Structural Interpretation of Lineaments Uses Satellite Images Processing: A Case Study in North-Eastern Tunisia
ABSTRACT
This paper presents a lineament detection method using multi-band remote sensing images. The main objective of this work is to design an automatic image processing tool for lineament mapping from Landsat-7 ETM + satellite data. Five procedures were involved: 1) The Principal Component Analysis; 2) image enhancement using histogram equalization technique 3) directional Sobel filters of the original data; 4) histogram segmentation and 5) binary image generation. The applied methodology was contributed in identifying several known large-scale faults in the Northeast of Tunisia. The statistical and spatial analyses of lineament map indicate a difference of morphological appearance of lineaments in the satellite image. Indeed, all the lineaments present a specific organization. Five groups were classified based on three orientations: NE-SW, E-W and NW-SE. The overlapping of lineament map with the geologic map confirms that these lineaments of diverse directions can be identified and recognized on the field as a fault. The identified lineaments were linked to a deep faults caused by tectonic movements in Tunisia. This study shows the performance of the satellite image processing in the analysis and mapping of the accidents in the northern Atlas.

1. Introduction

Aerial-photography can obtain Geological, structures information and some enigmatic phenomena, which were totally invisible from the field. The satellite images cover wide range of the area in the short period of time. This fact leads to a better knowledge on the earth’s surface studies which become less complicated.

The remote sensing has shown a great promise to the researchers in the geological map ping and earth exploration [1] [2] [3] . Fault detection is an important element in the field of structural, economic and environmental geology [4] [5] . Currently, in remote sensing there are many approaches to identify morphological and structural lineaments. The approaches correspond to the interpretation of the geomorphologic signatures from high-spatial resolution images, such as Landsat 7. In this paper, combined remote sensing applications through the processing of the Landsat-7 Enhance Thematic Mapper Plus (ETM+) and field observation were used to identify the faults and to estimate their directions in North-Eastren Tunsia. All the visible information on the image was interpreted. Geological structures of north-eastern Tunisia were extracted using detectable lineaments analysis on the satellite images. The method of associating the remote sensing with the geological and geo-morphological studies could provide considerable contribution on the lineament detection techniques.

2. Material and Method

2.1. Study Area

North eastern Tunisia was selected as study area (Figure 1).

Geologic Setting of Study Area

The Tunisian Tellian domain and its foreland constitute the eastern pro-longa- tion of the Atlas orogenic belt of North Africa, recording the tectonic history of the central Mediterranean realm [6] - [15] . In this domain, several structures are highlighted such as anticlinal, depocenters and troughs (Figure 2). Five depo-

centers can be defined: Douimis, Jalta, Messeftine, Kechabta and d’El Alia separated by morpho-structural lineaments or sedimentary highs [16] [17] [18] [19] [20] .

The Douimis basin is bounded from the northwest by the major NE-SW Ras El-Korane Thibarfault, from the south by the fold of Ichkeul and from the northeast by the Bechateur and Bizerte folds (Figure 2). It is affected by the NNE-SSW Bou Hadid-Borj El Rhouli lineament. The Kechabta basin is affected by the ENE-WSW to E-W folds and in the EW; this orientation of these folds was linked to the movement NNE-SSW El Alia-Teboursouk major fault (Figure 2). The El Alia basin is bounded from the west by NNE-SSW El Alia-Tebour- souk major fault, (Figure 2) inherited from previous tectonic stages, which controlled sedimentation during the Miocene and Pliocene. In El Alia area, the Triassic evaporites are exposed along a NNE-SSW direction defining the fault trace.

The Messeftine basin is separated from Jalta basin by the NS Messeftine fault and from Kechabta basin by theN30 El Alia-Teboursouk fault. This basin is characterized by N70-N90 folds, which are rooted on the NS Messeftine major fault (Figure 2).

The Jalta basin is limited to the NW by the N30 Ras El-Korane Thibar fault, to the east by the NS Messeftine fault and to the south by the N140E Mateur fault (Figure 2). Anticlines in this study area are represented by;

The anticline of J. Naheli which is a complex anticline having the heart occupied by the Trias. Triassic evaporites crop out along a NNE-SSW direction, defining the fault trace. It is part of plicative structures formed during most of the Atlas compression phase of the upper Tortonian age which is affected the country [21] . The anticline of Jebel Amar is a half dome limited to the north by a NE-SW fault. The heart of this anticline is occupied by the triassic evaporites. The Ariana graben which is a collapsed area it is a part of NW-SE troughs Mio- Pliocene-Quaternary filling characteristics of the foreland of the Alps chain of Tunisia [21] [22] [23] . It is bounded by normal faults trending N140 to N160. The subsidence’s basins characterizing the study area include those of Oued Gueniche in the NW, El Mabtouha plainin the South and Utique plain, Lake of Porto.

2.2. Data

The lineaments’ detection of satellite images can be influenced by some climatic factors, hydraulic factors and the illumination source during data acquisition. In addition, the visual quality of an image depends on the spectral bands, the date when it was taken and the scale [24] . Sensor calibration can affect the geometry of the image. The data was derived from the Landsat 7 ETM + satellite that are the bands diversity provides to the interpreter a wealth of manipulated information (7 spectral bands). The Landsat system is the one that holds the record of the continuous observation of the Earth surface (from a polar orbit). Landsat satellites are mainly used for environmental monitoring, disaster assessment, land use, regional planning, mapping, urban management, petroleum and mineral exploration.

Nowadays, Landsat ETM has 8 bands, from visible (band 1, band 2 and band 3) to near-and mid-infrared (band 4, band 5 and band 7) to the thermal radiation (band 6). The spatial resolution is about 15 meters for the panchromatic band (band 8) and about 10 meters for band 1 to band 5 and band 7. The thermal band (band 6) provides a resolution of 60 meters (Table 1).

The image used in this study was taken on 31 May 2001 at 04: 07 am. Landsat data have the advantage of illustrated out the lineaments clearly due to the low value of the solar angle (=122.1057953 SUN_AZIMUTH and SUN_ELEVATION = 65.0615912), the deletion of restrictive spatial detail and the regional coverage [25] .

The composition of bands 1, 2 and 3 were implemented to illustrate the shades that define the topography and the drainage network that often controll- ed by geological structures.

2.3. Methdology

The availability of multispectral information and image enhancement techniques provide more flexible methods to analyze reliable lineament and fracture traces. The methodology presented in this paper for the identification of lineaments with possible structural origin has been divided into two phases. The first one includes the enhancements facilitating the human interpretation using Laplacian filter and Sobel filter. Their advantages and weaknesses are explained in detail by [26] . Most image processing softwares incorporates this kind of treatment. The second phase of treatment is to extract and trace the lineaments automatically, from the image directly or from a binary image. The operation is more complex and, therefore, the programs able to execute it successfully are very few. In general, the literature suggests different step by step procedures leading to the tracing of lineaments [27] - [33] . These procedures generally involve the detection and edge enhancement or gradients followed by a filter as a means to classify the pixels indicating the presence of lineament pixels and indicating the absence of lineament. Some work focuses specifically on methods for analyzing lineaments cards [34] [35] .

2.3.1. Geometric Correction

The main reasons of deformations while recording images by the sensors are the earth curvature, the altitude variation of soil, at mopheric refraction, measurement systems errors and the movements of the platform. Therefore it is necessary to conduct a geometric correction to bring the image to a planimetric reality. The image was adjusted to the same type of the topographic map projection (UTM zone 32 N for Tunisia) to correct residual image distortions and accurately calibrate it with the corresponding topographic base. The method consists on selecting a set of reference points on the topographic map. The intersections of roads, bridges, rivers and lakes borders were selected as control points. The GCP Works module allows a successive elimination of the points that increase the average positioning error. Finally, some points spread evenly throughout the image were preserved. The screen visualization of the image superimposed on the digital topographic map reveals the quality of the correction operation.

2.3.2. The Principal Component Analysis

The Principal Component Analysis is an effective technique to accentuate a multispectral image for a geological interpretation [36] . It reduces the information contained in several bands, sometimes highly correlated (Thus, the redundancy of information), into a smaller number of components. These typically represent up to 97% of the total variance of the original data set [37] . Sometimes the information in 5 or 6 bands is reduced by the Principal Component Analysis in only 3 components. This analysis allows, among others, to create colored compounds of the first three colored components that make up an excellent product for visual interpretation, increasing the contrast between various objects on the ground. Visual examination of the ETM image allows finding the same lineaments on each of these images. These images are very similar. Principal Component Analysis was used to preserve the maximum information about the lineaments. The Principal Component Analysis is a transformation that provides a reduced number of bands while maintaining the maximum information [38] . The main components were calculated from 6 spectral bands ETM. Statistical calculations were applied to six bands of the satellite are presented in Table 2 and Table 3.

Statistical calculations of Principal Components show that the first three components represent about 99.6% of the total variance of all the six bands (see Table 4). The first three components are then displayed in red, green and blue to create a colored compound which will subsequently be enhanced by linear functions to increase the contrast. The colorful image composed of the three main components is shown in Figure 3. The image obtained using a colored composition of bands 1, 2 and 3 as well as those resulting from Principal Component Analysis will be subsequently used in conjunction with the filtered and binary images for the localization and the lineaments extraction.

2.3.3. Enchantement of Lineaments by Filtering

The purpose of this step is to increase the visibility of lineaments. Various types of filtering are used in remote sensing. Grayscale filtering techniques can be used on remote sensing multispectral image to enhance or extract contours, for homogenize areas disturbed by noise or to manipulate morphology shapes. These are local transformations of images, they operate on neighborhoods points.

1) Spatial Filtering

Spatial filtering is a technique that aims to eliminate the noise contained in the data; noise is defined as any non-useful data that masks information and that came from the acquisition system and external sources such as the atmosphere or the relief. This type of operation indicates discontinuities between textures reflecting the morphostructural features, tectonic or contours.

2) Directional Filter of Sobel

Directional filters enhance the lineaments perception causing an optical shadow effect focused on the image as if it was illuminated by grazing light [39] .

Moreover, these types of filter enhance detecting the lineaments which are not favored by the illumination source [40] . The enhancement of lineaments was therefore made from directional filters using the Sobel operator. In this study the image used for the filtering is the one of the Principal Component Analysis combination. The Sobel filter is a selective variety of directional filters where the values of the convolution matrix are determined according to the distance from the central pixel. In other words, the more central points in the matrix (line or column) are involved greatly than the ones of the extreme parts in directional gradient measure [41] . It has been shown by [42] that the response of the pulse of this filter was relatively independent of the orientation of lineaments. It can detect both the lineaments vertically, horizontally and with a degree of 45˚ with respect to the gradient filter. The size of the filters depends on the needs. Only the lineaments which the size is greater than half of the convolution window are detected [43] . In this study, a filter of 5 by 5 was used (Figure 4). A four derived images were generated (Figure 5) from four directional Sobel filters (NW, EW, SW and NS). This allows to detect lineaments in all possible directions.

2.3.4. Histogram Segmentation

The distribution histograms of the images obtained after directional filtering is in the form of normal curves divided into 2 parts. The first central portion represents the frequency of the pixels associated to homogeneous areas of the satellite image and corresponds to small changes in the gradient of the brightness. The second part, represented by the ends of the distribution corresponds to the frequency of pixels for which the filter has detected a strong transition gray level in the image (presence of lineaments). To identify the preferred orientations in the study area, histograms were created from raw data of filtered images.

Figure 4. Directional filters sobel.

Figure 5. Binary images.

These histograms were enhanced so as to bring the pixels located at the ends of the distribution to the values 0 and 255. A series of tests were performed to determine the cut-off values to define linear features in filtered images. These tests indicated that a 5% cut to the left and right ends of the distribution made it possible to highlight the rough texture of the image and thus better identify lineaments. The corresponding histograms are shown in Figure 6.

Figure 6. Histograms segmentation.

2.3.5. Binary Image Creation

The images obtained after the Sobel filter applications had uniform values which manifested by visually shade of gray. The linéamentaires structures are thus confused in this gray background. Therefore, a “binarization” of images was made to optimize contrast by eliminating the hue and keep only elements detected by the Sobel filters. This approach has also been used by several researchers to highlight the lineaments [37] . The test series showed that the 5% of threshold of the upper and lower section of the gray levels of the histogram represent significant limitations for creating binary image. The binary image is created by assigning the value 0 to the pixels for which the gradient is below the threshold and by assigning the value 255 to the other pixels of image. This gives us an image with two gray levels: Lineaments in black (0) and the background of the image in white (255). The binary images are shown in Figure 5.

3. Results

3.1. Lineaments Mapping

Sudden intensity variations on the Landsat image filtered emphasize the high spatial frequencies and are used to enhance the discontinuities in the images and therefore the mapping of linements.

All kinds of human activities generate an amount of linear phenomena making visual search of geological lineaments very difficult. These linear phenomena act as a noise masking geological information. In order to maintain the objectivity of the process, no confrontation or checks are made with data from classical geology before treatment of four images has been completed. Once the operation is completed, the maps are displayed on a computer screen to confront the lineaments layer with roads layer, with drainage network layer and with geological formations layer. Only visibly lineaments from artificial sources and lineaments of human parts are eliminated.

3.2. The Lineaments Map Analysis

The result of the processing of satellite images is a map showing 3454 lineaments with total length is 1713 km.

3.2.1. Visual Recognition

By Visual analysis of lineaments map (Figure 7), all the lineaments presented an organization that not arbitrary. There are grouped into three directions, one in the NE-SW direction, the other in the direction nearly east-west and one in the NW-SE direction. A check with the geological map confirms that the various lineaments directions are often congruent with faults and lithological contacts.

3.2.2. Lineaments Map Statistics

It is very relevant to divide the geological map in the three directions that were described above. There have, NE-SW alignment of Jebel Sekkak, jebel Kechabta, Jebel Meseftine, El Alia and Raf Raf massif, EW alignment materialized largely by Jebel Amar and Jebel Nahli and finally the NW-SE alignment materialized by

the two boundary faults of the Jalta-Mateur trough. Statistical analysis of lineaments was explored to study the geometry of lineament network and to identify the dominant directions at the regional scale. The synthesis lineaments map (Figure 7) represents all the segments resulting from the superposition of the information contained in the four filtered satellite images. This lineament map appears polymodal, indeed, it reveals three important lineaments direction families, e.g. EW, NE-SW and NW-SE, with dominance of lengths of NE-SW orientation lineaments, followed by the EW accidents lengths and finally the length of NW-SE orientation lineaments.

Statistical analysis of frequencies of directions includes generating a rose diagram of lineaments. This rose was generated by using Oriana software. The rose shows the preferred directions NE-SW, NW-SE and EW (Figure 7), with dominance of the NE-SW direction.

3.2.3. Lineament Density

The study area is characterized by a global low lineament density (Figure 8). The highest densities were observed in the mountains. These values are limited by medium densities. The very lowest densities occupy the troughs and lowlands densely populated. Moderate densities represent small enclaves within low densities. The superposition of the geological map over the map of lineaments density reveals that there is an obvious link between the two. In fact, the high density was reflected by highly fractured zones. The central part of the study area (with the high density), corresponds to NE-SW Teboursouk-El Alia fault corridor witch occupying the central part of the study area. The eastern part of the study area is characterized by a low density materialized by Utique plain and the Ariana graben which are heavily populated. Small enclaves within these plains show high densities. The outcrop constitute, within the study area, an expression factor of lineaments. The density of lineament reveals that the geology and the outcrops are the causes of variability of lineaments.

4. Discussion

To determine the mapping, the analysis and the structural interpretation of the study area, a confrontation of the results with existing geological maps and structural diagrams of the various maps were conducted forming the study field. The global map was produced by the five geological maps assembly, forming the study area shows a great variety on its lithological and structural composition (Figure 2). The overlay of this global map with the satellite data of the study area (Figure 9) provide the access of the number of lineaments identification corresponding to some mapped geological faults. These lineaments derived from these images are often perfectly superimposed or slightly shifted relative to the structural elements of the field or of its prolongation. The offset between the satellite image and geological lineaments can be explained. Geo-coding and re-sampling which causes some imprecision in the image and on the other hand, changing in the scale and projection system.

From these analyzes, some preferred orientations like NE-SW, NW-SE and EW are noticed on the satellite image that shows practically the same original structural lineaments (fault). On the final synthetic lineament’s map, the order of length is variable (hectometric to plurimetric). Their distribution on the image is not homogeneous. Lineaments form frames that are generally oriented NE-SW, forming a major lineament across the center of the study area (Jebel Sekkak, Jebel Kechabta, Jebel Meseftine, El Alia and Raf Raf). This lineament network coincides perfectly with Teboursouk-El Alia master fault. The lineament network affecting Jebel Amar and jebel Nahli, according to the geological map elaborated by [44] represents the major EW accident; this fault is related by a series of secondary accidents that continues until Jebel Nahli after having been under a slight curvature to the West.

5. Conclusions

The pretreatment application techniques enhanced the radiometric images, and it becomes more expressive and more refined from a structural mapping. Several studies [45] showed that Landsat images contribute to the recognition of the discontinuous reservoirs and also to the mapping of major regional accidents. The simple methodological approach based on the use of directional filters (Sobel filter) and histograms segmentation has contributed to the development of a specific lineament map. A statistical analysis of these lineaments using directional diagram rose showed a particular distribution of orientation according to the preferred direction NE-SW followed by these of EW to NW-SE. The confrontation of these results with surface geological data (geological maps) shows that:

1) The lineaments in the satellite images have been identified and recognized in the field as faults.

2) The major part of the identified lineaments across the study area is related to deep faults in relation with large tectonic movements.

These results show the importance of lineament analysis in mapping of accidents in Septentrional Atlas of Tunisia.
