The overall accuracy, calculated from 1, stratified random points is This novel data set can help improving environmental impact assessments of the global mining sector, for example, regarding mining-induced deforestation or fragmentation and degradation of ecosystems.
It can also serve as a benchmark for further monitoring the temporal evolution of mining sites around the world and as training and validation data to support automated classification of mines using satellite images. We produced the global-scale data set on mining areas by visual interpretation of satellite images. This remote sensing technique is precise but also costly and time-intensive.
To make the visual interpretation viable on a global scale, we defined regions of interest ROI based on the SNL Metals and Mining database This was important to reduce the time spent inspecting the satellite images and delineating the mining extents.
Automated post-processing was also applied to check and correct possible invalid polygon geometries 34 , for instance polygons with self-intersections. We defined our ROI as a buffer around the geographical coordinates georeferenced points of active mines reported in the SNL Metals and Mining database The SNL database provides production information on more than 35, mines across the globe.
Among many other variables, SNL reports the approximate geographic coordinates of the extraction sites, from which we selected all mines reporting activity i. This subset added up to 6, mining locations extracting 76 different commodities, with a focus on coal, metal ores and industrial minerals.
Note that many mines, particularly regarding metal ore extraction, report more than one commodity in the SNL database see full list in Table 1. The buffer around the selected SNL mines was necessary to increase the efficiency and systematize the interpretation of the satellite images. The radius of the buffer should be as small as possible and cover all mining ground features, including open cuts, tailings dams, waste rock piles, water ponds, and processing infrastructure.
The polygons were delineated by two trained experts using an open-source web application 35 developed for this specific purpose. The web interface systematically displays buffers and markers with information about the mines.
As background, the app offers three options of satellite layers: Google Satellite, Microsoft Bing Imagery, and Sentinel-2 cloudless These images allow identifying ground features related to mines with high confidence 9. However, these data sources do not cover the whole globe with the same spatial resolution and contain out-of-date images for some regions The Sentinel-2 cloudless provides a mosaic built from Sentinel-2 images taken during the years and Combining these data layers, the experts identified and delineated the ground features related to mining.
All three satellite data sources were visually inspected before delineating the polygons. The majority of the inspected locations had at least two sources of clear images e.
Only very few locations lacked images with sufficient quality to draw the polygons, for example, due to cloud cover or low spatial resolution.
We used the source showing the largest mining extent for the delineation of the areas. This premise was taken because the largest extent of a mine is usually stable for several years as a long lifespan is intended due to economic reasons.
Besides, mining areas generally increase and could only reduce through ecological restoration, which can take a long time These conjectures do not ensure the temporal consistency of all delineated extents but helped to capture the largest and most up-to-date extent of the mines according to the available satellite images within our ROI. In some cases, the mining polygons can also extend beyond the ROI. Mining features intersecting the buffer borders were delineated to account for their full extent, even if they extend beyond the buffer limits.
Moreover, the mining polygons can contain isolated patches with forest or other land covers, which do not necessarily represent any mining feature on the ground.
These patches were included because we aim at accounting for the total area used by mining, including isolated spare areas that most probably cannot have other uses.
The delineated polygons do not distinguish the different ground features within the mines, i. As a final product from the delineation we obtained a set of polygons covering the total land used by mining within the ROI.
We applied geospatial and geometric operations to check and correct the raw data collection. This geoprocessing was performed to avoid double counting of mining areas, correct invalid geometries, and add attributes variables to the polygons. To avoid double-counting, we dissolved polygons that possibly overlapped or shared a common boundary, i.
After that, we removed sliver polygons unwanted small polygons and invalid polygon geometries, producing a consistent set of polygons. From this set of preprocessed polygons, we calculated the area of each feature and added information on the country where each polygon is located. We calculated the area in square kilometers by projecting each polygon to its respective Universal Transverse Mercator UTM zone.
The final set of polygons thus includes the geometries polygons covering the mining areas, their respective areas in square kilometers, country name, and ISO alpha-3 code of the corresponding country. This is useful because many modeling applications require standardized grid data The 30 arcsecond grid was derived from the percentage of area of the geometric intersection between each cell and the geometries of the mining polygons. These percentages were rounded to zero decimal digits to reduce the size of the data set.
Therefore, the percentage of the cell covered by mine should be greater than 0. To obtain the gridded mining area, we estimated the area of each cell in square kilometers and multiplied with the percentage of mining cover per cell, resulting in a 30 arcsecond global grid indicating the mining area within each cell. The 5 arcminute and 30 arcminute grid resolutions were downsampled form the 30 arcsecond grid.
All scripts used in the geoprocessing of data records are available with our open-source web application tool Our data records provide spatially explicit information on the direct land use of mining activities. The main data set consists of 21, mining polygons covering the extents of mining sites worldwide Grid data derived from the polygons is available at 30 arcsecond , 5 arcminute , and 30 arcminute spatial resolution, providing a ready-to-use data set for modeling purposes with the mining area in square kilometers per grid cell.
Figure 1 illustrates how the satellite images were used to delineate the mining extent. In this example, the area is used for coal mining in Mackenzie River, Queensland, Australia. The polygon in Fig. The Sentinel-2 cloudless mosaic is composed by images from the years and 33 while Microsoft Bing Fig.
Nevertheless, all three data sources contributed to providing pieces of evidence of mining in the mapped area. An example polygon delineated over a coal mine in Mackenzie River, Queensland, Australia.
a Shows the delineated polygon in purple and b shows the Sentinel-2 cloudless mosaic composed by images from the year 33 used to delineate the mining extent. c Shows a Microsoft Bing image from July and d a Google Satellite image from December The delineated polygons cover all infrastructure and land cover types directly related to mining activities.
This can produce large polygons, such as in the case of the Salar de Atacama , Chile. Figure 2 shows the delineated polygon extent and a detailed view of one of the mining plants. We decided to map the whole area because the mining plants, in fact, have brine pumping and monitoring wells spreading over the entire salt flat far beyond the actual evaporation ponds Alternative assumptions mapping only the evaporation ponds estimated an area of only However, it is important to note that the case of Salar de Atacama was rather isolated; in most cases, no features such as pipelines and wells outside the main mining sites could be identified from the available satellite images.
Mine on the Salar de Atacama salt flat, Chile. The purple polygon on the left side was derived from the Sentinel-2 images shown in the background. The polygon covers all infrastructure spread over the salt flat, including water pipelines, wells, and the actual mining plants.
The zoom boxes on the right side show Google Satellite images with a detailed view of water pipelines and wells over the salt flat as well as one of the mining plants. In many cases, mines are located following the structure of mineral deposits, making it easy to map them from satellite images. We selected three mines to illustrate these large-scale concentrated activities Fig. The first example Fig. Figure 3b shows the Batu Hijau copper-gold mine. Despite its large open cut, this mine does not use much area for unused material, as its tailings disposal takes place in the ocean The third example is the Super Pit gold mine in Australia, Fig.
This mine is located in one of the largest gold producing regions in the world. In the case of these large mines, coordinates reported in the SNL database were accurate.
Examples of mapped mining polygons with Google Satellite images background. a Carajás iron ore mine in Brazil, b Batu Hijau copper-gold mine in Indonesia, and c Super Pit gold mine in Australia. Contrasting to the above examples, in other regions the reported coordinates were of lower accuracy.
Figure 4 , for example, shows a large area with widely spread coal mining activities in East Kalimantan, Indonesia. The SNL database reports some mining locations in this region, however, they do not always spatially intersect the mining areas mapped from the satellite images.
Coal mining polygons in East Kalimantan, Indonesia, overplayed with the Sentinel-2 Cloudless images form the year provided by EOX Figure 5 shows an overview of the geographical distribution of our mapped mining area across the globe. From this figure we can see concentrations of mining areas in many regions, for example, in northern Chile mainly due to copper extraction and northeastern Australia and East Kalimantan in Indonesia because of coal mining.
The map at the top shows the global distribution of the mapped mining area. The maps at the bottom are zoomed to South America, Australia, and parts of South-East Asia.
These results show that mining areas are highly concentrated in only a few countries. However, it is worth mentioning that our polygons could be biased by the activities reported in the SNL database and could mask countries and commodities that are poorly reported.
For most African countries, however, SNL extraction of metals compares well to the national aggregates. Percentage of mining area mapped per country. Countries have different profiles regarding the spatial distribution of the mines. However, they vary with respect to the number of identified polygons, 5, and 1,, respectively. This discrepancy in the number of mining locations can be related to the high importance of the small-scale mining industry in China 45 , 46 , while Australia is characterized by fewer, large-scale mines Figure 7 displays the relationship between the mapped area and the number of polygons on a country level.
Most of the variation in mining area can be explained by a linear relationship to the number of polygons. A complete summary of the mining area mapped per county is shown in Table 2 and available from download with our data records Relationship between the mapped mining area and the number of features polygons on a country level. The solid line summarizes the relationship between area and number of features for the complete data set, the dashed line excludes China.
Our mining data set accounts for all land cover types related to mining that could be identified from the satellite images. However, it does not distinguish the different features within the polygons.
For example, we could not separate mining from quarry, because this would require additional information other than the satellite images. Although our data set does not cover all existing mines, to date, it is the most comprehensive database on mining extents openly available.
The data set can help filling existing gaps for spatially explicit mineral extraction assessments on a global scale. It opens up opportunities to improve environmental pressure and impact indicators of the mining sector and can support the development of automated systems to monitor mining sites worldwide. The precision of the delineated mining borders can vary according to the satellite data source and the location.
In general, the satellite sources used in this work provide sufficient spatial resolution and georeferencing accuracy to map mining areas 9. Images available from Google Earth, for instance, have an overall positional root mean squared error RMSE of These errors are acceptable for global scale environmental assessments.
The visual interpretation of satellite images depends on the previous knowledge of the perceiving person. The ground features related to mining are not always easy to identify in the satellite images and can be subject to the judgment of the person that delineates a particular mine.
For that reason, we obtained a second independent classification for a set of random points. These validation points were inspected independently by experts that did not participate in the delineation of the mines. They classified these validation points as mine or no-mine based on the three satellite data sources without information whether or not the points were originally mapped as part of a mining areas. The validation points are also part of our data records The overall agreement between the mapped areas and the validation points was In our case the mapped mining areas have An alternative way to visualize the accuracy of our data set is the Receiver Operating Characteristic ROC probability curve.
The graph in Fig. For our classification, the point is near the upper-left corner of the ROC curve, meaning that the classification performs well a perfect classifier would reach the point 0, 1. Besides, the area under the curve AUC in Fig.
Receiver Operating Characteristic ROC derived from 1, random points equally allocated between the mapped classes mine and no-mine. Looking at the spatial distribution of the validation points, we found that half of the points with disagreement i. On the other hand, of the points with an agreement i.
This shows that higher uncertainty lies on the borders of the delineated extents as it can be expected due to the use of several satellite data sources with different precision. These results also indicate that we have high confidence in the existence of mines within the mapped polygons.

Data mining refers to extracting or mining knowledge from large amounts of data. In other words, data mining is the science, art, and technology of discovering large and complex bodies of data in order to discover useful patterns. Theoreticians and practitioners are continually seeking improved techniques to make the process more efficient, cost-effective, and accurate. Any situation can be analyzed in two ways in data mining:.
There are various statistical terms that one should be aware of while dealing with statistics. Some of these are:. This is the analysis of raw data using mathematical formulas, models, and techniques. Through the use of statistical methods, information is extracted from research data, and different ways are available to judge the robustness of research outputs. These techniques are taught in science curriculums. It is necessary to check and test several hypotheses. The hypotheses described above help us assess the validity of our data mining endeavor when attempting to infer any inferences from the data under study.
When using more complex and sophisticated statistical estimators and tests, these issues become more pronounced. For extracting knowledge from databases containing different types of observations, a variety of statistical methods are available in Data Mining and some of these are:. The first step in creating good statistics is having good data that was derived with an aim in mind. There are two main types of data: an input independent or predictor variable, which we control or are able to measure, and an output dependent or response variable which is observed.
