Description
What it is for?
The Population To Grid (GHS-POP2G) is a flexible tool to produce geospatial population grids in GeoTIFF format from vector census data (polygons or points).
The tool operationalises the workflow developed for the production of the Global Human Settlement Layer Population Grid layers (GHS-POP).
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.
It is part of the GHS Layers which are extensively used in in crisis management, as they are key variable in disaster alert system. GHSL area used also for disaster response as population density, provide insights on the population in need of emergency relief. Increasingly GHS layers are used to projecting future climate change impact by combining population projections with that of hazard impacts.
Urban planners use GHS layers to understand the built-environment within a city, and regional planners use GHS layers to assess the impact of the expansion of cities on other land covers. The layers also inform policy makers that assess the degree of urbanization in the respective countries, or urbanization trends across countries or across regions of interest. The spatial arrangement of built up and green areas within a city is used to quantify climate impact, quality of life in cities based on the amount of green area or the access to transport facilities.
