2 ArcNews Vol.34, nº4 Winter 2012/2013 U Spatial: A Consortium for the Spatial University Francis Harvey, Len Kne, Steven Manson 1 7 It is increasingly apparent to many within academia and beyond that spatial thinking, technologies, systems, and services matter. Building on a rich history of research, scholarship, and teaching related to spatial topics, the University of Minnesota (UMN) has embarked on a visionary endeavor called U Spatial to develop a collaborative consortium that supports the spatial sciences and creative activities. Transforming ArcGIS into a Platform Jack Dangermond 1 9 At the foundation of Esri s work are the belief and vision that geography is a science that creates a better understanding of our world. Using GIS, geography has also become a unifying framework for integrating many forms of digital information. GIS has now become an important technology in almost every field, improving efficiency, communication, and decision making. Esri s Geoloqi Acquisition 1 3 Amber Case Papeles de economía española. Nº What could your mobile application do if it knew where it was? Persistent location awareness has been the Holy Grail of location based services (LBS), particularly now that GPS has become a standard feature on today s mobile phones. Yet, until now, battery life has been a common issue that has prevented a satisfactory user experience. Geoloqi has created a patent pending technology that cracks that nut by getting clever about how to manage the native location tracking capabilities on a smartphone and optimize those services to give the application an awareness of when its user is near a relevant point of interest. Esri Host WWW Conference Reinventing the Art of Conversation What happens when some of the world s brightest minds come together in one location to talk one on one about anything and everything? No script. No preparation. No podium or teleprompters. It s more than an interesting premise or an esoteric exercise of what if. This past fall, it was a reality. The result was open, honest conversation about topics ranging from climate change to video games, insects, the inner city, and even the end of the world as we know it.
3 ArcNews Vol.34, nº4 Winter 2012/2013 GIS HERO Gref Babinski: Tireless Advocate for Expanding GIS Use in Local Government In 1971, when there were few employment opportunities for geography students beyond the classroom, Greg Babinski graduated from Wayne State University in Detroit, Michigan, with a bachelor s degree in geography. One of his teachers was William Bunge, who contributed to the understanding and application of quantitative geography. This research was later further developed with the expanded use of GIS technology. Influenced by the social unrest of the 1960s, Bunge became a political radical, says Babinski, but he had great insight into the power of spatial analysis for social justice.

GIS FOR BETTER CITY PARKS Alexandria, Virginia, Gets Serious About Park and Play Space Improvements Robby Layton 16 2 The United States is experiencing an obesity epidemic. People in Alexandria, Virginia, have decided to do something about it. A 2007 study determined that more than 43 percent of children in the city between the ages of two and five were overweight or obese. Recognizing that getting children active through healthy play is one way to address the problem, several local organizations partnered to obtain a grant from the Kaiser Permanente Healthy Eating Active Living (HEAL) program to conduct a study and improve access to public and semipublic play spaces throughout the city. ArcGIS is used to map the locations of play spaces and analyze play throughout the city. GIS allows planners to decide where play spaces should be improved or added.
4 ArcNews Vol.34, nº4 Winter 2012/2013 Website Helps Discover, Explore, and Improve US City Parks Breece Robertson, Bob Heuer The 40 largest cities in the United States each have their own character and personality. But one thing that they all have in common is the need for a great park system. Some cities are well on their way to achieving this goal, but others have a great deal of work to do. Parks are important to communities because nearby opportunities to exercise and experience nature are essential for physical and mental well being. Studies show that parks can encourage physical activity, revitalize local economies, and help bring neighborhoods together. GIS can be a valuable tool for improving park access. Built with ArcGIS, ParkScore is a free tool that empowers both individuals and city leaders to improve park systems. Assessing Accessibility to San Antonio Neighborhood Parks Shubhangi Jangam, Azza Kamal The significance of parks and recreational facilities was recognized and linked to social life and health in the past century. Since then, cities began to preserve land for parks and recreation. The city of San Antonio is being investigated in this study for its offering of adequate neighborhood parks. ArcGIS helps identify neighborhoods lacking easy access to parks. Inequality of access to parks among children 0 to 15 years old is revealed by GIS. GIS proximity analysis is a strong tool for cities and counties to leverage park accessibility policies. Papeles de economía española. Nº Model a New Neighborhood Park in Los Angeles, California The new edition of Understanding GIS: An ArcGIS Project Workbook (for ArcGIS 10.1) takes a fresh approach to teaching the essentials of ArcGIS for Desktop.

GIS IN AFRICA GIS help fight World s leading cause of preventable blindness It feels like thorns scraping your eyes each time you blink. Repeated infections during your childhood lead to scarring of the conjunctiva, or inner mucous membrane of the upper eyelid. Your eyelashes turn inward and scratch the cornea. Slowly, painfully, you may go totally blind. The affliction is called trachoma, and it affects mostly women and children among the poorest of the poor, especially in regions that have limited access to sanitation and water. Esri spatial technology is helping international efforts to eliminate blinding trachoma by 2020.Smartphone data transferred to ArcGIS servers and maps reveal hidden prevalence of trachoma.
5 ArcNews Vol.34, nº4 Winter 2012/2013 Improving service delivery and collaboration in South Africa 22 Named for one of South Africa s 20th century democracy advocates, the Frances Baard Municipality District is situated in a mostly rural area of the country s orthern central region. A sunny and semiarid climate and natural rivers make it a popular tourist destination for bird watchers, hunters, and photographers. The region is well known for its agriculture, with exports of fruit and vegetables, as well as mining activities. Using ArcGIS for Server, the Corporate GIS unit has made its data available to all local municipalities through a web portal. The Frances Baard Municipality District fixed spatial errors by re creating the parcels in ArcGIS based on the coordinates provided in source documents. GIS has facilitated more accurate utility billing, which in turn has created a better revenue stream for the district. Creating a National Park from the bottom up 23 Three rivers surround 40,000 square kilometers of mysterious forest in the heart of the Democratic Republic of Congo (DR Congo).

GIS IN ACTION GIS and ancient trees reveal past temperatures and climate change Walking among living trees that have stood on the side of a mountain since the times of Christ and Buddha is a humbling experience. In the White Mountains of California, ancient bristlecone pines grow to about two miles above sea level; above that, the weather is too harsh for trees to thrive or to even survive. Many of these trees are more than 3,000 years old and have made a living in an intensely harsh climate that is very dry, very cold, and very windy. The slopes are rocky and steep. The topography is complex.gis helps determine the varying climate conditions individual trees experience in complex mountain environments. Using mountainside temperature data, ArcGIS Spatial Analyst spotlights summer variations of several degrees for individual trees. ArcGIS shows that over centuries, positions of trees have fluctuated up and down the mountain slope as temperatures changed.
6 ArcNews Vol.34, nº4 Winter 2012/2013 Small town upgrades storm water management 28 The hydrology of landscapes surrounding urban areas is constantly changing due to the expansion of urban boundaries. As such, established and newly developing areas must implement cost effective means for restoring or minimizing the impact of change while planning for future growth. Among the many issues that can arise from increased urbanization, storm water management can pose significant challenges, particularly for municipalities located on floodplains. With GIS, officials view multiple georeferenced surveys at once and get a complete snapshot of the event. ArcGIS 3D Analyst and terrain dataset helped develop an accurate 3D representation of the town s surface terrain. Calculations are automated within the GIS, minimizing data preparation and maximizing time spent assessing floodrelated issues. Tracking vessels supports EU sustainable fishing policy 29 The European Union (EU) requires that fisheries be sustainable and not jeopardize fish stocks for future generations. Even so, Europe s fish populations continue to decline. Therefore, the EU Commission Reform of the Common Fisheries Policy (CFP) has been assessing the way EU fisheries are managed and the challenges they face. The Papeles commission de economía concluded española. that the main Nº131. contributor 2012 to overfishing is that the fleet s fishing capacity is greater than its fishing opportunities. The Republic of Croatia is monitoring its fishing fleet along the shoreline of the Adriatic Sea by using ArcGIS to track and monitor vessels. GIS will help the country meet the European Union s stringent fisheries policy. VMS is an open system compatible and easy to integrate with existing GIS environment and informational systems. A new probe for CSI? Bone researcher David C. Rose straddles two worlds. The Ohio State University (OSU) doctoral student in anthropology is also a captain in the University Police Division, a unique vantage point in which he sometimes deals with forensic investigations involving human remains. That exposure and his focus on skeletal biology prompted Rose to launch a project to determine if patterns of change inside human bones might reveal how they were used during life. ArcGIS software is used for the first time to map and analyze human bone microstructure. Mapping reveals spatial relationship of microscopic structures and how bone was used during life. University researchers prove that ArcGIS offers uses in forensic medicine, skeletal biology, and anthropology.

15 ArcNews Vol.35, nº1 Spring 2013 Participatory GIS 22 Sara O.I. Ramírez Gómez, Christian Martínez The nation of Suriname is tucked up against the Atlantic Ocean in northeastern South America. Southern Suriname is covered with continuous tracts of unspoiled tropical forest, and it is the home of approximately 2,000 Wayana and Trio indigenous peoples. The area is currently remote, and economic development is practically nonexistent, which has helped it remain intact. With GIS, indigenous people s spatial knowledge is incorporated into digital maps for conservation planning. Villagers drew polygons on georeferenced landscape maps to indicate areas of local importance. With ArcGIS, a tool was developed to count overlapping polygons to identify concentrations of important places. Seeing the signs 23 Got signs? The City of Glendale, in Los Angeles County, California, does. In fact, it had 2,000 more street signs than it thought it did. While this surprise may not seem to be a big deal to some, for Glendale City staff, not having an accurate count of their street signs could mean the difference between staying in budget and exceeding it by thousands of dollars. Glendale s 3M sign management system uses ArcGIS to help organize and display sign information easily. 3M staff determined that ArcGIS was better suited to the job than open source products.
