Co-developing Research in Geospatial Sciences: Experiences from a Research Institute in the Co-creation of Impactful Solutions with Indigenous Communities in Aotearoa New Zealand

Introduction Guided by the UN-SDGs and focused on generating innovative geospatial research, the Geospatial Research Intitute Toi Hangarau is committed to developing, implementing, and facilitating the use and access to geospatial technologies for multiple sectors of New Zealand society. We partner with various groups, including Māori to co-design research that reflects Indigenous perspectives, related to […]

Sensing Water: First estimates of soil moisture from the Rongowai airborne remote sensing mission for GNSS-Reflectometry

Abstract In a unique partnership, the Rongowai (“sensing water” in te reo Māori) airborne remote sensing mission comprises of a next-generation Global Navigation Satellite System Reflectometry (GNSS-R) receiver (NGRx) mounted on a domestic Air New Zealand Q300 aircraft. The sensor captures reflected GNSS “signals of opportunity”, building on the legacy of novel space borne missions […]

Monitoring Hate Speech and Offensive Language on Social Media

Abstract Hate speech and offensive language content on social media platforms has increased in both volume and tone across Aotearoa. The current study aims to develop a method to monitor hate speech and offensive language using transformer-based pretrained language models (e.g., XLM-RoBERTa).  A hate speech and offensive language text classification model was developed using open-source […]

Uncertainty in Bathymetry Estimation

Introduction River bathymetry plays a crucial role in flood modelling in the form of Digital Elevation Model (DEM). It increases the reliability, accuracy and continuity of the DEM. However, river bathymetry is not always available in data-scarce areas because of the time-intensive and expensive data collection process. This leads to the development of numerous conceptual […]

Building Future Urban Development Scenarios into Assessments of Future Flood Risk

Research Problem The devastating impact of flood events demonstrates the need for more comprehensive assessments of future flood risk in urban policy. Risk assessments based on future flood projections paired with current urban plans are missing a key characteristic of the hazard – what will urban areas in Aotearoa-NZ look like in 2050 or 2100? […]

Unravelling the Biosecurity Implications of International Tourism in New Zealand

Abstract   New Zealand is a treasure of biodiversity in the heart of Pacific. Tourism is one of the main causes of the accidental introduction and spread of harmful foreign plants and animals within New Zealand. The international tourists may unintentionally bring pests, seeds, or any other unwanted materials which might pose a serious risk […]

Smoked Out: The Spatial Variation of Vape Retailer Provision in New Zealand

Abstract   We know little about the spatial patterning of e-cigarette retailers, particularly their socio-spatial patterning around schools. We obtained the nationwide vape retail locations from the Specialist Vape Retailers register, New Zealand. We identified the prevalence of vape retailers and their spatial distribution by area-level deprivation, ethnicity by Statistical Area 2 and around schools […]

Water Allocation and the Canterbury Land and Water Regional Plan

Project Aim The Land and Water Regional Plan sets limits on the quantity of fresh water in each river or stream that can be allocated to consents to take water, the minimum flow at which water take must cease, and restrictions on water take at variable flows. Are current consent conditions in line with these […]

URBAN TREES AND HOUSING INTENSIFICATION: A SPATIAL CONFLICT?

Abstract   Urban trees provide a multitude of environmental and amenity benefits for city occupants. In recognition of these benefits, many cities have developed strategies and plans seeking to protect and increase tree canopy cover. However, such objectives are in potential conflict with the housing needs of growing populations, with a recent emphasis on intensification […]
