  1. Fix the data downloader for GMIS and HBASE

    The data viewer does not display either of these layers and there are errors when trying to download.

    • Can we download through curl or wget command

      I wanted to download all India states village outlines (http://sedac.ciesin.columbia.edu/data/set/india-india-village-level-geospatial-socio-econ-1991-2001/data-download) directly to our server. Is it possible using curl or wget command? If yes, can you share sample please. Thanks.

      • polygon shapefiles for GPWv4 National Identifier Grid

        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.

        • I need numerical time-series data from NASA world maps

          I plot the data of systemic indicators and by isolating the periods of regular proportional change I identify the periods of emergent system transformation.

            • Update old Lotus 1-2-3 spreadsheets to .csv files

              http://sedac.ciesin.columbia.edu/data/set/cddc-china-agricultural-stats-1949-1990

              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?

              Thanks
              Dan

              • numeric data for impervious surface areas

                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?

                        On Android (not in desktop mode), I can activate neither the poly nor radius icon.

Would it be possible to shift down the search box, so that the links to both CIESIN and Columbia pages do not interfere with searches? Thanks!

                                    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.

                                    • Inconsistency in total population

                                      Hi,

                                      I am using the gpw v3 density maps on Matlab and I do a spherical integration to compute the total population on the planet.
                                      For every map from 2000 to 2020, I find 24% more than the UN projects. But the gap between SEDAC and UN counts only accounts for 2 or 3% in 2000 so there is another problem.

                                      Is it because in cells with both land and sea, the density in the data is the terrestrial density ? It would explain why I get too much total population when integrating while considering that the density is applicable…

                                      • please help me..

                                        Downloaded data from the site below. I unzipped them and tried to display in QGIS 2.14. It shows only black and white with min=0 and max=0.

                                        http://sedac.ciesin.columbia.edu/data/set/gpw-v4-population-density-adjusted-to-2015-unwpp-country-totals/data-download

                                        I must be doing something incorrectly.

                                        Thanks,

                                        • Read the data in Matlab

                                          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');
                                          figure
                                          mapshow(pop, R);

                                          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!
