11 Consideration for Collaborative Planning Planning Considerations Avoiding Paralysis by Analysis Shared Purpose Goal & Objective Clear Roles & Responsibilities Communication of Process & Information GIS Considerations What do we have or know? What do we need? What s the priority? Did we look everywhere or are there data gaps we need to consider? Communication of Process & Information

12 Ala Wai GIS Goals & Objectives Provide & Enhance Collaborative Team Abilities. Sustainable Solution with Long-term Potential. Utilize Publicly Available Data. Accessible Online through Local & Regional ArcGIS Services. Maintain SDSFIE Compliant Project Data Geodatabase. Build Solution that Utilizes ArcGIS Server Technology.

14 Ala Wai GIS Challenges Maintain Data Integrity & Continuity. Establishing USACE Infrastructure & Technical Certification Requirements. Out-of-the-box Solution with Little to No Initial Customization. Creating Feature Classes from Data not Traditionally thought of Spatially. Wide Audience of Potential Users with Broad Range of Technical & Scientific Savvy. Source Data is in Multiple Formats, Projections, Completeness, Vintages, etc.

15 What s Next? Sort out the GIS Infrastructure Requirements. Create Proof-of-concept Site. Continue Data Preparation, Consolidation, and Organization. Complete Stream Inventory Data Collection. Create Consistent Repeatable Processes to Move Forward.

16 Wish List Create Customization of Site to Include Modeling Capabilities. Develop an Application that Supports Data Sharing, Education, & Knowledge Transfer. Ensure the Solution is SUSTAINABLE and RESILIANT Long-term.
