Building Spatial Models Has Never Been Easier!

ArcView Spatial Analyst 2 to Include New ModelBuilder

ModelBuilder enables users to quickly build and interact with spatial models.ArcView Spatial Analyst, an optional extension to ArcView GIS, enables desktop GIS users to create, query, analyze, and map cell-based raster data; derive new information from existing data; query information across multiple data layers; and fully integrate cell-based raster data with vector data sources.

ArcView Spatial Analyst 2 will include the new ModelBuilder that enables users to quickly build and interact with spatial models. Users can construct models using process wizards or by dragging icons representing data (grid themes) and functions (such as slope, buffer, and overlay) into the model document and connecting them with lines to show how the data is processed.

The ModelBuilder provides both beginning and advanced users with a set of easy-to-use tools for building various types of spatial models within ArcView Spatial Analyst. The flow diagrams created in the model are a convenient way to build spatial models and are an excellent way to document and present one's models to others.

In ArcView Spatial Analyst 2, models can be saved and rerun using different input data. They can be rerun using different function parameters that allow users to calibrate their models or examine how they perform using different sets of values.

The ModelBuilder allows users to share their models with others. This means that organizations can develop model templates for processing specific types of data and then distribute those templates to their users. Their users can then attach their own data to the model and run it using a consistent or prescribed modeling strategy.

These new tools can be used to construct spatial models in any application area. For example, organizations can use ArcView Spatial Analyst software's ModelBuilder to build land use suitability models, environmental sensitivity models, hazardous risk models, and social impact models. The user can also build models in which all of these spatial assessments are included in a single larger model.


ArcView Spatial Analyst 2 is anticipated to be released in the first quarter of 2000. For more information, contact your local reseller, Esri at 1-800-447-9778, or your regional office, or visit or Outside the United States, contact your local Esri distributor.
