Common Operating Picture (COP) Concept

Environmental Sensitivity Index (ESI) Mapping

Regional Case Studies in Suriname, Guyana, and Trinidad

OUTLINE


Common Operating Picture:• Platform based on GIS technology that provides a single source of

data and information for situational awareness, coordination, communication, and data archival to support emergency management, response personnel, and stakeholders involved in or affected by an incident (IOGP, 2015).

COMMON OPERATING PICTURE (COP) CONCEPT

• Collection, management, and visualization of environmental data is crucial for sharing information about a project, region, or incident

• Data trapped in traditional maps and reports is not readily accessible to decision makers and stakeholders

Data Layer Diversity

• IOGP and Esri guidance enumerate 256 data layers for environmental preparedness

• 70% of these data layers are available in advance of an incident

Examples of Pre-Incident Data Sources

• Environmental and Social Impact Assessments (ESIAs)

• Environmental Baseline Studies (EBSs)• Oil Spill Response Plans (OSRPs)• Environmental Sensitivity Index (ESI) maps• Modeling results• Literature reviews• Desktop studies• Third-party data• Publicly-available data


• Customized web portal and tools• Optimized for projects, regions, users• Designed and populated by subject matter experts• Centralizes data, documents, layers, and feeds• Serves as a Common Operating Picture (COP)

Data management, accessibility, and visualization in a secure, web-based environment

ENVIRONMENTAL DATA AND GEOSPATIAL SERVICES (EDGS)

Data Structure, Organization, and Access


• Any file, document, or image can be linked to a spatial feature or uploaded into a library

• Photos and videos can be spatially associated as an “attachment” or through the Report Tool

• Users can upload documents and associate with features

• Recover photos of a specific location from a database of thousands of images

• Interface with Huddle, Sharefile, or other DMS links enables automatic updating of most recent file (no need to re-associate or reload to the web portal)

Document Management System (DMS) Linkage

EDGS TOOLS AND FEATURES


ROV videoROV location

• Integrate video imagery, navigational data, and metadata

• Manage, view, and deliver video in a web-based spatial platform

• Imagery can be from a range of platforms (UAV/drone, ROV, diver video, fixed wing aircraft, helicopter, tethered balloon, and others)

• Meet metadata requirements from the Motion Industry Standards Board (MISB)

• Digitize points, lines, and polygons directly on video frame

ENVIRONMENTAL SENSITIVITY INDEX (ESI) MAPPING

ESI Mapping for Environmental Preparedness and Response

• Shoreline type

• Sensitive ecosystems and biological resources

• Human use resources

• Logistical and operational resources

(IPIECA 2012)



Shoreline Type

• Classification based on substrate type and degree of wave exposure

• Classified from least sensitive (1) tomost sensitive (10)

o Lower numbers are less sensitive to oil spills –natural processes likely to assist dispersion and clean-up

o Higher numbers are more sensitive – low energy, fine sediments, organic material



Biological Resources

• Wildlifeo Birdso Turtleso Marine mammalso Fisho Invertebrates

• Habitatso Essential or critical habitato Protected areas



Human Use

• Human Activitieso Fishing, surfing, divingo Recreational beaches and parkso Aquaculture

• Infrastructure/Transportationo Facilitieso Water intakeo Wells, platformso Commercial activities

ØTraditional approach is difficult to employ in remote or inaccessible areasØCost and time prohibitive on a regional scale


REGIONAL SENSITIVITY MAPPING


REGIONAL CASE STUDY: SURINAME AND GUYANA

Regional Mapping Objectives

• Define ESI shoreline types on the basis of visual interpretation of Esri World Map satellite imagery(1:2500 scale)

• Identify and centralize authoritative sources for other data layers and imagery

• Publish to web-based COP

CONCLUSIONS

• Collection, management, and visualization of environmental data is crucial for sharing information about a project, region, or incident

• Centralizing data and imagery in a Common Operating Picture unlocks data from maps and reports

• Regional methods for data integration enhance the accessibility and meaning of data
