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:
