[GRASSLIST:1374] Re: why the obtained area data was small than the real area?

[Alip.Yasin]

Dear GRASS Users
Dear Sir Hamish

Thank you for your help at all the times.

My obtained data (only one lake) through command r.report was still small
than real data.
Thank you to any of your advice.

  >> 1. make a UTM location and mapset
  >> 2. r.in.bin to import Landsat image.
  > >3. r.digit to make an area which surroundes my target area(only one
lake).
  > >4. r.report  and obtained area data 0.623 km^2 <<<< the real area
500~700 km^2.

>g.region rast=YourMap
>r.report will only report on the current region (display monitor). For
>the full map data you have to zoom to the extent of the map.
