Approach 111
Maza, Minotshing; Bandyopadhyay, Arnab; Bhadra, Aditi.
An ArcGIS toolbar was developed with the help of ArcObjects within ArcGIS environment to estimate evapotranspiration (ET) and net irrigation requirement (NIR) on raster based approach. The toolbar can estimate ET on a daily or monthly basis either with Hargreaves and Samani method or FAO56-PM method and calculate the corresponding NIR on a monthly basis. The toolbar was tested using normal monthly meteorological data (maximum temperature, minimum temperature, relative humidity, wind speed, solar radiation and rainfall) collected from 133 India Meteorological Department (IMD) stations covering 19 agro-ecological regions from 1971–2000. These point meteorological data were interpolated using ordinary kriging method and resampled at 1 km spatial resolution to...
