This multisession is for all geodatabase developers and is composed of three, 20-minute subtopics: 1. Custom Raster Format Support in ArcGIS through GDAL ArcGIS has been using the Geospatial Data Abstract Library (GDAL) as a raster I/O library for reading and writing raster datasets of different formats since ArcGIS 9.2. With version 10, this becomes the primary raster I/O library and provides an open framework for third parties to add raster format support. The session will include a discussion of the GDAL data model and how this maps to ArcGIS. Attendees will learn steps and tips to implement a custom raster format in ArcGIS using C++. Level: Intermediate to advanced Prerequisite: Knowledge of raster data and C++ 2. The Developer's Guide to Working with Native Spatial Types—Oracle Applications can interact with the geodatabase through SQL. Writing efficient SQL with spatial attributes requires an understanding of the data type's architecture and operators. This session will introduce the geometry and geography data types, spatial index, and relational and geometry operators. It will focus on proper SQL syntax to ensure optimal execution and utilization of the spatial index. Level: Intermediate to advanced Prerequisites: Knowledge of SQL, basic understanding of geodatabase versioning, and experience using Oracle database 3. The Developer's Guide to Working with Native Spatial Types—SQL Server Applications can interact with the geodatabase through SQL. Writing efficient SQL with spatial attributes requires an understanding of the data type's architecture and operators. This session will introduce the st_geometry model, spatial index, and relational and geometry operators. It will focus on proper SQL syntax to ensure optimal execution and use of the spatial index.
