چکیده
In this paper, land subsidence susceptibility was assessed for Shahryar County in Iran using the adaptive neuro-fuzzy inference system (ANFIS) machine learning algorithm. Another aim of present paper to assess if ensembles ANFIS with two meta-heuristic algorithms (imperialist competitive algorithm (ICA) and gray wolf optimization (GWO)) would yield a better prediction performance. A remote sensing synthetic aperture radar (SAR) dataset from 2019 2020 persistent-scatterer SAR interferometry (PS-InSAR) technique were used obtain inventory study area use it training testing models. Resulting PS points divided into parts 70% 30% models, respectively. For analysis, eleven conditioning factors taken account: altitude, slope, aspect, plan curvature, profile topographic wetness index (TWI), distance stream, road, stream density, groundwater drawdown, use/land cover (LULC). frequency ratio (FR) applied correlation occurrence. The power models their generated maps (LSSMs) validated root mean square error (RMSE) value under curve receiver operating characteristic (AUC-ROC) analysis. ROC results showed that ANFIS-ICA had best accuracy (0.932) among (ANFIS-GWO (0.926), (0.908)). work optimizing meta-heuristics considerably improves LSSM although alone an acceptable result.

متن کاملA Procedure to Map Subsidence at the Regional Scale Using the Persistent Scatterer Interferometry (PSI) Technique
In this paper, we present a procedure to map subsidence at the regional scale by means of persistent scatterer interferometry (PSI). Subsidence analysis is usually restricted to plain areas and where the presence of this phenomenon is already known. The proposed procedure allows a fast identification of subsidences in large and hilly-mountainous areas. The test area is the Tuscany region, in Ce...

The potential of differential SAR interferometry for land subsidence monitoring is reported on. The principle of the technique and the approach to be used on a specific case are first presented. Then significant results using SAR data from the ERS satellites for various sites in Germany, Mexico, and Italy, representing fast (mlyear) to slow (mmlyear) deformation velocities, are discussed. The S...
متن کاملA Comparison of Precise Leveling and Persistent Scatterer SAR Interferometry for Building Subsidence Rate Measurement
It is well known that the most accurate method to detect changes of height is the geodetic precise leveling method. Due to the high demand work and time needed for precise leveling alternative methods are studied to obtain high quality height information. Differential SAR interferometry techniques such as the Persistent Scatterer Interferometry (PSI) method are studied to detect millimeter leve...
متن کاملUltrashort-baseline Persistent Scatterer Radar Interferometry for Subsidence Detection
This paper presents an improved approach of multi-temporal interferometric synthetic aperture radar (InSAR) for detecting land subsidence phenomena by using time series of high resolution SAR images. Our algorithm extends the capability of the temporarily coherent point (TCP) InSAR technique proposed previously to detect subsidence even in the case of a small number of SAR images available for ...
