GIS and Natural Resource Management
Principles of remote sensing: an introductory textbook. Tempfli, G. Huurneman, W. Bakker, L. Janssen, et al. Fourth edition. Fundamentals of remote sensing.
Principles of remote sensing. Centre for Remote Imaging, Sensing and Processing. National University of Singapore. Our global forest cover change estimates based on MODIS data and stratified sampling of Landsat images were published in After the opening of the Landsat archive in , UMD developed a system for automatic data processing and classification at national scale.
The outputs of our data processing system are multi-temporal metrics that are similar to what we derived from MODIS, but at 30 m spatial resolution. Paper describing the general Landsat-based data processing and characterization algorithm and its comparison with other approaches:. The image classification and change detection are based on decision tree algorithm. Here are some papers describing this algorithm and its use for image classification:.
Data processing and analysis system to map forest cover change globally from to The results were published in Science in Global forest maps are available on-line:. Results also available through Global Forest Watch data portal:. The global forest cover change map shows all types of tree cover dynamics within primary forests, secondary forests, tree plantations.
For deforestation assessment and forest conservation analysis, it is important to know the area of primary forest loss and degradation. Such analyses were performed for Indonesia and Central Africa:. Precise estimation of forest cover change map uncertainty is important for further use of change area to estimate carbon emissions and other ecosystem services implications. We developed and tested a system for national-wide data validation, which was prototyped in Central Africa:.
The same approach was implemented for the entire tropical biome to estimate aboveground carbon loss in natural and managed forests from to Our current activities include adaptation of our global data processing system for national monitoring agencies, as was done for Peru:. A comprehensive system of tree cover mapping and monitoring was developed and prototyped for Bangladesh.
The system is based on the national Landsat-based forest extent and change mapping and area estimation using stratified samples. PCI Geomatica Tutorials. PCI Geomatica is one of the leading commercial image processing tools. PCI offers a day trial version of the fully functional Geomatica software web-site registration required. Statistical Sampling. Primary materials concerning the GLAD sampling approach:. Olofsson et al.
This is a good introductory paper, but it's practical use is limited due to the issues listed above. Stehman et al. Works for any strata. Works for sample interpretation with proportions of target classes for each sample e. Tyukavina et al. GFOI Integration of remote-sensing and ground-based observations for estimation of emissions and removals of greenhouse gases in forests. This is a comprehensive set of guidelines on calculating uncertainties. Cochran W. Sampling Techniques. A comprehensive textbook on sampling methods.

A geographic information system GIS is a computer-based tool for mapping and analyzing feature events on earth. GIS technology integrates common database operations, such as query and statistical analysis, with maps. GIS manages location-based information and provides tools for display and analysis of various statistics, including population characteristics, economic development opportunities, and vegetation types.

Also, this book assesses the impacts of climate change on natural resources using both RS and GIS, as well as other applications, covering different parts of Iraq. The book chapters include tens of maps extracted from the remotely sensed datasets, in addition to tables and statistical relations obtained from the results of the studies of the chapters' authors. These studies have been conducted in different parts of Iraq; in the north Kurdistan region with its mountainous and undulating lands, in western parts which have desert soils, and in central and southern Iraq where there are salty soils, dunes, wetlands, and marshes.
The economic, social and cultural viability of any nation is mainly determined by the land and water resources that it has Harahsheh, These natural resources are essential to the economy of a nation since they play a critical role in the provision of employment, they are a source of raw materials for various industries, acts as a source of food and income, medicine as well as energy. The aesthetic beauty that relates to natural resources is always regarded as the cultural representation of nations. For instance, when one talks about the grand canyon, the picture of the United States comes into mind. When one talks about oil wells, one thinks about the Middle East.
Remote Sensing data is one of the primary data sources in GIS analysis. The objective of this material is to provide fundamentals of Remote Sensing technology.

The book is therefore a useful source of information and knowledge on Iraqi environment for graduate students, researchers, policy planners, and stakeholders in Iraq as well as similar regions.

The lockdown in the wake of COVID has disrupted all economic activities including agriculture throughout the globe. Though the annual growth of Indian agriculture has been 3. To strengthen agricultural economics research for providing economically viable, socially-acceptable and environmentally-feasible policy options for science-led agricultural growth.
Она попыталась высвободиться. Коммандер не отпускал. Она попробовала закричать, но голос ей не повиновался. Ей хотелось убежать, но сильные руки тянули ее .
Сьюзан затаила дыхание.
Я требую выпустить меня отсюда. В ответ - тишина. Его руки крепче сжали ее шею.
Не видно, чтобы он пользовался электронной картой у главного входа. Поэтому он определенно. Бринкерхофф с облегчением вздохнул: - Ну, если он здесь, то нет проблем, верно. Мидж задумалась. - Может .
Но Беккер не слушал, что тот. Он рассчитал все .
Как же так? - Сьюзан откинулась на спинку стула. - У нас внизу работают лучшие программисты в мире. И мы нашими совместными усилиями даже близко не подошли к математической функции меняющегося открытого текста. А вы хотите сказать, что какой-то панк с персональным компьютером придумал, как это сделать. Стратмор заговорил тише, явно желая ее успокоить: - Я бы не назвал этого парня панком.
Что случилось. По голосу Стратмора, мягкому и спокойному, никто никогда не догадался бы, что мир, в котором он жил, рушится у него на глазах.
