University Campus Navigation for All - Peak of Data & AI
University Campus Navigation for All - Peak of Data & AISafe Software Navigating around the 1000 acres of UBC Vancouver’s campus may look like a walk in a park, but when you’re a student in a wheelchair trying to find a powered door to the class you’re late for, it is not all that scenic. UBC’s GIS team will share the journey from the original 2003 static map application to the current web application built using FME and the ArcGIS JavaScript API. There were two main goals with this new application: 1. Enable the UBC community to easily interact with and navigate the campus by walking, cycling and accessible means (which include mobility constraints such as steep slopes, stairs, and doors that are not powered). 2. Provide high quality geospatial data that is authoritative and updated using FME to reflect existing conditions on campus including road, sidewalk or building closures for construction. We will cover the unique challenges in creating a navigation application which offers features that Google Maps cannot at the scale of a University campus. Door to door navigation, avoiding stairs and steep slopes, navigating to accessible entrances and up to date construction barriers are some of the features we will discuss.

Building Geospatial Data Warehouse for GIS by GIS with FME
Building Geospatial Data Warehouse for GIS by GIS with FMESafe Software Data warehouses are often considered the backbone of data-driven decision-making. However, traditional implementations can struggle to meet the iterative and dynamic demands of GIS operations, particularly for Iterative Cross-Division Data Integration (ICDI) processes. At WVDOT, we faced this challenge head-on by designing a Geospatial Data Warehouse (GDW) tailored to the needs of GIS. In this talk, we’ll share how WVDOT developed a metadata-driven, SESSI-based (Simplicity, Expandability, Spatiotemporality, Scalability, Inclusivity) GDW that transforms how we manage and leverage spatial data. Key highlights include: - Simplifying data management with a lean schema structure. - Supporting ad hoc source data variations using JSON for flexibility. - Scaling for performance with RDBMS partitioning and materialized views. - Empowering users with FME Flow-based self-service metadata tools.We’ll showcase real-world use cases, such as pavement condition data and LRS-based reporting, and discuss how this approach is elevating GIS as an integrative framework across divisions. Attendees will walk away with actionable insights on designing GIS-centric data systems that combine the best of GIS and data warehouse methodologies.

- 4. Java Pet Store Demo • Originally was an example for Java J2EE • Can be beneficial to study the source • Has payment module stub • Has shipping module stub • Demonstrates pure Java EE (no Spring Framework)
- 5. Java Enterprise Edition Platform • Extends the Java Standard Edition Platform – ORM (Object Relationship Mapping) in the form of JPA (Java Persistency API) – Distributed and multi-tier architectures – EJB support (Enterprise Java Beans) – JMS (Java Messaging Services) – CDI: Contexts and Dependency Injection – JSF: Java Server Faces for front-end UI – Web Services • Modularity • Many application servers which can host JEE apps

- 8. Example JSF
- 9. Three-tier/layer Architecture • Three-tier – Data – Services / Business logic – User Interface • For data access: ORM • For modular architecture and SOA: Dependency Injection • UI layer: often MVC technology, templating engines
- 10. Architecture UI client side UI server side (MVC controllers and models) EJBs Service Oriented Architecture ORM: JPA, Hibernate, iBatis, etc. DB DAO CDI config Configuration UI layer Services / Middle / Business layer Data access layer JDBC Data-base Backing Beans, DTOs
- 11. Common properties • Use of Java EE • Maven: de-facto standard nowadays (Gradle is coming up though) – Declarative make/build system – Suggest best-practice directory hierarchy (see later) – Testing – Deployment – Documentation generation – … everything!
