Announcing the Winners of the 2025 My California GIS Mapping Showcase and Competition

California students used Geographic Information Systems (GIS) to address complex issues affecting the state

The California Geographic Alliance is proud to share the work of incredible students from across the state who are the recipient of awards for their submissions to this ninth annual iteration of this competition. The competition encourages middle (4th-8th grade) and high school (9th-12th grade) students to harness the power of Geographic Information Systems. Students choose an issue, story, or event within the state to examine in depth. They use ArcGIS Online to access geographic data and analysis tools and then produce a StoryMap that shares their results and insights. 

The competition is coordinated by Dr. Waverly Ray, Professor of Geography at San Diego Mesa College. Dr. Ming-Hsiang Tsou, Professor of Geography at San Diego State University serves as head judge for the competition.

9th-12th Grade Division

The selection of a winning project was exceedingly difficult this year. Awards are being presented to five outstanding projects, and at least one member of our panel of four judges gave three different projects the highest score. Each project was thoughtful, highly relevant, and well-executed. Congratulations to all the students and their teachers and support networks. Each student will receive a certificate from the CGA and a cash award of $50.

A special thank you goes out to the educators who get students in elementary and middle school working with GIS and conducting geographic inquiries. These students will have many years ahead to explore what they learned while completing their projects. In an interesting geographic coincidence, this year’s entries from the younger students tended to come from further north in the state than the entries in the higher grades. Way to go NorCal youth!

Explore Data About Your Place in the World Using Geography and GIS

Get to know your community better. Studying the people and the environment in the place where you live has numerous benefits.

  • A local scale inquiry builds on experience and insights that you are already accumulating through your everyday lived experiences.
  • You can take advantage of opportunities for experiential learning and develop your skills through direct observation and interaction.
  • You can connect learning to civic action and find ways to contribute to your community based on what you are learning.

These are two tools designed to help you access, collect, and learn from information about your local area. These can help you better understand the place where you live and study. They can also help you find ways to connect with and contribute to your community.

Environmental Justice for California Communities: An Interdisciplinary Workshop Series for Secondary Teachers

This is an exciting Professional Learning program presented by the California Environmental Literacy Initiative, several California Subject Matter Projects, and the California Geographic Alliance. We are excited to support a cohort of teachers to become leaders in using an exciting new resource for place-based environmental learning and action.

In the 3-part series, teachers will get experience with classroom-ready resources and will learn how they and their students can use geospatial tools to develop their own inquiries. The CHELA (California’s Hub for Environmental Learning and Action) website helps educators, students, and collaborators:

  • use powerful GIS mapping tools to access current data and visualize, understand, and analyze important issues in a way that centers their own communities and concerns, wherever in the state they may live;
  • follow their interests and hone their own questions across a broad range of topics related to the environment, sustainability, and environmental justice; and
  • share their stories of environmental learning, action, and advocacy.

Celebrate California Biodiversity Day by Documenting Biodiversity in Your Spaces, Sept. 4-12

To recognize California Biodiversity Day , the California Geographic Alliance is organizing students across the state to become Biodiversity Explorers and Mappers. In the interest of developing environmental literacy and stewardship in all young people, this will be an opportunity for close observation and appreciation of the amazing diversity of organisms present in our state, which is a global biodiversity hotspot.

Encountering California Biodiversity Close to Home

California has pledged to make all students environmentally and climate change literate. Outdoor education, fieldwork, and deeper connections with place need to be built into K-12 education to make that happen.

As part of this year’s recognition of California Biodiversity Day (September 7, 2020), the California Geographic Alliance is organizing students across the state to become Biodiversity Explorers and Mappers. In the interest of developing environmental literacy and stewardship in all young people, this will be an opportunity for close observation and appreciation of the amazing diversity of organisms present in our state, which is a global biodiversity hotspot. Using the citizen science platform iNaturalist, students will document plants, animals, insects, and other organisms that they observe in their yards, school grounds, or local parks and open spaces. In addition to the individual observations contributing to science, the collective efforts of students will be shared in a unique map using online mapping software (ArcGIS Online) that is freely available to all schools.

Optional informational webinar on 9/3 at 3:45 p.m.

Teaching with Geospatial Technology

Since 2017, the CGA has enjoyed an excellent partnership with Dr. Katsuhiko Oda of the Spatial Sciences Institute at University of Southern California.  Dr. Oda has been successful is securing funds to support research on the effectiveness of professional development focused on geospatial technology, and this creates opportunities to provide high quality professional development to California’s teachers.  CGA’s experience providing PD matches perfectly with Dr. Oda’s research and teaching interests.  Work carried out during the 2017-18 school year was presented at the GIS-Pro / CalGIS Conference in Fall 2018.  This year, a grant from Esri, the world’s leading provider of GIS software, provided support for further work.
