Imperial Valley Spatial Data Infrastructure Project

Meeting Objectives Redlands Institute: Recap of Project Objectives and Process Review Preliminary GIS Database Review prototype web-based tools Document your feedback Participants: Provide comments on the design, content and end user functionality of the system Possible one-on-one meetings to implement suggested changes

Project Objectives Develop GIS database and tools that support non- point source pollution management in the Imperial Valley Primarily for Sediment TMDL implementation Recognize that the GIS could benefit science/research community as well

Imperial Valley SDI Project Tasks Conduct needs assessment and requirements analysis Develop TMDL Geodatabase Develop TMDL Analysis Tools and Models Conduct orientation seminar Develop Web-based Application Prepare Outreach Materials and Support Future Data Collection and Analysis Techniques Final Reports

What is Spatial Data Infrastructure? SDI as a principle recognizes GIS data as a fundamental infrastructure component for national or regional development SDIs are built around ‘communities’ with a common interest/objective and use the internet to share ‘fundamental’ information and tools Users access SDI resources (GIS databases, models, outreach materials) through a web browser Institutional policies, procedures and standards to manage how information is shared/used is critical to long term success

Anticipated Outcomes More efficient use of existing information Increased use of monitoring and related data for NPS management/research Better data access/quality Standard methods for collecting, formatting and reporting water quality related data Policies and procedures to guide how data is collected, shared and used

Database Design Objectives Create a sediment TMDL geospatial databaseCreate a sediment TMDL geospatial database Improve on the USGS National Hydrography Dataset (NHD) dataImprove on the USGS National Hydrography Dataset (NHD) data Incorporate local data from various agenciesIncorporate local data from various agencies Support better analysis of water quality and land management practicesSupport better analysis of water quality and land management practices Comply with the State Water Resources Control Board (SWRCB) Surface Water Ambient Monitoring Program (SWAMP) standardsComply with the State Water Resources Control Board (SWRCB) Surface Water Ambient Monitoring Program (SWAMP) standards

Sediment TMDL Related Data Total Suspended Solids (TSS), Turbidity, Monitoring locations (R7, IID, BOR) Surface Hydrology Network (NHD, IID) Agricultural Practices (ICFB Farm Reports) Drainsheds, Farm Plots (RI) Land ownership boundaries Owner/operator data (ICTA, IID)

Process of making a database compliant Obtaining the data Obtaining the data Processing the data Processing the data – Coding flow direction, Changing field names and data types so they fit into SWAMP standard fields and data types Crosswalk data from various tables Crosswalk data from various tables Include all required SWAMP tables and fields Include all required SWAMP tables and fields Create links between tables Create links between tables
