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

Your metadata used to be accessible by https. Did your certificate expire?
Here is an example error:

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.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
Hello, I'm hoping to be able to download the raster for the polygon shapefiles for the GPWv4 National Identifier Grid. The page says, "Rasters of all resolutions were also converted to polygon shapefiles." Thanks.1 vote

This dataset is in Lotus 1-2-3 format which is unreadable with modern software. Please could you update this to a future-proof CSV format?
I was looking at: -- Global Man-made Impervious Surface (GMIS) Dataset From Landsat, v1 (2010) -- But could find no table of numeric values. I was actually looking for time series of numeric values as a proxy for global habitat loss.
I'll look for the "footprint data" and "Nighttime Lights data", but suspect there may be no tables of numeric data for those too. I don't have the expertise to extract it. If I wanted to get time series for the global totals for these how would I get it?1 vote
- Don't see your idea?
