Urbanization and human settlement data on the UN-HABITAT Open Data Portal

January 18, 2021 Leave a comment

The UN-HABITAT OPEN DATA portal, https://data.unhabitat.org/, is an interesting and useful way to obtain data on urbanization and human settlement.  UN-Habitat, the United Nations Human Settlements Programme, is mandated by the UN General Assembly to promote socially and environmentally sustainable towns and cities. It is the focal point for all urbanization and human settlement matters within the UN System. The creation of sustainable human settlements requires the provision and application of accurate, up to date, timely and reliable data.

The portal’s Compilation of Urban Indicators Data allows the user to explore by SDG Goals, by specific themes such as land and environment, quality of life, governance, and others.  You can also explore all data in the library.

Because the site uses ArcGIS Hub technology, the site is responsive, and you can easily search for data of interest. You can also search for type of document, such as web mapping application or dashboard. I used the site to search for land cover data and was pleased at the variety (scales, locations) and volume of results. At the time of this writing, 132 countries, 77 indicators, and 1500 urban areas are covered in the portal. The chief challenge with this and similar sites is to effectively narrow what you are seeking.

Research tying spatial data to resiliency and development goals

October 27, 2019 Leave a comment

One goal of this blog and our book is to raise awareness and action to develop data sets, data standards, and data portals so that decisions will be increasingly made with geospatial information.  One of the chief challenges to this is the persistent lack of geospatial information.  It isn’t just “us” as the GIS practitioners talking with each other about this.  As far back as 1992, Goodchild, Haining and others were pointing out this very thing in their article in the International Journal of GIS.

More recently, research studies have appeared that tie spatial data to much broader resiliency and development initiatives–specifically, that the lack of data is hindering some much broader planet-wide goals.   A white paper entitled Transforming Our World:  Geospatial Information: Key to Achieving the 2030 Agenda for Sustainable Development ties the need for geospatial data to meeting the UN Sustainable Development Goals.  In yet another example, both of the following studies indicate that the lack of data is one of the biggest obstacles to progress toward the UN development goals.

  • United Nations Independent Expert Advisory Group (UN). 2014. A World That Counts: Mobilising the Data Revolution for Sustainable Development. A Report to the UN Secretary General. New York, NY: United Nations, p. 28.
  • Stuart, E., E. Samman, W. Avis, and T. Berliner. 2015. The data revolution: finding the missing millions. ODI Research Report 03. London: Overseas Development Institute, p. 51.

The following study states that advances in research on resilience and vulnerability are hampered by access to reliable data.

  • Barrett, C. B. and D.D. Headey. 2014. Measuring resilience in a risky world: Why, where, how, and who? 2020 Conference Brief, 1. May 17-19, Addis Ababa, Ethiopia. Washington, D.C: International Food Policy Research Institute.

The biological and conservation community has been particularly active in this area, pointing out the unequal distribution of biodiversity data across the globe, by region, over time, and also in the coverage of certain taxa and ecosystems, such as in the following articles.

  • Amano, T., Sutherland, WJ.  2013.  Four barriers to the global understanding of biodiversity conservation: Wealth, language, geographical location, and security.  Proceedings of the Royal Society B  280.  (article 20122649)
  • Gaiji, S., Chavan, V., Ariño, AH., Otegui, J., Hobern, D., Sood, R., Robles, E.  2013.  Content assessment of the primary biodiversity data published through GBIF network: Status, challenges, and potentials.  Biodiversity Informatics 8(94):  172.
  • Osawa, T., Jinbo, U, Iwasaki, N.  2014.   Current status and future perspective on “Open Data” in biodiversity science, Japan.  Japanese Journal of Ecology 64:  153-162.

Global Imagery Donation From Planet Labs

October 5, 2015 1 comment

Planet Labs, an US based imaging company that operates a constellation of miniature satellites, recently announced a new collaborative project with the United Nations and a number of private institutions and NGOs. The initiative, known as Open Region, will see the publication of $60 million worth of global imagery under a Creative Commons License Attribution-ShareAlike (CC-BY-SA) license.

The data will be available online through the Planet Labs imaging platform and accessed using web-based tools and/or an API for developers. The hope is easy and open access to the new data sets will provide a platform to help meet the UN’s Sustainable Development Goals, which include tackling climate change, promoting sustainable use of resources and eliminating poverty.

Bhuvan Ganga (Ganges) Web Portal

July 21, 2015 Leave a comment

The Un-Spider Knowledge Portal (United Nations Platform for Space-based information for Disaster Management and Emergency Response) recently reported the launch of the Bhuvan Ganga web portal and the Bhuvan Ganga mobile application. This new monitoring initiative will use existing geospatial information and crowd-sourced reporting to monitor pollution levels in the River Ganga (Ganges). The data portal already provides access to a variety of geospatial information including as flood hazard zones and environmental data and visitors to the site will be able to contribute to the project by uploading shapefiles and WMS layers. The accompanying mobile app will also allow users to collect and report information on pollution sources affecting water quality in the River Ganga basin.

The host geospatial platform, Bhuvan, was one of the projects we discussed in The GIS Guide to Public Domain Data. Impressed by geospatial resources such as Google Earth but concerned about potential misuses of the information following the terrorist attacks in Mumbai in 2008, the Indian Government launched its own version, describing Bhuvan as a gateway to the geospatial world. The benefits of providing open access to national, regional and local geospatial information outweighed lingering concerns over potential future attacks. Over the last seven years the site has developed into a comprehensive resource of geospatial datasets and services.
