The results are defendable and users can easily save the settings for reuse, comparisons, and auditing purposes. Advanced Class Location analysis logic, such as structure-by-structure validation or visual sliding class assessment unit (e.g. one mile), makes this a perfect tool for those needing to run Class analysis on their pipelines.

Capabilities include: 

• Gathering Class calculations
• Built-in advanced validation tools
• Full integration with ArcGIS Pro

This flexible tool can run a standard sliding class calculation with or without clustering, utilizing attributes of structures to drive each analysis. As results are generated, users can view them as a map and easily export the data. The user can define exactly what data to include for each portion of the analysis and only the features that meet the criteria specified will be used.

The Class Calculator for ArcGIS Pro is designed to streamline the workflow process wherever possible. Powerful analysis tools are also provided to understand, verify, and interpret the analysis results. Users can run multiple analyses over the same area, with different inputs, to perform a “what if” analysis and compare the results side by side. It can even allow users to compare results and identify areas of Class change.

Integration with Esri’s ArcGIS Pro brings several advantages:

• Easily export the results in standard Esri formats.
• A clear and comfortable user experience.
• Leverages ArcGIS Pro’s built-in filter and selection tools.
• Database agnostic.
