  1. Building Geodatabase of the Brazos basin For the application of WRAP and SWAT By Seongha Hwang April 17, 2002

  2. Contents • Introduction • What is Geodatabase? • How to create? • Relationship class • Application • Result • Next step • Question

  3. Introduction • This study deals with building Geodatabase of the Brazos river basin for the application of WRAP and SWAT model. • Basic Concept and Creating a new personal Geodatabase.

  4. What is Geodatabase? • Geodatabase model - A data model included in ArcGIS for representing geographic information

  5. Categories of Geodatabase • Personal Geodatabase - many readers and a single editor • Multiuser Geodatabase - can be read and edited by multi users

  6. How to create? • Creating a new geodatabase from scratch • Migrating existing data into the geodatabase • With CASE tools

  7. Creating a new geodatabase from scratch • No data or part of data • Designing and managing items with ArcCatalog

  8. Migrating existing data into the Geodatabase • Shapefiles, Coverages, INFO tables, and dBASE tables ArcCatalog Convert to Geodatabase

  9. Building Geodatabase with CASE tools • CASE : Computer-Aided Software Engineering - Tools and techniques that automate the process of developing software systems and database design

  10. Relationshipsbetween objects • A relationship class explicitly defines the relationships between objects in a geodatabase

  11. Application- Brazos river basin

  12. Datasetsfor the Brazos basin • WRAP • SWAT

  13. Datasets for WRAP • DEM (30X30) • Control Points(3316) • Stream network(NHD) • FDR • Curve Numbers • Precipitation(mean annual)

  14. Datasets for SWAT • STATSGO • National soil table • National Land Cover Dataset • Land use table • Weather Stations • Weather data

  15. Creating Brazos Geodatabase • ArcCatalog in ArcGis - Creating a New personal Geodatabase

  16. Creating a new personal geodatabase

  17. Importing existing data • In Data folder - Export the data into Geodatabase • In Geodatabase - Import the data from their folder

  18. Import and Export

  19. Convert and Store • Using import or export tools, conversion of data into Geodatabase is performed automatically, then data are stored in the Geodatabase.
