Sacramento River Watershed Digital Atlas Project

From its headwaters near Lakeview, Oregon to the Sacramento/San Joaquin Delta, the Sacramento River takes its water from 27,000 square miles of drainage area. One of the largest watersheds in the United States, the River drains much of Northern California, providing water for drinking, farming, and recreation for tens of millions of Californians.

Thousands of people - ranging from biologists, policymakers and engineers to farmers, fishermen, and foresters - work on water-related projects in Northern California, and hundreds of millions of dollars have been spent to improve water quality, fish habitat, and recreation. Coordination between these many parties is difficult - though hundreds of thousands of reports, projects, plans, maps, and photographs describe the watershed, there has been no central repository or index for this information.

The Sacramento River Watershed Program (SRWP) has recently designed information-organizing tools which allow users to contribute information about water and resource management-related projects to a publicly-built digital archive, and to tag this information on interactive maps.

As part of this undertaking, NorthTree GIS designed, built, and maintains a digital atlas that allows users to explore data, documents, and other information about the Sacramento River Watershed. This effort is a key feature of SRWP's watershed resource library - using maps to index a massive online database of maps, GIS coverages, documents, photos and other resources.

Incident Mapping Professionals

NorthTree GIS began in 1999 as a emergency response mapping service providing onsite GIS mapping equipment and techs to Incident Management Teams responding to large Western wildfires. Since then we have worked on some of the largest wildfires in American history. Our fire maps compile information from any number of sources including: people on the ground, helicopter GPS, infrared overflight, and sometimes, just a line drawn in Sharpie on an old topographic map. We take in intel until about midnight on most fire assignments, get infrared data around 2-3 a.m. (if we're lucky), and have 50-100 full size maps printed by the time people show up for a 6 a.m. briefing.

Working wildfires has taught us good stress mangement, rock-solid file management, and a lot about how to work with people on tight deadlines. Now that we have diversified into non-emergency GIS work, we like to think that these skills set us apart - that our emergency-response skills can help keep your non-emergency project from turning into one.

NorthTree GIS techs designed maps used to brief President Bush during the 2003 Cedar Fire, in San Diego County.
