Select Locations

Enter single location

In the Type an Exact Location card in the Query panel, enter the Latitude and Longitude coordinates of the point of interest in the respective fields and click the Confirm Location button

When copying coordinates from a 3rd party source, make sure to include the minus sign for negative lat/long values.

If the entered coordinate is outside of the selected geo, an error message will appear at the bottom-left of the screen.

Running multiple points

More commonly, Data Explorer operations are performed for a series of geographical coordinates provided from one or more CSV files. Refer to CSV formats for samples of CSV file formats that can be used with Data Explorer. 

In the Select locations from a CSV file, click on the Browse button.  When the file manager window opens, select the desired CSV file and click on the Upload CSV button. Repeat this operation for importing locations from multiple CSV files. 

Data Explorer accepts a maximum of 10,000 lat/long coordinates. If the CSV file contains more than 10,000 lines it needs to be broken down in multiple smaller files.

If one or more coordinates are outside of the selected geo, an error message appears that there are some points which cannot be queried.

Using Saved Locations

When either individual coordinates or a CSV file is uploaded, the data is saved in the Saved Locations card in the Query panel.  This function enables users to re-run any data that was already uploaded. Selecting one of the saved locations brings the respective file up to select hazard parameters.  

Saved Locations can be edited by clicking on the Pencil icon to the right, or deleted by clicking on the Trash Can icon. 

Uploaded CSV files are persistent across user sessions, they stay available in the Saved Locations section until they are manually deleted.

Analysis Parameters

Years

The point of time (year) in the future to run the analysis for.

Hazards

Precipitation

Flooding caused by heavy rainfall.

Tropical Cyclone Surge

Flooding caused tropical wind system such as hurricanes or typhoons.

Mid-Latitude Cyclone Surge

Flooding caused by storms that do not originate in the tropics (e.g. nor’easters) and other events that push water from the ocean onto the land.

Seasonal High Tide

Flooding caused by high tides that can lead to nuisance flooding. Colloquially these are sometimes called flooding from “King Tides” or “Sunny Day” flooding.

Combined

Statistical combination of the probabilities of each hazard in the flood peril.

Sea Level Rise

Select the sea level rise scenario of interest. The Low scenario assumes a rise of the Global Mean Sea Level (GMSL) of 0.3 meter by the year 2100, Intermediate assumes 1 meter GMSL rise and High a 2 or more meters GMSL rise by 2100. Find more information about the GMSL scenarios in the Sea Level Rise section. 

Probability

The  annual probability of a flood event. Learn more in the Event Probability section. 

At least one item must be checked in each category. 

Run Query

When done with parameters click on the Run Query button.

Queries against a large number of coordinates and/or many parameters set may takes some time. Smaller jobs may complete in less than a minute while a query of 10,000 points and all parameters enabled can take up to 45 minutes.

A job status appears in the Query History card. The following statuses will occur during the query analysis:

• Analyzing: The application has loaded the locations and the query has started to run and first results are streamed to the output table in the UI.  

• Running Query: Application is running the query.

• Blank: After a query goes from “Running Query” to blank, the analysis is complete.

The Parameters card shows the analysis parameters of the highlighted query in the Query History card. If a query is selected (highlighted) which is showing "Analyzing", the Parameters card does not show any values until the highlighted query changes to "Running Query".   

After a job completes, the Download button in the Parameters card turns from gray to blue.
