Security
Built for Public-Sector Requirements
Assessment offices answer to taxpayers, boards, and auditors. Every part of M.A.P.S is designed to hold up under that scrutiny.
IAAO Standards Compliance
Every ratio study metric — COD, PRD, PRB, and median ratio — is calculated according to IAAO Standard on Ratio Studies. Results are shown against the published IAAO thresholds.
Encrypted Connections
Every connection to M.A.P.S is served over HTTPS with TLS, and sessions are authenticated with signed tokens.
Zero-Install Architecture
Runs entirely in the browser — no software to install, no IT tickets to file, no updates to manage. Works on any device with a modern web browser, including government-issued machines.
Role-Based Access Control
Workspace-level permissions ensure team members only access the data and pipelines they need. Administrators can manage users, roles, and access across their organization.
Data Handling
Uploads are validated on ingestion and kept in your workspace. You retain ownership of your data.
