Infrastructural projects at regional scale are ones of the important components of modern digital economy. In relation to the forestry, the main objects that determine infrastructural load of the territory in the forestry are the networks of fire stations and forest roads with settlements and public roads. A method to define a cell size of a regular uniform rectangular grid based on the pixel size of MODIS-based vegetation raster is described. It is based on the statistics of number of settlements, fire stations and road sections, as well as road sections lengths. Exploratory regression was used to choose a cell size with a number of forest fires as a dependent variable and number of settlements, road segments and fires stations as independent variables. It was found that the most optimal size of regular grid cell for Krasnoyark Region (Kray) is 24 km². Paper’s findings could be used in climate and economic projects to estimate infrastructural load.

Key words: regular network, cell, infrastructural load, settlements, road network, GIS, forestry
