Introduction
Introduction to the Touchstone Re application.
Companies
A company is unique entity in Touchstone Re.
Company data (exposures)
Companies are associated with exposure data.
- Area and subarea
  Touchstone Re supports area (lower resolution) and subarea (higher resolution) resolutions that vary by country and model.
- Exposure sets
  An exposure set is a collection of data with at least one exposure type.
- Maps
  Maps are used to view exposure data in context.
  - Base maps
    The Base Maps tool allows you to assign a base map.
  - Map layers
    The Map Layers tool allows you to manipulate maps.
  - Measure tools
    The Measure Tools allows you to measure distances and areas.
  - Drawing tools
    Use the drawing tools to enhance your map.
  - More about maps
    - Projections
      Verisk has certified the a collection of projections (PRJ).
    - GeoJSON vector files
      Touchstone Re supports import of GeoJSON vector files (.json and .geojson) as map layers.
    - GeoTiff raster file
      Touchstone Re supports import of GeoTiff raster files as map layers.
    - GML vector files
      Touchstone Re supports import of GML vector files (.gml) as map layers.
    - Shapefiles
      A shapefile is a simple, non-topological vector format for storing the geometric location and attribute information of geographic features.
    - SQLite vector files
      Touchstone Re supports import of SQLite vector files (.sqlite) as map layers and multi-table SQLite.
    - Vector files - guidelines and restrictions
      Before importing vector files, consider the guidelines and restrictions in this topic.
- Company loss sets
  Company Loss Sets are one type of company data.
Programs
A program is integral to a company and it's exposure data in Touchstone Re.
Portfolios
A portfolio is a group of treaties selected from across companies.
Import
Import exposure data from external sources into Verisk databases.
Export
Export exposure data, results, reports, and companies out of Touchstone Re.
Loss results
The Loss Results pane for a company lists all loss analyses that have been executed for the company.
Analysis
An analysis in Touchstone Re is a probabilistic analysis of your aggregated loss or exposure data.
Tools
Tools to manage Touchstone Re and its data.
Administration console
The Administration Console enables authorized users to manage a suite of administrative tasks.

Vector files - guidelines and restrictions

Before importing vector files, consider the guidelines and restrictions in this topic.

Each vector feature has attribute data that describes it. For supported geometry types for each format, see the Help topic for the format. You can click the hyperlink for each topic in the File Size table.

Projections

Verisk has certified various projections as described in the Projections topic.

File Size

The following table summarizes file size restrictions:


Format Name	Maximum File Size
ESRI Shapefile	2 GB for each component
GML	No constraints. 1 GB for a 32-bit platform.
GeoJSON	No constraints
SQLite	No constraints

File Naming Conventions

The file name must begin with an alphanumeric character and can contain only alphanumeric characters, underscores, and spaces. For example, Mall_T=0.06 is incorrect, while Malla_T_006 is correct.
The file should not use SQL reserved words as field names. For example the field names should not contain: "merge", "load", "add", etc. Here is the full list of SQL reserved words: http://technet.microsoft.com/en-us/library/ms189822.aspx.

Geometry

Touchstone Re does not support layers with mixed geometry types, for example, points, lines, and polygons in the same file. Make sure that the vector files that you are importing are compatible with the layer type; otherwise, the application may produce an error about incompatible geometry types when you run the analysis.
Touchstone Re supports the import of files with Z and M attributes, but does not use them in processing or visualization.
Touchstone Re can import a spatial data file that contains objects with NULL geometry, but does not use those objects.
