The Nearmap ImpactAssessment AI product comprises a selection of Gen 5 AI layer vectors, bundled in a special pack, is now available for ImpactResponse. With this layer data, you can perform a preliminary assessment of damages caused by a catastrophic event to plan the appropriate response.
You can access assessment data in ImpactAssessment AI via the APIs if you have a subscription for both the Nearmap ImpactResponse (Disaster Coverage) and Transactional Content API products.
You can access ImpactAssessment AI using the Transactional Content API.

NOTE: We recommend that you cross-check the results from this with MapBrowser imagery or imagery from another source. For more information, see https://help.nearmap.com/kb/articles/874-statistical-performance.

Generating the transaction token
To generate the transaction token, provide the following information.
address or poly
Complete address of the parcel including the country. For example, 333 Guadalupe st, Austin, TX 78701, USA. Note that you can specify this in any case.
The polygon for which you want to retrieve surveys. The polygon is specified by a set of latitude and longitude pairs, where the first and the last points must be the same.
This can take the value US or AU. This is not case sensitive, and is only valid for an address.
Set this to "single", which is the only acceptable value for this parameter. This uses the latest survey as a default.
since and until
Use these optional parameters to specify a date range to access historical surveys. Specify the dates in the format YYYY-MM-DD. For example, since=2010-01-01&until=2012-01-01 will return the latest survey in this date range while since=2010-01-01&until=2010-01-01 will return a survey on that specific date.
Set this to aiImpactAssessment:postcat.
