CRAM is a cost-effective and scientifically defensible rapid assessment method for monitoring and assessing the ecologcial conditions of wetlands throughout California. It takes less than half a day to assess a wetland area, and is designed evaluate the condition of the wetland based on it's landscape setting, hydrology, physical structure and biological structure.  Because the methodology is standardized for over seven types of wetlands, ecological condition scores can be compared at the local, regional and statewide landscape scales.

Help us improve CD3 to better meet your visualization and reporting needs by completing a brief survey. We're interested to learn which features you use and to read your suggestions on any desired, new functionality.

Other enhancements in this release include:

How can someone click on a map and almost immediately determine the upstream catchment area to that designated point? StreamStats is a web service provided by the US Geological Survey to perform that critical function.

The service can be seamlessly incorporated into web maps to enhance their catchment-finding abilities. In July 2015, USGS released a new version of their StreamStats service, which SFEI recently incorporated into EcoAtlas.

Fish and shellfish are nutritious and good for you to eat. But some fish and shellfish may absorb toxic chemicals from the food they eat and the water in which they live. Some of these chemicals accumulate over time in the fish and shellfish - and in the people who eat fish and shellfish. Although the chemical levels are usually low, it is a good idea to learn about advisories and monitoring in water bodies where you fish, and for fish or shellfish you eat.

The latest release of EcoAtlas (v4.1) includes two new map enhancements:

This visualization tool facilitates intuitive comparison of continuous data from around the Bay, and across a variety of analytes, to demonstrate the potential for collaborative monitoring across programs.

This release of CD3 features an advanced download tool for accessing all data for a project and the ability to dynamically generate Sum of PCBs.  Detailed instructions for using the tool's different features are provided in a pop-up box for easy reference.

Web services provide a standard way to access geo-referenced data online. SFEI now provides web services for the California Rapid Assessment Method (CRAM) Assessment Areas and California Wetland Projects data layers.Although potential uses are numerous, typically web services allow one machine to exchange data with another for timely, automated, and efficient sharing of information. Different service types provide different levels of access to the data, including serving image tiles of the data or the features and attributes themselves.
