[Geospatial] REMINDER: Geospatial/GIS meetup tomorrow, February 9 - Rivera Library 140 and Zoom

[Janet Reyes]

Hello everyone,
Our Geospatial/GIS meetup for February will be held tomorrow, Thursday, February 9 from 12:00* - 12:50 pm PST, on Zoom and in Rivera Library, Room 140.
*NOTE: because the room will be occupied until just before noon, we might have to start a few minutes past the hour.

Our presenter will be Richard Minnich, Professor of Geography in UCR's Earth and Planetary Sciences department. Dr. Minnich will present on Tree Atlas of the Californias, compiled using Google Earth.

This atlas is a compilation of unprecedented high resolution maps of 87 tree species in the three Californias along the North American Pacific coast-California south of San Francisco, Baja California, and Baja California Sur-interpreted from Google EarthTM imagery. Google Earth is a transformative platform for broad scale ecological research. It permits the viewing of vegetation at high resolution both at large scales for broad spatial pattern, and local scales for taxonomy, population characteristics, and map accuracy. Using the history function one can observe vegetation dynamically on georeferenced time-series imagery including growth, recruitment, mortality, vegetation response to disturbance, and long term vegetation dynamics.

In the mapping process, imagery is analyzed one species at a time. While this requires multiple scans of the study area, species by species, the eye automatically captures "surprises" subliminally and this led to discovery of 31 species range extensions not reported in previous surveys or in botanical collections. The species approach permits the analysis of single taxa and deconstruction of a priori defined plant assemblages. The kml/kmz software gives capability to separate maps of species as independent files that can be aggregated into plant communities in a geographic information system (GIS).

Implications of the outcomes of this mapping project will be discussed.


We'll start with a few announcements prior to the presentation.
Feel free to forward this email to anyone who might be interested.

The meetup will be recorded.
