Search & Rescue Model and Response System

SARMAP provides rapid predictions of the movement of drifting objects and missing persons at sea. SARMAP includes the ability to deploy search & rescue units (SRUs) with search patterns and calculate probability of containment (POC), probability of detection (POD), and probability of success (POS).

Applications for SARMAP
  • Determine search area for missing vessels, persons or containers
  • Identify probable location of an accident site or lost object
  • Store home base locations of all available Search & Rescue Units (SRUs)
  • SRU Deployment and Search Pattern management
  • Floating contraband tracking
  • Reverse trajectory calculations
  • Uses RPS ASA’s own GIS or can be used in other GIS software such as ArcView®
  • Contains a database of drift behavior for a variety of objects based on the latest U.S. Coast Guard data
  • Easily interpreted visual display of search area over time
  • Performs a series of postulated accident sites to develop envelopes of likely search areas
  • Real-time data links, integrated with RPS ASA's Environmental Data Server (EDS)
  • Online web map and metocean data services
  • Links floating debris to find a lost object or an accident site
  • Rapid Response Module (RRM) or SARMAP Wizard to very quickly lead through the steps required to calculate a search area
  • Supports commercial nautical charts:
    • BSB NOAA Charts
    • MapTech Charts
    • NDI Charts
    • NOS Charts
    • British Admiralty (ARCS) Charts
    • C-MAP Charts

SARMAP Modules
  • Search Planning Tool
  • IAMSAR and MonteCarlo methods for computing drift
  • Forward and Back Tracking SAR
  • Optimal Search Planner (2008 release) - an additional module that allows controllers to:
    • Combine multiple resources for a single or multiple search target(s)
    • Cumulative POS and optimization tools to maximize probability of success
    • Integrate prior/subsequent searches to improve in future/successive search planning
  • SRU text reporting (ASCII, Notepad, Word, etc.)
  • SARMAP for ArcView®

Version 7 Enhancements :

  • Different point of departure and point of return for SRU assets – this allows the SRU deployment planning to incorporate differing start and end points for each of the SRU deployments.
  • Day time search only – this feature calculates whether it is daytime or nighttime when the user enters the search start time. If the search will be completed during daylight hours the system will allow the search to be carried out, if not, it will hold off the search until first light the following day. Note: this is a user selectable option and can be switched off if searching is required to be carried out during nighttime hours.
  • Flanking SRU search – this allows the user to deploy vessels either side of the main SRU vessel; this is done to improve the probability of success (POS) for a particular search.
  • Revised GPX exporting – to make tasking SRU’s easier
  • Additional weather and oceanographic details are now able to be displayed on the screen under the present scenario. These layers are automatically updated through a live web link.
  • Client Specific Self-locating datum marker buoy (SLDMB) drifter locations – Coming soon
  • Client Specific AIS vessel tracking data – Coming soon

Environmental Input Data

Since the quality of model predictions depends on the quality of the environmental data, a suite of tools allow the user to manage environmental data effi ciently. Specifi cally, SARMAP integrates metocean data (winds and surface currents) for accurate SAR predictions. RPS ASA is part of the development team SARMAP rescue photofor SAROPS, the latest SAR program implemented nationwide by the U.S. Coast Guard in 2007. SAROPS and SARMAP connect to RPS ASA’s EDS to obtain the latest current and wind data forecasts for the region of interest. This is very fast and allows the user to make a prediction in a matter of minutes without needing to manually enter data. Clients may request a subscription service to EDS for different data products from different sources or providers, public or private.
