Living Landscapes: Unhoused Dwelling in Los Angeles Park Space

Analysis conducted via Jupyter and publicly accessible on GitHub takes a new approach to documenting and analyzing tension between housed and unhoused neighbors in Los Angeles, by mapping "encampment reports" in the city from 2015-2020. With a special attention to park-based encampments, many of which have been enclosed and evicted since the initial study period, this research provides a template for further mapping studies through GIS or Jupyter/Python analysis, presented as an ArcGIS storymap.

Does Sacramento exhibit an Urban Oasis Effect?

The urban oasis effect, characterized by cooler temperatures in a city compared to surrounding areas, has been documented in the western United States. To determine whether Sacramento experiences this effect, we calculated land surface temperature for the city and surrounding grassland and agricultural land using MODIS. We compared temperature among these three...

Tips for getting started with the Census API

Learn how to obtain demographic data using the Census Bureaus' data API. We'll start off with an overview of the key decisions you'll need to make: (1) What product: Decennial Census or the American Community Survey, and more (2) Geography: Nation, State, County, Tract, and more (3) Variables: Population, Income, Race/Ethnicity, and more We will then describe the ways you can access the data and how to formulate an API call. See how simple API calls can be once you understand their format. Examples and discussion will be used to clarify questions. Lastly, we will wrap it up with some helpful tips and tricks.

Access Census 2020 data with ArcGIS

New decade, new data, and unprecedented times. The US decennial Census, taken in 2020, counts every person in the US once, only once, and in the right place even during a pandemic. Because census data are inherently spatial, Esri is committed to bringing this data to the community...

Mapping Gentrification in Washington, DC

Anyone who visited or lived in the nation’s capital in the twentieth century would easily conclude that the city has changed in the twenty-first century. Our story maps combine Google Street View with Census data to assess these changes and describe and measure gentrification in Washington, DC.

Discover how to connect with and solve community problems and issues with by using a combination of 4 key web GIS tools: Field Surveys, story maps, web maps, and dashboards in this engaging workshop.

Protected Areas Databases in California

The California Protected Areas Database (CPAD) and the California Conservation Easement Database (CCED) are authoritative GIS databases of all protected open space lands in California and are the California element of their national counterparts. These databases are publicly accessible and they are updated twice per year. GreenInfo Network, the non-profit maintaining the databases, will conduct an overview of the data, use cases, recent updates, and key resources.

Spatial distribution of extended-spectrum beta-lactamase-producing Escherichia coli isolated from patients with community-onset bacteriuria

Introduction: The prevalence of infections caused by extended-spectrum beta-lactamase producing Escherichia coli (ESBL-E. coli) is increasing worldwide. There is growing evidence that community-onset bacteriuria caused by ESBL-E. coli may occur as outbreaks. With data from a public healthcare system in San Francisco, we found increasing prevalence of ESBL-E. coli causing community-onset bacteriuria over 6 years. We examined spatial distribution of community-onset ESBL-E. coli bacteriuria to identify such outbreaks.

Methods: We collected electronic health record data on patients with E. coli isolated from urine cultures in a public healthcare system from January 2014 to March 2020, including geocoded addresses. We identified community-onset bacteriuria as bacteriuria diagnosed < 48 hours after hospital admission or in individuals...

Interactive, Data Informed Fertilizer Applications for California Farmers

One of the most important but difficult decisions farmers make is how much fertilizer to apply and when to apply it. To address this problem in California’s small grain crops, we developed an interactive website that provides customized, site-specific nitrogen (N) fertilizer recommendations. In this presentation we describe how we integrated spatial statewide weather and soil data with user-supplied, field-specific measurements in order to provide N fertilizer recommendations.

Modeling dynamic change of marijuana use disorder in California

As marijuana use has been legalized in many states, it is important to understand the changing dynamic of the risk in marijuana use disorder (MUD). This talk explores the temporal pattern of emergency department and hospitalization discharges involving MUD at ZCTA level during 2010-2019 in California. We applied shape-based time-series clustering to...

Digital Documentation of Santa Cruz Cultural Heritage

The presentation includes my projects as a GIS Intern at California State Parks under the guidance of Denise Jaffke, Archaeologist at CSP, and Paul Veisze, Instructor at American River College. The first project is a historical barn, Cascade Ranch Barn, in Pescadero that was destroyed due to wildfire. As one of the historical landmarks in Santa Cruz County, Pigeon Point Lighthouse is the second project. The focus is on processing UAS imagery using Agisoft Metashape and Drone2Map.

Space and Time for the Milpa Forest Garden Cycle

As a critique of the temperate prejudice of the tropics, we embrace the hypothesis that the Maya Forest represents a domesticated landscape to examine the settlement and environmental patterns of the ancient Maya of El Pilar. Recognizing that land use is dependent on knowledge, skill, labor, and that the residential requirements of the landscape are not restricted to field crops,...
