Population Data
Egypt population census 2006 and 2017 were used to compute the
population growth for the four cities in the level of sub sections (Shiakha and
Village).

2.4. Data Processing
The following diagram shows the detailed steps of data processing work

2006 and 2017.

Image classification is the process of sorting pixels into finite number of
individual classes or categories of data, based on their pixel values. (B. Bhatta

maps; there are two types of classification: supervised and unsupervised.
