Book Synopsis Unmanned Aerial-vehicle-based Measurement of Urban Forests by : Earle W. Isibue
Download or read book Unmanned Aerial-vehicle-based Measurement of Urban Forests written by Earle W. Isibue and published by . This book was released on 2019 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human and natural forces continually act on urban forests to producing changes that leading to trees being removed or replanted. Therefore, to manage the urban forest effectively, periodic inventories are needed to ensure that information about the urban forest is current and comprehensive. This task has traditionally been accomplished by manual ground-based field surveys, or more recently by lidar; however, these methods are expensive, either in terms of time, labor, or cost. This project proposes a novel method of using Unmanned Aerial Vehicles (UAVs) to more accurately measure urban tree height and trunk diameter than is currently possible using conventional approaches. This method uses Structure from Motion (SfM) processing of images captured from UAVs to derive these measurements. A comparative analysis was performed on a sample of approximately 1,000 trees testing the accuracy of these SfM measurements when compared to manually field measured or lidar based methods. Results suggest that in an urban environment the SfM method produces estimates of tree height (R2 = 0.96; RMSE = 1.91 m) and diameter (R2 = 0.98; RMSE = 3 cm) when compared to manual field measurements.

Book Synopsis Forestry Applications of Unmanned Aerial Vehicles (UAVs) 2019 by : Alessandro Matese
Download or read book Forestry Applications of Unmanned Aerial Vehicles (UAVs) 2019 written by Alessandro Matese and published by MDPI. This book was released on 2020-11-23 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAVs) are new platforms that have been increasingly used in the last few years for forestry applications that benefit from the added value of flexibility, low cost, reliability, autonomy, and capability of timely provision of high-resolution data. The main adopted image-based technologies are RGB, multispectral, and thermal infrared. LiDAR sensors are becoming commonly used to improve the estimation of relevant plant traits. In comparison with other permanent ecosystems, forests are particularly affected by climatic changes due to the longevity of the trees, and the primary objective is the conservation and protection of forests. Nevertheless, forestry and agriculture involve the cultivation of renewable raw materials, with the difference that forestry is less tied to economic aspects and this is reflected by the delay in using new monitoring technologies. The main forestry applications are aimed toward inventory of resources, map diseases, species classification, fire monitoring, and spatial gap estimation. This Special Issue focuses on new technologies (UAV and sensors) and innovative data elaboration methodologies (object recognition and machine vision) for applications in forestry.

Book Synopsis Quantifying the Urban Forest Environment Using Dense Discrete Return LiDAR and Aerial Color Imagery for Segmentation and Object-level Biomass Assessment by : Madhurima Bandyopadhyay
Download or read book Quantifying the Urban Forest Environment Using Dense Discrete Return LiDAR and Aerial Color Imagery for Segmentation and Object-level Biomass Assessment written by Madhurima Bandyopadhyay and published by . This book was released on 2015 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The urban forest is becoming increasingly important in the contexts of urban green space and recreation, carbon sequestration and emission offsets, and socio-economic impacts. In addition to aesthetic value, these green spaces remove airborne pollutants, preserve natural resources, and mitigate adverse climate changes, among other benefits. A great deal of attention recently has been paid to urban forest management. However, the comprehensive monitoring of urban vegetation for carbon sequestration and storage is an under-explored research area. Such an assessment of carbon stores often requires information at the individual tree level, necessitating the proper masking of vegetation from the built environment, as well as delineation of individual tree crowns. As an alternative to expensive and time-consuming manual surveys, remote sensing can be used effectively in characterizing the urban vegetation and man-made objects. Many studies in this field have made use of aerial and multispectral/hyperspectral imagery over cities. The emergence of light detection and ranging (LiDAR) technology, however, has provided new impetus to the effort of extracting objects and characterizing their 3D attributes - LiDAR has been used successfully to model buildings and urban trees. However, challenges remain when using such structural information only, and researchers have investigated the use of fusion-based approaches that combine LiDAR and aerial imagery to extract objects, thereby allowing the complementary characteristics of the two modalities to be utilized In this study, a fusion-based classification method was implemented between high spatial resolution aerial color (RGB) imagery and co-registered LiDAR point clouds to classify urban vegetation and buildings from other urban classes/cover types. Structural, as well as spectral features, were used in the classification method. These features included height, flatness, and the distribution of normal surface vectors from LiDAR data, along with a non-calibrated LiDAR-based vegetation index, derived from combining LiDAR intensity at 1064 nm with the red channel of the RGB imagery. This novel index was dubbed the LiDAR-infused difference vegetation index (LDVI). Classification results indicated good separation between buildings and vegetation, with an overall accuracy of 92% and a kappa statistic of 0.85. A multi-tiered delineation algorithm subsequently was developed to extract individual tree crowns from the identified tree clusters, followed by the application of species-independent biomass models based on LiDAR-derived tree attributes in regression analysis. These LiDAR-based biomass assessments were conducted for individual trees, as well as for clusters of trees, in cases where proper delineation of individual trees was impossible. The detection accuracy of the tree delineation algorithm was 70%. The LiDAR-derived biomass estimates were validated against allometry-based biomass estimates that were computed from field-measured tree data. It was found out that LiDAR-derived tree volume, area, and different distribution parameters of height (e.g., maximum height, mean of height) are important to model biomass. The best biomass model for the tree clusters and the individual trees showed an adjusted R-Squared value of 0.93 and 0.58, respectively. The results of this study showed that the developed fusion-based classification approach using LiDAR and aerial color (RGB) imagery is capable of producing good object detection accuracy. It was concluded that the LDVI can be used in vegetation detection and can act as a substitute for the normalized difference vegetation index (NDVI), when near-infrared multiband imagery is not available. Furthermore, the utility of LiDAR for characterizing the urban forest and associated biomass was proven. This work could have significant impact on the rapid and accurate assessment of urban green spaces and associated carbon monitoring and management."--Abstract.

Download or read book Use of Unmanned Aerial Vehicle Systems (UAVs) for High Detail, Short Range Imaging of Epiphytic Tropical Species written by Matthew Lehmitz and published by . This book was released on 2021 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many species that exist primarily or solely in canopies of trees. These species are often understudied because of the logistical challenges of reaching high enough to observe them. This work proposes a solution to this quandary in the form of UAVs or Unmanned Aerial Vehicles. These systems can be operated remotely and carry useful equipment for observation and measurement. UAVs have been in use for some time in forests and what sets this particular approach apart is the extreme close range of the photography. The goal was to acquire the best possible high quality photos at the closest range. This not only helps to avoid the issue of foliage and other materials blocking the way but also allows for details and access that might otherwise not be available even with extensive zoom features on a high quality camera. In order that this should be as available as possible to the widest range of researchers relatively low cost, and easy to use, UAVs were selected. These represented off-the-shelf options that could be put into the field with limited additional experience, training or alteration. To achieve this goal a series of tests and practical demonstrations were conducted utilizing the UAV systems. Elements included testing the Cameras for visual quality and range, determining the range of flight, understanding the best angles and lighting for photography and more. These elements were taken together to provide documentation on best practices in using UAVs for canopy remote sensing.
