Four burned area tools were implemented in Google Earth Engine (GEE), to obtain regular processes related (BA) mapping, using medium spatial resolution sensors (Landsat and Sentinel-2). The four are (i) the BA Cartography tool for supervised over user-selected extent period, (ii) two implementing a stratified random sampling select scenes dates validation, (iii) Reference Perimeter highly accur...

Mapping rice area is a critical resource planning task in many South Asia countries where the primary crop. Remote sensing-based methods typically rely on domain knowledge, such as crop calendar and phenology, supervised classification with ground truth samples. Applying Google Earth Engine (GEE) has been proven effective especially at large scale owing to comprehensive up-to-date data catalog ...

Semi-arid ecosystems play a key role in global agricultural production, seasonal carbon cycle dynamics, and longer-run climate change. Because semi-arid landscapes are heterogeneous and often sparsely vegetated, repeated and large-scale ecosystem assessments of these regions have to date been impossible. Here, we assess the potential of high-spatial resolution visible band imagery for semi-arid...

Urbanization often occurs in an unplanned and uneven manner, resulting in profound changes in patterns of land cover and land use. Understanding these changes is fundamental for devising environmentally responsible approaches to economic development in the rapidly urbanizing countries of the emerging world. One indicator of urbanization is built-up land cover that can be detected and quantified...

Cloud computing becomes more popular day by day. The “dream” of users to “to get rid” of administrators, huge investments on expensive hardware and human resources becomes true. The goal of this paper is to present a general overview of the new coming service offered by Google company Google App Engine. “What is it for?”, “What can I do with the system?” and “How does it work?” are some of the ...

In this paper, we present Active Cloud DB, an open source Softwareas-a-Service (SaaS) application that allows for RESTful access to cloud-based distributed datastore technologies that implement the Google Datastore API. We implement Active Cloud DB as a Google App Engine application that we employ to expose the Google App Engine Datastore API to developers – for use with any language and framew...

Google Earth provides an open source, easy to access and cost free image data that support map interest community. Therefore, depending of this community on Google Earth, grows up day by day. More than simply providing locational information, Google Earth allows users to add their own content such as photos or descriptions of areas or landmarks. They can also extrapolate information from the sa...
