Utilities commonly make use of several types of facility map products to support operation, planning and analysis activities. These maps may be created at widely differing scales. For example, an operating map is commonly generated at scales of 1":1000' or 1':200', while switching diagrams may be as small as 1":1000'. When the facility data and associated landbase information are converted into a GIS environment, the wide range of output product scale requirements may dictate that multiple versions of the data be captured and maintained. This is particularly true for annotation features.
Populating an ArcInfo-based facilities data model with multiple versions of annotation presents a unique set of challenges to a conversion vendor. This paper will address these issues and discuss methods to maximize efficiency in the feature creation and editing processes. Alternative methods of structuring the data and suggestions for efficient use of ARCEDIT functionality will be highlighted. The relative costs of generating multiple feature representations will also be outlined.
