In-Depth: Snapping Illustrated This Distance is called Snap Tolerance. A Roadway Network User positions puck here. Snapping records Incident here. Snap Tolerance (old way): Preset Fixed Distance. Snap Tolerance (new way): Dynamic based on Map Extent. 06

What Exactly is Dynamic Snap Tolerance? Snap Tolerance is Whatever this Distance is on the current Map Extent. 07

More on ILT GPS Guidance User can move Puck OR GPS can guide the Puck! ILT 5 Auto-Detects GPS Feed on any Serial Port. Technically Speaking: Any Real or Virtual COM Port NMEA Sentences at 4800 8, N, 1 Be Aware: GPS is Subject to Atmospheric Interference. Be Aware: GPS does NOT fit roadway maps perfectly.

Attention Admins: ILT 5 Can Receive Web Updates! Sub-System is called ILT Version Update Server Maintains system code AND mapping via Web Updates. Constant network connectivity is NOT required. ILT software and maps are Version Fingerprinted (Build IDs). Update files are packaged and compressed for transfer. Offline Mode is supported (e.g. via USB or CD). Control is tunneled in HTTP and Data transfer uses FTP. 10
