Through the use of wireless cyberinfrastructure technology, we are able to deploy and obtain real-time data from remote areas around the Hawaiian Islands. Water quality data and climate (weather) sensors have been placed in select locations on the island of Oahu to help us understand how human interactions affect the quality of our environment. Sensor data is collected by an Intelecell and transmitted by cell modem so that the data can be visualized on the DOFAW Portal from each location.




Geographic Information Systems (GIS) are tools to process geographically referenced data - often in order to support decisions in spatial problems. Many GIS applications can be described as spatial decision support systems. However, spatial decision support in a narrower sense requires specialized analytical functions like optimization and multiple criteria evaluation algorithms. While most GIS functions can implicitly assist decision-making, only the specific decision support features result in explicit solutions for a decision problem. With the appearance of GIS on the Internet (called WebGIS, GIS online, or Internet map servers) there is a need to define the role of spatial decision support systems (further WebSDSS) in the context of a global information network (Rinner and Jankowski). Here are the GIS visualization services that we currently host on the portal.

Mobile input allows field surveyors to use their smart phones or tablets to record information while in the field and have it automatically send the data back to the servers and have the data available for others right away.  Databases are saved and hosted on our servers and data is available through the web.
