India- areas under irrigation The map “India – areas under irrigation” uses irrigation data from AQUASTAT, FAO's global information

system on water and agriculture, http://www.fao.org/nr/water/aquastat/main/index.stm.

The number of cells in the AQUASTAT data set is huge: 4320 columns x 1260 rows = 5,443,200 5 arc min

cells. To bring this down to size, I clipped the map to the area of India. Even so, I had more data (over

27,820 than ArcMap could process (max: 10,000 items) in computing equal percentage intervals (see the

map legend). Nonetheless, the resulting map corresponded well to the Global Map of Irrigated Areas,

http://www.fao.org/nr/water/aquastat/quickWMS/irrimap.htm. The Ganges River basin is the most

irrigated area in the world.

Map of projected projection for India in 2015 This map that shows projected population in India in 2015. The data comes from the Population Count

Grid, Future Estimates of the Gridded Population of the World, Version 3 (GPWv3). Future Estimates

consists of estimates of human population for the years 2005, 2010, and 2015 by 2.5 arc-minute grid

cells and associated data sets dated circa 2000. For more information, view the metadata.

As with my other maps, I created this map using Esri ArcMap 10. Each 2.5-min cell contains a value of

the estimated population for that area in 2015. I have overlayed the population layer on top of the

Ganges-Brahmaputra River Basin layer.

Unfortunately, I was not able to create a legend for this map. I have shared an ArcMap document

(.mxd), a PDF file, and JPEG image via Google Drive. By selecting the population layer in the .mxd file and

using the identification arrow, you can find out the population for that 2.5-min cell.
