Organizing Raster Data Using ArcGIS 10

Description

Once you obtain raster data, you need to make some decisions in order to maximize its value to your organization. How will the data be used? How many people require access? Will it be served on the web or an intranet? The answers to these questions will determine which raster management solution you choose. This course introduces techniques to store and manage raster data for optimal display, fast querying, and use in GIS analysis. You will learn how to evaluate which raster formats and storage methods will best meet your needs.

Who Should Attend

GIS data managers, analysts, specialists, and others who need to manage and work with raster data.

Learn How To

• Apply different techniques to optimize raster display.
• Convert a raster from one format to another to improve access and rendering.
• Assign a spatial reference to display a raster in the correct location and align it with other data.
• Create and edit metadata to document raster data.
• Choose a storage method that supports the intended use of the raster data.
• Create a mosaic dataset to efficiently store a large collection of rasters.

To complete course exercises, you need the following software:

• ArcGIS 10.0 for Desktop (ArcEditor or ArcInfo)

Fine-tuning raster data for optimal performance

• Storing raster data in an optimal format
• Using pyramids to speed the display of raster data
• Using statistics to render your raster data
• Using compression to reduce the size of raster data
• Troubleshoot your raster data
• Prepare your raster data for optimal performance
• Understanding the spatial reference system of your raster data
• Troubleshoot each of the following spatial referencing issues
• Working with raster metadata
• Manage raster data spatial reference and metadata information

Organizing your raster data

• Organizing each raster dataset individually
• Using a mosaic dataset to organize rasters
• Using overviews to optimize a mosaic dataset display
• Organizing raster datasets as feature class attributes
• Choose an appropriate storage method
• Organize your rasters as a mosaic dataset

Completion of ArcGIS Desktop II: Tools and Functionality or Learning ArcGIS Desktop and Basics of Raster Data (for ArcGIS 10) or equivalent knowledge is required.
