Novel approaches to health care delivery that leverage community resources could improve outcomes for children at high risk for obesity.
We describe the process by which we created an online interactive community resources map for use in the Connect for Health randomized controlled trial. The trial was conducted in the 6 pediatric practices that cared for the highest percentage of children with overweight or obesity within a large multi-specialty group practice in eastern Massachusetts.
By using semistructured interviews with parents and community partners and geographic information systems (GIS), we created and validated a community resource map for use in a randomized controlled trial for childhood obesity. We conducted semistructured interviews with 11 parents and received stakeholder feedback from 5 community partners, 2 pediatricians, and 3 obesity-built environment experts to identify community resources that could support behavior change. We used GIS databases to identify the location of resources. After the resources were validated, we created an online, interactive searchable map. We evaluated parent resource empowerment at baseline and follow-up, examined if the participant families went to new locations for physical activity and food shopping, and evaluated how satisfied the families were with the information they received.
Parents, community partners, and experts identified several resources to be included in the map, including farmers markets, supermarkets, parks, and fitness centers. Parents expressed the need for affordable activities. Parent resource empowerment increased by 0.25 units (95% confidence interval, 0.21-0.30) over the 1-year intervention period; 76.2% of participants were physically active at new places, 57.1% of participant families shopped at new locations; and 71.8% reported they were very satisfied with the information they received.
Parents and community partners identified several community resources that could help support behavior change. Parent resource empowerment and use of community resources increased over the intervention period, suggesting that community resource mapping should inform future interventions.

This paper presents the preliminary achievements of an on-going effort to develop a free archive of ground-based air pollution data collected from real-time monitoring stations in China and India. The study also includes the development of a methodology for processing air pollution measurements from streaming raw data into pollution exposure maps. Results are applicable to public health studies at city and county levels.

CGA at 2017 FOSS4G The CGA is hosting 28 workshops for the conference on Monday and Tuesday (August 14 and 15) at Harvard University. CGA staff will teach one workshop: Building SDIs and geoportals with GeoNode and a search engine, and make two presentations: The Billion Object Platform (BOP): a system to lower barriers to support big, streaming, spatio-temporal data sources and Maintaining Spatial Data Infrastructures (SDIs) using distributed task queues. | |
2017 International Symposium on Spatiotemporal Computing The 2017 International Symposium on Spatiotemporal Computing was held on Harvard campus on August 7th to 9th. More than 70 scholars from five countries and 41 organizations attended the event. The symposium was organized by the NSF I/UCRC Spatiotemporal Innovation Center and hosted by Harvard’s Center for Geographic Analysis. There were 44 oral presentations, and a dozen live demos and poster presentations at the event, including two projects by CGA staff. More information is available on the CGA website. Video recordings of the plenary sessions will be posted online soon. | |

Share with GIS Faculty: Esri student licenses are now orderable for universities and colleges with an Esri site license Faculty at Esri site license institutions may now order complimentary 1- year ArcGIS Desktop student licenses for your students. ArcGIS Desktop 10.5.1 and earlier versions are now available to request from here. The one year licenses may be installed on students personal computers and include a single use license of ArcMap, ArcGIS Pro and the associated ArcGIS extensions. The one-year student licenses given to instructors are valid for 12 month from the day of authorization, while Harvard site license also provides single use licenses which all expire on the same day in July each year. | |

GIS is not just for mapping. As an information system and science, it also provides tools and perspective for learning what spatial data can tell us about the world and its geography. It leverages the special characteristics of spatial data and processes to derive more insight from data than a non-spatial approach can do. This course builds on introductory concepts and skills of spatial data management and cartography to cover a range of exploratory, statistical, and predictive spatial analysis techniques, using publicly available and student-prepared datasets. Students use ArcGIS, QGIS, and other tools to prepare and perform the analyses, then visualize and interpret the results. Emphasis is on learning the interpretive strengths and weaknesses of different analysis techniques and drawing valid conclusions from them in diverse applications.

The history of maps and mapping from the age of Enlightenment to the era of GIS and GeoJSON. We will examine the way states and individuals have used maps to create ideas, shape policies, and generate political and cultural capital. We will also study the production of maps ? both print-based and digital ? by historians themselves. What new insights about the past can we gain by mapping it? How are innovations in cartographic technology changing the way historians think and write? In today?s interactive digital environments, where does the map end and history begin?

Urban planners engage in many complex processes that defy easy representation. This course provides first-semester urban planning students with the graphic and technical skills needed to reason, design and communicate these processes with geospatial data. This knowledge will be embedded within a larger critical framework that addresses the cultural history of categorization, data collection and cartography as tools of persuasion for organizing space.Visual expression is one of the most compelling methods to describe the physical environment, and students will learn techniques specifically geared towards clarifying social, political and economic dynamics and how they relate the structuring of spaces. The class will introduce fundamentals of data collecting, data formatting and data importing into a Geographic Information System (GIS) environment.Students will gain familiarity with the technical tools essential to GIS for making maps and exploring relationships in the physical, regulatory and demographic dimensions of the landscape. Within GIS, students will learn the basics of geospatial processing to produce new forms of knowledge in support of ideas about urban planning and design. Desktop publishing tools, including Adobe Photoshop, Illustrator, and InDesign will be used to distil ideas into effective graphic presentations. The class will also advance techniques for representing form and space through diagramming and three-dimensional modeling programs.Students will be introduced to workflows that demonstrate how to move effectively between data from these platforms and modes of representation. Class lectures will be complemented with technical workshops.Objectives:1. Establish a conceptual framework for critically engaging the practices of mapping and data-visualization;2. Provide a basic understanding of tools and techniques needed to reason, design and communicate with geospatial data;3. Develop students’ skill and confidence for visualizing the complex processes, flows, and dependencies unique to the planning discipline.Prerequisites:Enrollment in the Urban Planning program.
