Network Editing and Management Software

The Vendor is required to provide an upgrade to the tools software package, an ArcGIS add-in that is used by the staff of the council planning board to manage and edit transportation networks used by the council regional travel demand forecasting model.
- End of ArcGIS 10.8 Support: ArcGIS 10.8 has already reached the end of general support (March 2024) and will reach the end of extended support in a year (March 2026).
- Security and Compliance Risks: Without official Esri support, the tools application may become vulnerable to security threats and will not receive updates or patches.
- Limited Integration with Modern GIS Systems: ArcGIS 10.8 relies on COM-based ArcObjects, which is now outdated and incompatible with Esri’s future GIS architecture.
- Contractor will migrate tools to the ArcGIS pro platform, which is a 64-bit GIS application designed as a replacement for the older 32-bit ArcMap (part of ArcGIS 10.x) utility, offering a modern user interface, 2d/3d mapping capabilities, and enhanced performance.
- The 64-bit ArcGIS Pro software does not support Microsoft Access Database (.mdb), which is based on 32-bit technology. As such, as part of the migration to ArcGIS Pro, the network database must be transitioned to a compatible format.
- Microsoft Access Database to SQLite:
•    Lightweight and Portable: Unlike File Geodatabases, SQLite databases are a single file, making these files easier to share.
•    Cross-Platform: Works with both ArcGIS Pro and non-Esri applications.
•    SQL Query Support: Unlike File Geodatabases, SQLite allows for standard SQL queries.
•    Good for Governments Model network: If a full Enterprise Geodatabase is unnecessary, SQLite is a good lightweight alternative.
- It should also enable users to retrieve transit data for any specific year or period, thereby significantly speeding up network development for planning activities that involve multiple analysis years, such as the air quality conformity analysis of long-range transportation plans.
- The current transit network maintains separate records for individual analysis years, which results in redundant data storage and makes a temporal analysis challenging.
- To overcome this shortcoming, contractor will convert the individual year-specific transit networks into a unified, continuous transit network by introducing two key attributes: "start year" and "end year."
- The contractor will implement the conversion to the any-year transit network and make necessary adjustments in tools to make sure that the any-year transit network works seamlessly with the existing highway/transit network editing functionality.
- Modern Language Features
•    LINQ (Language Integrated Query): Powerful querying capabilities directly within the language.
•    Async/Await: Allows asynchronous programming, which is crucial for improving the responsiveness and performance of applications, especially for geospatial applications that may involve long-running operations.
•    Pattern Matching: Simplifies complex decision-making logic, making the code more readable and maintainable.
•    Tuples, Records, and More: C# supports several modern features like records (for immutable data types) and tuples, which make the code cleaner and more concise.

- Contract Period/Term: 1 year
- Questions/Inquires Deadline: August 22, 2025
