Progress on Tasks
2. A DATAVIEW survey was sent out to a nationwide group of fifty-four DATAFLOW users, water quality experts, and estuarine/coastal managers querying them on proposed DATAVIEW features, possible uses for the system, and additional comments. The purpose of the survey was to rank the importance of many proposed features and collect information about additional uses of DATAVIEW/DATAFLOW in the scientific community. There were eight total respondents and the survey is still available at http://mddnr.chesapeakebay.net/sim/survey.cfm for further submissions. An edited version of the survey results can be viewed in Table 1. In general, respondents favored features that helped in data and cruise track visualization versus analytical capabilities and advanced features such as data telemetry. Users seemed to favor a quick data refresh rate of around 10 seconds. 3. A partially operational version of DATAVIEW is available, but a fully functioning prototype is not yet finished due to issues beyond DNR’s control. It was important for us to develop DATAVIEW based on the most current ESRI GIS platform. The latest version, ArcGIS 9.0, was to be released in early 2004 and was touted in summer 2003. Actual release was in the July/August 2004 timeframe, at which time Maryland DNR obtained an evaluation copy of the software. ArcGIS 9.0 includes a new integrated feature that allows for direct reception of GPS data to ArcMap. This feature has been tested successfully in the laboratory with the DATAFLOW unit, allowing real-time display of positional data. Positional data are displayed as points or lines, can be symbolized to indicate speed and bearing, and can be stored to a log file for future reference. Data can be updated as rapidly as each second. Using ArcMap and GPS in tandem provides many advantages versus traditional GPS displays. Data can be updated much more rapidly with the added power of a fully functional CPU. Custom data layers such as intricate cruise tracks, basemaps, boundary layers, and living resources parameters can be easily displayed in conjunction with real-time positional data. Using these technologies in tandem also leads the way for real-time map display of water quality data. Maryland DNR plans to conduct multiple testing methods of the real-time GPS mapping feature. In August 2004, DNR participated in a remote sensing exercise on the Patuxent River with NOAA Coastal Services Center, providing groundtruthing data for aerial observations of chlorophyll, water temperature and clarity. Due to cloud cover, satellite observations could not be collected and have been rescheduled for either September 20 or October 6. Using DATAVIEW, we will attempt to replicate portions of the exact cruise track from the August deployment (See Figure 1). We will also be able to ascertain whether the application can be run in tandem with our current system for collecting and storing the concurrent YSI, GPS and depth data. We also will use the system during either our submerged aquatic vegetation (SAV) planting (See Figure 2) or more likely with our eelgrass seed collection (See Figure 3) in Spring 2005. In 2004, DNR used an automated eelgrass seed collection boat to collect nearly 20 million seeds and plans to expand that collection in 2005 for large-scale SAV restoration activities. DATAVIEW will be used to map out the distribution of eelgrass beds in the collection zones. These zones will be saved as map layers, and will be displayed to the harvesting boat operator with information regarding current and past harvesting tracks to improve efficiency and speed of seed collection. In addition to the late release of ArcGIS 9.0, other software distribution difficulties were encountered. The ArcIMS Tracking Server, a key component for the display geographically referenced real-time data from 3rd party devices (e.g. YSI water quality monitors), is not yet available. This software component was advertised by ESRI during the proposal process in early 2003, with technical documents appearing on their website in May 2003 (www.esri.com) and a promised release within six months. Contact with ESRI during the last several weeks indicates that the ArcIMS Tracking Server release date is not solidified but will be soon and the price of the software is undetermined. Despite these delays we are confident we can accomplish the development of DATAVIEW by use of the ArcIMS Tracking Server or through other means. The end of our Water Quality Mapping field season in October will allow full access to the DATAFLOW systems for software testing.

Work Plan for Next Reporting Period
Close contact will be maintained with ESRI representatives to determine their progress (with their partner Northup Grumann) and release of the ArcIMS Tracking Server. Anticipated release will be within 2 months, but if progress is delayed, we may be forced to explore alternative programming options with the Towson University Center for GIS. Considering that the YSI data incorporation step is achieved successfully, we will begin tailoring the user interface based on user suggestions. Programming will also begin on features such as the alert system and ease of producing interpolated layers. During the process, coding and software use will be documented for creation of a user guide.
