Ladris pulls basic address & road network data from OpenStreetMap, ESRI, and affiliated entities. While this data is typically up to date, certain jurisdictions may have special evacuation considerations which would affect these datasets. Ladris will need to assist in customizing these for your account. For example, updates to these datasets can be made within the jurisdiction where communities have a number of cars per address above census data or where routes cross private addresses & beach roads that factor into an evacuation scenario.
