10 Guide for Implementing a Geospatially Enabled Enterprise-wide Information Management System (a) map (b) table Figure 3. Visual display of parcel information. access to high-resolution imagery of their houses, they are coming to expect public agencies to have the same capabilities and more as part of their business. Adding GIS to your right- of-way activities provides additional benefits to your information management system, for example: Visualizing the status of parcels during the acquisition process. Maps are easier to understand and more intuitive than tables or lists as shown in Figure 3. Identifying special factors to consider such as hazardous waste sites, historic districts, etc., by overlaying different datasets. Visualizing the surrounding properties and features that could affect the take and valuation. Reviewing the proposed alignment and affected properties for possible savings or problems. Because right-of-way offices are at varying stages in implementing an information management system and in using GIS, three specific scenarios were considered in NCHRP 8-55A for imple- menting a system: 1. An office does not have an information management system or wants to replace an existing one and include geospatial capabilities. 2. An office wants to geospatially enable an existing information management system. 3. An office does not have an information management system but has access to an agency enterprise GIS. This guide considers each of these scenarios and provides information where appropriate to assist you in building or expanding your system. The 8-55A logical model also supports all three of these scenarios and Appendix B explains how to use the model for the selected scenario. How to Use This Implementation Guide This guide provides a generalized process to implement a geospatially enabled information management system for state transportation right-of-way offices. Agencies can implement or enhance a system themselves or in partnership with the private sector. If desired, the 8-55A logical model can be used as a basis for a system following the guide on how to use the model in Appendix B. This implementation guide is organized to provide a rational process to help you achieve commitment, buy-in, and resources over time to achieve short- or long-range implementation
