SADES (Statewide Asset Data Exchange System) establishes a primary transportation inventory of assets including a maintainable condition assessment process for many state and local agencies. Its unique approach to statewide asset management efficiently utilizes modern technology and joins efforts for the common good of accurate and sustainable data collection.  Even though the Technology Transfer Center has made asset management software packages available for over 25 years, it wasn’t until changes in technology aligned with software advances to make asset data management available and easy to use for any agency. ESRI (a geographic information system company) software, ArcDesktop and ArcOnline, allows anyone with a smart phone or tablet to have access to the asset management database.  

The SADES Advantage:

Sustainability: This data remains stored on a shared server on the “Cloud”. Once it’s collected, the data remains on this server and can be accessed anytime and from anywhere for any analysis purposes.

Efficiency: With the touch of a finger, the user can easily fill in the attributes using the ESRI application where the data is then instantly submitted, or uploaded, to the server on the Cloud. This means no errors due to transfer of data from paper into a computer database. There is no duplication of efforts as no two agencies are collecting the same data. Every agency involved is contributing its own assigned data towards a common goal of having a central database.

Cost effectiveness:  The hardware, currently in the form of iPads, is not only time efficient, compact and portable, but is also making data collection easier and more economical. With the cloud storing this accessible data, redundancy and repetition are eliminated, lowering manpower costs.  And because the cloud has “instantaneous” share-ability, there is no middle step of data entry back in the office.
