parcel, which were (XXX422 m, XXX2966 m) in the UTM 
coordinate subsystem. Then, the PDA was connected to the 
server through a wireless network. The coordinates were input 
into the query interface and submitted to the server with a 
request for parcel and structure information. The server located 
the parcel that contained the given coordinates and transferred 
to the PDA a parcel map with the structure overlaid (Figure 
11a) Detailed information about the structure can also be 
displayed (Figure 11b). Several additional parcels were tested 
with functions such as real-time database updating and on-site 
visual verification of the criteria checked previously in the 
office (Figure 12).

CONCLUSIONS 
This paper demonstrates an integrated system using wireless 
technology, Internet-based GIS, and mobile mapping in coastal 
management and decision making. The system consists of three 
components: a shoreline erosion awareness subsystem, a 
coastal structure permit subsystem, and an on-site mobile 
spatial information subsystem. The developed technology can 
greatly support all parties involved in coastal management for 
decision making including coastal residents, local communities, 
and state government agencies. When integrated, spatial 
information and relevant technologies can be utilized to 
improve the efficiency of coastal management activities and to 
make more objective decisions in, for example, the permit 
approval process. Although our system has been developed and 
tested along the southern Lake Erie coast of Ohio, it can be 
adapted and employed in other coastal areas.
