Advances in Remote Sensing and GIS applications in Forest Fire Management From local to global assessments






Preface
The importance of wildfires as a natural or a human-induced phenomenon has gained importance at regional and global levels in the last years. Improved remote sensing and computational capabilities enable the fast processing of large image datasets in real time. As a result, remote sensing and geographic information systems are today, more than ever before, common tools for fire monitoring at local, regional and global levels. However, the gap between research and operational use of remote sensing and GIS still exists.

Engineering rock mechanics

An introduction to the principles 

Preface of the Book
With the title Engineering Rock Mechanics, what is this book about? It is about the discipline, based on mechanics, which is used to design structures built on or in rock masses. These structures, which encompass building foundations, dams, rock slopes, tunnel, caverns, hydroelectric schemes, mines, etc., depend critically on the rock mass properties and the interaction between the rock mass and the engineered structure. As a result, the distinct discipline of engineering rock mechanics has developed. The term ’rock mechanics’ refers to the basic science of mechanics applied to rocks; whilst the term ’rock engineering’ refers to any engineering activity involving rocks.

Map Accuracy Assessment and Area Estimation: A Practical Guide






Introduction

Accurate and consistent information on forest area and forest area change is important given the reporting requirements for countries to access results based payments for REDD+1 . Forest area change
estimates usually provide data on the extent of human activity resulting in emissions (e.g. from deforestation) or removals (e.g. from afforestation), also called activity data (AD). A basic methodological approach to estimate greenhouse gas emissions and removals (IPCC, 2003), is to multiply AD with a coefficient that quantifies emissions per unit ‘activity’ (e.g. tCO2e per ha), also called an emission factor (EF)

Handbook on remote sensing for agricultural statistics


Over View of the Book



Chapter 1 describes the data sets relevant to the integration of remote sensing within agricultural statistics. First, the remote sensing data sources themselves will be addressed. The role of reference data and ancillary data layers, and their use in stratification and aggregation, will also be discussed. A key issue arising recently in data access is the general trend towards open access. Thus, while the major commercial remote sensing missions will be listed for reference, attention will be paid to open-access sources for a number of reasons: (1) to create wider awareness on data sets that are available under free and open licenses;

DIGITAL TERRAIN MODELING Principles and Methodology




Preface of the Book
Terrain models have always appealed to military personnel, planners, landscape architects, civil engineers, as well as other experts in various earth sciences. Originally, terrain models were physical models, made of rubber, plastic, clay, sand, etc. Since the later 1950s, the computer has been introduced into this area and the modeling of terrain surface has since then been carried out numerically or digitally, leading to the current discipline — digital terrain modeling.

CAD and GIS Integration

Preface


The need for CAD/GIS integration arises in many applications. Integration of computer-aided design (CAD) and geospatial information systems (GIS) can reduce many inefficiencies and errors made during design, planning, and execution of a project. 

CAD and GIS 


It can also streamline decision making during operations. Many tasks, in particular engineering tasks in design, construction, and asset management throughout the life-cycle of an infrastructure or a facility, require knowledge of and skills in several interrelated and yet disconnected task-specific software and tools. CAD and GIS were developed separately, with decades of standalone existence. They have traditionally been used in tandem for making crucial decisions in

Remote Sensing and GIS Accuracy Assessment



Preface of the Book

The development of robust accuracy assessment methods for the validation of spatial data represents a difficult challenge for the geospatial science community. The importance and timeliness of this issue are related directly to the dramatic escalation in the development and application of spatial data throughout the latter 20th century. This trend, which is expected to continue, will become increasingly pervasive and continue to revolutionize future decision-making processes.

Groundwater Resource Evaluation

Resource Evaluation, Augmentation, Contamination, Restoration, Modeling and Management

Ground Water

Preface of the Book
Groundwater plays a major role in the livelihood of mankind by providing water for drinking, irrigation and industrial purposes. The rapid population growth in the last three decades all over the globe resulted in exploiting more groundwater. The distribution of groundwater—both in space and time— is more erratic as it depends on the subsurface geological and climatic conditions. In many countries, the decline of water level indicates that the resources are depleted very fast. 

It is, therefore, necessary to assess the available subsurface resource in a more judicious scientific manner and then apply it for evolving optimal utilization purposes. There is an urgent need to have a comprehensive book, which contains the entire spectrum of groundwater assessment and management aspects. I had seen many books, which cover only the specific aspects on groundwater exploration, exploitation, augmentation, pollution and remediation and mathematical modeling but not many books on the integrated aspects of all. It was, therefore, planned to bring a book, which covers the above said aspects by inviting specific topics from various experts of the globe.

Book-Sedimentology and Stratigraphy

Introduction: Sedimentology and Stratigraphy

Sedimentology is the study of the processes of formation, transport and deposition of material that accumulates as sediment in continental and marine environments and eventually forms sedimentary rocks. 
Sedimentology and Stratigraphy

Stratigraphy is the study of rocks to determine the order and timing of events in Earth history: it provides the time frame that allows us to interpret sedimentary rocks in terms of dynamic evolving environments. The stratigraphic record of sedimentary rocks is the fundamental database for understanding the evolution of life, plate tectonics through time and global climate change.

PETROLOGY OF SEDIMENTARY ROCKS





Petrology of Sedimentary Rock




This book emphasizes the properties of sedimentary rocks rather than sedimentary processes. Thus, it focuses on description and discussion of mineralogic and chemical composition, as well as the textures and sedimentary structures that characterize sedimentary rocks.

SECOND EDITION, by Sam Bogs,Jr






Preface of the Book

As indicated in the first edition, this book emphasizes the properties of sedimentary rocks rather than sedimentary processes. Thus, it focuses on description and discussion of mineralogic and chemical composition, as well as the textures and sedimentary structures that characterize sedimentary rocks. 





Further, it discusses application of insights derived from study of rock properties to interpretation of their origin, including provenance (sediment source), depositional environments, and diagenesis. 


Part I of the book deals with basic principles related to the origin, classification and occurrence of sedimentary rocks. Part II describes and discusses the siliciclastic sedimentary rocks such as sandstones. 





Part III describes the carbonate sedimentary rocks (e.g. limestones), and Part IV discusses other chemical sedimentary rocks and carbonaceous sedimentary rocks such as oil shales. The book is aimed at advanced undergraduate and graduate students; however, professional geologists may also find the book useful.

Essential Image Processing and GIS for Remote Sensing





Essential Image Processing and GIS




Overview of the Book

From an applied viewpoint, and mainly for Earth observation, remote sensing is a tool for collecting raster data or images. Remotely sensed images represent an objective record of the spectrum relating to the physical properties and chemical composition of the Earth surface materials. Extracting information from images is, on the other hand, a subjective process. People with differing application foci will derive very different thematic information from the same source image.

Hydrology in Practice

Hydrology in Practice

Third edition , Elizabeth M.Shaw Formerly of the Department of Civil Engineering Imperial College of Science, Technology and Medicine  




Preface to the Third Edition 
In the current critical concern for the well-being of the environment, hydrologists in practice are finding the need for information on many more related topics.
The course contents in universities and other training establishments are developing a wider appreciation of the scope of hydrology and requests for the inclusion of such allied subjects as climatic change, sediment transport and catchment morphometry have been indicated. Without changing the structure of the text, brief introductions to these subjects with accompanying references have been inserted where practicable.
The major revisions have resulted from the technological advances in instrumentation and the philosophical changes in data processing. The original aims in handling hydrological measurements were to automate quality control and analysis with complex statistical programs on large-capacity mainframe computers. With desktop personal microcomputers, linked to field instruments and mainframe, the skilled meteorologist or hydrologist can make experienced subjective judgement on the data from elaborate displays of back-up related information.

Semi-Automatic Classification Plugin for Qgis

Version 5.3.6.1


SCP

Developed by Luca Congedo, the Semi-Automatic Classification Plugin (SCP) is a free open source plugin for QGIS that allows for the semi-automatic classification (also known as supervised classification) of remote sensing images. 

SCP



It provides several tools for the download of free images, the preprocessing, the postprocessing, and the raster calculation (please see What can I do with the SCP ? (page 257)). The overall objective of SCP is to provide a set of intertwined tools for raster processing in order to make an automatic workflow and ease the land cover classification, which could be performed also by people whose main field is not remote sensing.

Imagery and GIS

Best Practices for Extracting Information from Imagery

Introduction 


Why Imagery and GIS? Imagery—it allures and fascinates us; its measurements inform us. It draws us in to explore, analyze, and understand our world.
Imagery and GIS



 First comes the astonishment of its raw beauty—the enormity of a hurricane, the stark glaciers in Greenland, the delicate branching of a redwood’s lidar profile, a jagged edge of a fault line in radar, the vivid greens of the tropics, the determined lines of human impact, the rebirth of Mount Saint Helens’ forests, the jiggly wiggly croplands of Asia and Africa, the lost snows of Kilimanjaro. Each image entices us to discover more, to look again and again. Then we start to ask questions. Why do trees no longer grow here? Can trees grow here again? How much has this city expanded?
