Reflections On Community Planning In San Francisco, Rachel Brahinsky, Miriam Chion, Lisa Feldstein
Reflections On Community Planning In San Francisco, Rachel Brahinsky, Miriam Chion, Lisa Feldstein
Politics
This paper builds on a dialogue between barrio planners and municipal planners on spatial and economic changes in San Francisco’s Mission District. The Mission is a predominantly Latino neighborhood with vibrant streets that have reflected and been transformed by the investments and displacement of recent decades. Though the Mission has seen tremendous upheaval with the influx of new capital and communities, this paper contends that efforts of community members shaped the development of the neighborhood with street-level planning expertise. We find that an attempt by community members to define their own development proposals and engage in land use decisions– rather …
Land Surface Phenologies And Seasonalities Using Cool Earthlight In Mid-Latitude Croplands, Woubet G. Alemu, G. M. Henebry
Land Surface Phenologies And Seasonalities Using Cool Earthlight In Mid-Latitude Croplands, Woubet G. Alemu, G. M. Henebry
Natural Resource Management Faculty Publications
Phenology deals with timing of biotic phenomena and seasonality concerns temporal patterns of abiotic variables. Studies of land surface phenology (LSP) and land surface seasonality (LSS) have long been limited to visible to near infrared (VNIR) wavelengths, despite degradation by atmospheric effects and solar illumination constraints. Enhanced land surface parameters derived from passive microwave data enable improved temporal monitoring of agricultural land surface dynamics compared to the vegetation index data available from VNIR data. LSPs and LSSs in grain growing regions of the Volga River Basin of Russia and the spring wheat belts of the USA and Canada were characterized …
Identifying Potential Wilderness Areas On The Fremont-Winema National Forest With Arcgis Modelbuilder, Zach Adams
Identifying Potential Wilderness Areas On The Fremont-Winema National Forest With Arcgis Modelbuilder, Zach Adams
Geography and the Environment: Graduate Student Capstones
The Fremont-Winema National Forest administers over two million acres in south central Oregon. Part of managing this landscape includes overseeing existing wilderness areas and identifying new potential wilderness areas. In the past this process has been cumbersome, with little thought given to standardizing the effort across the administrative area. This project was an effort to develop a geospatial model that incorporates U.S. Forest Service spatial datasets ultimately standardizing the potential wilderness identification process during site specific NEPA analysis.
Spacing Units In The Greater Wattenberg Area, Tera Dillon
Spacing Units In The Greater Wattenberg Area, Tera Dillon
Geography and the Environment: Graduate Student Capstones
Horizontal wells are the most commonly drilled wells in the Wattenberg Field, located in Weld County, Colorado. Petroleum engineers have become interested in determining how many horizontal wells can economically be drilled per section in this vertically, well-developed field. Using the Colorado Oil and Gas Conservation Commission’s spacing unit regulations as a guide, a GIS workflow was developed to create the deliverables required for further analysis. Spacing units were created by applying a buffer to horizontal well surveys, and using this buffer to select intersecting quarter-quarter sections. The selected quarter-quarter sections were simplified using the dissolve tool and then spatially …
Evaluation Of A Coupled Event-Driven Phenology And Evapotranspiration Model For Croplands In The United States Northern Great Plains, V. Kovalskyy, G. M. Henebry, D. P. Roy, B. Adusei, M. Hansen, G. Senay, D. M. Mocko

Natural Resource Management Faculty Publications
A new model coupling scheme with remote sensing data assimilation was developed for estimation of daily actual evapotranspiration (ET). The scheme consists of the VegET, a model to estimate ET from meteorological and water balance data, and an Event Driven Phenology Model (EDPM), an empirical crop specific model trained on multiple years of flux tower data transformed into six types of environmental forcings that are called “events” to emphasize their temporally discrete character, which has advantages for modeling multiple contingent influences. The EDPM in prognostic mode supplies seasonal trajectories of normalized difference vegetation index (NDVI); whereas in diagnostic mode, it …
A Conceptual Model Of Exploration Wayfinding: An Integrated Theoretical Framework And Computational Methodology, Matthew Lee Tenney
A Conceptual Model Of Exploration Wayfinding: An Integrated Theoretical Framework And Computational Methodology, Matthew Lee Tenney
Graduate Theses and Dissertations
This thesis is an attempt to integrate contending cognitive approaches to modeling wayfinding behavior. The primary goal is to create a plausible model for exploration tasks within indoor environments. This conceptual model can be extended for practical applications in the design, planning, and Social sciences. Using empirical evidence a cognitive schema is designed that accounts for perceptual and behavioral preferences in pedestrian navigation. Using this created schema, as a guiding framework, the use of network analysis and space syntax act as a computational methods to simulate human exploration wayfinding in unfamiliar indoor environments. The conceptual model provided is then implemented …
Contemporary Problems Of Gis Interoperability: A Review Of Gis Integration With Current Technology, Tim Jones
Contemporary Problems Of Gis Interoperability: A Review Of Gis Integration With Current Technology, Tim Jones
Geography and the Environment: Graduate Student Capstones
This paper examines GIS interoperability with three current technology trends: Open Source, Smart Devices and Web 2.0. It firsts takes a look at both varying definitions of interoperability as well as different types of interoperability. The author samples a variety of GIS formats with examples of each of the said technologies as a way to measure the current state of GIS interoperability with current technological trends. GIS functions such as viewing, editing and analyzing spatial data are used as a scoring matrix to determine the level of interoperability. The methodology of measure focuses on a technical level of interoperability and …
Baseline Study Of The Relationship Between Green Space And Age, Chris Schulze
Baseline Study Of The Relationship Between Green Space And Age, Chris Schulze
Geography and the Environment: Graduate Student Capstones
Current research on green space and human health is spread among many academic disciplines and is growing. To aid researchers and local governments in understanding the relationship between the two, this study presents a baseline analysis of the spatial relationship between green space and age. It considers how a city’s population is distributed around green space and looks at spatial and statistical patterns related to age and location. This study identifies a gap in current research and looks at green space and age in a geographic manner. The findings of this literature review and analysis provide researchers with another way …

GSCE Faculty Publications
With the advent of the free U.S. Landsat data policy it is now feasible to consider the generation of global coverage 30 m Landsat data sets with temporal reporting frequency similar to that provided by the monthly Web Enabled Landsat (WELD) products. A statistical Landsat metadata analysis is reported considering more than 800,000 Landsat 5 TM and Landsat 7 ETM + acquisitions obtained from the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center archive. The global monthly probabilities of acquiring a cloud-free land surface observation for December 1998 to November 2001 (2000 epoch) and from December 2008 …
Augmented Realities And Uneven Geographies: Exploring The Geolinguistic Contours Of The Web, Mark Graham, Matthew Zook
Augmented Realities And Uneven Geographies: Exploring The Geolinguistic Contours Of The Web, Mark Graham, Matthew Zook
Geography Faculty Publications
This paper analyzes the digital dimensions of places as represented by online, geocoded references to the economic, social, and political experiences of the city. These digital layers are invisible to the naked eye, but form a central component of the augmentations and mediations of place enabled by hundreds of millions of mobile computing devices and other digital technologies. The analysis highlights how these augmentations of place differ across space and language and highlights both the differences and some of the causal factors behind them. This is performed through a global study of all online content indexed within Google Maps, and …
