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, Nick1 vote
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..1 vote

Hello new world please??1 vote
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.1 vote
This is the 10th time that I try to type-in something in the search box, and the link to Columbia's home page opens up instead. 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!1 vote
I would like to create my own country specific grid based on the population esitmates that are given by census department. Would you be able to help me in this?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
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.
I must be doing something incorrectly.
Looking for Africa but also tried with Global map.
Using Google chrome, Windows 10, attempting to repair with Winzip, files always come back as broken and incomplete when decompressing.1 vote
This could be TOOL NO. 1 for "saving the planet".
- Share Maps on Facebook.
- Add yearly, monthly, weekly and daily World Sustainability Index. Nearly important as daily weather report.
- Map of rate of change (daily, weekly, monthly, yearly)
- Yearly award ceremony for positive rate of change and absolute level.
Is there any correlation between sustainability map, poverty, violence, happiness maps?1 vote
Hi. I downloaded the population density, V4 data. However, I have not been able to uncompress the files. I have tried in 2 different computers using different software. I do not know if I am doing something wrong1 vote
On the URL http://sedac.ciesin.columbia.edu/maps/gallery/search/10 I sought information about the United States, in connection with my present research. By page 7 I realized the maps are largely sorted alphabetically by geographical location. Since I aim to see what's available, it appears that I have to click "next" another five dozen times in order to possibly reach the maps for USA. Is there a shortcut?1 vote
Murray, there is a “browse by location” at the bottom of the left column on the map gallery page. You can choose the US from there and that will limit the gallery to three pages. You can also search for “United States” at the top of the same column. If there is a specific map or data set you are interested in let us know and we can tell you what we have available.

You have an RSS icon on your main page that links to http://ciesin.columbia.edu/rest/rss/sedacnews, but the page says "Sorry... Page Not Found".
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.
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.
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,
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:
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.1 vote
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?
