 Webinar #7 Speakers:

Nate Roth will be providing a "teaser" for the his presentation at CalGIS on the progress of a project funded by the California Strategic Growth Council (SGC) to collect and standardize parcel data for the entire state.

Nathaniel (Nate) Roth is a staff GIS Programmer and Project Manager with the Information Center for the Environment at UC Davis. He has fifteen years of experience working with GIS data analysis, standardization, and spatial modeling.  His primary interests lie in the use of data and modeling to better inform land use policy formulation. In particular he has focused on the role that land use policy plays in influencing travel behavior, and the impacts of land conversion on agricultural and natural systems. In addition to his staff position, Nate is also a Ph.D. candidate in the Geography Graduate Group at UC Davis 

Mark Greninger will discuss the history of GIS collaboration within Los Angeles County, focusing on the LA County Data Portal, LARIAC imagery consortium, and how the Assessor’s change of heart on sharing parcel information has benefited the County. 

Mark Greninger is the Geographic Information Officer (GIO) for the County of Los Angeles.  He graduated from Stanford University in 1996 with a degree in Environmental Geology, but quickly became passionate about GIS and has been in the field since then, starting with command line Arc/Info.  He began his GIS career by building an Enterprise GIS System for the Environmental Protection Agency in San Francisco.  After the EPA, he moved to Los Angeles County, where he has been for over 10 years. 

He is the County's first GIO, a position he has held for the past 5 years.  As GIO, he oversees the development, governance, and activities of the County Enterprise GIS Program and Enterprise GIS infrastructure.  He leads collaborative efforts with other jurisdictions to acquire region-wide datasets, and develop standards recommendations for adoption and implementation, in order to ensure the deployment and effective use of geography and geospatial technologies for the County’s 100,000 employees and 10 million residents.

Emilio Solano  from the LA County Assessor will discuss how GIS is used in the Assessor’s office to maintain the parcel database, map the location of property boundaries, support appraisal and assessment, including a demonstration of GIS applications used by the Assessor.

Emilio Solano is the Chief Cadastral Engineer for the County of Los Angeles.  He has been working at the Office of the Assessor for 30 years, the last 12 years managing the Mapping & GIS Services Section. In 1986 introduced computer assisted drafting to his section, in 1992 started the implementation of GIS, and by the year 2000 deployed the first GIS application at the Assessor’s website: the Property Assessment Information System, which is still in use. With a total staff of 42 engineers and clerical support, the section manages a geodatabase containing more than 2.4 million parcels, maintains over 117,000 assessor map pages and processes 25,000 parcel changes per year.
