| Taming the ArcIMS Multi-Service Viewer |
| Fred Pieper & Dan Deneau, Institute for the Application of Geospatial Technology |
| The ArcIMS Multi-Service Viewer is one of the sample ArcIMS HTML viewers. It supports simultaneous integration of multiple ArcIMS image map services from multiple servers to render a composite map. The value of this "cascading map server" approach is in the potential for sharing data among multiple sites that maintain and administer their own ArcIMS map services without the need for duplicating data and services at a centralized location. Such an approach makes sense for projects or user communities that require cooperation among multiple organizations or multiple divisions within an organization that individually maintain and serve geospatial data. The sample Multi-Service Viewer is a good starting point for implementing this type of de-centralized ArcIMS deployment strategy. However, it is somewhat un-refined and cumbersome to work with. To overcome the "out of the box" limitations, incorporate some user session state management features, and generally make it easier to use and administer, the sample code has been substantially modified and enhanced. The focus of this presentation is to highlight the enhanced functionality that has been developed in customizing the Multi-Service Viewer and to explain some of the specific implementation techniques used.Keywords: ArcIMS, HTML, multi-service, viewer, customization |
| Integrating ArcIMS mapping throughout a County government web site |
| Phil Thibault & Joe Rutkowski, Dutchess County, Office of Computer Information Systems |
| GEOACCESS is a map-based service designed to provide easy public access to locate an array of sites and physical features throughout the County, such as, government offices, schools, roads, hospitals, nursing homes, historic sites and museums, landmarks, trails, recreation areas, and much more. GeoAccess is unique because it is fully integrated into Dutchess County's website. It can be launched as a simple mapping application or it can be launched and focused to items of interest throughout the County web site. An example can be seen at http://www.dutchessny.gov/Municipalities/MUNtownstable.htm where each Town Hall can be located in the interactive map.This presentation will semi-technical outlining and sharing procedures and middleware code that allows web page content managers to simply create one button links that launch the mapping application and zooms into the layers and items of interest. The simple procedures and code have proven to be very successful and allows greater flexibility to our web content managers to integrate locational information into the County's web pages. |
| GIS...The Great Integrator |
| Darren Mackiewicz, CDM |
| As the idea of web services and interoperability continues to be embraced and implemented in Enterprise data management systems, the ability and usefulness of ArcIMS to facilitate this type of data sharing is increasingly being taken into consideration. With less worry about conflicting software platforms and data types in the web environment, more information, in greater detail, and managed by multiple owners, is now being integrated. Whereas in the past, it was commonplace for Assessing, Public Works , Board of Health, Community Development, Conservation, Fire & Police, and other departments to develop custom stand-alone applications for their needs, that trend is shifting towards more integrated systems. These new systems architectured around a web framework enhance communication between the departments, introduce cost saving benefits, and allow for pooling of resources to get 'more bang for the collective buck'. Of course, these systems do not pop up overnight and they do not maintain themselves. There are many considerations that need to be taken into account in designing and implementing web-based GIS systems. This presentation will touch on some of the most important of these. |
| Building Partnerships for an Internet GIS |
| Mark Wheeler, Applied GIS Inc. |
| Applied GIS, Inc. This presentation will examine the work done by the Schenectady County Department of Planning to provide GIS services to municipal governments and economic development agencies in county using Internet GIS technology. In 2000, the County began promoting the idea of deploying GIS over the web for its departments and select partner agencies. By 2002, the idea was firmly established as the Schenectady Internet Mapping System (SIMS), a membership based service for all county departments, 6 municipalities, 4 economic development agencies, and the local community college. This presentation will include details on the methods used to deploy the system, address the functional requirements of individual partners, enlist new partners, and how a pricing structure for membership was instituted. |
| Municipal GIS Web-sites: The State of the Art |
| Michael Terner, Applied Geographics, Inc. |
| GIS web-sites are not experimental luxuries any more. The paradigm has shifted and a GIS web-site is the primary mechanism by which most end-users gain access to GIS capabilities and to see GIS data sets. This presentation will focus on advances in web mapping technologies that have continued to allow better sites to be built. The presentation will use live demonstrations and will present several case studies to address issues such as: Providing integration with an organization's general web presence, Providing advanced integration with relational database systems outside of ArcIMS, Achieving multiple table joins, Allowing advanced one-to-many/many-to-one query capabilities, Maintaining high degrees of performance and usability, Allowing on-line markup and simple editing of features through a web application |
| Westside Embraces Open Source Software and ArcIMS to go Online |
| Mohammed A. Hoque, Town of West Springfield, MA |
| Open source and free software helped town of West Springfield, MA achieved its goal of disseminating GIS & Tax information over Internet for businesses and residents. ArcIMS, in concert with Apache, Tomcat, JSP and JDBC on server side, and HTML and JavaScript on client side, made an integrated and live cross-platform communication between GIS and Tax database. Web server, running on Linux Red Hat, is hosted inside the town hall and connects to Windows servers via Samba. The website is designed to be simple, functional and smaller in size for faster download even with modem connection. When user search parcel by address or location, ArcIMS and JSP returns map, tax information and photos by accessing Oracle database on Windows server, and link to print tax map. It also saves trips to Assessor department by providing link to digital copy of Sale Deeds when accessed by town officials.Keywords: ArcIMS, Parcels, Linux, Windows, JSP |
