Coastal GEMS Version 3 Final Development and Implementation
Project Description as Proposed:
The Virginia Commonwealth University’s Center for Environmental Studies has created the Coastal Geospatial and Educational Mapping System, or Coastal GEMS, through FY2003 Task 95.011 and FY2006 Task 93.04 in partnership with the Virginia CZM Program and Worldview Solutions, Inc. Coastal GEMS is a gateway, or starting point, for accessing more comprehensive coastal resource information which should be considered in planning efforts and in making management decisions. This gateway provides data and maps of the best remaining blue and green infrastructure in Virginia’s coastal zone from across state agencies and organizations, as well as information on the value and current management of those resources.
Coastal GEMS was developed using ArcIMS mapping software that was implemented to produce maps with large amounts of spatial data. This technology has proved useful until users need the ability for different basemaps, added cartography and a more fluid user interface.
Upgrading to ArcGIS Server 10 will allow the Coastal Program to use current desktop cartography available in ArcGIS Desktop to publish those maps for consumption in Coastal Gems. This allows users of Coastal Gems to view the same cartography that the Coastal Program uses to produce maps for reports and publications so there isn’t any confusion over interpretation of data.
IV. Project Workflow and items created/delivered
a. A final version of Coastal Gems will be placed into production after testing and technical points are corrected
i. Final application deployment will occur after all spatial data have been loaded into the VCU –
CES spatial data repository.
ii. Map documents will be finalized and customized with the help of the DEQ Coastal Program
iii. DEQ Coastal Program will continue to locate appropriate spatial data layers to incorporate into
1. Testing will occur from the beta application to 2 months before deployment (1/31/2012).
This will allow VCU to focus on any data and technical issues that may arise.
2. A beta application will be active and live during the upgrade to allow users to test and
comment on the application.
V. Browser Compatibility
a. The mapping components of the web site will offer browser support for Internet Explorer 6+, Mozilla Firefox 2+,
Apple Safari 2+, and Google Chrome 1+. The application will be built using Esri’s Microsoft Silverlight API for
VI. Multiple Thematic Maps
a. This solution includes the publication of many differently themed maps, based on published ArcMap
documents. These can be implemented and accessed either as standalone interfaces, or switched
between through a dropdown menu in a single common map interface. Under the single map interface,
users can switch between different thematic maps while preserving the current map extent. The
advantage of this solution is that DEQ will be able to develop new and modify existing map documents
to publish and make available to the public. Each map service will be bound to the list of available map
layers and fact sheets available for each map layer.

Project Summary Provided by Grantee:
This is the second of two consecutive grants to upgrade the VA CZM online mapping application, Coastal GEMS. The first grant (FY09 Task 93.02) was to create a draft version of the upgraded Coastal GEMS and this grant was to complete the final version.
The following tasks were completed during the grant period:
· Incorporated ArcGIS online base maps into the application.
· Implemented facts sheets/non-spatial information for each layer in the application
o An icon has been added to the end of each layer in the table of contents to denote the ability to click and
obtain a fact sheet. As more users are coming to GEMS with tablet based hardware that are not
mouse-aware, a “clickable” item needs to be present in order to obtain information.
· Added ability to add multiple map services into the viewer
o We have developed the framework and code to support multiple map services. The concept was to have 3-4
services pre-loaded into the GEMS application and have one turned on. This would allow users to turn
desired services on to display them. This will also allow users to set the transparency for each service.
· Added ability for users to customize maps by adding markup including text, shapes, polygons, lines, arrows,
icons and more.
· Added ability to produce high resolution PDF’s, and images (JPEG and PNG). PDF Maps also include custom
legend and other information/disclaimers that are needed. The map legend will be generated for the services
and layers the user is viewing at the exact time the map is generated.
· Improved tool allowing users to identify features in the maps.
· Ability to identify/select features from multiple services was finished.
· An enhancement to search by attributes was corrected so that a text/character search would not be case
sensitive since some attribute values are capitalized and some are not.
· Ability to drag services up and down in the table of contents was added.
· PDF map had disclaimer added to the map print out.
The final version of the upgraded Coastal GEMS mapping application was available online at http://gis.vcu.edu/gems3/ and will soon be put in production replacing version 2 of the Coastal GEMS application at www.coastalgems.org.
