Vegclassify: A Hybrid Deep Learning–Ndvi Greenspace Classification Tool And Gui, Huaqing Wang, Yawen Zhang, Jiaojiao Fu

Browse all Datasets

VegClassify is a hybrid, high-resolution greenspace classification tool integrating a fine-tuned deep learning model with automated NDVI threshold optimization. The tool improves accuracy and reduces subjectivity in vegetation classification using NAIP imagery. This graphical user interface (GUI) was developed to extend and simplify the use of the previously established greenspace image classification tool. The GUI provides an accessible, user‑friendly environment for running the VegClassify workflow without requiring users to interact directly with Python scripts or command‑line tools. It supports loading NAIP or other high‑resolution imagery, running deep‑learning–assisted NDVI threshold optimization, visualizing classification outputs, and exporting vegetation masks.

The underlying Python …

Slr Practitioner Needs, Daniella Hirschfeld, Kelli Archie, Emilio Mateo, James C. Arnott, Julie A. Vano

Browse all Datasets

As sea levels continue to rise, practitioners at the local and regional scale are under increased pressure to reduce risks to people and property posed by the threats of sea-level rise (SLR) and associated impacts. To achieve this, a transdisciplinary approach that integrates data-driven research with local knowledge and community engagement is necessary. As such, it is imperative the science community understands the needs of practitioners. However, there has been little qualitative assessment of adaptation practice in coastal areas, especially with a focus on the needs of practitioners in making use of current SLR science. Our mixed-methods approach began with …

Including sea-level rise (SLR) projections in coastal adaptation is increasingly recognized as crucial. Here we analyze the first global survey on the use of SLR projections comprising 253 coastal practitioners engaged in adaptation/planning from 49 countries with time frames of 2050 and 2100. While recognition of the threat of SLR is almost universally recognized, only 71% of respondents currently utilize SLR projections. Generally, developing countries have lower levels of utilization. There is no global standard in the use of SLR projections: for locations using a standard structure, 53% are planning for a single projection, while the remainder are using multiple …

Extensive community engagement occurred through USU’s senior capstone and Charrette projects, and this master plan coincides with the planning conclusions made in these projects.

This plan represents a conceptual layout and design of a greenway system in Santaquin, UT. These plans are …

The Ideology Of Critical Regionalism As A Teaching And Design Resource For The Next 100 Years Of Cela, David Hopman

Landscape Architecture Faculty Publications - Archive

This addresses the future viability of Critical Regionalism as an ongoing ideology and aesthetic construct. Regionalist trends in the early 20th century, around the time that CELA was founded, and the theory of Critical Regionalism as originally proposed in early 1980s are explained and proposed as flexible ongoing frameworks for teaching and design. Tracing the evolution and persistence of the ideas of regionalists breeds confidence for projecting the evolution of their principles forward to students of landscape architecture and to clients as adaptable verities worthy of perpetual renewal.

Green Streets To Serve Urban Sustainability: Benefits And Typology, Joowon Im

Landscape Architecture Faculty Publications - Archive

Urbanization and climate change have impacted the ecosystems of US cities. Impervious surfaces in the urbanized areas are a critical issue for both challenges and green infrastructure and can be an alternative solution to achieve urban sustainability. Green infrastructure protects urban ecosystems by reducing imperviousness by treating stormwater runoff and providing other multifaceted benefits. However, even with the great potential, its adoption is still discouraged due to limited understanding and guidance especially for the cities with a growth-driven policy. This paper proposes that green infrastructure, particularly green streets in relation to impervious surfaces, can deliver urban sustainability by providing a …

Tree Density And Diversity In Hong Kong’S Public Housing Estates: Fromprovision Injustice To Socio-Ecological Inclusiveness., Louis Shing Him Lee, C.Y. Jim, Allen Hao Zhang

Faculty of Design & Environment (THEi)

Socio-economically underprivileged urban communities might suffer from restricted access to urban forests. Environmental injustice research on urban greenery in Asian cities is lacking. Public housing estates in Hong Kong, accommodating low-income households and over half of the 7.45 million population, were investigated for injustice in tree provision. Two clustering schemes used socio-economic and ecological characteristics to classify 93 estates. Factor analysis of 14 socio-economic variables identified four factors related to deprivation, namely ageing population, overcrowding, working poor with high academic qualifications, and marginalised language minorities. Principal component analysis of six ecological indices returned two components related to tree density and …

Tree Distribution, Morphology And Modelled Air Pollution In Urban Parks, Yang Xing, Peter Brimblecombe, Sifeng Wang, Allen Hao Zhang

Faculty of Design & Environment (THEi)

Trees offer a range of ecosystem services and remain important in providing human benefits. However, emerging literature questions the long-accepted view of trees being able to improve air quality in urban parks. The aerodynamic effect of trees was identified as a major reason for the change of pollutant distribution in near-road parks, where trees can act as porous barriers and cause localised concentration increase. Although not yet fully developed, planting strategies aiming to mitigate the negative effect of vegetation on air quality should be encouraged in future park design. In this study, we explored the effect of tree planting design …

Neighborhood Variation Of Sustainable Urban Morphologicalcharacteristics, P. C. Lai, Sissi Si Chen, C. T. Low, Ester Cerin, Robert Stimson, Py Paulina Wong

Faculty of Design & Environment (THEi)

Compact cities and their urban forms have implications on sustainable city development because of high density urban settlement, increased accessibility, and a balanced land use mix. This paper uses quantitative means of understanding urban morphological characteristics with reference to the differing qualities of the urban form (i.e., street patterns, building volumes, land uses and greenery). The results, based on 89 neighborhood communities of Hong Kong, show varying degrees of regional differences in the urban built form supported by numerical statistics and graphical illustrations. This paper offers empirical evidence on some morphological characteristics that can be estimated objectively using modern geospatial …

Exploring Policy Options To Combat Illegal Micro-Apartments In Hong Kong, Yung Yau, Daniel Chi Wing Ho

Faculty of Design & Environment (THEi)

Illegal building can take multiple forms, including squatter settlements and illegal building extensions. Among the various forms of illegal building, illegal microapartments (IMAs), which take the form of unauthorised subdivided housing units, have recently aroused wide public concern in Hong Kong. On account of their unlawful nature, IMAs pose serious threats to the safety of local communities by undermining structural stability and fire safety in buildings. They may also adversely affect natural lighting and ventilation for building occupants. Fatal fires in buildings with IMAs in recent years have demonstrated the painful consequence of ignoring this issue in the city. Nonetheless, …

Transfer Of Antibiotics From Wastewater Or Animal Manure To Soil Andedible Crops., Livia Min Pan, L.M. Chu

Faculty of Design & Environment (THEi)

Antibiotics are added to agricultural fields worldwide through wastewater irrigation or manure application, resulting in antibiotic contamination and elevated environmental risks to terrestrial environments and humans. Most studies focused on antibiotic detection in different matrices or were conducted in a hydroponic environment. Little is known about the transfer of antibiotics from antibiotic-contaminated irrigation wastewater and animal manure to agricultural soil and edible crops. In this study, we evaluated the transfer of five different antibiotics (tetracycline, sulfamethazine, norfloxacin, erythromycin, and chloramphenicol) to different crops under two levels of antibiotic-contaminated wastewater irrigation and animal manure fertilization. The final distribution of tetracycline (TC), …

Prediction Of The Root Anchorage Of Native Young Plants Using Bayesian Inference, Ryan Wai Man Yan, Lin Zhang, Flora T. Y. Leung, Ka-Veng Yuen

Faculty of Design & Environment (THEi)

The maximum vertical uproot resistance (Pmax) of a plant can be used to indicate its stability. Attempts were made to predict the Pmax of a plant empirically from some of its size parameters. In practice, an infinite number of empirical models with different complexities can be formulated. This study presents a Bayesian model class selection method to evaluate the plausibility of each empirical model among a list of model candidates. The models were ranked to identify the most plausible one. A database of vertical uproot resistance of four shrubs and trees native to Hong Kong was first compiled by performing …

Restraints On Design: Adventure Playgrounds And Landscape Architecture, Karen Teague

Landscape Architecture Masters & Design Theses - Archive

This thesis examines minimally designed adventure playgrounds, what landscape architects, landscape designers and educators think about this type of play space and if it could become a larger part of the American play inventory. It also explores the roles landscape architects have in designing these play areas while still allowing the intended users, the children, to take a lead design role and attain the intended benefits of the space. To do this, this study explores the origins of adventure playgrounds, their ability to develop in the United States, and how landscape architects are involved in this process. Landscape architects, designers …

Study Of Environmental Variables Affecting Walkability: Learning From Main Street In Downtown Fort Worth, Xitong Li

Landscape Architecture Masters & Design Theses - Archive

Walking has widely been considered by researchers to be important for physical health and a key to increasing social interactions in the local community (Layden, 2003), as well as a mode of transportation in such an era of high fossil fuel price (Maibach, 2009). The negative effects of low-density, automobile-dependent, segregated-use patterns of land and transportation systems typical of postwar suburban development are attracting public health attention. As a result, more designers and urban planners are beginning to take the concept of "walkable design" into consideration in their projects. In order to promote walking activity in terms of urban design, …

Complete Streets Design Elements And Their Impact On Travel Behavior: Learning From The Bagby Street Reconstruction In Houston, Tx, Alexandra T. Tracz

Landscape Architecture Masters & Design Theses - Archive

There are several studies linking travel behavior to various other topics within urban design but none directly examine Complete Streets. This travel behavior study is significant in that it looks at specific streetscape design features rather than studying density or land use of a particular area. This research examines if and how travel behavior is influenced by specific design elements on Complete Streets using Bagby Street Reconstruction in Houston, Texas as a case study. Bagby Street Reconstruction is one of the first Complete Streets projects in Houston completed by Design Workshop and Walter P Moore. The project is a section …

The Relationship Between Park Characteristics And Human Social Behavior: Learning From Main Street Garden In Dallas, Texas, Junjie He

Landscape Architecture Masters & Design Theses - Archive

The objective of this thesis is to study the relationship between park characteristics and human social behavior in Main Street Garden Park in Dallas. Whyte highlights several characteristics that promote the successful use of urban spaces: sitting space, nature, concessions, pathways, and triangulation (Whyte 1980). The ways in which these five characteristics influence human social behavior is the focus of this thesis. The aspects of human social behavior studied in this thesis are the proportions of couples, women, children, and pet-owners; usage times; self-congestion, meaning the amount and location of new interaction; and individualism. Using Main Street Garden in downtown …
