Location Insights
Start with Location Insights to get a broadly intersectional perspective of the surrounding area of your assets. We've identified over 200 key metrics best representing a cross-section of our data foundations: Built Environment Foundation, Climate & Hazards Foundation and People & Vulnerabilities Foundation. This perspective provides an organized and easy-to-use catalog of intersectional information.
Review the layers available in Analyst and the available schemas to start working with Location Insights. You can learn more about the specific hazards and scenarios for point and line locations.
Location Insights Layers
Location Insights layers provide a good starting point to familiarize yourself with the area's community, built environment, and hazard exposure to support the most holistic assessments at supported geographies.
These layers reflect the metrics included in the Location Insights schemas, which you can review online or export directly from Analyst.
You can work with Location Insights layers in several ways:
Core Insight – As a Core Insight, your Analyst organization already has default Location Insights layers included in it. You can add these layers to any project. These default options are named Location Insights – Parcel and Location Insights - <census unit>. You can't rename these default layers.
A specified set of locations – You can run a location analysis on any point or line layer in Analyst, which can be created in several ways. In all scenarios, you'll receive layers named:
Location Insights – Parcel - for layer name – parcel that intersects the point or location.
Location Insights - census unit for layer name – for points.
Location Insights - buffered distance for layer name – for buffers.
Location Insights – 50m Segments for layer name – for lines.
Location Insights Lines for layer name – for lines.
Unlike the default layers, you can change their names. You can view the layer information to verify when the analysis was run. These details can be helpful if you need to re-run an analysis and need to differentiate the layers.
Location Insights Schemas
We're providing a copy of the complete Location Insights schemas for reference. Refer to Location Insights Hazard Summary and Location Insights for Lines Hazard Summary for information about the supported hazards and scenarios included in the schemas. When working with data schemas, you can navigate information in them by:
Searching for terms on the page using Command ⌘+F (Mac) or Ctrl+F (Windows).
Clicking in the schema window and then copying and pasting the content into a spreadsheet application to look at the details more closely.
Point Locations
When working with point locations, you have schemas available for census and parcel geographies.
Census Schema
See Supported Geographies to verify the geographies included in this schema.
Parcel Schema
Line Locations
When working with line locations, you have schemas available for the line, 50m segments, and the parcels that intersect with the lines (which is the same parcel schema returned for point locations).
Line Schema
Line-Segment Schema
Location Insights Hazard Summary
Location Insights – Hazard Values and Aggregation Exposures summarizes the hazard exposures for Location Insights at the parcel and aggregation levels from Base Canvas: land area, total population, and total value. See Supported Geographies for a complete list of aggregation levels.
The Location Insights layers and schemas include these hazard metrics.

Annual frequency of tropical cyclones in or exceeding each category for the current (1980-2017) and median future (2015-2050) scenarios:
| Percent exposure to hurricane winds at or exceeding Category 1 and 3 storms every 100 years for the current (1980-2017) and median future (2015-2050) scenarios. | |
Probabilities that a location will experience tornado winds of magnitudes of EF 0 and greater and EF3 and greater. | Percent exposure to EF0 and EF3 tornado winds with greater than 0.0001 probability. | |
Estimated wind speed (mph) at 50-year mean return intervals (MRI). | Percent exposure to damaging (noncyclonic) winds of 75 mph or greater at 50-year return intervals. | |
2% chance of peak ground acceleration (PGA) exceedance in 50 years. | Percent exposure to moderate or higher PGA (equal to or greater than 16%g)) at a 2% probability of exceedance in 50 years. |
Location Insights for Lines Hazard Summary
When returning Location Insights for lines after connecting your lines to Insights, we provide hazard metrics for the lines and 50-meter line segments. When calculating metrics for lines, we also generate line segments spaced 50 meters apart along the line. Then, we intersect each line segment with each hazard data layer to determine which hazards and severity levels are present at that segment. To estimate the percentage of the line segment exposed to a specific hazard severity level, we divide the exposed segment by the total length of the line.
Location Insights for Lines – Hazard Values and Aggregation Exposures summarizes the hazard exposures we provide for line segments (50-meter segments) and the aggregation level summaries we provide for the lines. The Location Insights layers and schemas include these hazard metrics.
Hazard | Line Segment Exposure | Line Exposure |
|---|---|---|

Indication of the FEMA flood zone value. | Percent exposure to 100-year FEMA floodplain. | |
