I have downloaded your Human Footprint Index, v2 maps for both Europe and Asia; there were no Istanbul and other European cities in Turkey in both continental maps. Could you add the European side, please?3 votes
I have noticed a major discrepancy in the population estimation service's 2020 figures in comparison to the figures for previous years. When a shape is selected which includes parts of southeastern Romania, the 2020 figure returns numbers 10-15 million higher than the 2015 figure; it's especially noticeable when selecting an area east of Bucharest that had barely 300,000 people in 2015 and 6 million people in 2020. Often when selecting smaller areas in this region, the service has issues processing and hangs for a long time.1 vote
Do you have a plan to provide the updated data (2017 to present)1 vote
Hello, I've downloaded the Global One-Eighth Degree Population Base Year and Projection Grids Based on the SSPs, v1.01 (2000 – 2100) datasets and the readme file indicates that the data values are in number of persons, but the netcdf shows the units as degrees? Please can you clarify what the data values in the netcdf files? Thank you.1 vote

I ran into a problem downloading "shapefile only" SF1 data for California and Texas as the file size is over 100% of the limit and it is not possible to de-select demographic data to get the size down. Could you relax the download limit for these two states or allow splitting into downloadable file sizes?1 vote
I am unsure about the formatting of the geographical coordinates, would it be possible to have this information? I believe the data is in UTM format, but when converting it to latitude and longitude in degrees, the geographical location does not correspond to the state to which it is supposed to refer to. Would it be possible to have additional documentation on how the data was constructed and the formatting?
Thank you so much1 vote
I found in the eastern Italy map of this section : https://sedac.ciesin.columbia.edu/data/set/lecz-urban-rural-population-land-area-estimates-v2/maps an indication of "Bologna" located in the city of Ferrara (Bologna is below).
The map is very nice, by the way.
Well its good we have annual data of AOD PM 2.5 but it is much more helpful if we have monthly data and seasonal data also. It gives us opportunity to have a close look of analysis1 vote
Strangely, several countries partially lack data, with an outcome that some of the largest cities in the world are missing: Guangzhou-Hong Kong conurbation 70 million people; Copenhagen (one third of Denmark's population); Brussels and most Flanders (50% of Belgium's population); Buenos Aires (one third of Argentina's population on #2 city in South America) etc.1 vote

Hi, Would you be able to describe for me how exactly you converted our current enumeration boundaries to a nation wide grid system. I understand that you created this grid for all the countries in the world i just dont understand how you converted our current enumeration area counts to be reflected in your current GPWv3 system.1 vote
Hi, I am trying to read the population density data in 2005 and 2015 in Matlab. I am using the following codes.
[pop, R] = geotiffread('gpw-v4-population-density_2005.tif');
The reference R looks normal, but the density matrix pop has huge negative numbers in each entry. I also tried to use Mathematica to read the file, and it also does not work. Could you provide us simple examples on how to access your tif file? Thanks!9 votes
