VALiN-POP: A New Population Grid for the Metropolitan Region of the Paraíba Valley and Northern Litoral, SP, Brazil

The VALiN-POP population grid was developed for the Metropolitan Region of Vale do Paraíba and Litoral Norte, São Paulo, using spatial databases and local knowledge to build new variables indicating human presence and occupation, known as symptomatic variables. For their construction, an adaptation was made using non-linear statistical regression methods from the Random Forest algorithm and dasymetry techniques for data from the 2010 Demographic Census. The result is a population grid of the distribution of the volume of people (population per cell) in GeoTIFF raster format, in the WGS 84 UTM zone 24S projection, float type 32 with a spatial resolution of [100 x 100] m, with an accuracy of 82% (R²).

The variables used, the procedures carried out and the results obtained are described in detail in Silva (2023).
