                  Population Computing
                      Based on the Egypt Census data of the years 2006 and 2017 on the level
                  of  household,  the  population  was  aggregated  on  different  administrative
                  boundaries levels, in the study I used the aggregated population on level of
                  Shiakha (city) which are the same boundary for the output classified images.

                  3.  Indicator  estimation  (ratio  of  Land  consumption  rate  to  population
                      Growth rate)

                  Population growth rate
                      The  rate  of  population  growth  can  be  calculated  using  the  following
                  formula:
                  Population Growth rate (PGR)=LN(Popt_(t+n)/ Popt_t )/((y))
                  Where
                      Popt Total population within the city in the past/initial year
                      Popt+n Total population within the city in the current/final year
                      y The number of years between the two measurement periods

                  Land Consumption Rate
                      The rate of land consumption was calculated from the resulting classified
                  images according to the Following formula:
                  Land consumption rate LCR=LN(Urb_(t+n)/Urb_t )/((y))
                  Where
                      Urb_t Total areal extenoft of the urban in km2 for past/initial year
                      Urb_(t+n) Total areal extent of the urban in km2 for current year
                      y The number of years between the two measurement periods

                  Indicator estimation (ratio of Land consumption rate to population Growth
                  rate)
                      LCRPGR = Land consumption rate / population Growth rate

                  Results
                      After  the  image  classification  process,  and  population  calculations  for
                  years  2006  and  2017.  the  following  table  shows  the  areas  and  population
                  belonging to the cities in the case study for each year:
                           Zakazek City       Cairo City     New Cairo City    Menia City
