In this study, we used image-based and manual field measurements to develop and validate a methodology to simulate strawberry (Fragaria \u00d7 ananassa Duch.) plant canopies throughout the Florida strawberry growing season. The simulated plants were used to create a synthetic image using radiative transfer modeling. Observed canopy properties were incorporated into an L-system simulator, and a series of strawberry canopies corresponding to specific weekly observation dates were created. The simulated canopies were compared visually with actual plant images and quantitatively with in-situ leaf area throughout the strawberry season. A simple regression model with L-system-derived and in-situ total leaf areas had an Adj\u00a0R2 value of 0.78. The L-system simulated canopies were used to derive information needed for image simulation, such as leaf area and leaf angle distribution. Spectral and plant canopy information were used to create synthetic high spatial resolution multispectral images using the Discrete Anisotropic Radiative Transfer (DART) software. Vegetation spectral indices were extracted from the simulated image and used to develop multiple regression models of in-situ biophysical parameters (leaf area and dry biomass), achieving Adj\u00a0R2 values of 0.63 and 0.50, respectively. The Normalized Difference Vegetation Index (NDVI) and the Red Edge Simple Ratio (SRre) vegetation indices, which utilize the red, red edge, and near infrared bands of the spectrum, were identified as statistically significant variables (p < 0.10). This study showed that both geometric (canopy seize metrics) and spectral variables were successful in modeling in-situ biomass and leaf area. Combining the geometric and spectral variables, however, only slightly improved the prediction model. These results show the feasibility of simulating strawberry canopies and images with inherent geometrical, topological, and spectral properties of real strawberry plants. The simulated canopies and images can be used in applications beyond creating realistic computer graphics for quantitative applications requiring the depiction of vegetation biological processes, such as stress modeling and remote sensing mission planning.<\/jats:p>","DOI":"10.3390\/rs14030548","type":"journal-article","created":{"date-parts":[[2022,1,26]],"date-time":"2022-01-26T02:07:11Z","timestamp":1643162831000},"page":"548","source":"Crossref","is-referenced-by-count":3,"title":["Radiative Transfer Image Simulation Using L-System Modeled Strawberry Canopies"],"prefix":"10.3390","volume":"14","author":[{"given":"Zhen","family":"Guan","sequence":"first","affiliation":[{"name":"Gulf Coast Research and Education Center, School of Forest Fisheries, and Geomatics Sciences, University of Florida, Plant City, FL 33563, USA"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-6182-4017","authenticated-orcid":false,"given":"Amr","family":"Abd-Elrahman","sequence":"additional","affiliation":[{"name":"Gulf Coast Research and Education Center, School of Forest Fisheries, and Geomatics Sciences, University of Florida, Plant City, FL 33563, USA"}]},{"given":"Vance","family":"Whitaker","sequence":"additional","affiliation":[{"name":"Gulf Coast Research and Education Center, Department of Horticultural Sciences, University of Florida, Plant City, FL 33563, USA"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-6820-0821","authenticated-orcid":false,"given":"Shinsuke","family":"Agehara","sequence":"additional","affiliation":[{"name":"Gulf Coast Research and Education Center, Department of Horticultural Sciences, University of Florida, Plant City, FL 33563, USA"}]},{"given":"Benjamin","family":"Wilkinson","sequence":"additional","affiliation":[{"name":"School of Forest Fisheries, and Geomatics Sciences, University of Florida, Plant City, FL 33563, USA"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-6645-8837","authenticated-orcid":false,"given":"Jean-Philippe","family":"Gastellu-Etchegorry","sequence":"additional","affiliation":[{"name":"Centre d\u2019Etudes Spatiales de la BIOsph\u00e8re\u2014UPS, CNES, CNRS, IRD, Universit\u00e9 de Toulouse, 31401 Toulouse, France"}]},{"given":"Bon","family":"Dewitt","sequence":"additional","affiliation":[{"name":"School of Forest Fisheries, and Geomatics Sciences, University of Florida, Plant City, FL 33563, USA"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"62","DOI":"10.1071\/FP16167","article-title":"Approaches to three-dimensional reconstruction of plant shoot topology and geometry","volume":"44","author":"Gibbs","year":"2017","journal-title":"Funct.
