Geospatial analysis
Geospatial analysis enables you to perform a deterministic risk analysis with your own view of risk on accumulations of property exposures and workers' compensation information in given areas exposed to natural and man-made catastrophes.
Choosing the analysis type in geospatial analysis
Choosing the analysis type is the first step in configuring a geospatial analysis.

Using Touchstone online Help
You can access the top-level or context-sensitive Touchstone online help from within the application or from the Client Portal. You can then search for content, bookmark pages, and generate output to other formats.
Import data from external sources
You can import exposure data, map layers, projects, and reinsurance packages from external sources into Touchstone databases.
Projects and exposure views
Projects are a useful way to organize your data. They contain exposure views that contain the data that you want to focus on.

- Running the analysis
  This is an overview of running a geospatial analysis.
- Creating and Saving Geospatial Analysis Templates
- Viewing geospatial analysis results
  The analysis results and the spatial analysis functions that you can perform depend on the analysis configuration.
- Display modes in geospatial analysis results
  There are two display modes—Accumulation Display mode and Interactive Browser mode. You can switch between the two modes.
- Spatial analysis options
  There are various spatial analysis options available to use on the analysis results, including the use of widgets to filter all the results that are visible on the screen into a chart or table.
- Filtering widgets by shape
  In Interactive Browser results mode, you can filter chart and table widgets by one or more shapes. Drawing tools, which are available only when you license Geospatial Analysis, enable you to draw shapes, save them, and use them on Touchstone maps.
- Using map layers in geospatial analysis results
  You can display AIR-provided layers or user-created layers on geospatial analysis results. You can also create different tables and charts using widgets. Geospatial Analysis requires a license.

- Maps in geospatial analysis
  Maps are available in many locations in Touchstone.
- Map tools
  Map tools appear along the right side of the map.
- Working with web map layers in Touchstone
  You can import web map layers into Touchstone using various web map servers. This allows users in the same business unit to visualize the web map layers on any map in Touchstone.
- Importing map layers into Touchstone
  Use Map Layer Import to import map layers (custom GIS data) from raster or vector files into Touchstone.
Exposure data validation
Verisk provides a reference containing information about Touchstone exposure data.
Data Quality analysis
The most effective way to assess and enhance portfolio-level or contract-level catastrophe exposure data is to use Touchstone's Data Quality diagnostics. These diagnostics enable you to determine the strengths and weaknesses of the exposure data you are using for analyses and supplement that data when it is missing or weak.
Hazard analysis
Hazard analysis enable you to identify the relevant catastrophe hazards for locations in your exposure data.
About loss analyses
Touchstone enables you to model catastrophic (CAT) events to estimate property and workers' compensation losses.
Reinsurance
The Reinsurance Program Manager enables you to create, import, and manage reinsurance programs.
Touchstone data export types
Touchstone enables you to export different types of data.
Activity Monitor
The Activity Monitor displays the status of all activities.
Managing data sources
Use Data Source Management to manage Touchstone databases.
User model management
Use User Model Management to build custom non-Verisk models and seamlessly integrate them into Touchstone.

Choosing the analysis type in geospatial analysis

Choosing the analysis type is the first step in configuring a geospatial analysis.

In the New Geospatial Analysis pane, after selecting the analysis target or targets, click Step 1 - Choose Analysis Type. A pane opens where you select:


Type	Options
Exposure type	Property, Workers' Compensation, or both Property and Workers' Compensation.
Analysis type	Select one of four types of accumulation or select intersections with GIS hazard layers. The exposure type that you choose determines your choices in this step and in subsequent steps. The Property exposure type allows you to accumulate by zonal accumulations , ring accumulations , event accumulations, and custom boundaries. While configuring the accumulations, you can integrate Touchstone or custom hazard layers and one set of location-level or location summary-level loss results; to do this, you configure intersections. The Hazards and Intersections type allows you to aggregate total replacement value (TRV) based on GIS hazard layers or with loss results. This option does not send the locations to the financial engine for application of financial terms and limits (as it does for the accumulation types of exposures). The Workers' Compensation type allows you to accumulate only by rings. You cannot integrate hazard layers or loss results when you configure the accumulations. When you select both Property and Workers' Compensation, the only available analysis type is Ring Accumulation.
