Esri Ocean GIS Forum Keynote Speaker Announced

Learn How GIS “Closes the Gap” Between MetOcean Science and Resilience

ksDr. Kathryn Sullivan will share her experiences as a former Astronaut, Undersecretary of Commerce for Oceans and Atmosphere, and National Oceanic and Atmospheric Administration (NOAA) administrator, in her Keynote Address at the 2017 Esri Ocean GIS Forum.

Currently a Lindbergh fellow in aerospace history at the National Air and Space Museum and a senior fellow at the Potomac Institute for Policy Studies, Sullivan is an authority on the growing role of science in education, weather, ocean economies, homeland security, and public safety. With the addition of MetOcean content to this year’s Forum, she is uniquely positioned to present a fascinating view of the future of GIS in ocean and atmospheric work.

Before her distinguished career at NOAA, Sullivan was a National Aeronautics and Space Administration (NASA) astronaut, flying three space shuttle missions between 1986 and 1992. During the first mission, on space shuttle Challenger, she performed the first spacewalk by an American woman. In 1990, on space shuttle Discovery, she and her crew deployed the Hubble Space Telescope. Sullivan’s last mission was in 1992 on space shuttle Atlantis, logging a total of 532 hours in space.

After leaving the NASA Space Program in 1993, she served as NOAA chief scientist, and in 1996, she became president and CEO of COSI in Columbus, Ohio, a hands-on center of science and industry serving nearly 900,000 people annually throughout Ohio and surrounding states. COSI also operates the largest outreach education program of any science museum in the United States.

In 2006, Sullivan was selected as the inaugural director of the Battelle Center for Mathematics and Science Education Policy at the John Glenn School of Public Affairs at Ohio State University. She returned to NOAA in 2011 as deputy administrator, chief scientist in 2012, and administrator in 2014.

Please join us at the Esri Ocean GIS Forum to learn how you can help “Close the Gap” between ocean and atmospheric science and a resilient community.

Geostatistics and GIS to Analyze the Spatial Distribution of the Diversity of Fruit Flies: The Effect of Forest Fragments in an Urban Area

Environmental Entomology, Published 23 September 2017

By A G Garcia, M R Araujo, K Uramoto, J M M Walder, and R A Zucchi

“Fruit flies are among the most damaging insect pests of commercial fruit in Brazil. It is important to understand the landscape elements that may favor these flies. In the present study, spatial data from surveys of species of Anastrepha Schiner (Diptera: Tephritidae) in an urban area with forest fragments were analyzed, using geostatistics and Geographic Information System (GIS) to map the diversity of insects and evaluate how the forest fragments drive the spatial patterns.

“The results indicated a high diversity of species associated with large fragments, and a trend toward lower diversity in the more urbanized area, as the fragment sizes decreased. We concluded that the diversity of Anastrepha species is directly and positively related to large and continuous forest fragments in urbanized areas, and that combining geostatistics and GIS is a promising method for use in insect-pest management and sampling involving fruit flies.”

Spatial autocorrelation analysis of tourist arrivals using municipal data: A Serbian example

Geographica Pannonica • Volume 21, Issue 2, June 2017

By Uglješa Stankov, Tanja Armenski, Michal Klauco, Vanja Pavluković, Marija Cimbaljević, and Nataša Drakulić-Kovačević

“Spatial autocorrelation methodologies can be used to reveal patterns and temporal changes of different spatial variables, including tourism arrivals. The research adopts a GIS-based approach to spatially analyse tourist arrivals in Serbia, using Global Moran’s I and Anselin’s Local Moran’s I statistics applied on the level of municipalities. To assess feasibility of this approach the article discusses spatial changes of tourist arrivals in order to identify potentially significant trends of interest for tourism development policy in Serbia.

“There is a significant spatial inequality in the distribution of tourism arrivals in Serbia that is not adequately addressed in tourism development plans. The results of global autocorrelation suggest the existence of low and decreasing spatial clustering for domestic tourist arrivals and high, relatively stable spatial clustering for international tourists. Local autocorrelation statistics revealed different of domestic and international tourism arrivals. In order to assess feasibility of this approach these results are discussed in their significance to tourism development policy in Serbia.”

High resolution global gridded data for use in population studies

Scientific Data, Published Online 31 January 2017

By Christopher T. Lloyd, Alessandro Sorichetta, and Andrew J. Tatem

“Recent years have seen substantial growth in openly available satellite and other geospatial data layers, which represent a range of metrics relevant to global human population mapping at fine spatial scales. The specifications of such data differ widely and therefore the harmonisation of data layers is a prerequisite to constructing detailed and contemporary spatial datasets which accurately describe population distributions. Such datasets are vital to measure impacts of population growth, monitor change, and plan interventions. To this end the WorldPop Project has produced an open access archive of 3 and 30 arc-second resolution gridded data.

An excerpt of selected WorldPop gridded datasets at 100 m resolution, in plan view and as pseudo 3d stacks.

“Four tiled raster datasets form the basis of the archive: (i) Viewfinder Panoramas topography clipped to Global ADMinistrative area (GADM) coastlines; (ii) a matching ISO 3166 country identification grid; (iii) country area; (iv) and slope layer. Further layers include transport networks, landcover, nightlights, precipitation, travel time to major cities, and waterways. Datasets and production methodology are here described. The archive can be downloaded both from the WorldPop Dataverse Repository and the WorldPop Project website.”

 

Spatial Analysis of Chinese Grain Production for Sustainable Land Management in Plain, Hill, and Mountain Counties

Sustainability 2017, 9(3), 348

By Jinlang Zou and Qun Wu

“In the context of China’s food security, spatially explicit information on grain production is an important asset to achieve the sustainable management of cultivated land. Previous studies have shown that spatial mismatches exist between grain production and water and cultivated land resources. In this paper, county-level data are used to investigate the degree of spatial (mis)match between grain output and the geographical distribution patterns of plain, hill, and mountain counties.

County-level dominant landform classification into plain counties, hill counties, or mountain counties based on the China County Statistical Yearbook.

“We estimate the difference in grain output between these different types of counties with a Spatial Autoregression Model. The results indicate that plain counties have the highest grain output, followed by hill counties and mountain counties subsequently. The reasons for the higher production in plain counties lie in the presence of more cultivated land, as well as a higher degree of irrigation and agricultural mechanization. The current pattern of Chinese total grain production follows the law of substituting labor with mechanization. Improving efficiency in the use of water resources and chemical fertilizer is both urgent and crucial. In this paper, we propose that the future roles for total grain production in relation to landforms should be: increased production and competitiveness in plain counties, a stabilization of capacity in hill counties, and a decrease in grain production in mountain counties.”
