Conceptual design of the Everglades Depth Estimation Network (EDEN) grid
Cell identifier assignment
The assignment of a unique
identifier to each EDEN cell is a difficult, but critical task. Unique
identifiers allow for continual, long-term management and analysis of the data
within the grid as it is a sub-set for analysis, data distribution, or editing
during continued improvement. Cells are uniquely identified by two different
processes. First, by definition
each cell has a unique coordinate pair for its center. However, the use of X/Y
coordinate pairs as a unique identifier is cumbersome. Therefore, a "master id" number has been assigned to each cell. Maintained as a separate attribute item,
this ID is not altered by software processing (as internally assigned and
maintained cell ID values can be).
