DevelopmentDevelopment::First conceivedFirst conceived
In: 2001
By: ESRI, Duke, NOAA, and Oregon State
Since then it has primarily handled by Oregon State
Goals:Goals:
To create a data model that applies to coasts, estuaries, marginal seas, and the deep ocean. Primarily to be used by: government, military oceanographers, coastal resource managers, nautical archaeologists, marine conversationalists, fisheries managers, and so on.
Real World Applications:Real World Applications:
Used in modeling marine mammal migrations, oil spills, and algae blooms, and new uses are derived constantly

Thematic Thematic Layers:Layers:
Use: Representing the path a ship or animal took. Either on the surface or seafloor.
Spatial Relationship: Tracks have a direction with time stamps.

Data Model Data Model MaturityMaturity
Arc Marine is has matured into a well organized and functional data model,but it is not meant to be a solution for all needs. It is meant to be a startingpoint and can be used in conjunction with Arc Hydro, Groundwater, Climateand Weather, and more.
Challenges: *The ocean environment is best modeled in a 3D environment, while technology is catching up to the needs for 3D modeling, processing times can still lag. *How to best deal with the temporal and dynamic properties of shoreline and coastal processes.
Exploring the Exploring the data:data:I used the sample data included in the Arc Marine tutorial
link: http://dusk.geo.orst.edu/djl/arcgis/ArcMarine_Tutorial/
Goal of the tutorial:
Model the transect path of a remotely operated vehicle and
the observations made during the transect
Tracks Data Description: Path of R.O.V
Attributes: Feature Code StartDate EndDate TrackID LocalDesc
Coastline Data Description: Coastline of Monterrey
Bay California. Attributes: Shape Object ID Feature ID Feature Code VDatum Shape_Length
Vehicle Data Description: R.O.V Attributes: ObjectID VehicleID Name Category
Cruise Data Description: Project
Description Attributes: ObjectID CruiseID Code Name Purpose Status Description StartDate EndDate ShipName
Setup Schema Must define a coordinate system
Procedures:Procedures:
Matching Data Match fields from feature class to source data
Importing Objects Import objects into the database
Creating Relationships One to Many relationship in this tutorial
ProblemsProblems
Create a Raster Catalog Importing Rasters
Had trouble with this step. I could not get the raster layers to import into the Raster Catalog,apparently it was a known issue. I added the layers later into ArcMap, then came back and retried this step and it worked fine.
Dynamic SegmentationDynamic SegmentationWhat is it? Transforming events stored in a table into a feature that can be displayed on a map. -Geocoding Addresses -Display Route Events -Display XY Data
