In course exercises, you will build map algebra expressions and models to execute geoprocessing workflows and manipulate raster data to make it suitable for analysis. Learn basic concepts of fuzzy logic, a science-based approach to modelling inaccuracy in attribute data, and apply it to create a suitability model.... A table join appends all the columns from one table into the other table based on the unique ID. But a table relate creates an entirely new table. So when you select record(s) in one table, it will create a temporary table based on all the matching unique IDs.

- ArcGIS geoprocessing tool that creates a raster dataset as a file or in a geodatabase. Create Raster Dataset (Data Management) Summary. Creates a raster dataset as a file or in a geodatabase. Usage. When you create a raster dataset, you are creating an empty location to contain a single raster dataset. You can then mosaic or load raster datasets into this location. You can save your output to
- The raster toolset in the Data Management toolbox provides tools to perform raster data management and raster processing. These tools allow you to work with raster dataset properties, create raster data, and process raster data.
- The mechanism to automatically build a raster attribute table is not available in ArcGIS 9.2, as scanning all pixel values to build a raster attribute table on-the-fly is unnecessary if the unique value renderer is not used for displaying raster data in images that are getting larger.
