“While sea level rise is a world-wide phenomenon, mitigating its impacts is a local decision-making challenge that is going to require site-specific remedies. Faced with a variety of conflicting mandates and uncertainty as to appropriate responses, local land use planners and managers need place-based decision support tools. With the increasing availability of high-resolution digital elevation models and the advancing speed and sophistication of web-based mapping, a number of web geographic information systems (GIS) tools have been developed to map and visualize what areas of a coastal landscape will potentially be flooded under different scenarios of sea level rise.

Example of unimpeded vs. impeded horizontal tidal marsh retreat zones in the NJFloodMapper viewer under six feet of projected sea level rise.

“This paper presents a case study of one such WebGIS application, NJFloodMapper (, with a focus on the user-centered design process employed to help our target audience of coastal decision-makers in the state of New Jersey, USA, access and understand relevant geographic information concerning sea level rise and exposure to coastal inundation, as well as assess the vulnerability of key infrastructure, populations and natural resources within their communities. We discuss the success of this approach amidst the broader context of the application of WebGIS tools in this arena. Due to its flexible design and user-friendly interface, NJFloodMapper has been widely adopted by government and non-governmental agencies in the state to assess coastal flooding exposure and vulnerability in the aftermath of a recent destructive coastal storm. However, additional decision support tools are needed to help coastal decision-makers translate the place-based information into concrete action plans aimed at promoting more resilient coastal land use decisions.”

Group on Earth Observations (GEO) Sessions and Special Exhibit at the 2014 Esri User Conference

Esri logoGroup on Earth Observations (GEO) Special Exhibit

Come learn about the Group on Earth Observations (GEO). Comprised of 90 member nations, the European Commission and 77 Participating Organizations who are working together to unleash the power of open Earth observation data.

Designed to improve the quality of life of people everywhere, GEO focuses putting sound science to work across nine essential areas: agriculture, biodiversity, climate, disasters, ecosystems, energy, health, water and weather.

GEO’s mandate is to drive the interoperability of many thousands of space-based, airborne, and in situ Earth observations around the globe.

Esri in cooperation with Institute of Atmospheric Pollution Research of the National Research Council of Italy (CNR-IIA) have team together to make it easy for the Esri user community to benefit from and to contribute to GEO. Esri has also supported the work of the Open Geospatial Consortium (OGC) in their contributions to the work of GEO.

Come see the GEO Data Access Broker of CNR-IIA Florentine Division and Esri Community Portal for GEO to see how you can participate; and to learn about the good work of GEO.
