This is an out-of-date version of our pRF mapping toolbox and no longer supported! While this version should be stable, USE IT AT YOUR OWN RISK! We instead recommend our new version SamSrf X, which will continue to be updated with bugfixes and new features. You can also use the new version for further analysis of maps from the old version.SamSrf X is available for download at:http://osf.io/2rgsm.--------------------------------------------------------------------------------Version: 5.84 (18-09-2017)Our Matlab toolbox for pRF mapping analysis. Uses SPM8 or SPM12 and FreeSurfer functionality for preprocessing. Also requires Statistics Toolbox, Optimization Toolbox, and Curve Fitting Toolbox (not strictly necessary) for Matlab.An extensive documentation "cookbook" is included. Please contact Sam (sampendu.wordpress.com) for any questions but please be advised that we are not able to provide tech support for people we don't collaborate with.As of version 5.63, we included a new tutorial explaining how to delineate visual areas using the DelineationTool in MatLab and giving advice on what to do with tricky retinotopic maps.

This data release provides remotely sensed data, field measurements, and MATLAB code associated with an effort to produce image-derived velocity maps for a reach of the Sacramento River in California's Central Valley. Data collection occurred from September 16-19, 2024, and involved cooperators from the Intelligent Robotics Group from the National Aeronautics and Space Administration (NASA) Ames Research Center and the National Oceanographic and Atmospheric Administration (NOAA) Southwest Fisheries Science Center. The remotely sensed data were obtained from an Uncrewed Aircraft System (UAS) and are stored in Robot Operating System (ROS) .bag files. Within these files, the various data types are organized into ROS topics including: images from a thermal camera, measurements of the distance from the UAS down to the water surface made with a laser range finder, and position and orientation data recorded by a Global Navigation Satellite System (GNSS) receiver and Inertial Measurement Unit (IMU) during the UAS flights. This instrument suite is part of an experimental payload called the River Observing System (RiOS) designed for measuring streamflow and further detail is provided in the metadata file associated with this data release. For the September 2024 test flights, the RiOS payload was deployed from a DJI Matrice M600 Pro hexacopter hovering approximately 270 m above the river. At this altitude, the thermal images have a pixel size of approximately 0.38 m but are not geo-referenced. Two types of ROS .bag files are provided in separate zip folders. The first, Baguettes.zip, contains "baguettes" that include 15-second subsets of data with a reduced sampling rate for the GNSS and IMU. The second, FullBags.zip, contains the full set of ROS topics recorded by RiOS but have been subset to include only the time ranges during which the UAS was hovering in place over one of 11 cross sections along the reach. The start times are included in the .bag file names as portable operating system interface (posix) time stamps. To view the data within ROS .bag files, the Foxglove Studio program linked below is freely available and provides a convenient interface. Note that to view the thermal images, the contrast will need to be adjusted to minimum and maximum values around 12,000 to 15,000, though some further refinement of these values might be necessary to enhance the display. To enable geo-referencing of the thermal images in a post-processing mode, another M600 hexacopter equipped with a standard visible camera was deployed along the river to acquire images from which an orthophoto was produced: 20240916_SacramentoRiver_Ortho_5cm.tif. This orthophoto has a spatial resolution of 0.05 m and is in the Universal Transverse Mercator (UTM) coordinate system, Zone 10. To assess the accuracy of the orthophoto, 21 circular aluminum ground control targets visible in both thermal and RGB (red, green, blue) images were placed in the field and their locations surveyed with a Real-Time Kinematic (RTK) GNSS receiver. The coordinates of these control points are provided in the file SacGCPs20240916.csv. Please see the metadata for additional information on the camera, the orthophoto production process, and the RTK GNSS survey. The thermal images were used as input to Particle Image Velocimetry (PIV) algorithms to infer surface flow velocities throughout the reach. To assess the accuracy of the resulting image-derived velocity estimates, field measurements of flow velocity were obtained using a SonTek M9 acoustic Doppler current profiler (ADCP). These data were acquired along a series of 11 cross sections oriented perpendicular to the primary downstream flow direction and spaced approximately 150 m apart. At each cross section, the boat from which the ADCP was deployed made four passes across the channel and the resulting data was then aggregated into mean cross sections using the Velocity Mapping Toolbox (VMT) referenced below (Parsons et al., 2013). The VMT output was further processed as described in the metadata and ultimately led to a single comma delimited text file, SacAdcp20240918.csv, with cross section numbers, spatial coordinates (UTM Zone 10N), cross-stream distances, velocity vector components, and water depths. To assess the sensitivity of thermal image velocimetry to environmental conditions, air and water temperatures were recorded using a pair of Onset HOBO U20 pressure transducer data loggers set to record pressure and temperature. Deploying one data logger in the air and one in the water also provided information on variations in water level during the test flights. The resulting temperature and water level time series are provided in the file HoboDataSummary.csv with a one-minute sampling interval. These data sets were used to develop and test a new framework for mapping flow velocities in river channels in approximately real time using images from an UAS as they are acquired. Prototype code for implementing this approach was developed in MATLAB and is also included in the data release as a zip folder called VelocityMappingCode.zip. Further information on the individual functions (*.m files) included within this folder is available in the metadata file associated with this data release. The code is provided as is and is intended for research purposes only. Users are advised to thoroughly read the metadata file associated with this data release to understand the appropriate use and limitations of the data and code provided herein.

Information on water depth in river channels is important for a number of applications in water resource management but can be difficult to obtain via conventional field methods, particularly over large spatial extents and with the kind of frequency and regularity required to support monitoring programs. Remote sensing methods could provide a viable alternative means of mapping river bathymetry (i.e., water depth). The purpose of this study was to develop and test new, spectrally based techniques for estimating water depth from satellite image data. More specifically, a neural network-based temporal ensembling approach was evaluated in comparison to several other neural network depth retrieval (NNDR) algorithms. These methods are described in a manuscript titled "Neural Network-Based Temporal Ensembling of Water Depth Estimates Derived from SuperDove Images" and the purpose of this data release is to make available the depth maps produced using these techniques. The images used as input were acquired by the SuperDove cubesats comprising the PlanetScope constellation, but the original images cannot be redistributed due to licensing restrictions; the end products derived from these images are provided instead. The large number of cubesats in the PlanetScope constellation allows for frequent temporal coverage and the neural network-based approach takes advantage of this high density time series of information by estimating depth via one of four NNDR methods described in the manuscript: 1. Mean-spec: the images are averaged over time and the resulting mean image is used as input to the NNDR. 2. Mean-depth: a separate NNDR is applied independently to each image in the time series and the resulting time series of depth estimates is averaged to obtain the final depth map. 3. NN-depth: a separate NNDR is applied independently to each image in the time series and the resulting time series of depth estimates is then used as input to a second, ensembling neural network that essentially weights the depth estimates from the individual images so as to optimize the agreement between the image-derived depth estimates and field measurements of water depth used for training; the output from the ensembling neural network serves as the final depth map. 4. Optimal single image: a separate NNDR is applied independently to each image in the time series and only the image that yields the strongest agreement between the image-derived depth estimates and the field measurements of water depth used for training is used as the final depth map. MATLAB (Version 24.1, including the Deep Learning Toolbox) source code for performing this analysis is provided in the function NN_depth_ensembling.m and the figure included on this landing page provides a flow chart illustrating the four different neural network-based depth retrieval methods. As examples of the resulting models, MATLAB *.mat data files containing the best-performing neural network model for each site are provided below, along with a file that lists the PlanetScope image identifiers for the images that were used for each site. To develop and test this new NNDR approach, the method was applied to satellite images from three rivers across the U.S.: the American, Colorado, and Potomac. For each site, field measurements of water depth available through other data releases were used for training and validation. The depth maps produced via each of the four methods described above are provided as GeoTIFF files, with file name suffixes that indicate the method employed: X_mean-spec.tif, X_mean-depth.tif, X_NN-depth.tif, and X-single-image.tif, where X denotes the site name. The spatial resolution of the depth maps is 3 meters and the pixel values within each map are water depth estimates in units of meters.

To develop and test this new NNDR approach, the method was applied to satellite images from the American River near Fair Oaks, CA, acquired in October 2020. Field measurements of water depth available through another data release (Legleiter, C.J., and Harrison, L.R., 2022, Field measurements of water depth from the American River near Fair Oaks, CA, October 19-21, 2020: U.S. Geological Survey data release, https://doi.org/10.5066/P92PNWE5) were used for training and validation. The depth maps produced via each of the four methods described above are provided as GeoTIFF files, with file name suffixes that indicate the method employed: American_mean-spec.tif, American_mean-depth.tif, American_NN-depth.tif, and American-single-image.tif. The spatial resolution of the depth maps is 3 meters and the pixel values within each map are water depth estimates in units of meters.

This Matlab (R) toolbox provides several algorithms to learn a linear mapping from an n-dimensional source space to an m-dimensional target space, such that it makes a classification or clustering model that has been trained in the source space applicable in the target space. The source space model is assumed to be either a vector quantization model (such as learning vector quantizations and variations thereof, neural gas or k-Means) or a (labelled) mixture of Gaussians. The target space may be any vector space, but this toolbox will typically fail if the relationship between source and target space is highly nonlinear. In contrast, this toolbox is particularly effective if the difference between source and target space can be expressed in terms of simple, linear transformations such as rotations and scalings.

Remote sensing methods could provide a viable alternative means of mapping river bathymetry (i.e., water depth). The purpose of this study was to develop and test new, spectrally based techniques for estimating water depth from satellite image data. More specifically, a neural network-based temporal ensembling approach was evaluated in comparison to several other neural network depth retrieval (NNDR) algorithms. These methods are described in a manuscript titled "Neural Network-Based Temporal Ensembling of Water Depth Estimates Derived from SuperDove Images" and the purpose of this data release is to make available the depth maps produced using these techniques. The images used as input were acquired by the SuperDove cubesats comprising the PlanetScope constellation, but the original images cannot be redistributed due to licensing restrictions; the end products derived from these images are provided instead. The large number of cubesats in the PlanetScope constellation allows for frequent temporal coverage and the neural network-based approach takes advantage of this high density time series of information by estimating depth via one of four NNDR methods described in the manuscript: 1. Mean-spec: the images are averaged over time and the resulting mean image is used as input to the NNDR. 2. Mean-depth: a separate NNDR is applied independently to each image in the time series and the resulting time series of depth estimates is averaged to obtain the final depth map. 3. NN-depth: a separate NNDR is applied independently to each image in the time series and the resulting time series of depth estimates is then used as input to a second, ensembling neural network that essentially weights the depth estimates from the individual images so as to optimize the agreement between the image-derived depth estimates and field measurements of water depth used for training; the output from the ensembling neural network serves as the final depth map. 4. Optimal single image: a separate NNDR is applied independently to each image in the time series and only the image that yields the strongest agreement between the image-derived depth estimates and the field measurements of water depth used for training is used as the final depth map. MATLAB (Version 24.1, including the Deep Learning Toolbox) source code for performing this analysis is provided in the function NN_depth_ensembling.m available on the main landing page for the data release of which this is a child item, along with a flow chart illustrating the four different neural network-based depth retrieval methods. To develop and test this new NNDR approach, the method was applied to satellite images from the Colorado River near Lees Ferry, AZ, acquired in March and April of 2021. Field measurements of water depth available through another data release (Legleiter, C.J., Debenedetto, G.P., and Forbes, B.T., 2022, Field measurements of water depth from the Colorado River near Lees Ferry, AZ, March 16-18, 2021: U.S. Geological Survey data release, https://doi.org/10.5066/P9HZL7BZ) were used for training and validation. The depth maps produced via each of the four methods described above are provided as GeoTIFF files, with file name suffixes that indicate the method employed: Colorado_mean-spec.tif, Colorado_mean-depth.tif, Colorado_NN-depth.tif, and Colorado-single-image.tif. In addition, to assess the robustness of the Mean-spec and NN-depth methods to the introduction of a large pulse of sediment by a flood event that occurred partway through the image time series, depth maps from before and after the flood are provided in the files Colorado_Mean-spec_after_flood.tif, Colorado_Mean-spec_before_flood.tif, Colorado_NN-depth_after_flood.tif, and Colorado_NN-depth_before_flood.tif. The spatial resolution of the depth maps is 3 meters and the pixel values within each map are water depth estimates in units of meters.

In the second column the instantaneous effects are neglected both for targets and conditioning. In the third column we set instantaneous effects for some drivers and the respective targets. For example, when the target is 1, instantaneous effects are taken into account for driver 2 (first two rows, right column, parameter idDrivers) and conditioning variable 3 (first row, right column, parameter idOtherLagZero).Example of the parameters required to define the methods for an experiment on 5 variables.

The dataset represents a collection of total viewsheds (cf. Llobera et al. 2010) created for the territory of Bohemia (Czech Republic; ca. 57,000 km²). The total-viewshed calculation was based on the R2 algorithm (see Franklin and Ray 1994) and uses the viewshed function from MATLAB’s Mapping Toolbox that was significantly optimized by the authors for large-scale parallel computations. To reduce the computational time, we calculated single viewsheds using every fourth cell as the observing point (cf. Rášová 2017).

The Digital Terrain Model of the Czech Republic of the 5th Generation (DMR 5G) was used as input for the calculations. Prior to the calculation, the input DEM was cleared of modern landscape elements (e.g. embankments of railways and roads, quarries, etc.; for details see Novák – Pružinec 2022). Eight total visibility models of the territory of Bohemia were constructed using the IT4Innovations research infrastructure (https://www.it4i.cz/). Both the observer and the target heights were set at 1.5 m. The viewsheds differ in two parameters: the visibility radius and the resolution of the input grid. As the basic radius, we have set 0.5 km and the cell size of 5 m; further layers are conceived as multiples of these parameters: 1 km/10 m, 2 km/20 m, 4 km/40 m, 8 km/80 m, 16 km/160 m and 32 km/320 m. The only exception is the model with a radius of 64 km, where we preserved the cell size of the preceding iteration (320 m). In the individual models, the visibility values are indicated in percentages corresponding to the portion of visible cells in the given radius (0–100%; rounded up to the next complete value).

Filenames of individual rasters correspond to the parameters set above. For further details see:

We developed a spectral river energy balance model (FLUVIAL-EB, Bray et al., 2017) to predict energy fluxes and river temperature along a large lowland regulated river and, more specifically, developed a module within the model with the specific aim of quantifying the response of river temperatures to perturbations in atmospheric variables. For clear, flowing water that is usually present below dams, FLUVIAL-EB couples a spectral radiation balance model with turbulent energy fluxes, bed conduction, and a 1D hydraulic model employed over the longitudinal profile of a lowland river whose water depth and velocity vary with distance downstream. The dynamic component of the model accounts for the feedback between spatial and temporal variability in water temperature and changes in the atmospheric fluxes and conduction into or out from the streambed. The predicted water temperature is used to compute the latent, sensible, net longwave, bed conduction, and advective energy flux at every time step. Absorbed shortwave radiation is computed for every wavelength in the solar spectrum, and then integrated across all wavelengths. The continuous component of the model interpolates between measurements at meteorological stations at discrete times. Because the governing differential equation is instantaneous, the input meteorological variables must be available for any values of x and t. From hourly averages of input data, we calculated instantaneous data by generating a cumulative sum, applying a smoothing spline, and then taking the derivative. Doing so allows for a continuous spatial and temporal field of the entire river based on hourly meteorological data and modeled steady-state hydraulic values under bankfull flow conditions, with temporal resolution up to 30 s and spatial resolution of every 100 m along the river. The compressed file of the model folder ('FLUVIAL-EB_BrayDozier_2023.zip') contains approximately 82 Matlab scripts and .mat files that, together, make up the entire FLUVIAL-EB model; all are compatible in Matlab version 2023b. The primary command line function, used to run model simulations, is titled 'riverExplicitSoln.m'. To run the model for the spatial extent on the San Joaquin River, CA, USA, you must install the following Matlab Toolboxes: Computer Vision, Curve Fitting, Database Toolbox, Image Processing Toolbox, Mapping Toolbox, Signal Processing Toolbox, Statistics and Machine Learning Toolbox, and the Raster Reprojection Toolbox (not on Mathworks, written by Jeff Dozier and attached below). For examples of command lines used in model simulations, see 'runmodel_baseline.m'.
