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

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
