A technique called GIS (Geographic Information System) gathers data to produce a unique digital map. The many layers of this map indicate the locations of all living things (trees, buildings, roads, and people) as well as non-living things (buildings, water supplies, and cars). Because of the increasing demand for organising and analysing geographic information, GIS technology first appeared in the 1960s. It can show us the relationships between various data points, such as land use, transportation networks, population density, and so on. For instance, it can assist us in determining the best ..read more

Electromagnetic radiation, once produced by the Sun, embarks on a complex and lengthy journey before it is detected and recorded by sensors. The initial phase involves the radiation traversing the vacuum of space, a void where it remains untouched and unaltered by matter. This portion of the journey is uninterrupted, as space is largely empty and lacks substances that could interact with the energy. Upon reaching the outer limit of Earth’s atmosphere, the radiation enters a new phase of travel, where it begins to encounter atmospheric gases and particles. This interaction can take a multitude ..read more

Electromagnetic Energy (EME) spans across an extensive spectrum of wavelengths that exhibit various properties and behaviors. At the shorter end of the spectrum lie highly energetic gamma rays and X-rays. Gamma rays, with the shortest wavelengths, typically originate from nuclear reactions and are used in fields such as astronomy, nuclear medicine, and sterilization due to their penetrative power. Just beyond gamma rays in the electromagnetic Energy are X-rays, familiar to most people for their application in medical imaging. Despite their similar nature, X-rays typically have longer wavelengt ..read more

Remote sensing is a sophisticated process used to analyze and gather data about an object or area from a distance, typically using satellite or airborne instruments. Here are the seven components of the remote sensing process: Energy Source or Illumination (A): The first component is the source of electromagnetic energy that illuminates or provides electromagnetic energy to the target of interest. In most cases, this is provided by the sun. Radiation and the Atmosphere (B): As the energy travels from its source to the target, it must traverse through the Earth’s atmosphere. This interaction c ..read more

Remote sensing is a highly interdisciplinary field that involves the science and art of acquiring information about an object, area, or phenomena indirectly, that is, without physically touching it. This process is accomplished by capturing data through various types of devices such as satellites, aircraft, or drones that carry sensor equipment designed to observe and measure different characteristics of the Earth’s surface or atmosphere. The measurement or acquisition of information of some property of an object or phenomenon, by a recording device that is not in physical or intimate contact ..read more

what is gis ? geographic information system (GIS) is a data creation, management, analysis, and mapping system for various kinds of information. GIS links information to a map by fusing location data which tells us where things are with various kinds of descriptive information which tells us what those things look like. This offers a basis for research and mapping that is utilised in nearly all fields of study and business. Users can better grasp linkages, patterns, and geographic context with the aid of GIS. Better management and decision-making, as well as increased efficiency and communicat ..read more

The basis for both forest planning and forest policy, forest inventory is a procedure for gathering data on the quality and quantity of forest resources. Modern forest inventory concepts support a holistic view of forest ecosystems, addressing not only timber production but also the multiple functions of forests as well as the need to understand the working mechanisms of forest ecosystems, in contrast to early concepts of sustainable forest management and forest inventory that were focused on timber production.

In this blog post, I will discuss how to analyze the spatial relationships in regression residuals, which are the differences between the observed and predicted values of a dependent variable. Analysis of Spatial relationships in residuals can indicate whether the regression model adequately captures the spatial variation of the data, or whether there are spatial patterns that are not explained by the model. There are different methods to assess the spatial relationships in residuals, such as visual inspection, spatial autocorrelation tests, and geographically weighted regression. I will brief ..read more
