Population To Grid Tool User Guide

Description

The Population To Grid tool (GHS-POP2G) –version 2- is an information system developed in the framework of the Global Human Settlement Layer (GHSL) to produce geospatial raster grids of population counts at different spatial resolutions. The GHS-POP2G v2 is a flexible tool to produce geospatial population grids in GeoTIFF format from census data. The tool operationalises the workflow developed for the production of the Global Human Settlement Layer Population Grid layers (GHS-POP). The GHS-POP2G v2 tool allows the creation of population grids at 50 m, 100 m, 250 m, and 1 km spatial resolutions, handling census data stored as point or polygon vector data (in latter case requires additional covariate as input for dasymetric disaggregation). The principal purpose of the tool is the production of the population grid used as input for the Degree of Urbanisation Grid (GHS-DUG) also produced in the GHSL framework. However the potential uses of the tool and population grids go far beyond this main application. The tool is a capacity enhancement asset in the framework of the multi-stakeholder effort for the uptake of the Degree of Urbanisation, the people-based harmonised definition of cities and settlements recommended by the 51st Session of the United Nations Statistical Commission as the method to delineate cities and rural areas for international statistical comparison. The GHS-POP2G, as all GHSL tools, is issued with an end-user licence agreement, included in the download package.
