| Description: | Agreements under Iowa State code, Chapter 28E, specify the terms under which Iowa State and local agencies can work together to provide joint and cooperative services for the purposes of making "efficient use of their powers." Cooperative efforts can include sharing resources such as information technologies or data. IADOT has signed 28E agreements with other State and local agencies, including some for the purposes of sharing data with cities and counties. These agreements are one way in which IADOT obtains local geospatial data, except for imagery, which is obtained through informal sharing. | |
| 2 | Practice: | GIS Project Portal |

| Description: | The GIS Project Portal is a centralized, web-based portal accessible to IADOT staff that provides a standard framework to query, analyze, and visualize geospatial information. The GIS Project Portal enables users to query any of IADOT's spatial information from one place and view it on a single basemap. The Portal does not function as a data warehouse, but as a database-centric, software-neutral environment. Data are still collected and managed by individual data owners in various business units or offices in their own databases across the agency. | |

| Description: | Deployment of load balanced web map servers using ArcGIS Server. This allows DOT employees to develop custom web portals using javascript, flex or Silverlight. The technology allows data stored in Oracle Spatial databases to be produced once and shared many times. | |

| Description: | The GIS Safety, Analysis, Visualization, and Exploration Resource (SAVER) is Iowa DOT's primary traffic safety analysis tool. The main purpose of SAVER is to serve the needs of analysts using Iowa traffic crash data, as well as to provide users with other data (e.g., roadway, rail, river, corporate limits, etc.) vital to the analysis of safety. Additionally, SAVER will read data such as traffic citations, crime incidents, and operating while intoxicated information from the existing National Model/TraCS (Traffic and Criminal) software. The GIS SAVER website allows users to download SAVER Project files as well as operational directories. New users must must contact Iowa DOT to receive data. | |

| 5 | Practice: | I-Sites: An archeological GIS and Database |
| Subject Areas: | Environment Planning | |

| Description: | I-Sites is an Internet Map Server (IMS) application developed at the University of Missouri-Columbia for the Iowa Office of the State archeologist (OSA). The archeological GIS consists of two interlocked resources providing organized information on Iowa's reported archeological sites. This makes the gathering and sharing of archeological information during environmental review an easier, faster, and less expensive endeavor than before. Individuals and organizations can contribute to I-sites success by submitting - for review and potential inclusion - shapefiles on archeological sites in Iowa. | |

| 6 | Practice: | Multi-Level Linear Referencing System |
| Subject Areas: | Asset Management Maintenance Operations Planning | |
| State: | Iowa | |
| Organization: | Iowa DOT | |

| Phone: | (515)-239-1530 | |
| Description: | The multi-level linear referencing system (LRS) integrates disparate roadway data using the data's linear locations as a common link. A linear location is described in terms of a linear referencing method (LRM). Therefore, in order to achieve full data integration and accessibility, the system must have functions available that can dynamically transform a location described in terms of one LRM into another LRM. For example, an event described in reference to a milepoint may be easily transformed to an improvement project station reference. | |

| Description: | A system to track locations of snow plow and compile plow business data such as spread rates, plow statistics, and speed. Over 300 GPS receivers were deployed in 2011/12. This custom system was developed to harvest plow data in 1 minute increments, aggregate data to winter road segments produced with the Iowa linear referencing system (LRS), and see current plow locations and history. Data aggregated to these segments can be linear and overlaid with other data like pavement condition or paint conditions with the datum reference. | |
