Abstract
3D Navigation Using ArcGIS Server with Very Large Data Sets
Track: Technology Integration
Author(s): Alex Ly, Duane Morrison
The U.S. Army Corps of Engineers (USACE) operates and maintains 25,000 miles of navigable channels and 196 commercial lock and dam sites and is responsible for harbors and waterways in 41 states. The USACE’s Topographic Engineering Center publishes Inland Electronic Navigation Chart (IENC) data for over 8500 nautical miles of navigable waterways. Delivering accurate data in a timely fashion is crucial for safe navigation on those waterways. This ArcGIS Server based web map service publicly distributes IENC data (over 17,000 files), leveraging publicly available, high quality satellite imagery and existing 3D visualization tools while allowing mariners to navigate in real time on our Nation’s inland waterways. This application solves the inherent problem of very large data set distribution by implementing data resolution pyramiding and scaling techniques and segmentation schemes upon the complex IENC geodatabase.
