Description:

Unleash the full modeling power of your geographic information system software

Geographic data models are digital frameworks that describe the location and characteristics of things in the world around us. With a geographic information system, we can use these models as lenses to see, interpret, and analyze the infinite complexity of our natural and man-made environments. With the geodatabase, a new geographic data model introduced with ArcInfo 8, you can extend significantly the level of detail and range of accuracy with which you can model geographic reality in a database environment.

Modeling Our World is the comprehensive guide and reference to GIS data modeling in general, and to the geodatabase model in particular. It shows how to make the right decisions about modeling data—decisions that will inform each aspect of a GIS project, from database design and data capture to spatial analysis and visual presentation.

You will learn to:

  • Design a geographic database that fits the project
  • Customize the database without writing code
  • Manage work flows in complex projects
  • Model diverse linear systems such as streams, freeways, or electrical grids
  • Incorporate satellite images for geographic analysis and display
  • Create three-dimensional GIS data models

Illustrated with hundreds of full-color maps and figures, Modeling Our World will be essential reading for a wide audience. Seasoned ArcGIS users and serious new users of the software will find that Modeling Our World is required reading on the path to GIS success.

For the GIS specialist, this provides a good introduction to the broader database world. For the database specialist, this book serves as a good answer to the question "what is so special about spatial?"

—Scott Morehouse, Director of Software Development, ESRI
