About IMAPS

IMAPS is a group within the DFGs' Biogeographic Data Branch responsible for the development and maintenance of innovative tools designed for the management and display of geospatial data on the Internet.

The products and solutions developed by the IMAPS group (using ESRI's ArcIMS and ArcGIS Server technologies) benefit many department programs. These programs include BIOS, CalFish, the Lands Program, and the Fisheries Branch.

The IMAPS Viewer was developed to accomplish several things:

  • provide an enterprise solution to disseminate GIS maps, spatial data, metadata, information, and images
  • permit DFG staff to easily view GIS data in a web browser
  • provide secure access to DFGs GIS data to outside users

What is an Internet Map Server?

ESRI's ArcGIS Server and Internet Map Server (ArcIMS) software are map server packages that enable spatial data be to actively displayed on a web browser. These technologies distribute GIS data and allow users to create queries and requests through a browser without requiring that GIS software be installed on the user's local computer.


Why is this significant?

Map server technology allows staff, biologists, students, community members, businesses, non-profit organizations, government, and any interested persons to view and query maps and data without having a GIS application on their personal computer. Distributing geographic information over the internet allows for real-time integration of data and provides a solution that permits a common platform for this exchange. This technology also lets you exchange, integrate, and analyze data in new ways. Users can combine data and information accessed over the Internet with local data for display, query, and analysis.


Tips for using the IMAPS Viewer:

  • Let the map viewer finish loading before you click on anything.
  • You can change the map area by zooming in (+) or out (-) using the magnifier icons.
  • In the layer list, the checkbox to the left of the layer name turns the layer on or off.
  • If you have a large screen, the viewer speed may be reduced. Shrinking your browser window will increase the Viewer speed.
  • A quick overview of toolbar functions can be viewed by clicking the "question mark" button on the right end of the toolbar. Detailed viewer instructions can then be accessed by selecting the "More Help..." tab.
