Furthering justice with spatial analytics & visualization!

Welcome to the Spatial Analytics and Visualization Institute (SAVI) page, an official SJSU Campus Institute in the California State University system. We are the only CSU Institute in Northern California to implement advanced GISci techniques for justice, equity, and democracy research and education! SAVI uses the power of geography and Geographic Information Science to produce impactful research and professional services with focus on furthering justice, equity, and democracy to serve our university departments, neighborhood organizations, public agencies and private sector entities in Silicon Valley and the Bay Area.



Hosted by SAVI; Urban High-tech Zones and Smart Growth Planning, a gathering of researchers, practioners and policy makers in Silicon Valley

On November 8th at 5:30, SAVI is hosting the Urban High-tech Zones and Smart Growth Planning with two talks, a panel discussion and a book launch event, all focused on cities, high-tech economy, and strategic planning for smart growth! in URBP San Jose Downtown Studion on 76 S 1st St, San Jose, CA 95113. With two talks on the U.S. Urban High-Tech Zones and  Tecnológico de Monterrey Innovation District Plan, SAVI will host a panel discussion with University, Planning, and Policy Leaders in Silicon Valley

SAVI's New Work - San Jose Bike Equity Web Map

SAVI's recent research uses GISc techniques to quantify a bike infrastructure availability score to account for the availability of bike paths as well as the variation of safety and comfort across different bike path classes in San José, California. This score helps to find out where San José's best (bike paradise) and worst (bike desert) regions are for cycling, how different the socioeconomic attributes of San José’s bike desert and paradise residents are and whether San José succeeded in achieving an equitable infrastructure distribution and, if so, to what extent?

Featured Project

Internet Access Map - CA Assembly District 30

This project assessed and visualized broadband availability vis-a-vis the location of those who are in need of broadband access in the Assembly District (AD) 30 communities. In AD 30; according to the Census 2018 estimates, one out of every three people is below 18 years old; who could be a student needing broadband service for the new academic year. A preliminary analysis revealed that the communities with a higher share of vulnerable households in this district are also the areas that have relatively lower broadband access fixed services. This project was done in collaboration with the SJSU Lurie College of Education and resulted in a report and a broadband access web-map which allows users to visualize, overlay and analyze broadband and the location of those who are in need of broadband access. The results of this project enable detailed assessment of the areas that could face connectivity challenges in order to support both public and private sectors, and local communities to work towards closing a digital divide within the AD 30 communities.

Spatial Analytics & Visualization Lab Workshops; Fall 2022

The Spatial Analytics and Visualization Institute (SAVI) is delighted to launch the Fall 2022 spatial analytics and visualization workshop series. These five lab workshops in November offer professionals and students the opportunity to learn innovative and hands-on skill sets in 3-hour lab sessions with expert instructors from private industry and higher education. The skill sets covered in these lab workshops will help professionals to progress in the tech oriented job market and students to advance their data driven projects and knowledge. With the generous support of Public Interest Technology University Network, these workshops are FREE FOR SJSU STUDENTS!

West Coast Drone Mapping

Coastal ecosystems and eelgrass habitats provide important services to the marine environment, including primary production, carbon storage, nutrient cycling, habitat for fisheries species, and erosion control. UASs with high spatial resolution, temporal flexibility, and cost-effectiveness for repeat photogrammetry, afford a significant advancement in other remote sensing approaches for coastal mapping, habitat monitoring, and environmental management. They provide essentially on-demand remote sensing at low cost and with reduced human risk. Drone imagery will be collected at least annually in coordination with in situ samplings which will also be used to validate the imagery by ground-truthing across a range of points within each meadow. Because eelgrass extent in some regions is subtidal and challenging to visualize from the air, we utilize DJI Phantom 4 Pro (RGB) and DJI Inspire (multispectral) drones and related drone mapping technology through Esri Drone2Map. Each year, ideally we allocate 4-6 days at each site for each drone mission to maximize ideal conditions for collecting drone imagery, striving for lowest spring tides, and calm, bright conditions with roughly vertical sunlight.
