Welcome to ICE MAPS, an interactive, natural resources query system for the state of California. This system uses several Web techniques that allow you to query the GIS system and databases here at ICE. The results include maps and hyper-links to other sources of information related to your choices.
The system is used in two steps, or modes. The first is navigating to the geographical region of interest. The second step is retrieving data from the various categories which are available for the specified region, leading to a finished map and other output.
The system starts in Navigation Mode. You may progressively refine the boundaries of the region of interest (as explained on the Instructions page). When you are satisfied with the boundaries, you switch to Data Retrieval Mode. In this mode, you choose from the available data categories and then request the system to "Retrieve Data". The results are a map and links to related information. Plans for future enhancements include tabular output.
The ICE MAPS data layers come from a number of different sources. Some GIS data sets were developed at ICE, while others are made available courtesy of state and federal agencies. In particular, the California Department of Fish and Game (DFG) contributed several of the layers. Many additional data sets are provided by the DFG through a license agreement with the Teale GIS Technology Center .
Brief, descriptive meta-data for each data layer is available by selecting the name of the layer. From there, a full meta-data description from the source organization is accessible via another hyper-link.
We'd like to acknowledge assistance from Prashant Bhandary (prashb@rta.nsw.gov.au) for contributing the gra to gif driver which we modified to work on our system. Mr. Bhandary works as a member of the Spatial Systems Solutions group for the Roads and Traffic Authority, NSW, Australia.
