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.
Importing map layers into Touchstone
Use Map Layer Import to import map layers (custom GIS data) from raster or vector files into Touchstone.
ENVI raster files
Touchstone supports the import of ENVI raster files as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. (You must have a license for 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.

- Business use cases for geospatial analysis
  Here are potential business use cases for geospatial analyses.
- Licensing considerations in geospatial analysis
  We offer great flexibility in how you manage licenses for Touchstone software.
- Overview of creating a new geospatial analysis
- Choosing the analysis type in geospatial analysis
  Choosing the analysis type is the first step in configuring a geospatial analysis.
- Configuring a new geospatial analysis
  Configuring the analysis is the second step in the process.
- Modifying settings and reinsurance
  Step 3 in a geospatial analysis allows you to modify financial reinsurance, and analysis management settings,
- 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.
- Widgets
- 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.
  - Projections
    We have certified the following projections (PRJ). Other projections may also work.
  - Raster files—guidelines and restrictions
    Before importing raster files, consider the guidelines and restrictions specified in this topic.
  - Vector files—guidelines and restrictions
    Before importing vector files, consider the guidelines and restrictions specified in this topic. Each vector feature has attribute data that describes it. For supported geometry types for each vector format, see the Help topic for the format.
  - Shapefiles
    Touchstone and Touchstone Re support various shapefiles. The shapefiles spatially describe geometries such as points, lines, and polygons, which represent geographical features such as the epicenter of an earthquake, hurricane storm tracks, wind speed footprints, and state boundaries.
  - GeoJSON vector files
    Touchstone supports the import of GeoJSON vector files (.json and .geojson) as map layers. You can then visualize your exposure data with the imported map layers and run geospatial analyses with the map layers. (You must have a license for Geospatial Analysis.)
  - GML vector files
    Touchstone supports the import of GML vector files (.gml) as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. (You must have a license for Geospatial Analysis.)
  - SQLite vector files
    Touchstone supports the import of SQLite vector files (.sqlite) as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. (Geospatial Analysis requires a license.)
  - ArcInfo ASCII raster files
    Touchstone supports the import of ArcInfo ASCII raster files (.asc) as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. You must have a Geospatial Analysis license.
  - GeoTiff raster files
    Touchstone supports the import of GeoTiff raster files as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. (You must have a license for Geospatial Analysis.)
  - ERDAS IMG raster files
    Touchstone supports the import of ERDAS IMG raster files as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. (You must have a license for Geospatial Analysis.)
  - ENVI raster files
    Touchstone supports the import of ENVI raster files as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. (You must have a license for Geospatial Analysis.)
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.

ENVI raster files

Touchstone supports the import of ENVI raster files as map layers. You can then visualize your exposure data with the imported map layers and run Geospatial Analyses with the map layers. (You must have a license for Geospatial Analysis.)

You can import files with the following extensions. The ENVI file is sometimes associated with a .prj for projection support.

HDR: Header file
DAT or BIN: The data component file in flat binary format

You can import projected ENVI Raster files.

Support for types of raster cells:


Byte
Complex Int32
Int32
Int16
UInt16
UInt32
Float 32
Float 64
