DNA barcoding of forensically important blow flies (Diptera: Calliphoridae) within the Western Cape of South Africa
… this requires the comparison of DNA barcodes to reference data from known species. However, there is a lack of DNA barcode reference data of forensically relevant Calliphoridae species in the Western Cape (South Africa). DNA barcodes were generated for the COI and ITS2 markers for 41 forensically …

Characterization of a Spiking Neuron Model via a Linear Approach
… method is implemented to fit the model to the reference data. Through manipulation of the system dynamics, the threshold voltage can be obtained as a realizable model that is linear in the unknown parameters. This linearly parametrized realizable model is then utilized inside a prediction error …

Land Cover of Virginia From Landsat Thematic Mapper Imagery
… knowledge, and other maps were used as training data. Aerial videography transects were flown to acquire reference data. Due to the spatial inaccuracies inherent in the videography reference data, only homogeneous land cover areas were used in the accuracy assessment. The results of the overall …

Fidelity versus Scalability: Deep Learning in Forest Remote Sensing
… based on manual measurements is able to provide data at this granularity, but limits the spatial scale and temporal resolution at which forest structure and diversity can be assessed. Aerial data appear to offer a promising solution to this problem by enabling rapid capture of forest data at …

Evaluating the Potential for Estimating Age of Even-aged Loblolly Pine Stands Using Active and Passive Remote Sensing Data
Data from an airborne laser scanner, a dual-band interferometric synthetic aperture radar (DBInSAR), and Landsat were evaluated for estimating ages of even-aged loblolly pine stands in Appomattox-Buckingham State Forest, Virginia, U.S.A. The DBInSAR data were acquired using the GeoSAR sensor in …

Effects of Aerial LiDAR Data Density on the Accuracy of Building Reconstruction
… a point of diminished returns at which higher data density no longer contributes meaningfully to higher accuracy in the end product. We investigate this relationship by subsampling a high-density dataset from the City of Surrey, BC to different densities and inputting each subsampled dataset to …

Assessing the Utility of Imaging Radar for Identifying White Sand Vegetation Structure
… the State of Amazonas. Due to the lack of ground reference data, a classified map by Capurucho et al. (2013), generated using Landsat data, was used as a comparison and reference. JAXA’s ALOS-1 PALSAR (L-band), ESA’s Sentinel-1A (C-band) and NASA’s SRTM sensors were used for land classification. …
