1. Geographical features, such as the locations of road work and habitats of plants and animals, can be entered, searched, updated, and deleted from standard Web browsers.
2. An application can be created without any programming. The look and behavior of the map interface can be customized with configuration files, and Web scripts for data access can be automatically generated from the description of a database schema. Thus, a WebGD application can be created rapidly and at a lower cost.
3. We created the WebGD framework by using only free open-source software. Therefore, the framework is available for anyone for free use.

Natural Heritage Information System
This application provides access to information on endangered and threatened species in North Carolina. The users can contribute data that can be viewed by others. The habitat location data contributed can be exported as a shapefile. The application also allows a user to search, insert, and modify information stored in the database.

Land Manager Guide
This application helps a landowner prepare the information needed to apply for a conservation program grant through the USDA Natural Resources Conservation Service (NRCS). A land-manager can specify his/her property as a polygon on the map. The BLM parcel data and the SSURGO 2 soil data data can be accessed from the map interface.

Water Distribution Information System
This application manages information on water lines, pumps, valves, hydrants, properties, etc. The GIS data are organized into a network with water lines as edges and the pumps, valves, hydrants and so forth as nodes.

Tranportation Information System
The Corvallis Transportation Geographic Information System is a Web-based GIS/database (WebGD) application, which allows its users to query, insert, and update location-based data by using standard Web browser. The database stores information pertaining to Corvallis Transportation on the following:

1. Road Network -- Streets, Highways, One ways.
2. Rail Network
3. Assets -- Signals, sign posts, parking lots, parking meters, street lights, etc.
4. Activity -- Construction
5. Incidents -- Accidents, Spills, pot holes, etc.

Watershed Information System
The Oregon Watershed Information System provides access to current watershed information regarding monitoring sites and water quality. The map interface allows users to locate current monitoring and project sites in Oregon. A user may create and specify a new monitoring site and/or a project site through the map interface. Photos of these sites can also be viewed and uploaded. also, different types of graphs regarding water quality data can be generated by users.

Responder Locator
This Responder application can display the current locations of moving objects such as persons, buses, or fire trucks. It is also possible to download the path of a moving object as a shapefile.

Land Stewardship GIS/Database Application
The land stewardship database application is a GIS/database application for resource conservation. Data on agencies, programs, projects, management practices, tasks, cooperators, permits, concerns, actions, land parcels, species, habitats, observations of plants and animals are stored in the database, and those data can be accessed and updated with Web browsers. The map interface supports such layers as counties, cities, major roads, streets, USGS topographical maps, USGS aerial images, and land parcels for conservation.. The geospatial data for the land parcels are stored in the database, and they can be inserted, updated, and deleted by users.

Germplasm Explore and Map - GIS (GEM-GIS)
This application is for the management of genetic resources. The web-based map interface supports, in addition to navigation on maps, the following features. A user can specify the location of the habitat of an accession on the map when an accession is entered in the database. The accessions within a rectangular area specified on the map can be searched for with additional search conditions. The habitat locations of the accessions retrieved by a query can be displayed on the map. The information on an accession whose habitat location is displayed on the map can be retrieved with a mouse-click on the habitat location. This application uses open-source software tools and GIS data in the public domain so that the application can be freely distributed among developing countries.

Germplasm Explore and Map - GIS (World)
The whole world is covered with multiple-levels of maps, namely, the world map, the continent maps, and regional maps. These maps can  use different projections, and the map interface automatically selects the projection most suitable for the region whose portion is displayed.

Motels Oregon
Motels Oregon was developed to demonstrate the benefits of a Web-based GIS/database application. It is designed to help motel businesses reach customers effectively. By using an interactive map along with a relational database, a user can view any area of the map and perform database operations as their group privileges permit. For example, a motel owners are able to insert or delete her motels. In addition, she can insert, update, and modify data associated with her motels. As the background of the map, USGS DOQQs of 1-meter resolution are used. This application was first implemented with ArcIMS and ArcSDE and then reimplemented with MapServer, PostgreSQL, and PostGIS.
