4.1. The Line Density tool calculates the magnitude per unit area from line features within the neighborhood around each cell. Results and Discussion A lineament density map was produced (fig. This helps illustrate how people are distributed across the United States using relative density patterns. When creating a dot density map, you specify how many … USA Population Density: description: This web map illustrates the population density in the United States in 2010. Refer to ArcMap: How Line Density works for more information. Based on the results of the extraction and lineament density Lineament density maps help identify permeability in the Libungo geothermal area. Higher values were assigned to more dense areas to define the infiltration index rates raster. The obtained map of the lineament density is shown in Fig.3. software. The lineament density map was established using the Density command in the ArcGIS Spatial Analyst extension. Use the Line Density tool to create a heat map layer on line features using the same concept as the Point Density tool. to produce final lineament map (fig. 4). PCI Geomatica was used to extract lineament and lineament intersection map using the lineament model. The calculation of lineament related values with script files was done using Arc GIS 9.3 software. analysis of lineament density is executed by counting the number of lineaments confined in defined unit area. Population density is calculated by dividing the total population count of geographic feature by the area of the feature, in square miles. (a) Automatically extracted lineaments and rose diagram; (b) Lineament density map by using ArcGIS. Dot density display was produced by county for the United States. The image is processed by using Geomatica 2015 and Arcgis software and produces lineament density map with various groups of value from high to low. Geology of the study area is dominated by volcanic rock with a dominant lineament of trending northwest-southeast and is part of the Great Sumatran Fault in the Semangko segment. The information from the satellite imageries of the study area were presented in form of lineament, lineament intersection, lineament density, lineament intersection density maps and rose diagram showing the distribution of lineaments based on azimuthal lineaments were converted to vector formats in ArcGIS 9.3 environment. The search radius within which to calculate density. Fig. For the current study the density map of the study area is created by using the ‘Line Density’ tool in the spatial analyst toolbox of ArcMap 10.2 software. digitizing using ArcGIS 9.3. These density maps will be used for an analysis of the lineament and well relationship. The lineament/fracture analyses … This indicator enables performing preliminary assessment of massif fracture degree20. 3. ArcGIS 10.2.2 were used to create lineament density and finally Rockworks 17 was used for trend analysis to create rose diagram. The analysis process is as follows. The extracted lineaments were statistically analyzed to determine their lengths, densities and intersections. Units are based on the linear unit of the projection of the output spatial reference. IV. Population density is the number of people per square mile. distributed with equi-spaced grids. 4). The lineament / fracture analyses indicated that the area For example, if the units are in meters—to include all features within a one-mile neighborhood—set the search radius equal to 1609.344 (1 mile = 1609.344 meters). Extracted lineament is processed using ArcGIS software to produce a lineament density map and processed using Rockworks software to generate direction. The raster layer obtained was reclassified into five classes according to the infiltration rates. Density analysis Linear density of lineaments (LL) is calculated as their total length per unit of area. The Line Density tool. The results obtained were used to generate lineament density, lineament intersection map and rose diagram. No county boundaries are displayed. Then rose diagram was generated using Rockworks 15 software to determine lineaments trends. With this data, we can draw the three kinds of lineament density maps including a lineament length density map, a lineament counts density map and a lineament cross-points density map.
