ODOT FACS-STIP Asset Web Mapping and Reporting Tools

Working in cooperation with CH2M HILL the Oregon Department of Transportation (ODOT) has created a suite of web-based GIS tools to view, integrate and distribute roadway asset information to agency employees across the state. Access to asset data is a crucial requirement in the process of scoping potential construction projects and performing many other tasks that ODOT employees complete on a daily basis. The users of the application will range from project managers and planners to maintenance field crews and engineers. They all need the most up-to-date information regarding the highway network and its associated assets to perform their duties.

The ODOT FACS-STIP scoping tools created provide a single point of access allowing users statewide to interact with and reference this data. ODOT roadway assets range from signs and guardrails to culverts and sidewalks, as well as the State Highway network itself. To enhance the distribution of this critical information ODOT chose to leverage its existing GIS investment by creating new web-based tools which allow users to interact with and explore the available asset data utilizing an easy to navigation map interface. This tool consists of interactive maps that deliver a high level of control over map navigation and data display. The map itself has gone beyond the traditional display-only mode to allow users to interact with it as a bulletin board, sharing information with one another. The tools also provide comprehensive asset reporting, allowing users to generate reports for asset groups based on a location of interest, eliminating the need to sift through irrelevant information.

The creation of these tools is allowing ODOT to do ‘more with less’ by:

> Investing in the future. By spending the money now on advanced tools for sharing asset information to its users, ODOT is spending less down the road by streamlining work processes and eliminating redundancy.

> Creating modular software. The new software tools may be easily customized by ODOT developers, and the current application may be leveraged in whole or in part by other tools in the future.

> Reducing server processing and meeting performance specifications. The architecture chosen for the development of the tools utilizes the JavaScript API for ESRI’s ArcGIS Server, splitting more of the processing load between server and client, and reducing the need to upgrade hardware.

The Oregon ArcGIS Server Special Interest Group-Thursday’s Lunch Discussion on API’s

The Oregon ArcGIS Server Special Interest Group

The Oregon ArcGIS Server Special Interest Group provides a mechanism for sharing codes, ideas, strategies, and standards for developing interactive maps use the ESRI software, ArcGIS Server.  These applications are developed in Flex/ActionScript, JavaScript, .NET, Java, or Silverlight. Previous applications have been developed in ESRI's software called ArcIMS. Membership is open to anyone. Meetings are mostly held in the Willamette Valley. The Google Group website is:


Thursday’s Lunch Discussion on API’s  (12:00 -1:00- Landmark 1)

Most of the GIS Developers for the interactive mapping systems are fairly new to using these programming languages. Many still are questioning which Application Programming Interface (API) to use. The Thursday lunch will be a round table discussion of the advantages and disadvantages of each API and general discussion of what was learned during the conference week.  GIS Developers from other states are also welcome to participate in this discussion.

A Head Banger’s Viewpoint: Practical Considerations for Implementing ArcGIS Server

Those fortunate enough to implement an ArcGIS Server at the enterprise level, especially one previously based on ArcIMS are in for an interesting challenge. This presentation explores the elasticity of ArcGIS Server performance, the importance and consequences of applying “best practices” in architecting map services, and provides the pros and cons associated with various ADF and API application environments. Taking a “lessons learned” approach, information presented is based on real experiences associated with the implementation of ArcGIS Server and migration of a large scale enterprise GIS from ArcIMS to ArcGIS Server. Rare and little known nuances, those that result in a dented wall, will be shared with the audience as well as ADF and API development experiences. With shrinking budgets and resources it is becoming more important to select the best and most efficient approach or solution that can maximize your data and technology, ultimately make you a more effective organization, and may result in a few less headaches

Working with the ESRI Silverlight API

Latitude Geographics has built web applications using all of the APIs available with ArcGIS Server. This presentation will provide some insight into our experiences, including why Silverlight is the leading API to build lightweight mapping applications with. Latitude Geographics will also present a demonstration of a map-driven Automated Vehicle Locator (AVL) solution using ESRI ArcGIS Server and the Silverlight API.
