Enterprise GIS and Network Modeling

Modeling Networks is essential for managing them

Applications of Networks in GIS range from roads, storm drains, water or fuel pipelines, to electrical transmission lines, telecommunications system, and beyond. Being able to easily ask sophisticated questions about your network, or quickly identify problem or bottlenecks is essential for high performance and mitigating costs.

Farallon specializes in rapidly and accurately creating network data models, linear reference systems, and dynamic segmentation to support network analysis.

Network GIS Fuel Pipelines Web interface that tracks 1000s of miles of railroad and pipeline GIS data, and millions of street segments nation wide to facilitate locating a leak and executing response.

Using LSR with Network GIS to ask critical questions

Which pipes will no longer flow if we close a valve?

Point and paths in a Network are typically identified using a system of linear references. For example, the location of a leak in a pipeline is referenced by location to known locations of valves or bends in the pipe. A GIS using linear references for the Network model, can answer sophisticated questions, such as "what is the shortest path between point A and B?" or "which pipes will no longer flow if valve X is closed?"

Network GIS Transmission Lines Web-based GIS application that integrates with real-time energy operating databases and allows users to plot transmission maps on the fly

Integrate relevant non-spatial data with an easily understood Network spatial display

Using Dynamic Segmentation, tabular data can be visualized on a map and displayed, queried and analyzed in a GIS. Dynamic segmentation, used in conjunction with a linear reference system, can quickly create maps showing subsets of a network such as a map displaying only the sections of 2 lane roads with pavement rated as "poor".

In addition, we integrate network GIS with industry leading applications such AutoCAD and MTC's StreetSaver Pavement Management System.
