  1. Issue downloading GRUMP Datasets

    I've tried to download multiple GRUMP datasets and i get an error stating: HTTP Status 500 - Unable to compile class for JSP:.

    Is the site having technical issues?

    Thanks, Jesse Rozelle FEMA

      • GPWv3 link points to an alpha site

        Hi it's me Sneha :) I was visiting the GPW collections page and found a bug on http://sedac.ciesin.columbia.edu/data/collection/gpw-v4, towards the end of the last para on "To see the previous version of GPW, visit the GPWv3 data collection". The link to GPWv3 points to an alpha.sedac.ciesin page.

        • Broken link notification

          Dear Sir/Madam,

          On your website I came across a link-referral to greenhouse.gov.au about climate change and global warming.
          However, this website has ceased to exist. As a result, the link you are referring to on your site is inactive: http://sedac.ciesin.org/entri/guides/national-response.html (at the bottom of this page)

          On EnergiePortal we have recently published a report on climate change: https://www.energieportal.nl/english/climate-change

          Hence, it would perhaps be beneficial to replace the current (inactive) link with the above link provided by EnergiePortal?
          This way, visitors will still be able to access important information regarding our environment.

          Thank you in advance for your time and consideration.

          • Provide a sample request for WPS Population Estimation

            I am trying to execute the WPS but I'm not sure if the format of the xml that I'm providing is correct. A sample request would help me and other users to use the plugin more efficiently.

            Thanks

            • Give step-by-step instructions on using your datasets

              There should be a guide on how to properly use the datasets ie how to open them, use the data in JSON format. I, as a new user, know not how to open .tiff files or how to get the data into a CSV or JSON format. Guidelines on this would be much appreciated. The dataset I have downloaded is the zip with population density for 2015 for e.g.
              Thanks!

              • Population estimator no longer working?

                Is the population estimator no longer supported? It's showing only zeros now ...

                  Thanks for letting us know. We are in the process of updating the PES client to a new version which we should have available within the next day or two. The new PES client will be much improved and exponentially faster. Sorry for any inconvenience this may have caused.

                  • I think that GDP layers do not have projection

                    Hello, in GDP layers' metadata it describes WGS84 as its projection. Despite that, after downloading these layers, I realized that the folder just contained the tiff documents. So I think you may not have realized these layers are not projected.

                    All the best,
                    Luis

                              • Use much higher resolution data avilable for Norway

                                The GPW4 maps (e.g. http://beta.sedac.ciesin.columbia.edu/data/set/gpw-v4-population-density-adjusted-to-2015-unwpp-country-totals) uses lower resolution data sets for some countries than necessary. Nor example, it only goes down to municipality level in Norway, while 250 m resolution for that country is available here:
                                https://www.ssb.no/natur-og-miljo/geodata
                                It is distributed as a set of shapes (https://www.ssb.no/natur-og-miljo/_attachment/101145?_ts=13d3e62d7d0), and corresponding densities (https://www.ssb.no/natur-og-miljo/_attachment/260833?_ts=153847c0a78). I'm sure similar data is available for most other European countries.

                                • comparison between GPWv3, GRUMP and worldpop

                                  I found large inconsistencies for population count in Tanzania between GPW 2010 and worldpop 2010 at the district level (2002 boundaries). It looks like GRUMP is more comparable, but it is difficult to compare as GRUMP is not available for 2010. Do you know the reason for the inconsistencies? and would you recommend GPW or GRUMP when calculating population at the district level? Finally, will GRUMP be available for later years in the near future?

                                  Best,
                                  Julie

                                  • Can I get annual PM2.5 data from 1998 to 2012?

                                    The Global Annual PM2.5 Grids from MODIS, MISR and SeaWiFS Aerosol Optical Depth (AOD) data sets represent a series of three-year running mean grids (1998-2012) of fine particulate matter. Can I get annual data from this dataset?

                                    • Values in gl_grumpv1_ntlbndid_ascii_30 don’t match between .dbf and .asc files

                                      I’m looking at the identifier grid file, and the values in the gluntlbnds.dbf file don't match the content of the data in gluntlbnds.asc. For example, when I inspect the 1x1 degree area surrounding the point where Poland, Germany, and the Czech Republic meet, I see the values 167, 52, and 51. In the .dbf file, these should be 137, 111, and 110 respectively.
