Anechoic McVAMPIRE – Anechoic Multichannel Varying Mouth Position Impulse Response Dataset
<p>This dataset contains impulse responses (IRs) that were recorded in an anechoic room. The recording setup imitates the geometry of a minivan with eight seats arranged in three seat rows. The IRs were captured with 14 overhead microphones positioned in the imaginary car roof using a built-in mouth simulator of a head and torso simulator (HATS) at eight passenger seat positions with eleven orientations each. In addition, the dataset contains IRs measured with four lateral loudspeakers imitating door loudspeakers, as well as a noise floor recording.</p> <p>This dataset supplements the <a href="https://doi.org/10.5281/zenodo.12806684">In-Car McVAMPIRE</a> dataset which was captured with an identical microphone setup in a real car. Both datasets can be used to simulate speech in a car from different seats with different speaker orientations including the loudspeaker-enclosure-microphone (LEM) system under anechoic or realistic, reverberant conditions.</p>
WLAN (WiFi) RSS database for fingerprinting positioning
<p>This data set contains two WLAN Received Signal Strengths (RSS) databases suitable for fingerprinting positioning. One database contains training data (Training_rss.csv, Training_coordinates.csv), the radio map, the second database contains test data (Test_rss.csv, Test_coordinates.csv), RSS measurements on a path and the coordinates of that path. The data was collected in a three-floor building at Tampere University of Technology.</p> <p>The files Training_rss.csv and Test_rss.csv represent a matrix, with a reference point per row and an access point per column. The radio map consists of 446 reference points and 489 access points. Empty RSS values are set to 100. The files Training_coordinates.csv and Test_coordinates.csv contain the reference positions, 3D coordinates in a metric local reference frame. The data format allows to use previously published software (https://doi.org/10.5281/zenodo.889797) to analyze the data.<br> <br> The data is postprocessed: The reference positions of each floor are mapped onto a regular grid with 5 meter grid point spacing and the RSS values at each reference position are spatial averages of the RSS values in the resulting cells. The test data is mapped as well, but to a grid of 1 meter grid point spacing, from which only every third value was selected.</p> <p> </p>
Kinematically collected reference fingerprint map (RFM) with the high precision tracking system for feature-based indoor positioning
<p>The offline referencing phase, one of the core phases of the fingerprinting-based indoor positioning system (FIPS), is the key stage for deploying the positioning system. The reference fingerprint map (RFM) is acquired for representing the relationship between location-relevant features and the corresponding locations and used for inferring the user’s location at the online stage. The kinematically collecting the RFM using the mobile device with the help of high precision tracking system is contributed to the community for benchmarking comparison of the indoor positioning performance. The detailed description of the data is cooming soon.<br> </p>

Tree inventory data such as tree identity, position in the plot, height, architecture and biomass on Mt. Kilimanjaro
<p>This dataset describes position and sizes of all trees above 10 cm diameter at breast height in all plots, also fruiting and flowering events and if it is a canopy tree or not in KiLi project. -999999 represents NA in numeric variables. </p> <p>Within each plot, all trees wider than 10 cm diameter at breast height (dbh) were marked with aluminium tags and their dbh and height were measured. The dbh was measured with a diameter tape (Forestry Suppliers, USA) at 1.3 m for normally shaped trees and 20 cm below or above when branches or irregular shapes impeded measurement at that height. The 1.3 m height was measured from the highest ground level around the stem to standardize measurements taken on slopes. For trees which were strongly buttressed or too big to measure by hand, a laser dendrometer (Criterion RD 1000 with TruPulse 200/200, Centennial, USA) was used to measure the tree above the buttresses and at 1.3 m. Lianas above 10 cm in diameter were also marked and their dbh was measured. Tree height was measured using an ultra-sonic hypsometer (Vertex IV Hypsometer, Haglöf, Langsele, Sweden) or a laser rangefinder (TruPulse 200/200). The tree inventories were carried out between December 2010 and March 2013.</p> <p>The KiLi project (2010-2018) is a German Science Foundation (DFG) funded research unit (DFG research unit FOR1246) that focuses on biodiversity and ecosystem processes along altitudinal and disturbance gradients on Mt. Kilimanjaro (Tanzania, Africa), capitalizing on its world-wide unique range of climatic and vegetation zones. The research unit comprises 2 central projects and 7 subprojects from various disciplines. On a total of 60 study sites in both natural and human-disturbed ecosystems biodiversity (e.g. plants, soil arthropods, ants, bees, frogs, lizards, bats, birds), related ecosystem processes (decomposition, seed dispersal, pollination, herbivory, predation), and biogeochemical processes and properties of ecosystems (climate, soil properties and nutrient status, regulation of water and carbon fluxes, trace gas emissions, primary productivity, functional diversity) are analyzed.</p>
Width-averaged terminus position of Helheim Glacier, 2002-2019
<p>Terminus position of Helheim Glacier (2002-2019) in terms of a width-averaged distance [km] from an upstream flux gate. Positions are identified from satellite imagery---primarily Moderate Imaging Spectroradiometer (MODIS) imagery, but incorporating Landsat and Sentinel-2 imagery when available. Terminus positions are derived manually until 2010 (Schild & Hamilton, 2013) and using a semi-automated technique thereafter (Foga, Stearns & van der Veen, 2014). </p>
Dataset: Time-dependent source apportionment of submicron organic aerosol for a rural site in an alpine valley using a rolling positive matrix factorisation (PMF) window
<p>Uploaded igor pxp files are the data to generate all figures of the results from our publication in Atmospheric Chemistry and Physics with the name of <em>"Time dependent source apportionment of submicron organic aerosol for a rural site in an alpine valley using a rolling PMF window"</em> by Chen et al. (2021).</p> <p>This study deployed a novel and advanced source apportionment technique on a dataset measured in Magadino. Rolling PMF allows retrieving more realistic, time-dependent and detailed information of the organic aerosol sources. This work highlights the strength of the rolling PMF mechanism by comparing it with the results derived from conventional seasonal PMF. Overall, this comprehensive interpretation of chemical speciation monitor (ACSM) data could be a role model for similar analyses.</p>

Parameterized Tree Positions Dresden 2017
<p>The parameterized tree positions represent the location of all trees detected on the basis of a laser scan survey from 2017 within the City of Dresden (Germany). Geometric attributes such as tree height and crown diameter were derived for each tree. For this purpose, the urban forest was classified in the point cloud and then individual tree crowns were segmented. Based on these segments, geometric attributes were determined from the LiDAR point cloud.</p> <p>In total, this automated inventory contains ~ 3 million tree positions. This is an overestimation of the actual number of trees which is due to inaccuracies in the segmentation of individual trees, especially in dense tree stands. Despite this overestimation, the tree volumes detected in the point cloud are realistically reproduced. The methodology is described in detail in <a href="https://doi.org/10.1016/j.ufug.2022.127637">this article</a>.</p> <p>Each tree has the following attributes:</p> <ul> <li>"treeID_utm33_tiles" - ID</li> <li>"H_Tree" – tree height (m) </li> <li>"H_Crown" – crown height (m)</li> <li>"H_Trunk" – trunk height (m)</li> <li>"D_Crown" – crown diameter (m)</li> <li>"X", "Y","Z" – position</li> </ul> <p>The dataset is available either as a Shapefile or GeoJSON in the coordinate system ETRS89/UTM zone 33 (EPSG: 25833).<br> The dataset was divided into tiles.

The approach chosen to offer a viable and reliable solution for this application is based on the use of the well-known advantages of the GNSS system as the main driver for enhancing the accuracy of positioning. For this purpose, the data reported in this work are captured through a GNSS receiver operating over multiple frequency bands (L1, L2, L5) and combining signals from different constellations of navigation satellites (GPS, Galileo, and GLONASS), and they are processed through the precise point positioning (PPP) and real-time kinematic (RTK) techniques. Furthermore, aiming to improve global positioning, the processing unit fuses the results obtained with the data acquired through an inertial measurement unit (IMU), reaching final accuracy of a few centimeters. To validate the system designed and developed in this proposal, three different sets of tests were carried out in a (i) rotary table at the laboratory, (ii) GNSS simulator, and (iii) real conditions in an oceanic buoy at sea. The real-time positioning solution was compared to solutions obtained by post-processing techniques in these three scenarios and similar results were satisfactorily achieved. </pre>

UWB Positioning and Tracking Data Set
<p><strong># UWB Positioning and Tracking Data Set</strong></p> <p>UWB positioning data set contains measurements from four different indoor environments. The data set contains measurements that can be used for range-based positioning evaluation in different indoor environments.</p> <p> </p> <p><strong># Measurement system</strong></p> <p>The measurements were made using 9 DW1000 UWB transceivers (DWM1000 modules) connected to the networked RaspberryPi computer using in-house radio board SNPN_UWB. 8 nodes were used as positioning anchor nodes with fixed locations in individual indoor environment and one node was used as a mobile positioning tag.</p> <p>Each UWB node is designed arround the RaspberryPi computer and are wirelessly connected to the measurement controller (e.g. laptop) using Wi-Fi and MQTT communication technologies.</p> <p>All tag positions were generated beforehand to as closelly resemble the human walking path as possible. All walking path points are equally spaced to represent the equidistand samples of a walking path in a time-domain. The sampled walking path (measurement TAG positions) are included in a downloadable data set file under downloads section.</p> <p> </p> <p><strong># Folder structure</strong></p> <p>Folder structure is represented below this text. Folder contains four subfolders named by the indoor environments measured during the measurement campaign and a folder raw_data where raw measurement data is saved. Each environment folder has a anchors.csv file with anchor names and locations, .json file data.json with measurements, file walking_path.csv file with tag positions and subfolder floorplan with floorplan.dxf (AutoCAD format), floorplan.png and floorplan_track.jpg.</p> <p>Subfolder raw_data contains raw data in subfolders named by the four indor environments where the measurements were taken. Each location subfolder contains a subfolder data where data from each tag position from the walking_path.csv is collected in a separate folder. There is exactly the same number of folders in data folder as is the number of measurement points in the walking_path.csv. Each measurement subfolder contains 48 .csv files named by communication channel and anchor used for those measurements. For example: ch1_A1.csv contains all measurements at selected tag location with anchor A1 on UWB channel ch1. The location folder contains also anchors.csv and walking_path.csv files which are identical to the files mentioned previously.</p> <p>The last folder in the data set is the technical_validation folder, where results of technical validation of the data set are collected. They are separated into 8 subfolders:</p> <p>- cir_min_max_mean</p> <p>- los_nlos</p> <p>- positioning_wls</p> <p>- range</p> <p>- range_error</p> <p>- range_error_A6</p> <p>- range_error_histograms</p> <p>- rss</p> <p> </p> <p>The organization of the data set is the following:</p> <p>data_set</p> <p>+ location0</p> <p>- anchors.csv</p> <p>- data.json</p> <p>- walking_path.csv</p> <p>+ floorplan</p> <p>- floorplan.dxf</p> <p>- floorplan.png</p> <p>- floorplan_track.jpg</p> <p>- walking_path.csv</p> <p>+ location1</p> <p>- ...</p> <p>+ location2</p> <p>- ...</p> <p>+ location3</p> <p>- ...</p> <p>+ raw_data</p> <p>+ location0</p> <p>+ data</p> <p>+ 1.07_9.37_1.2</p> <p>- ch1_A1.csv</p> <p>- ch7_A8.csv</p> <p>- ...</p> <p>+ 1.37_9.34_1.2</p> <p>- ...</p> <p>+ ...</p> <p>+ location1</p> <p>+ ...</p> <p>+ location2</p> <p>+ ...</p> <p>+ location3</p> <p>+ ...</p> <p>+ technical validation</p> <p>+ cir_min_max_mean</p> <p>+ positioning_wls</p> <p>+ range</p> <p>+ range_error</p> <p>+ range_error_histograms</p> <p>+ rss</p> <p>- LICENSE</p> <p>- README</p> <p> </p> <p><strong># Data format</strong></p> <p>Raw measurements are saved in .csv files. Each file starts with a header, where first line represents the version of the file and the second line represents the data column names. The column names have a missing column name. Actual column names included in the .csv files are:</p> <p> </p> <p>TAG_ID</p> <p>ANCHOR_ID</p> <p>X_TAG</p> <p>Y_TAG</p> <p>Z_TAG</p> <p>X_ANCHOR</p> <p>Y_ANCHOR</p> <p>Z_ANCHOR</p> <p>NLOS</p> <p>RANGE</p> <p>FP_INDEX</p> <p>RSS</p> <p>RSS_FP</p> <p>FP_POINT1</p> <p>FP_POINT2</p> <p>FP_POINT3</p> <p>STDEV_NOISE</p> <p>CIR_POWER</p> <p>MAX_NOISE</p> <p>RXPACC</p> <p>CHANNEL_NUMBER</p> <p>FRAME_LENGTH</p> <p>PREAMBLE_LENGTH</p> <p>BITRATE</p> <p>PRFR</p> <p>PREAMBLE_CODE</p> <p>CIR (starts with this column; all columns until the end of the line represent the channel impulse response)</p> <p> </p> <p><strong># Availability of CODE</strong></p> <p>Code for data analysis and preprocessing of all data available in this data set is published on GitHub:</p> <p>https://github.com/KlemenBr/uwb_positioning.git</p> <p>The code is licensed under the Apache License 2.0.</p> <p> </p> <p><strong># Authors and License</strong></p> <p>Author of data set in this repository is Klemen Bregar, klemen.bregar@ijs.si.</p> <p>This work is licensed under a Creative Commons Attribution 4.0 International License.</p> <p> </p> <p><strong># Funding</strong></p> <p>The research leading to the data collection has been partially funded from the European Horizon 2020 Programme project eWINE under grant agreement No. 688116, the Slovenian Research Agency under Grant numbers P2-0016, J2-2507 and bilateral project with Grant number BI-ME/21-22-007.</p> <p> </p>
