Point clouds captured from Unmanned Aerial Systems are increasingly relied upon to provide information describing the structure of forests. The quality derived these point is dependent on a range variables, including type and forest, weather conditions flying parameters. A key requirement achieve accurate estimates height based metrics forest source ground information. This study explores availability reliability surface points available within in six forests different (canopy cover height),...

Floating and washed ashore marine plastic debris (MPD) is a growing environmental challenge. It has become evident that secluded locations including the Arctic, Antarctic, remote islands are being impacted by pollution generated thousands of kilometers away. Optical sensing MPD an emerging field can aid in monitoring environments where in-person observation data collection not always feasible. Here we evaluate spectral features visible to shortwave infrared regions for detecting varying...

Marine plastic debris (MPD) is a globally relevant environmental challenge, with an estimated 8 million tons of synthetic entering the marine environment each year. Plastic has been found in all parts environment, including surface layers ocean, within water column, coastal waters, on benthic layer and beaches. While research detecting MPD using remote sensing increasing, most it focuses floating open rather than However, beaches present challenges that are unique from other environment. In...

A field spectroscopy metadata standard is defined as those data elements that explicitly document the dataset and protocols, sampling strategies, instrument properties environmental logistical variables. Standards for affect quality, completeness, reliability, usability of datasets created in situ. Currently there no standardized methodology documentation situ or metadata.

Reproducibility is widely regarded as crucial for scientific studies, yet there still a lack of reproducibility in geospatial research. New sources crowdsourced geoinformation provide new opportunities, but also complicate the situation. Consequently, untapped potential domain disaster response to reuse methodology. Shared, executable workflows can help improving reproducibility. In this paper, we created reproducible from three published studies using geosocial media sources. They have been...
