Modules cont'd...
The Sault Ste. Marie Integrated Geomatics System (IGS) municipal / utility solution is built using modules that can act stand-alone or interface together to produce an integrated geomatics environment for local governments and utilities organizations. The IGS modules are presented below. The IGS operates on ESRI ArcGIS 9 suite of products. Each module is based on a UML model, that together comprise the complete scope of GIS Municipal and Utilities management.
Models
The IGS database (Geodatabase) is designed to enforce all critical aspects of spatial data management: data integrity, redundancy, quality, security and ownership.
All IGS models are designed to be as specific as possible while staying generic enough to be implemented anywhere in the world. This challenging balance has been achieved by working with experts in each field of application (mapping, municipal managers and engineers, transportation experts, water and waste water engineers, electrical engineers, and telecommunication engineers) to produce models that integrate all needed concepts, best practices and engineering rules.
All data sets are built using UML (Unified Modeling Language) models that include all definitions but also all behaviors that allow for turning geographic data into self-containing object features. As an example, a water main pipe feature “knows” to what other types of feature it can be connected to (connectivity) and how many of them it can connect to (cardinality). The same water main pipe feature also “knows” how to “behave” when it gets created, deleted, split or merged. Each model also has a complete set of domain values for technical attributes, symbols for each feature and printing templates.
Each feature in a model is made of four (4) distinct types of information. First, the geographic representation of the feature (point, line, polygon) and its symbology (symbol, color, style, scale of representation, etc.); second, the attributes that describe the feature (description, type, status, and other characteristics); third, the metadata that informs about the nature of the feature (capture method, accuracy, date of capture, etc); and, finally, complementary information attached to the feature (hyperlinks). These special attributes (hyperlinks) can be any form of multimedia document attached to a feature to complete its description: scanned documents, digital photos, engineering drawings, word processor documents, spreadsheets, sound tracks, videos, etc. The “Hyperlink” capability is discussed in more detail in the “Application” section of this document.
The different models included in the IGS are presented below:
