Evaluation of shoreline change using multitemporal satellite images

چکیده

Coastal areas are vulnerable to change because, in this region, many human activities and natural influences change. These can result changes the existing coastline. Moreover, city of Surabaya has a reasonably long This study calculated speed shoreline using remote sensing technology SPOT 6 7 high- resolution satellite imagery from 2015 2019. Calculation is assisted by application Digital Shoreline Analysis System (DSAS) several methods, namely Change Envelope (SCE), Net Movement (NSM), End Point Rate (EPR), Linear Regression (LRR). Based on data processing analysis, longest coastline City was found with length 69.605 km, shortest 2019 65.759 km. The maximum be identified SCE method (956.590 m), NSM (+584.722 EPR (+148.725 m per year), LRR (+154.386 year). Also, an analysis land area during 20152019 period resulted Kalisari Village experiencing most significant accretion 358073.62 m2, while Keputih abrasion 30189.72 m2.

Multivariate Change Detection in Multispectral, Multitemporal Images

This paper introduces a new orthogonal transfonn the multivariate change detection (MeD) transfonn based on an established multivariate statistical technique canonical correlation analysis. The theory for canonical correlation analysis is sketched and modified to be more directly applicable in our context. As opposed to traditional univariate change detection schemes our scheme transforms two s...

Building Extraction and Change Detection in Multitemporal Aerial and Satellite Images in a Joint Stochastic Approach

In this report we introduce a new probabilistic method which integrates building extraction with change detection in remotely sensed image pairs. A global optimization process attempts to find the optimal configuration of buildings, considering the observed data, prior knowledge, and interactions between the neighboring building parts. The accuracy is ensured by a Bayesian object model verifica...
