Interactive Emergency Mapping: Using Open-Source and Hard-to-Find Data for Real-World Scenarios
Monday, April 14, 2025 - 1:00 - 5:00 PM


The goal of this workshop is to share knowledge about open-source and secure datasets that could be beneficial throughout the emergency management lifecycle. We will briefly go over the stages of emergency management (i.e., preparation, planning, response, recovery and mitigation) along with examples of real-life GIS applications from Solano County and Dewberry. Next, we will delve into the world of locating open-source data from local, state, and federal data repositories and, for public agencies, how to coordinate with private entities for secure data on critical infrastructure and those with access and functional needs. Lastly, this workshop will end with 2-3 emergency hands-on scenarios where attendees will work together as a team to determine what GIS data and applications they might want to have in a given scenario along with a few injects to “shake things up” along the way.

Disclaimer: Please note that this workshop is not in anyway sponsored nor approved by the California Office of Emergency Services (CalOES) nor the California Specialized Training Institute (CSTI) for the California Office of Emergency Services' Emergency Operations Center credentialing program.

Mapping for Impact: How Counties Use GIS to Solve Critical Community Challenges
Wednesday April 16, 2025 10:30am - 12:00pm PDT
This session showcases the powerful role of GIS to solve county problems such as mental health accessibility, food insecurity, wastewater infrastructure, and public safety concerns. The Los Angeles County Department of Mental Health uses GIS to optimize service accessibility and decision-making, while a food access study in Riverside County highlights disparities in proximity to essential resources. Additionally, a Sonoma County wastewater study maps septic systems to identify sustainable treatment solutions. Lastly, learn how leveraging modern GIS can help propel your community forward as local efforts have pushed government capabilities and resources to extremes. Attendees will gain insights into geospatial applications that drive public health equity and environmental sustainability.

Interactive Mapping for All: Leveraging OpenAI API to Build Accessible GIS Solutions
Wednesday April 16, 2025 10:30am - 12:00pm PDT
In this mini workshop, attendees will use OpenAI API to summarize property data (reviews, area scores, nearby attractions) and present it on an interactive map for easy decision-making.
We will highlight a use case as AI transforms complex property data into concise, user-friendly summaries and display summarized information as clickable markers on an interactive map.

How It Works
  1. Data Collection: Pull property details (address, reviews, area scores, attractions) from public rental databases.
  2. AI Summarization: Use OpenAI API to generate concise summaries of reviews, area scores, and nearby amenities.
  3. Interactive Map: Display properties as markers with AI-generated summaries in popups.
  4. Live Demo Workflow

Attendees may bring a laptop to follow along.

Modernizing Hydrography Channel Extraction
Wednesday April 16, 2025 10:30am - 12:00pm PDT
Now that we have LiDAR data, let’s put it to work improving our surface water maps.  Learn about tools available now for extracting information from the LiDAR digital elevation models, including geomorphic landforms, z-values, and more, to create channels that represent the presence and flow of water on the landscape.  Attendees who provide their own laptop and ArcGIS Pro license will be invited to follow along this demonstration of using a Geomorphic Index (GMI) to help identify the most likely flow paths. This workshop includes fundamentals on the US Geological Survey’s National Map hydrography datasets: past, current, and future; from the NHD to 3DHP, and the role of federal, state, regional, and local entities in building out a modern hydro network for the Nation.

Key takeaways: Our collective investment in LiDAR is paying off by enabling the creation of hydrography that has improved horizontal accuracy and alignment with the earth’s surface. While the USGS has taken the lead in the acquisition of elevation-derived hydrography for its nation-wide 3D Hydrography Program, the build-out of this hydrography network will take several years. In the meantime, GIS practitioners can replace legacy datasets for their own geographies of interest with LiDAR data and tools that may already be available to them. This hydrography can be put to good use for their mapping and modeling needs.

Attendees should bring their own charged laptop and ArcGIS Pro license in order to follow along.

Closing Panel: Sharing Geographic Data in California
Wednesday April 16, 2025 1:30pm - 3:30pm PDT
Sharing geographic datasets is a hallmark of the state’s geospatial community. With improved coordination between a dataset’s stewards, clearing houses to consolidate datasets, and those that use the data, our state’s collective efficiency with all location-based efforts should improve.

A moderated panel discussion with geospatial community leaders, along with audience open discussion, can shed light on the challenges the community has publishing, finding, and consuming authoritative datasets.

Discussion topics may include:
  • The role of geodata portals in the state, e.g. California Geoportal and Esri’s Living Atlas
  • Use of AI tools to gather and process geospatial datasets from disparate sources
  • Defining and recognizing authoritative data sources
  • More efficient methods to consume published datasets
  • Data collaboration and sharing
  • Metadata standardization
