Esri Announces Winners of Storytelling with Maps Competition

Esri logoEsri heralded the winners of the Storytelling with Maps competition at the 2011 Esri International User Conference (Esri UC). Chih Cheng Chang, director of the application system division at RiChi in New Taipei City, Taiwan, won first place for Best Web Map. Dr. Thanos Doganis, director of R&D at Terra Ltd., with Terra Mapping The Globe Ltd. in Athens, Greece, won first place for Best Mobile App.

Chang’s web map shows natural resources data, including hydrology, water resources, geology, and soil, and introduces professional GIS-related information to a general audience. Terra’s free mobile app for the iPhone provides points of interest, including hospitals and pharmacies on duty, for numerous cities in Greece.  The winners were selected by a distinguished panel of judges comprised of Jean McKendry of the American Association of Geographers; Frank Biasi of National Geographic; and Allen Carroll, Deane Kensok, and Damien Demaj of Esri’s ArcGIS Online Team.

Jack Dangermond presented the awards to the winners at the Esri UC in San Diego, California, on Wednesday, July 13, 2011. The competition was created to show how maps can visually communicate meaningful and interesting information about the world, people, and places.

A Spatial Analysis of the Moderating Effects of Land Use on the Association between Alcohol Outlet Density and Violence in Urban Areas

Drug and Alcohol ReviewDrug and Alcohol Review, published online 05 July 2011

William Alex Pridemore and Tony H. Grubesic

“Aims: While there is substantial evidence of an association between alcohol outlet density and assault, it is unlikely this association is constant across the urban environment. This study tested the moderating influence of land use on the outlet–violence association.

“Design: Cross-sectional ecological study that controlled for spatial autocorrelation.

“Setting, Participants and Measurements: Police-recorded data on simple and aggravated assaults were obtained for all 302 block groups (mean population = 1038) in Cincinnati, Ohio, USA. Addresses of alcohol outlets for Cincinnati were obtained from the Ohio Division of Liquor Control, geocoded to the street level, and aggregated to census block groups. Data on eight categories of land use were obtained from the Cincinnati Area Geographic Information System, with location quotients computed for each block group.

“Findings: We found substantial evidence that the impact of total alcohol outlet density, bar density and carryout density on assault density was moderated by land use.

“Conclusions: By taking into account local characteristics, policy-makers can make more informed decisions when regulating the placement and density of alcohol licenses in urban areas. Similarly, more systematic knowledge of how the association between alcohol outlet density and assault varies across the urban landscape should reduce harm and promote responsible retailing. Nevertheless, ours is one of the first studies to address the moderating effect of land use and we encourage further research to test the stability and generalisability of our results.”

Spatial-temporal Analysis of Wooded Grassland Ecosystem for Management of Wildlife Habitats using Landsat Imageries

FiBREFiBRE SERIES: Findings in Built and Urban Environments, July 2011

Dorothea Deus and Richard Gloaguen

“The study reports on spatial and temporal variation analysis of wooded grassland ecosystem as a contribution to sustainable management, conservation and monitoring of wooded grasslands ecosystem in Tarangire national park in Tanzania through mapping and analyzing the changes for a period ranging from 1979 to 2009.

“Documentation of loss or gain of wooded grassland as wildlife habitat in both time and space is crucial for their conservation and sustainable management.

“In order to accomplish the research, two categories of data were acquired as satellite based and ground truth data. Next to that, images were subjected into image processing operations to acquire the desired results. A supervised maximum likelihood classication algorithm was employed to categorize the wooded grassland ecosystem cover classes which were mapped from the satellite imagery namely woodland, grassland/shrub land, and barren. A post-classification change detection approach was applied to identify differences between scenes.

Tarangire National Park land cover maps 1979–2009

Tarangire National Park land cover maps 1979–2009

“The results obtained show that in 1979, the woodland cover occupied 52.82% (1515km2), grassland/shrub land 40.24%
(1154km2) and bare land 6.94%(199km2) of the total national park area in 1979. Checking on a direct 30 year difference 1979–2009, it was observed that the extent of woodland cover over the park has decreased substantially by 1230km2 (42.88%) while the shrub land cover has increased by 477km2 (16.63%) and 753km2 (26.25%) respectively.”

How Can Theoretical Cartography Contribute to GIScience: A Philosophy Perspective

ICAProceedings of the 25th International Cartographic Conference, Paris, France, 03–08 July 2011

Q. Du

“Theory issue behind map and GIS has been always a tough and controversial theme which is critical for them to become sciences in multi-disciplinary circle. To build a theoretical framework for modern Cartography and GIS discipline from different approaches is certainly beneficial to the further development of the two disciplines. Cartography and GIS are relatively separate disciplines; however, they have inherent correlation. By looking back to the development of theoretical Cartography, we can borrow something for on-going GIS theory development effort.

“Philosophy has been evolving for hundred years. Among numerous schools of them it is noted that two main turns have generally taken place, i.e., Epistemological turn from Ontology (or Metaphysics) and Linguistic Turn from Epistemology (Robert Greene,1980, Richard Rorty,1967). The three phases of philosophy development reflect the focus shift from reality itself to its representation both in our mind and language.”
