LA County GIS Day


What is GIS Day?

GIS Day is celebrated nationally as part of National Geography Awareness Week.  Click here for more information.

LA County’s GIS Day is free to attend both for the public and presenters, supported by County departments and funded by the County’s enterprise GIS Program.  We invite you to join us to learn more about how the County, government agencies, private companies, educational institutions, and non-profit organizations use Geographic Information Systems (GIS) in  emergency response, social services and administration to make life better in Los Angeles County.

Since location information is a powerful tool to provide better services to the residents of the County, our theme for GIS Day 2015 is  “Mapping for a Better LA”.

What is GIS?

gisdaybannerGeographic Information Systems (GIS) are powerful software technologies that allow vast amounts of information to be linked to geographic locations.  Using the concept of an “electronic” or digital map, GIS records, stores, and analyzes multiple layers of spatial data and relates this data to locations of interest (e.g., communities, neighborhoods and people that live there).  These layers contain data in the form of points (e.g., addresses, locations, etc.), lines (e.g., streets, highways, etc.), polygons (e.g., areas, political jurisdictions, etc.) and images that can be viewed in various combinations to identify and display underlying spatial relationships.

Who is our audience?

GIS Day is a chance for GIS staff, students, and residents from around the County to share what they are doing with GIS, make connections, and to reach out to the public and to other using GIS technologies.  We invite government  departments, cities, and agnencies, along with colleges, and private vendors to showcase their programs and capabilities to folks who want to learn more.  Our audience varies in its understanding of GIS, so we are looking to illustrate that the use and value of GIS are limited only by imagination.
