When data disagree: Incorporating information from multiple sources into a comprehensive spatial model

Quinn_unSeminar_2018Presented by Quinn Hart (Digital Applications Manager, UC Davis Library)

Tuesday, MAY 8th 2018,
12-1pm @ the DSI ,
Shields Library Room 360


unSeminar Abstract:

Satellite imagery and GIS modelling allow us the power to address complex environmental questions over large regions.  But, what how do we address issues when these data don’t agree with more local sensors?  Can we combine data from multiple sources, with varying resolutions and biases, into a single, comprehensive spatial model? We will discuss a modelling effort being conducted in collaboration with California Irrigation Information Management Information System (CIMIS) program to create new Evapotranspiration maps of California water use zones based on data from the Department of Water Resources (DWR) weather stations and the GOES weather satellite, collected over 13 years. The spatial modelling efforts have led to inconsistencies with some DWR weather stations being assigned to inappropriate zones.  How can we best utilize all of the available data and correct for these mismatches? How will we know if the implemented changes are good ones?

This talk may be of interest to those thinking about data integration, geospatial and modelling errors, evapotranspiration research, and working with DWR and other weather data.

#maptimeDavis Workshop Series

Logo_RainbowThe UC Davis Library’s Data Management Program & UC Davis Center for Spatial Sciences is proud to present #maptimeDavis, a geospatial skills workshop series.

Maptime is quite literally “time for making maps”.  The primary goals of Maptime Davis is to teach skills related to mapping and to provide a forum for the Davis Community to find others with similar interests to facilitate learning.  The series has been scheduled for Mondays 2:00-4:00 in the DSI (Data Science Initiative) Classroom, room 360 Shields Library, unless otherwise noted.

This is the schedule as of 9/18.  Minor changes may occur.

Humanitarian Mapathon

As part of Geography Awareness Week, the Center for Spatial Sciences and UC Davis Mapping Club are hosting a Humanitarian Mapathon on November 17th, 11am-5pm.

The objective of Missing Maps humanitarian mapathons are to map the most vulnerable places in the developing world so that local and international NGOs, communities, and individuals can use the maps and the data to better prepare for and respond to crises affecting the areas.

This mapathon is a great introduction to the OpenStreetMap project and what it means to be a humanitarian mapper. No experience required, all are welcome, snacks and stickers will be provided.
