Download or read book Feasibility of Consistently Estimating Timber Volume Through Landsat based Remote Sensing Applications written by Renaldo Josue Salazar Arroyo and published by . This book was released on 2014 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mississippi Institute for Forest Inventory (MIFI) is the only cost-effective large-scale forest inventory system in the United States with sufficient precision for producing reliable volume/weight/biomass estimates for small working circle areas (procurement areas). When forest industry is recruited to Mississippi, proposed working circles may overlap existing boundaries of bordering states leaving a gap of inventory information, and a remote sensing-based system for augmenting missing ground inventory data is desirable. The feasibility of obtaining acceptable cubic foot volume estimates from a Landsat-derived volume estimation model (Wilkinson 2011) was assessed by: 1) an initial study to temporally validate Landsat-derived cubic foot volume outside bark to a pulpwood top estimates in comparison with MIFI ground truth inventory plot estimates at two separate time periods, and 2) re-developing a regression model based on remotely sensed imagery in combination with available MIFI plot data. Initial results failed to confirm the relationships shown in past research between radiance values and volume estimation. The complete lack of influence of radiance values in the model led to a re-assessment of volume estimation schemes. Data outlier trimming manipulation was discovered to lead to false relationships with radiance values reported in past research. Two revised volume estimation models using age, average stand height, and trees per-acre and age and height alone as independent variables were found sufficient to explain variation of volume across the image. These results were used to develop a procedure for other remote sensing technologies that could produce data with sufficient precision for volume estimation where inventory data are sparse or non-existent.

Download or read book Measurements and Estimations of Forest Stand Parameters Using Remote Sensing written by Donald A. Stellingwerf and published by VSP. This book was released on 1997-08 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Generally speaking, the use of remote sensing imagery will reduce field work. Remote sensing imagery gives an overall view of the forest in addition to more detailed information, the extent of which depends mainly on scale and film used in case of analogue data, and mainly on pixel size in case of digital data. This book deals with measurements and estimations of forest stand parameters using aerial photographic, aircraft and satellite scanning data, radar and laser imagery. It includes technical and statistical information of practical examples from both temperate and tropical forests. Statistical analysis of measurement data and sampling techniques are given when required. The obtained results are compared with those from other techniques, showing their relative advantage or disadvantage.

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.
