drought monitoring and management using remote sensingveerendra manduri
Monitoring drought and its management became easier with the help of remote sensing..several drought monitoring indices can be used to monitor drought condition. this ppt consists of information regarding droughts in relation to agriculture and their monitoring with the help of remotely sense based indices.
There are many different means of investigating the landslide-prone areas. Two types of landslide hazard evaluation methods are available. One is the direct observation and the other one is the use of technological tools. One of the guiding principles of geology is that the past is the key to the future. In evaluating landslide hazards, the future slope failures could occur as a result of the same geologic, geomorphic, and hydrologic situations that led to past and present failures. Based on this assumption, it is possible to estimate the types, frequency of occurrence, extent, and consequences of slope failures that may occur in the future. A landslide susceptibility map goes beyond an inventory map and depicts areas that have the potential for landsliding.
it is highly useful for geography students in the field of remote sensing and it is in very simple and explanatory for the purpose of simplification with relevant images in this ppt.

DELINEATION OF LANDSLIDE AREA USING SAR INTERFEROMETRY AND D-INSAR :A CASE ST...SUJAN GHIMIRE
Surface displacement refers to the movement of the Earth's surface, either vertically or horizontally, due to natural or human-induced factors (Tomás et al., 2014). It can lead to a wide range of hazards such as landslides, earthquakes, and subsidence, which can cause significant damage to infrastructure and property, as well as threaten human lives.The results of this study contribute to a comprehensive understanding of surface displacement dynamics in the district. The integration of D-InSAR and SAR imagery analysis enables the identification of high-risk areas prone to hazards. This information is crucial for local authorities and disaster management agencies in developing effective early warning systems and implementing appropriate mitigation measures.
The findings of this study provide valuable insights into surface displacement in the Sindhupalchowk district using SAR imagery and D-InSAR techniques. The combination of these advanced remote sensing tools offers a powerful approach for monitoring geohazards and mitigating risks. The outcomes of this research can aid in land-use planning, infrastructure development, and disaster risk reduction strategies, ultimately contributing to the safety and well-being of the local population.
Identification Of Ground Water Potential Zones In Tamil Nadu By Remote Sensin...IJERA Editor
A case study was conducted to find out the groundwater potential zones in Salem, Erode and Namakkal districts, Tamil Nadu, India with an aerial extent of 360.60 km2. The thematic maps such as geology, geomorphology, soil hydrological group, land use / land cover and drainage map were prepared for the study area. The Digital Elevation Model (DEM) has been generated from the 10 m interval contour lines (which is derived from SOI, Toposheet 1:25000 scale) and obtained the slope (%) of the study area. The groundwater potential zones were obtained by overlaying all the thematic maps in terms of weighted overlay methods using the spatial analysis tool in Arc GIS 9.3. During weighted overlay analysis, the ranking has been given for each individual parameter of each thematic map and weights were assigned according to the influence such as soil −25%, geomorphology − 25%, land use/land cover −25%, slope − 15%, lineament − 5% and drainage / streams − 5% and find out the potential zones in terms of good, moderate and poor zones with the area of 49.70 km2, 261.61 km2 and 46.04 km2 respectively. The potential zone wise study area was overlaid with village boundary map and the village wise groundwater potential zones with three categories such as good, moderate and poor zones were obtained. This GIS based output result was validated by conducting field survey by randomly selecting wells in different villages using GPS instruments. The coordinates of each well location were obtained by GPS and plotted in the GIS platform and it was clearly shown that the well coordinates were exactly seated with the classified zones.
Landslide assessment using interferometric synthetic aperture radar in Pacit...IJECEIAES
Landslides are a common type of disaster in Indonesia, especially in steepslope areas. The landslide process can be well understood by measuring the surface deformation. Currently, there are no practical solutions for measuring surface deformation at landslide locations other than field surveys in the Pacitan Regency. We apply LiCSBAS, to identify surface deformation in several landslide locations in a specific non-urban area with mixed topographical features. LiCSBAS is a module that utilizes data from the project of looking inside the continent from space (LiCS), using the new small baseline area subset (NSBAS) method. This study utilizes the leaf area index (LAI) to validate the ability of LiCSBAS to detect surface deformation values at landslide locations. The study succeeded in identifying surface deformations at 100 landslide locations, with deformation values ranging from 15.1 to 10.9 millimeters per year. Most of the landslide locations are closely related to volcanic rocks and volcanic sediments on slopes of 30–35°. The NSBAS method in the LiCSBAS module can reduce gaps error in the sentinel-1 image network. However, the utilization of the C-band at a pixel size of 100 meters made surface deformation only well detectable in a large open landslide area.
A Survey on Landslide Susceptibility Mapping Using Soft Computing Techniquesiosrjce
Landslide is a common phenomenon especially in tectonically fragile and sensitive mountainous
terrain which causes damage to both human lives and environment. The complex geological setting of the areas
in the mountainous region makes the land highly susceptible to landslides. Hence, landslide susceptibility
mapping is an important step towards landslide hazard and risk management. The accurate prediction of the
occurrence of the landslide is difficult and in the recent years various models for landslide susceptibility
mapping has been presented. GIS is a key factor for the modeling of landslide susceptibility maps. This paper
presents the review of ongoing research on various landslide susceptibility mapping techniques in the recent
years.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. INTRODUCTION
Landslide is the movement of earth, mass of rock or debris
along the slope
Gharwal Himalaya is a part of extra peninsula
Structural disturbances like folding, faulting, and shearing
are very common in this region
This area exhibits variety of landslides because of various
natural as well as artificial activities
2
3. INTRODUCTION
Landslides may be ignored if they occur in the area of
no human interest
But if it occur in areas like roads, agricultural lands,
human inhabited areas then it leads to loss of life and
property
Minor to major landslides that are very common near
Pipalkoti area on the road of Chamoli to Joshimath
that have increased the maintenance cost of Rishikesh
–Mana Highway
