  1. Open-sourcing your grid-making algorithm

    I'm from the Census Bureau and I am always being asked for a way by which people who wish to analyze our data either across different geographic boundary definitions or over time wherein boundaries changed. It would be so awesome if you guys could open-source your algorithm so that we could share it with the world of folks who need something like this :)

    • Hong Kong Urban Extent (GRUMP)

      The map for the Hong Kong Urban Extent (GRUMP v1) is incorrect - it shows NO urban extent, and Hong Kong is very urban...

        • Is there any way to download maps in a georreferenced .tif file? Thanks.

          The closest way i figured is to download the ascii file and import it as a raster, but it has no spatial reference.

          Thank you beforehand

          • make downloads resumable

            Very large data-sets (e.g., global roads at ~200MB) are very difficult to download at one go when in poor/unreliable bandwidth areas. Suggest one or more of the following:
            1. breakup data sets into smaller regional and/or country level chunks
            2. allow downloads to resume after interruption
            3. use distributed methods of serving data (p2p, torrents, etc) ... this will also reduce your server / bandwidth requirements!

            • information about data encoding

              Hello,

              I downloaded "Gridded Population of the World, Version 3 (GPWv3): Centroids". It is really terrific data! Bravo!

              But I must say that I wasn't able to use correctly administrative level names: problems with diacritic symbols (like "ñ", "ç", "à" etc.).

              I couldn't identify encoding of data (unicode, ISO8859-1, ?). So please could you give information about this encoding (inside metadata?).

              Thanks in advance.
              Michel (France)

                • improving the color chart of the Hazard map

                  RE : http://sedac.ciesin.org/maps/client

                  Hello,

                  The blue background is confusing, because I associate blue with the color of sea.

                  It is particularly true of the world map of Flood Hazards, I can not associate easily the colors on the maps, and the colors in the legend.

                  Yours sincerely,

                    • Increase the number in your display drop down to "All."

                      By having to download multiple files, 50 records at a time, it increases the chance for error. But also means I need to spend lots of time making sure I got everything.

                      • Provide working minimalistic openlayers WMS example

                        If you want to use SEDAC WMS with openlayers.js, it would be nice to provide a (link to a ) working sample code like http://jsfiddle.net/F9pUs/ (which actually does not show the SEDAC layer)

                        • Update the list of small-area estimate studies.

                          This isn't really feedback, but I didn't see another way to contact you about updating the list of small-area estimate studies. I worked with colleagues on a poverty map of the Lao PDR that is not included in the list. Here is the link: http://www.laoatlas.net/links/PDF/The%20Geography%20of%20Poverty%20and%20Inequality%20in%20the%20Lao%20PDR.pdf. Thanks, Nick

                          • not load the OpenLayers map on the homepage by default

                            perhaps this can be a snapshot image before trying to load the client everytime someone visits the home page. Click on the snapshot would enable the client or something like that..

                              Besides theme, year published, and year of data, can we have geographical coverage? Some users may be looking for data in specific areas, so it would be nice to have that upfront.

                              • Fiji Population Density GRID

                                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.

                                • Map client – needs to point back to the source of the data

                                  Map client – needs to point back to the source of the data – e.g. through link that show where the basic data is coming from, or through citation information in legend or label. This would enable readers to get reference documentation as well as getting the source datasets. Also would be useful to be able to print out the map and map metadata.

                                  • List data in one column instead of two

                                    The browse and faceted search performs great. My only thought is that it would be better to have the data listed in one column instead of two. Browse could be smaller on this page – then larger once you select your method of access (i.e., Website, download, maps, more….
