The SCATalogue app is a creation of the California Department of Fish and Wildlife, Office of Spill Prevention and Response (CDFW, OSPR). SCATalogue simplifies the collection of shoreline cleanup assessment technique (SCAT) data during a spill response. Survey data attributes are based upon the National Oceanic and Atmospheric Administration (NOAA) standard SCAT shoreline oiling summary (SOS) paper form. A SCAT survey is a collection of SCAT data for a length of shoreline which is referred to as a shoreline segment. SCATalogue is designed to support spill response in the marine environment. The survey data can be transferred via email, via iTunes or other methods if available. These other methods are dependent on the user's and/or user's organizational iPad setup and/or information technology (IT) protocols. SCATalogue is, and was designed for use on an iPad, specifically the iPad mini which is used by the California Department of Fish and Wildlife, Office of Spill Prevention and Response's field response staff. CDFW OSPR's geographic information systems (GIS) unit utilizes ESRI ® GIS software almost exclusively. Data output is in JSON format. Data containing geographic/spatial data is formatted in Environmental Systems Research Institute (ESRI ®) geoJSON format. This output can be converted into to feature class(es) using ArcGIS Desktop's © ArcToolbox's "JSON To Feature" tool. CDFW OSPR GIS processes the JSON/geoJSON output from SCATalogue using this tool and other custom scripts/tools in ArcGIS Desktop © software. For further information about SCATalogue, please contact CDFW OSPR GIS at osprgis@wildlife.ca.gov. Continued use of GPS running in the background can dramatically decrease battery life.
NLE Calc
This utility calculates the Recommended Weight Limit (RWL) and Lifting Index (LI) for single or multiple lifting tasks based on the NIOSH Lifting Equation. It helps assess physical stress to prevent low back musculoskeletal disorders.
- Calculates Recommended Weight Limit (RWL)
- Calculates Lifting Index (LI)
- Calculates Composite Lifting Index (CLI)
- Based on Revised NIOSH Lifting Equation
- Assesses physical stress for lifting tasks

The NIOSH Lifting Equation calculator (NLE Calc) is based on the Applications Manual for the Revised NIOSH Lifting Equation (Pub No. 94-110) and can be used to calculate the Recommended Weight Limit (RWL) and for single or multiple lifting tasks. The Lifting Index (LI) is an index of the relative physical stress for performing a single lifting task and the Composite Lifting Index (CLI) is an index of the overall physical stress for performing multiple lifting tasks. NIOSH recommends an LI and a CLI of 1 or less for protecting workers from physical stress related to development of low back musculoskeletal disorders. Please refer to the Applications Manual for the Revised NIOSH Lifting Equation publication for examples and details on how calculations are performed and what the results imply.
