“Increasing development of coastal watersheds has altered groundwater and surface runoff patterns, and led to the progressive eutrophication of freshwater tributaries and adjacent coastal waters. Effective and properly engineered stormwater management systems represent one of the most important water resource protection strategies to counter this trend. Geospatial tools are needed to place existing and proposed development and stormwater management system (SWMS) infrastructure into a watershed context. A Geographic Information System (GIS) inventory of the existing SWMS infrastructure is a critical first step. To be most effective, this geospatial inventory, complemented by decision support tools, needs to be user friendly and readily available to a wide audience of target groups. To address this issue, we developed the StormWater Management Planning Tool (SWMPT) as a suite of on-line interactive mapping and query tools to facilitate access to data for display, assessment and analysis purposes needed for stormwater and sediment control. SWMPT is geared to meet the needs of municipalities and counties in planning and managing their SWMS infrastructure and has been implemented for Ocean County, NJ as a pilot project. To ensure that SWMPT met the needs of its identified target audience, a number of county and local partners and prospective end users were involved in the project from its inception through a highly structured design and evaluation process. The SWMPT interactive mapping tool can be accessed through”

Carl Steinitz Explains Geodesign Process in New Esri Press Book

A Framework for Geodesign: Changing Geography by Design, published by Esri Press, details the procedures that pioneer landscape architect and planner Carl Steinitz developed for the implementation of geodesign in the planning process.

Geodesign is a methodology that provides a design framework and supporting technology to leverage geographic information, resulting in designs that more closely follow natural systems.

Describing A Framework for Geodesign, author Steinitz says, “This book should be seen as a discussion with examples, intended to illustrate the issues and choices involved in the organization and management of large and complex geodesign studies and projects.”

Steinitz’ framework is shaped by a set of six key questions he developed while analyzing and refining the geodesign process:

  • How should the study area be described?
  • How does the study area function?
  • Is the current study area working well?
  • How might the study area be altered?
  • What difference might the changes cause?
  • How should the study area be changed?

A Framework for Geodesign: Changing Geography by Design

“Geodesign is a vision for using geographic knowledge to actively and thoughtfully design,” says Jack Dangermond, Esri president. “It will link and build the next generation of both geography and design. What Carl’s book does so powerfully is find the common ground between the science of geography and the methods of design. Its publication marks a milestone in the evolution of geodesign, and it will be used for many generations as a framework for creating our common future.”

Carl Steinitz is the Alexander and Victoria Wiley Professor of Landscape Architecture and Planning, Emeritus, at the Graduate School of Design, Harvard University. For more information about Steinitz and his work, read “A Conversation with Carl Steinitz” by Carla Wheeler in the April 2012 issue of ArcWatch. Steinitz will be available to autograph his book at the Esri International User Conference on Tuesday, July 24, between noon and 1:30 p.m. in the Spatial Outlet.

A New Algorithm for the Satellite-Based Retrieval of Solar Surface Irradiance in Spectral Bands

Remote Sensing, 2012, 4(3), 622-647

Richard Mueller, Tanja Behrendt, Annette Hammer, and Axel Kemper

“Accurate solar surface irradiance data is a prerequisite for an efficient planning and operation of solar energy systems. Further, it is essential for climate monitoring and analysis. Recently, the demand on information about spectrally resolved solar surface irradiance has grown. As surface measurements are rare, satellite derived information with high accuracy might fill this gap. This paper describes a new approach for the retrieval of spectrally resolved solar surface irradiance from satellite data.

“The method combines a eigenvector-hybrid look-up table approach for the clear sky case with satellite derived cloud transmission (Heliosat method). The eigenvector LUT approach is already used to retrieve the broadband solar surface irradiance of data sets provided by the Climate Monitoring Satellite Application Facility (CM-SAF). This paper describes the extension of this approach to wavelength bands and the combination with spectrally resolved cloud transmission values derived with radiative transfer corrections of the broadband cloud transmission. Thus, the new approach is based on radiative transfer modeling and enables the use of extended information about the atmospheric state, among others, to resolve the effect of water vapor and ozone absorption bands. The method is validated with spectrally resolved measurements from two sites in Europe and by comparison with radiative transfer calculations. The validation results demonstrate the ability of the method to retrieve accurate spectrally resolved irradiance from satellites. The accuracy is in the range of the uncertainty of surface measurements, with exception of the UV and NIR ( ≥ 1200 nm) part of the spectrum, where higher deviations occur.”
