1 GLOS HarborView A mapping mashup that supports recreational boating on the Great Lakes David Hart GIS Specialist Aquatic Science Center University of Wisconsin-Madison GLOS Annual Meeting Ann Arbor, Michigan Monday, April 6, 2009

2 Overview of the Presentation Vision Application Future Directions Panorama, McKinley Marina 11/7/06 I drove from Madison to Milwaukee on a beautiful day in early November When I got within 500 yards of Lake Michigan, I entered a fog bank so thick it was hard to figure out where I was.

Boaters use a variety of independent (and sometimes insufficient) sources of information to make decisions

3 The Current Problem There are over 4 million boats registered in the eight Great Lakes states (approx. one-third of U.S. total) There is a wide variety of experience levels in the Great Lakes boating community. Boaters use a variety of independent (and sometimes insufficient) sources of information to make decisions about when and where to go boating. This can lead to missed opportunities, inefficient trips, and impaired safety.

communities that seeks to support safe and pleasurable recreational

4 What is HarborView? HarborView is a web map viewer focused on Great Lakes harbor communities that seeks to support safe and pleasurable recreational boating. It integrates weather images and coastal observations with maps and info about recreational and cultural attractions.

5 User Needs - Mariner Interviews Interview #1 Milwaukee Yacht Club, 48 Trawler Yacht sails every year in northern Lake Huron active in the Coast Guard Auxiliary keen interest in real-time weather information for the GL What information do you need to help make a decision to go boating? weather (current conditions and forecasts) ports and facilities (destinations) safety and navigation (aids to navigation w/ current status)

6 User Needs - Mariner Interviews What are some of your current sources for this information? Great Lakes Open Lake Forecasts, NWS ( Nautical Charts (buy pre-loaded at West Marine) Coast Pilot, NOAA old school dissemination, but can be downloaded now ( includes aerial photo of harbor Light List, U.S. Coast Guard ( The key question -- Is the light still working today? for example: In Ludington, is the North lighthouse still operating as advertised?

7 User Needs - Mariner Interviews What are some of your current sources for this information? Great Lakes Cruising Guides, Lakeland Boating ( example: Lake Michigan Ports o Call accommodations, sightseeing, emergency, transit, repairs Great Lakes Cruising Club ( membership organization, requires login appoints port captains who prepare harbor reports western shore of Lake Michigan has one report) Michigan Harbor Guide, Michigan DNR way ahead of Wisconsin

8 User Needs - Mariner Interviews General Insights Port facilities info (are there marinas? power supply? where are the nearest services?) Plan trip on availability of dockage can be similar to hotel reservations Visibility and waves are a huge issue for boaters. Boaters are comfortable with zulu time. Wave steepness very important, GL waves have very short, rapid period. Oceans have swells

9 User Needs - Mariner Interviews Recommendations for HarborView Prototype Latest obs layer link to NOAA buoy report in dialog box, from buoy report get wave height and period fog, humidity, temperature vs. dew point, wind is critical, barometric pressure ok, water temp Need geo-regulations e.g.) vessels over 40 must go 4 mph in Milwaukee harbor and for 30 minutes before and after fireworks = no wake Need oblique view of harbors e.g.) Pictometry Webcams are becoming very important Regarding integration of information how old is this info? How do boaters get internet access in coastal waters? Help small communities get public wi-fi, should be in all downtowns

10 Balancing User Needs & Technology GLOS application developers discussed several web mapping technology options in April 2008 OpenLayers Flash Chameleon/MapServer The Google Maps API emerged as a good candidate provided a good base map incorporated distributed data sources (KML ) search capabilities It is important to note that web mapping technology is changing very rapidly and we often need to experiment to match the appropriate technology to user needs.

11 HarborView Data Catagories Base Maps nautical charts, orthophotos, topographic maps Satellite Imagery MODIS, NEXRAD reflectivity Model Output wind fields, water level surface, temperature, currents Observations water level stations, buoys, met stations, ships Recreation/Cultural Features boat ramps, lighthouses, parks, beaches, shipwrecks Other webcams, panorama photos, lightning strikes
