What is image classification? Image classification refers to the task of extracting information classes from a multiband raster image. The resulting raster from image classification can be used to create thematic maps. Depending on the interaction between the analyst and the computer during classifi...

He is doing amazing! Just watch this great tutorial!
Very clear and comprehensive understanding. Simplified as well.

Kernels can be viewed as shallow in that learning is only applied in a single (output) layer. Recent successes with deeper networks highlight the need to consider richer function classes. The talk will review and discuss methods that have been developed to enable richer kernel classes to be learned....

Exploring Google Earth Engine Platform for Big Data Processing: Classification of Multi-Temporal Satellite Imagery for Crop Mapping

Many applied problems arising in agricultural monitoring and food security require reliable crop maps at national or global scale.

Hey Guys,
Another interesting paper has been published in European Remote Sensing Journal latest issue
Object-based water body extraction model using Sentinel-2 satellite imagery
Water body extraction is an important part of water resource management and has been the topic of a number of research works related to remote sensing for over two decades. Extracting water bodies from satellite images with a pixel-based method or indexes cannot eliminate other objects that have a low albedo, such as shadows and built-up areas.
Thanks for this interesting study Gorde Daniela Kaplan Uğur Avdan

A new MOOC on Ecosystem Services produced by the University of Geneva, the Geneva Water Hub, the Luc Hoffmann Institute, and the Natural Capital Project is now available.
This MOOC is for anybody interested in mastering the strengths and weaknesses of the Ecosystem Services concept as a tool for promoting sustainable development. Subjects covered are both technical (methods for valuation, data acquisition, etc.) and socio-political (how to mainstream the process, ethics, criticism of the method, etc.). Watch an introductory video (3min) to get a feel for the course content and philosophy.
Learners will hear from many of the field’s leading minds. The course is taught by three primary instructors and by 29 guest instructors and interviewees coming from many of the key institutions (the Natural Capital Project, WWF, IUCN, IPBES, TEEB, Luc Hoffmann Institute) and Universities. Learners can expect to hear multiple contrasting opinions. See the full syllabus and list of instructors on the course page.
This course is offered “on-demand”. In practice, class cohorts are formed on a regular basis and you can take as much time as necessary to complete the course (2-5 hours for 5 weeks is a rough estimate). The first cohort begins February 2nd 2017 and once per month thereafter.
Access to all course materials and exams is free.
To obtain a certificate of completion costs 49 USD. Financial aid is available (see FAQs on bottom of the course page).

Effect of Training Class Label Noise on Classification Performances for Land Cover Mapping with Satellite Image Time Series
Supervised classification systems used for land cover mapping require accurate reference databases. These reference data come generally from different sources such as field measurements, thematic maps, or aerial photographs. Due to misregistration, update delay, or land cover complexity, they may contain class label noise, i.e., a wrong label assignment. This study aims at evaluating the impact of mislabeled training data on classification performances for land cover mapping. Particularly, it addresses the random and systematic label noise problem for the classification of high resolution satellite image time series. Experiments are carried out on synthetic and real datasets with two traditional classifiers: Support Vector Machines (SVM) and Random Forests (RF). A synthetic dataset has been designed for this study, simulating vegetation profiles over one year. The real dataset is composed of Landsat-8 and SPOT-4 images acquired during one year in the south of France. The results show that both classifiers are little influenced for low random noise levels up to 25%–30%, but their performances drop down for higher noise levels. Different classification configurations are tested by increasing the number of classes, using different input feature vectors, and changing the number of training instances. Algorithm complexities are also analyzed. The RF classifier achieves high robustness to random and systematic label noise for all the tested configurations; whereas the SVM classifier is more sensitive to the kernel choice and to the input feature vectors. Finally, this work reveals that the cross-validation procedure is impacted by the presence of class label noise.


Remote sensing platforms and sensors: A survey
The objective of this article is to review the state-of-the-art remote sensing technologies, including platforms and sensors, the topics representing the primary research interest in the ISPRS Technical Commission I activities. Due to ever advancing technologies, the remote sensing field is experiencing unprecedented developments recently, fueled by sensor advancements and continuously increasing information infrastructure. The scope and performance potential of sensors in terms of spatial, spectral and temporal sensing abilities have expanded far beyond the traditional boundaries of remote sensing, resulting in significantly better observation capabilities. First, platform developments are reviewed with the main focus on emerging new remote sensing satellite constellations and UAS (Unmanned Aerial System) platforms. Next, sensor georeferencing and supporting navigation infrastructure, an enabling technology for remote sensing, are discussed. Finally, we group sensors based on their spatial, spectral and temporal characteristics, and classify them by their platform deployment competencies. In addition, we identify current trends, including the convergence between the remote sensing and navigation field, and the emergence of cooperative sensing, and the potential of crowdsensing.

A State-of-the-Art Review on the Integration of Building Information Modeling (BIM) and Geographic Information System (GIS)
The integration of Building Information Modeling (BIM) and Geographic Information System (GIS) has been identified as a promising but challenging topic to transform information towards the generation of knowledge and intelligence. Achievement of integrating these two concepts and enabling technologies will have a significant impact on solving problems in the civil, building and infrastructure sectors. However, since GIS and BIM were originally developed for different purposes, numerous challenges are being encountered for the integration. To better understand these two different domains, this paper reviews the development and dissimilarities of GIS and BIM, the existing integration methods, and investigates their potential in various applications. This study shows that the integration methods are developed for various reasons and aim to solve different problems. The parameters influencing the choice can be summarized and named as “EEEF” criteria: effectiveness, extensibility, effort, and flexibility. Compared with other methods, semantic web technologies provide a promising and generalized integration solution. However, the biggest challenges of this method are the large efforts required at early stage and the isolated development of ontologies within one particular domain. The isolation problem also applies to other methods. Therefore, openness is the key of the success of BIM and GIS integration.
