#maptimeDavis Collecting Location Data with Phones and Tablets

When? Tuesday, May 15, 1:00-3:00 in the DSI Classroom – room 360 Shields Library

Anywhere you go, you can be a sensor and collect all sorts of useful geographic data. We’ll cover a variety of options, how to use them and how to extract data, including:

  • GPS Tracking
  • Field maps
  • GeoTagging Photos
  • Field Forms with location
  • Geographic Annotations

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 Learn to High Performance Compute: Geo Style

maptime-hpc

Have you been doing geospatial processes that takes hours, days, or weeks to run? Been wondering if there’s an easy way to make it go faster?

Come learn some ways to take your toolbox to the next level with High Performance Computing (HPC). We’ll discuss and walk-through some examples of taking a iterative processes and turning them into parallel processes that can leverage more power from a single computers or multiple computers (clusters).

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

DigitalGlobe Foundation to Provide Free Access to Satellite Imagery for UC Davis

The University of California, Davis recently entered into a partnership with the DigitalGlobe Foundation, which will enable campus affiliates to freely access high-resolution satellite images from DigitalGlobe, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.) (NYSE: MAXR; TSX: MAXR), for research and educational purposes. Through this collaboration, the DigitalGlobe Foundation will provide sub-meter spatial resolution geospatial data to support the University’s research. The Foundation’s aim is to foster innovative solutions to today’s most pressing challenges, including climate change, food and water security, building resilient cities, and recovery from large-scale natural disasters.

“This type of data is what we often see after disasters like earthquakes, tornadoes, and severe storms, but the actual range of use of the imagery to help answer ecological and agricultural questions is much wider,” said Susan Ustin, Professor of Environmental and Resource Sciences in the Department of Land, Air and Water Resources.

DigitalGlobe imagery has been used to support groundbreaking research on measuring the effects of climate change on the landscape, understanding animal populations and biodiversity, identifying undiscovered archeological sites, and determining how to best provide humanitarian assistance and disaster relief.
