The Communications Assets Survey and Mapping (CASM) Tool provides New York Public Safety Officials with a means to gather and analyze communications systems data to identify gaps in interoperability and to improve emergency response communications.

CASM is a web based application that emergency response agencies can use to enter and visually display data about their public safety communications assets and how those assets are used.

Requests for any additional information or request for CASM access for agencies and entities in New York State must be directed to the following contact at DHSES OIEC:
