Para quem usa e/ou tem interesse em População et al.:

The POPGRID Data Collaborative brings together the major producers of
gridded population  and human settlement data, as well as key users and
stakeholders, to coordinate efforts and better respond to user needs.
POPGRID is pleased to announce the launch of a Web site
<https://www.popgrid.org/> that guides users on the products available and
their characteristics (including comparison tables
<https://www.popgrid.org/compare-data>), and a map tool (POPGRID Viewer
<http://sedac.ciesin.columbia.edu/mapping/popgrid/>) that enables visual
and quantitative comparisons among data sets.

POPGRID viewer provides a four-panel display of six different data sets:
CIESIN's Gridded Population of the World (GPWv4.10) 2015; ORNL's Landscan
2015; WorldPop's WorldPop 2014; JRC-CIESIN's Global Human Settlement
(GHS-Pop) 2015; ESRI's World Population Estimate (WPE) 2016; and
Facebook-CIESIN's High Resolution Settlement Layer (HRSL) 2015. A single-panel
mode <http://sedac.ciesin.columbia.edu/mapping/popgrid/comparison-view/>
provides
metadata on input data, and allows users to draw a polygon or upload a
shapefile to generate a table and chart with population totals for all six
data sets, providing side-by-side comparison of population estimates.

POPGRID is supported by the Bill and Melinda Gates Foundation
<https://www.gatesfoundation.org/> and underwritten by the NASA
Socioeconomic Data and Applications Center (SEDAC
<http://sedac.ciesin.columbia.edu/>) managed by CIESIN
<http://www.ciesin.columbia.edu/> at Columbia University. Major
participants are included on the Find Data
<https://www.popgrid.org/find-data> page.
