s. Here, as a value indicating
that the sites are preferred for location selection of warehouses, the “warehouse
density in the quarter” has been used to constitute the dependent variable. After
addresses of the warehouses have been transferred to the GIS program, warehouse
density per quarter in Istanbul has been calculated as “warehouse number/km2
”.
Then, the average of the densities is calculated. When the average is calculated, the
extreme values are extracted in order to exactly reflect the main mass. The average
density of warehouses is found as 18 warehouses per square kilometres. Places above
this threshold value are considered in the following sections of the study as regions
where warehouses are concentrated (preferred location for warehouses), and places
below are considered to be places where there is no warehouse density (not-preferred
location for warehouses).
