    Study Notes

    Advantages of Using a Geodatabase

    • Centralized repository: Data is stored in one location rather than multiple files.
    • Scalable data model: Capable of accommodating increased GIS demands by migrating to an upgraded format.
    • Increased data integrity: Spatial and attribute behaviors help reduce data entry errors and maintain relationships.
    • Support for imagery: Mosaic datasets facilitate the management of multiple images as a single entity.

    Types of Geodatabases

    • File geodatabase: Suitable for individual users or small teams, optimized for ArcGIS Pro.
    • Enterprise geodatabase: Designed for larger organizations allowing multiple users to interact with data simultaneously.

    File Geodatabase

    • A collection of GIS datasets stored in a file system folder, compatible across operating systems.
    • Default size limit of 1 terabyte (TB); expandable to 256 TB with keywords.
    • Enables simultaneous editing by multiple users across different feature classes or tables.

    Enterprise Geodatabase

    • Requires a Database Management System (DBMS) like DB2, Informix, SQL Server, Oracle, or PostgreSQL.
    • Supports versioning and replication suitable for larger organizations with unlimited users and database size.

    Geodatabase Creation Workflow

    • Evaluate data: Assess which datasets (raster, vector, or tabular) should be imported.
    • Create geodatabase: Establish a stable platform for data analysis.
    • Organize data: Implement organization using feature datasets for related themes and coordinate systems.
    • Add data: Once setup is complete, data can be added for analysis.

    Feature Class

    • A collection of geographic features sharing the same geometry type (point, line, or polygon), attributes, and spatial reference.
    • Can exist independently within a geodatabase or as part of feature datasets.

    Feature Dataset Purpose

    • Designed to store spatially related feature classes, essential for constructing topologies, network datasets, terrain datasets, or geometric networks.

    Feature Dataset Requirements

    • Must specify the spatial reference upon creation.
    • Can include feature classes of any geometry type, provided they share the same spatial reference.

    Geodatabase Basics

    • Functions fundamentally as a container for storing both spatial and attribute data.

    Geodatabase Schema

    • Schema defines the physical structure and includes rules, relationships, properties, and organization of each dataset.

    Sharing Schema

    • The schema can be exported as an XML file, facilitating sharing with other geodatabases.

    Mosaic Dataset

    • A data model for managing, viewing, and querying extensive collections of raster data.
    • Can contain diverse raster datasets with multiple formats, resolutions, and coordinate systems.

    Mosaic Layer in ArcGIS Pro

    • In the Contents pane, the mosaic dataset displays as a group layer comprising at least three layers:
      • Boundary layer: Shows the boundary of the mosaic dataset.
      • Footprint layer: Displays the footprints for each raster dataset.
