Polygonal networks are very common on the Martian surface, and their location has been correlated with the presence of ice in the soil.
The most accepted hypothesis for their origin takes into account their similarities to polygonal networks on Earth, which mostly occur in periglacial areas. Ice-wedge
polygonal networks are being studied in Svalbard, Norway, in the framework of project ANAPOLIS. Field study and characterization of these structures involves the local
detailed delineation of networks resulting in large amount and variety of data collected, with a common reference system. The construction of a GDB for the Adventdalen
data allowed linking the raster, vector and numeric data, making them available in an organized manner, offering a intuitive access to the multidisciplinary teams involved in
the project.

VIII. REVERSE ENGINEERING A GEODATABASE TO A DIAGRAM AND A DIAGRAM TO A GEODATABASE
CASE TOOLS
XML DOCUMENT
ARCCATALOG® The computer-aided software engineering (CASE) tools subsystem allows to create blueprints of
the structure of the geodatabase using a graphical language—the Unified Modeling Language (UML).
The use of GDB has many advantages, it ensures that no excess (or duplicate) information is stored, has much faster raster visualization
The Svalbard GDB schema was exported to Microsoft Visio® with the use of Geodatabase Diagrammer tool, the graphics are automatically generated in MS Visio® to construct the data model.
with pyramid building and data occupies less space on disk. The Svalbard uncompressed GDB, occupies 12.6 GB of space disk, the same data in a normal windows
folder, occupies 28.8 GB. A GDB is designed for maintenance and performance. Using topology, network rules and spatial relationships it was possible to add behavior to
the GDB. Additionally the interoperability with CASE Tools has been of great value in the construction and updating of the Svalbard GDB.
VII. SHARING AND MAINTAINING
VI. ADDING BEHAVIOR TO THE GEODATABASE
AND ENFORCING THE INTEGRITY OF THE DATA
Sub-types - Setting a default value for the respective Ortophotomap number that
will automatically apply when creating new polygons features.
AtributesDomains defining a logic range for the areas field attribute of
Polygons_contours.
Split policy - for polygons areas field attribute - Geometry ratio.
Merge policy - for polygons areas field attribute - sum.
Relationships - defining how rows in Polygons_contours table can be associated
with rows in Polygons_centroid table, with a direction of cardinality, one-to-one.
Topology rules - Polygons-contours -( Must Not Self Overlap).
Feature-linked geodatabase annotation - If the feature polygons_contours is moved
or deleted, the annotation with field nº moves with it or is deleted.
