This dataset contains 50-ft contours for the Hot Springs shallowest unit of the Ouachita Mountains aquifer system potentiometric-surface map. The potentiometric-surface shows altitude at which the water level would have risen in tightly-cased wells and represents synoptic conditions during the summer of 2017. Contours were constructed from 59 water-level measurements measured in selected wells (locations in the well point dataset). Major streams and creeks were selected in the study area from the USGS National Hydrography Dataset (U.S. Geological Survey, 2017), and the spring point dataset with 18 spring altitudes calculated from 10-meter digital elevation model (DEM) data (U.S. Geological Survey, 2015; U.S. Geological Survey, 2016). After collecting, processing, and plotting the data, a potentiometric surface was generated using the interpolation method Topo to Raster in ArcMap 10.5 (Esri, 2017a). This tool is specifically designed for the creation of digital elevation models and imposes constraints that ensure a connected drainage structure and a correct representation of the surface from the provided contour data (Esri, 2017a). Once the raster surface was created, 50-ft contour interval were generated using Contour (Spatial Analyst), a spatial analyst tool (available through ArcGIS 3D Analyst toolbox) that creates a line-feature class of contours (isolines) from the raster surface (Esri, 2017b). The Topo to Raster and contouring done by ArcMap 10.5 is a rapid way to interpolate data, but computer programs do not account for hydrologic connections between groundwater and surface water. For this reason, some contours were manually adjusted based on topographical influence, a comparison with the potentiometric surface of Kresse and Hays (2009), and data-point water-level altitudes to more accurately represent the potentiometric surface.

Pockmarks are defined as depressions on the seabed and are usually formed by fluid expulsions. Recently discovered, pockmarks along the Aquitaine slope within the French EEZ, were manually mapped although two semi-automated methods were tested without convincing results. In order to potentially highlight different groups and possibly discriminate the nature of the fluids involved in their formation and evolution, a morphological study was conducted, mainly based on multibeam data and in particular bathymetry from the marine expedition GAZCOGNE1, 2013. Bathymetry and seafloor backscatter data, covering more than 3200 km², were acquired with the Kongsberg EM302 ship-borne multibeam echosounder of the R/V Le Suroît at a speed of ~8 knots, operated at a frequency of 30 kHz and calibrated with ©Sippican shots. Precision of seafloor backscatter amplitude is +/- 1 dB. Multibeam data, processed using Caraibes (©IFREMER), were gridded at 15x15 m and down to 10x10 m cells, for bathymetry and seafloor backscatter, respectively. The present table includes 11 morphological attributes extracted from a Geographical Information System project (Mercator 44°N conserved latitude in WGS84 Datum) and additional parameters related to seafloor backscatter amplitudes. Pockmark occurrence with regards to the different morphological domains is derived from a morphological analysis manually performed and based on GAZCOGNE1 and BOBGEO2 bathymetric datasets. The pockmark area and its perimeter were calculated with the “Calculate Geometry” tool of Arcmap 10.2 (©ESRI) (https://desktop.arcgis.com/en/arcmap/10.3/manage-data/tables/calculating-area-length-and-other-geometric-properties.htm). A first method to calculate pockmark internal depth developed by Gafeira et al. was tested (Gafeira J, Long D, Diaz-Doce D (2012) Semi-automated characterisation of seabed pockmarks in the central North Sea. Near Surface Geophysics 10 (4):303-315, doi:10.3997/1873-0604.2012018). This method is based on the “Fill” function from the Hydrology toolset in Spatial Analyst Toolbox Arcmap 10.2 (©ESRI), (https://pro.arcgis.com/en/pro-app/tool-reference/spatial-analyst/fill.htm) which fills the closed depressions. The difference between filled bathymetry and initial bathymetry produces a raster grid only highlighting filled depressions. Thus, only the maximum filling values which correspond to the internal depths at the apex of the pockmark were extracted. For the second method, the internal pockmark depth was calculated with the difference between minimum and maximum bathymetry within the pockmark. Latitude and longitude of the pockmark centroid, minor and major axis lengths and major axis direction of the pockmarks were calculated inside each depression with the “Zonal Geometry as Table” tool from Spatial Analyst Toolbox in ArcGIS 10.2 (©ESRI) (https://pro.arcgis.com/en/pro-app/tool-reference/spatial-analyst/zonal-statistics.htm). Pockmark elongation was calculated as the ratio between the major and minor axis length. Cell count is the number of cells used inside each pockmark to calculate statistics (https://pro.arcgis.com/en/pro-app/tool-reference/spatial-analyst/zonal-geometry.htm). Cell count and minimum, maximum and mean bathymetry, slope and seafloor backscatter values were calculated within each pockmark with “Zonal Statistics as Table” tool from Spatial Analyst Toolbox in ArcGIS 10.2 (©ESRI). Slope was calculated from bathymetry with “Slope” function from Spatial Analyst Toolbox in ArcGIS 10.2 (©ESRI) and preserves its 15 m grid size (https://pro.arcgis.com/en/pro-app/tool-reference/spatial-analyst/slope.htm). Seafloor backscatter amplitudes (minimum, maximum and mean values) of the surrounding sediments were calculated within a 100 m buffer around the pockmark rim.

Introduction

Geographical scale, in terms of spatial extent, provide a basis for other branches of science. This dataset contains newly proposed geographical and geological GIS boundaries for the Pan-Tibetan Highlands (new proposed name for the High Mountain Asia), based on geological and geomorphological features. This region comprises the Tibetan Plateau and three adjacent mountain regions: the Himalaya, Hengduan Mountains and Mountains of Central Asia, and boundaries are also given for each subregion individually. The dataset will benefit quantitative spatial analysis by providing a well-defined geographical scale for other branches of research, aiding cross-disciplinary comparisons and synthesis, as well as reproducibility of research results.

The dataset comprises three subsets, and we provide three data formats (.shp, .geojson and .kmz) for each of them. Shapefile format (.shp) was generated in ArcGIS Pro, and the other two were converted from shapefile, the conversion steps refer to 'Data processing' section below. The following is a description of the three subsets:

(1) The GIS boundaries we newly defined of the Pan-Tibetan Highlands and its four constituent sub-regions, i.e. the Tibetan Plateau, Himalaya, Hengduan Mountains and the Mountains of Central Asia. All files are placed in the "Pan-Tibetan Highlands (Liu et al._2022)" folder.

(2) We also provide GIS boundaries that were applied by other studies (cited in Fig. 3 of our work) in the folder "Tibetan Plateau and adjacent mountains (Others’ definitions)". If these data is used, please cite the relevent paper accrodingly. In addition, it is worthy to note that the GIS boundaries of Hengduan Mountains (Li et al. 1987a) and Mountains of Central Asia (Foggin et al. 2021) were newly generated in our study using Georeferencing toolbox in ArcGIS Pro.

(3) Geological assemblages and characters of the Pan-Tibetan Highlands, including Cratons and micro-continental blocks (Fig. S1), plus sutures, faults and thrusts (Fig. 4), are placed in the "Pan-Tibetan Highlands (geological files)" folder.

Note: High Mountain Asia: The name ‘High Mountain Asia’ is the only direct synonym of Pan-Tibetan Highlands, but this term is both grammatically awkward and somewhat misleading, and hence the term ‘Pan-Tibetan Highlands’ is here proposed to replace it. Third Pole: The first use of the term ‘Third Pole’ was in reference to the Himalaya by Kurz & Montandon (1933), but the usage was subsequently broadened to the Tibetan Plateau or the whole of the Pan-Tibetan Highlands. The mainstream scientific literature refer the ‘Third Pole’ to the region encompassing the Tibetan Plateau, Himalaya, Hengduan Mountains, Karakoram, Hindu Kush and Pamir. This definition was surpported by geological strcture (Main Pamir Thrust) in the western part, and generally overlaps with the ‘Tibetan Plateau’ sensu lato defined by some previous studies, but is more specific.

More discussion and reference about names please refer to the paper. The figures (Figs. 3, 4, S1) mentioned above were attached in the end of this document.

Data processing

We provide three data formats. Conversion of shapefile data to kmz format was done in ArcGIS Pro. We used the Layer to KML tool in Conversion Toolbox to convert the shapefile to kmz format. Conversion of shapefile data to geojson format was done in R. We read the data using the shapefile function of the raster package, and wrote it as a geojson file using the geojson_write function in the geojsonio package.

This dataset consists of 100-metre-interval contour lines across East Antarctica. The contours are derived from the REMA 2 (Reference Elevation Model of Antarctica version 2) 10-metre mosaic digital elevation model. Features were produced using the ArcGIS Pro 'Generate Topographic Contours' tool with a Raster Smooth Tolerance of 0.6, a Contour Minimum Length of 300 metres, and a Contour Smooth Tolerance of 150 metres based on an output map scale of 1:1 million. Contour generation was limited to a source mosaic tile set extending from the from approximately 31°E to 177°E and from the coast inland to approximately 76°S. The contours were edited to remove holes present in the source DEM and some shorter-length contours were manually removed to improve clarity. This data is stored in the AAD's relief ln enterprise dataset.

Se hace una verificación de la cantidad puntos de calor detectados durante el mes de monitoreo, para corroborar cuales Path Row que cubren la región amazónica (4-57, 4-58, 4-59, 4-60, 4-61, 4-62, 4-63, 9-59, 9-60, 7-58, 7-59, 7-60, 7-61, 5-57, 5-58, 5-59, 5-60, 5-61, 5-62, 3-57, 3-58, 3-59, 8-58, 8-59, 8-60, 6-57, 6-58, 6-59, 6-60, 6-61, 6-62) deben priorizarse para la descarga.Para el procesamiento y clasificación de las imágenes, y los diferentes geoprocesos se usan herramientas del software ArcGis (Esri, 2022a). Con este programa se aplican los “Model Builder” que se han generado para este procesamiento, los cuales hacen parte de los flujos de trabajo (Workflow) construidos en la plataforma SIATAC. Con las imágenes se generan dos composiciones de color RGB , (1) una que integra el Índice de Vegetación de Diferencia Normalizada - NDVI (B5-B4/B5+B4), el Radio Normalizado de Quema-NBR (B5-B7/ (B5+B7) y la banda del infrarrojo cercano -IR (B5); (2) la otra composición se hace con las bandas B7-B5-B2; estas composiciones resaltan las áreas que han sufrido procesos de quema de la vegetación (Murcia & Otavo, 2018).Con la composición RGB (1) se hace una clasificación no supervisada tipo clúster (Clúster Iso) (Esri, 2022b) y se generan 11 clases. Sobre esta capa ráster se hace una verificación visual para determinar cuál de las 11 clases corresponde a las cicatrices, este proceso se hace con respaldo en el protocolo metodológico (Murcia et al., 2018) y las dos composiciones ya generadas. Una vez seleccionada la clase que se ha verificado como cicatrices, se hace una reclasificación binaria de las unidades, en la que uno (1) son cicatrices y cero (0) las otras clases. En el mismo proceso (Model Builder) se hace la vectorización y se genera la capa de polígonos de cicatrices.Luego se hace una verificación visual de los polígonos generados, para descartar aquellos que no son cicatrices, para esto se aplican los criterios previstos en el protocolo metodológico (Murcia et al., 2018) teniendo como referente las dos composiciones previamente generadas. Con la capa resultado se hace un proceso de análisis espacial de intersección (Esri, 2022c) para descartar las cicatrices que ya fueron clasificadas en el mes anterior.A la capa resultante se le hace control de calidad para verificar la exactitud temática, validando aspectos como delimitación, errores por omisión y errores por comisión. De igual modo, se verifica que la capa cumpla con todos los criterios de topología como la correcta adyacencia entre polígonos, y se aprueba la capa.En el siguiente paso, la capa aprobada se integra en un WorkFlow (Esri, 2022d) de la base de datos en la plataforma SIG de Esri, del SIATAC. Luego se aplica un proceso SIG de intersección mediante el cual se clasifican las cicatrices que se ubican en áreas que eran bosques, según la capa de bosques más reciente generada por el IDEAM (Ideam, 2022). Sobre los polígonos restantes, se aplica el mismo proceso SIG (intersección) con la capa de coberturas de la tierra, del periodo más reciente (Sinchi, 2022) y se clasifican las cicatrices que se ubican en donde había vegetación secundaria u otras coberturas, principalmente pastos.La capa resultante se somete a un proceso de análisis espacial de intersección para generar la información de las cicatrices con el tipo de cobertura vegetal afectada, por cada Unidad Espacial de Referencia (UER): Grandes paisajes, Jurisdicción de Corporaciones Autónomas Regionales o de Desarrollo sostenible, Estado legal del territorio, Departamentos y Municipios. Para finalizar, las estadísticas se publican en el portal del Sistema de Información Ambiental Territorial de la Amazonia colombiana -SIATAC (https://siatac.co/cicatrices-de-quema/).BIBLIOGRAFÍAMurcia, U. & Otavo, S.
