Saddle snowfence grid points, Niwot Ridge LTER, Colorado
Point coverage of Saddle snow fence point grid. 1:500 scale. The Saddle snow fence is a 60-meter long, 2.6-meter high fence erected annually in the fall for manipulating winter snowpack and snow drift along a topoedaphic gradient. The fence was first installed in fall of 1993 and is taken down every summer to avoid influencing summer ambient wind. The fence is oriented along a north-south axis, as prevailing winds on Niwot Ridge come from the west, and delineates shrub and moist meadow communities on the windward (west) side and dry meadow communities on the leeward (east) side. The snowfence grid exists within a 60m x 125m area that contains the snowfence. Of the 146 points in the snowfence grid dataset, 84 are located on the leeward (east) side of the snowfence, 56 are located on the windward (west) side of the snowfence, and 6 are control locations outside of but near the snowfence experiment area. See Fig. 4 in Walker et al. (1999) for graphical depiction of the Saddle snow fence grid, snow fence, and vegetation communities within. Snow depth is measured annually at the snow fence grid points, and the grid has been used for locating experimental plots and instrumentation (e.g. see Walker et al. 1993b, Brooks et al. 1995, Walker et al. 1999). This dataset is part of the Saddle grid geographic information system (GIS). Additional information concerning the Niwot Ridge LTER hierarchical GIS can be found in Walker et al. (1993a).
Saddle grid stake points, Niwot Ridge LTER, Colorado
Point coverage with the GPS data points for each of the 88 Saddle grid points. 1:500 scale. This dataset is part of the Saddle grid geographic information system (GIS). Additional information concerning the Niwot Ridge LTER hierarchical GIS can be found in Walker et al. (1993).
PIE LTER suspended sediments at Law's Point, West Creek, a tidal marsh and creek off the Rowley River, Rowley, MA, during 2016-2017.
Turbidity and calibrated suspended sediment concentration measurements were collected along a shore-normal transect from the channel in West Creek, Rowley, MA extending 24 meters into the marsh interior at Law's Point at the PIE LTER. Data was collected every 15 minutes over two different growing seasons during 2016 and 2017, totaling 9 months.

Point, polygon, or marker? In search of the best geographic entity for mapping Cultural Ecosystem Services using the online PPGIS tool, "My Green Place."
<p>Excel files include the raw database and the processed data that led to the quadrat analyses. The "Matrix_raw data" file includes the raw data as downloaded from the server. This data was cleaned and organized for its posterior use. "Quadrat analyzes "file includes all the quadrat analyses resulting in each research question in the paper except question four. Question 4 can be seen in the file "Water analysis_Blaarmeersen." All excel files come with a "CODE" tab that describes each of the codes used, their meaning, and ways that were calculated where necessary. Two zip files include all the GIS files. The first one includes the GIS files from which "Matrix_raw data" was built from. The second folder includes the resulting maps from the quadrat analyses. In order to visualize them as in the paper, configure the symbology tab at the GIS software in quantile and the categories number, as shown in the paper.</p> <p>The production of the files in the "GIS_Processed data" folder was done via a repetitive line of commands in ArcGIS pro. The same process was followed for each one of the quadrat analysis described in the paper.

Example data map compressed with ISO29500-2 with 3 entry point for ArcGIS, MiraMon and OWS context file.
<p>A simple map consisting of a 1:1 000 000 country boundaries vector file, produced by the FAO (United Nations – FAOStat; geodata.grid.unep.ch/options.php?selectedID=2135) on top of a 5’ digital elevation model raster file (produced by the NOAA and NGDC; geodata.grid.unep.ch/options.php?selectedID=1414). Data has been obtained from the UNEP EDE Data Portal (UNEP 2013). Vector file is a Shapefile (a de facto standard) (ESRI 1998), while the raster file consists of either a raw signed 16-bit data or a long known TIFF file (Adobe 1992, Perkins 1995). Metadata and symbolization files are included. OPC specifies how to explicitly relate different parts using .rels files. These files are XML files with the same name as that of its respective source part, adding “.rels” and placed in a “rels” folder. Each of these files lists the target parts related to its source and the semantics of this relation.</p> <p>OPC can define entry points to the data by listing them in a “.rels” part in the root “rels” folder. In this file, three map files: for the ESRI software a world.mxd map, for the MiraMon software a world.mmm map, and a world.xml map in the form of an atom file following the new Web Service common standard (OGC OWS) context document. A geospatial application reading the package will determine which entry part it better supports to start recovering the data.</p>

Localisation of a real vs. binaural simulated point source -- data
<p>This data set contains stimuli and results from an experiment that compared the localisation of a real point source realised by a loudspeaker to the localisation of a binaural simulation of the same source using head related impulse responses (HRIRs) or binaural room impulse responses (BRIRs). The results are published in [1].</p> <p>The corresponding binaural room scanning (BRS) files for the binaural simulation can be found in the file `brs.zip`, the employed noise stimulus in `stimuli.zip`. The file `results.zip` contains the results of all 11 listeners to the localisation task and the file `results_head_movements.zip` the recoreded head movements the listeners performed during the task. The file analysis.zip` contains average results and a plotting script.</p>
Coloration of a point source in Wave Field Synthesis revisited -- data
<p>This database entry contains stimuli and results from the follow up experiment to [1, 2]. In the experiment different Wave Field Synthesis (WFS) systems synthesising a point source were rated in terms of their perceived coloration compared to a real point source. This was done for different audio material, namely pink noise, speech, and music and different listener positions. The different WFS systems consisted of a circular loudspeaker array with a radius of 3m and a linear loudspeaker array with a length of 3m, but different number of employed loudspeakers. To control for the exact listening position, allow instantaneous switching between listening positions, and allow for very high numbers of loudspeakers in the WFS systems the experiment was performed with binaural synthesis without head tracking.</p> <p>The corresponding binaural room scanning (BRS) files for the binaural simulation can be found in the file `brs.zip`, the employed noise and speech stimuli in `stimuli.zip` (note that we cannot release the employed music stimulus, which was a twelve second clip from the electronic song “Luv deluxe” by “Cinnamon Chasers”). The file `results.zip` contains the results of all 16 listeners and the file analysis.zip` calculated average values and a plotting script.</p> <p>[1] Wierstorf, H., Hohnerlein, C., Spors, S., Raake, A.
