Aggregation Class

The categories by which variables can be aggregated and disaggregated.

Aggregation Member

Category

The general categories of data being collected (e.g., oceanography, water quality, fishing).

Country

The countries for which data have been collected.

Feature

The list of non-point spatial features (i.e., lines and/or polygons) for each named location.

Junction Aggregation Member Reading

Table required to create a many-to-many relationship between the Aggregation Member table and the Reading table.

Locality

Specific localities, or communities, within each region in a country (e.g., pilot project areas).

Location

Specific locations where samples were collected (e.g., “Sampling Station #1”, “Bucco Reef”) – each named location can refer to one or more points, lines or polygons.

Lookup

The possible values for variables that use a lookup.

Measurement Set

Sets of measurements collected at a specific date, time and location.

Point

The coordinates (latitude and longitude) associated with each point-based location.

Reading

The values measured for each variable in a measurement set.

Region

The geographic regions within which data have been collected. This might include a parish or other administrative unit within a country.

Source

The sources of the information for each measurement set.

Subcategory

The general subcategories of data being collected (e.g., coral substratum, mangrove litterfall).

Theme

The ArcView map themes on which spatial features are found.

Theme Field

The ArcView theme attribute fields used to identify spatial features.

Theme Field Type

The possible ArcView field types.

Theme Type

The possible theme types (e.g., line, polygon, images).

Value Boolean

Values for readings stored as boolean.

Value Double

Values for readings stored as double precision.

Value Long

Values for readings stored as long integer.

Value Lookup

Values for readings stored as a lookup.

Value Text

Values for readings stored as text.

Value Theme

For values stored in an ArcView theme table, indicates the theme field containing the value data.

Value Type

The possible places where value data can be stored.

Variable

The substances or properties being measured (e.g., dissolved oxygen, % sponges, # of craft boats).

Variable Type

The possible variable types (e.g., boolean, double, long, etc.).
