Vegetation Mapping
The Collective was awarded a three-year contract to create a vegetation map for 2.2 million acres in the far northeast corner of California with portions of the map in Siskiyou, Shasta, Lassen, and Modoc counties. The map will assist land managers in several ways including invasive species management, fire management/prescribed burns, restoration, migration corridor connectivity, sustainable agricultural practices, maintaining population goals for fishing and hunting, and protecting and preserving sensitive plant and animal communities.
Critical Research to Assist in Finding Human Remains within Sacramento River
The Sacramento River is California’s largest river and claims dozens of lives each year due to drownings, boat accidents, and suicides; it is also a common body dump location for homicide victims. The "Fluvial Transport of Human Remains: Forensic Application of a HECRAS Model for Predicting Search Parameters for Human Remains Recovered from the Sacramento River, CA" study conducted by the Collective’s GIS team helped develop a predictive fluvial transport model for locating human cadavers within the southern half of California's Sacramento River.
The research adapts an existing hydraulic model (Hydrologic Engineering Center's River Analysis System, HEC-RAS) to generate a predictive model of fluvial transport rates of victims who entered the river with known dates and locations under low, medium, and high flow rate conditions.
