(University of Waterloo, 2012-04-30)This thesis seeks to highlight the importance of a geographic and culturally specific knowledge base to guide natural resource management and governance policy, particularly within the West African context. In order to ... -
Deep Learning for 3D Information Extraction from Indoor and Outdoor Point Clouds
(University of Waterloo, 2021-01-07)This thesis focuses on the challenges and opportunities that come with deep learning in the extraction of 3D information from point clouds. To achieve this, 3D information such as point-based or object-based attributes ... -
Deep Residual Networks for Hyperspectral Image Classification
(Institute of Electrical and Electronics Engineers, 2017-07-25)Deep neural networks can learn deep feature representation for hyperspectral image (HSI) interpretation and achieve high classification accuracy in different datasets. However, counterintuitively, the classification ... -
Deeper Burning Increases Available Phosphorus, Promotes Moss Growth, and Carbon Dioxide Uptake in a Fen Peatland One-Year Post-Wildfire in Fort McMurray, AB
(University of Waterloo, 2019-01-25)Carbon storage in northern peatlands is estimated to be ~795 Tg, equivalent to ~40% of atmospheric CO2. Peatlands are dominant features of the Western Boreal Plains (WBP), which are experiencing a regime shift to a ... -
Deriving Spatial Patterns of Severe Rainfall in Southern Ontario
(University of Waterloo, 2010-04-13)Severe weather is a natural product of the earth’s atmosphere. Water delivered by storms sustains important biophysical functions whereas from a human perspective severe weather can have negative effects when damage is ... -
Designing successful stakeholder participatory processes for environmental planning: A case study of subwatershed planning in Hamilton, Ontario
(University of Waterloo, 2009-08-28)Stakeholder participation has become a valuable tool for agencies in the field of environmental planning. The potential benefits, for both agencies and individuals, of involving stakeholders in the planning process have ... -
Detecting Land Cover Change over a 20 Year Time Period in the Niagara Escarpment Plan Using Satellite Remote Sensing
(University of Waterloo, 2009-04-27)The Niagara Escarpment is one of Southern Ontario’s most important landscapes. Due to the nature of the landform and its location, the Escarpment is subject to various development pressures including urban expansion, ... -
Developing a Prototype Web-based Application for Non-Point Source Pollution Assessment in the Songtao Watershed, Hainan, China
(University of Waterloo, 2009-01-28)The Songtao reservoir, located in the center of Hainan province, is one of the ten biggest reservoirs in China. Since agriculture is the main industry in the watershed, non-point source (NPS) pollution is the primary ... -
Developing a radar-based machine learning snowfall retrieval algorithm
(University of Waterloo, 2023-01-03)As global temperatures continue to rise, snowfall patterns are expected to respond in a complex, nonlinear manner. Changes in the quantity of snowmelt-derived freshwater will impact global water-energy budgets, flood ... -
Developing a Suitability Index for Residential Land Use: A case study in Dianchi Drainage Area
(University of Waterloo, 2006)The conflict between residential land and agriculture land in China is increasingly sharpened, especially when some urban development began to sprawl to the suburban and rural areas. In order to plan land resources ... -
Developing Parameter Constraints for Radar-based SWE Retrievals
(University of Waterloo, 2021-09-28)Terrestrial snow is an important freshwater reservoir with significant influence on the climate and energy balance. It exhibits natural spatiotemporal variability which has been enhanced by climate change, thus it is ... -
Development of an Oil Spill Emergency Mapping System Using Internet GIS
(University of Waterloo, 2010-09-28)ince the 1970s, environmental monitoring in China has formed a complete web across the country with over 2000 monitoring stations. China State Environmental Protection Administration (SEPA) has published an annual report ... -
The Differing Influences of Soil Moisture and Antecedent Soil Moisture on the Timing and Magnitude of N2O Production
(University of Waterloo, 2012-10-22)Riparian soils are thought to be potential hotspots for nitrous oxide (N2O) fluxes from incomplete denitrification, with soil moisture cited as a primary controller, however, because there are multiple potential pathways ... -
Digital Terrain Models Generation from Airborne LiDAR Point Clouds Using A Multi-scale Terrain Filtering Method
(University of Waterloo, 2012-05-23)A Digital Terrain Model (DTM) is an important topographic product, required in many applications. Data needed to create a DTM was traditionally obtained via land surveying, however this method can be costly and time consuming ... -
