I lead two lives - one as an artist and the other as a scientist. More and more I'm finding my two worlds colliding, and it's not the disaster you might expect.

#maptimeDavis – Spatial SQL


When: October 29th, 2018 @ 1:00 – 3:00 pm
Location:  360 Shields Library (DSI Classroom)
Cost:  Totally FREE!
Prerequisite: No experience necessary!
Presenters: Michele Tobias

About: Do you ever wish you could speed up your spatial analysis – just tell the computer to process the data, then sit back, and let it go?  Do you work with big datasets that don’t load well in a graphical GIS like ArcMap or QGIS?  Maybe you’ve got a bunch of shapefiles that need to be combined in a specific way? Well, this is the right place for you. This session will provide background and hands-on experience with geospatial databases. Participants will learn how to import data, manage the spatial columns in a database, and run spatial processes like buffer or clip from a database environment.

#maptimeDavis Mapping Surface Water Change with Google Earth Engine

greatsaltlakeIn this special 3 hour #maptimeDavis session, Ani Ghosh will teach attendees how to use Google Earth Engine for spatial analysis questions related to mapping surface water. Google Earth Engine code editor uses Earth Engine JavaScript API to access various datasets, perform spatial analysis and data visualization in your browser. Prior experience with any programming language (javascript, R, Python… even writing functions for Excel) will be helpful but is not necessary.  This workshop is scheduled to last three hours to allow for plenty of time to learn and try Earth Engine, but participants do not need to stay for the entire session.

When? Tuesday, April 24, 1:00-4:00

Where?  The Data Science Initiative Classroom – Shields Library room 360

#maptimeDavis Field Work Prep

You’ve been through all the equipment catalogs and that one thing you need just isn’t available for purchase.  Whether it’s ground control targets, quadrat frames, or permanent markers, you’re just going to have to make it yourself.  But how?  This installation of #maptimeDavis takes us on a tour of UC Davis’ own Craft Center to learn about the tools and resources available to you AND we’ll get a demonstration of common GPS devices for taking your own GPS points.

When? Tuesday, April 17, 1:00-3:00 – Meet at the Craft Center

#maptimeDavis Is My Research Mappable?




“Is My Research Mappable?” is an introductory workshop on map making and GIS for researchers.

This workshop will introduce GIS and spatial data, include activities for brainstorming with other researchers, and provide resources for getting started working with spatial data.  Examples from medicine, literature, history, and social science!  In this session we won’t be using any specific software, but rather we will focus on discussion & demonstrations.

When? Tuesday, April 10, 1:00-3:00 in the DSI Classroom – room 360 Shields Library

#maptime Davis is brought to you by the UC Davis Library’s Data Management Program & the UC Davis Center for Spatial Sciences with help from several campus clubs and informal learning groups.  Space is generously provided by the Data Science Initiative (DSI).

#maptimeDavis Spatial Databases


Take your GIS skills to the next level with an introduction to Spatial Databases with UC Davis Library’s GIS Data Curator, Michele Tobias!  Writing queries in spatial SQL can save you time and allow you to process much larger datasets than the graphical user interface GIS programs.  If you’re already experienced with programming, spatial SQL can allow you to work with spatial data in new and more efficient ways.  Databases also allow you to organize your data and can circumvent the need for saving many intermediate datasets.

We’ll work with the DB Manager in QGIS for this workshop because it’s easy to install and works on all common operating systems, but we’ll also discuss other spatial database options.

When? Wednesday, March 7th, 2018 from 10:00-12:00 in the DSI Classroom (360 Shields Library).
