摘要

The work from the A14 proved that with careful planning and processing an enhanced high precision model can be achieved. However there are several things that need to be taken into consideration. The quality of the LiDAR point cloud is directly linked to the quality of the tools used. The system calibration, flight planning, data capture, GPS and survey data all need to be correct, should any one of them be incorrect then the whole data set is affected. Great care must be taken when collecting and processing the data. Enhanced models are not suited to all survey or surface types. Due to the smoothing applied to the data, small variations in the surface -such as kerbs - can be lost, so it is best suited for smooth consistent surface types, such as roads.

7. The Nak’azdli Whu’ten is a First Nations community located in northern British Columbia Canada. They have prioritized support for the mental health and wellbeing of their Elders and were keen to strengthen intergenerational linkages in the community to preserve cultural wisdom held by the elders for future generations. We co-created a digital storytelling workshop using technology to facilitate knowledge-sharing between Elders and youths. This pilot 10 session workshop involved all grade 6 and 7 students at a First Nations school and 20 First Nations Elders. Students recorded the Elders who orally shared stories and then added imagery and sounds to capture their understandings and create a digital story. The workshop was led by elders. Our project demonstrates one way to document oral histories while simultaneously building intergenerational relationships. We will discuss how this project successfully fostered intergenerational relationships, helped preserve cultural identity, and reduced social isolation of First Nations Elders. [O] .
