  • Polygon decomposition - spatial and GIS analysis

    Most vector GIS packages support some decomposition procedures, through overlay of a template or cookie cutterpolygons (e.g. the Clip operation in ArcGIS) and/or through the provision of explicit decomposition procedures. For example, complex polygons with convoluted boundaries may be divided up into a series of non-overlapping convex polygons.

  • Gas-Insulated Substations - GIS

    SF6 decomposes in the high temperature of an electric arc, but the decomposed gas recombines back into SF6 so well that it is not necessary to replenish the SF6 in GIS. There are some reactive decomposition byproducts formed because of the trace presence of moisture, air, and other contaminants. The quantities formed are very small.

  • What Is Decomposition?

    This is called decomposition. Bacteria, fungi, and some worms are what break down dead plants, animals, and insects. The bacteria, fungi, and worms are called decomposers. Decomposers need to eat some of the dead things so they can live and grow. The tiny pieces left over after decomposers eat become part of the soil.

  • What is a geographic information system (GIS)?

    A Geographic Information System (GIS) is a computer system that analyzes and displays geographically referenced information. It uses data that is attached to a unique location.Most of the information we have about our world contains a location reference: Where are USGS streamgages located? Where was a rock sample collected? Exactly where are all of a citys fire hydrants?

  • The SF6 Decomposition Mechanism: Background and

    Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases.

  • Decomposition - Wikipedia

    Decomposition is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere.

  • Quadtree - Wikipedia

    A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are the two-dimensional analog of octrees and are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The data associated with a leaf cell varies by application, but the leaf cell represents a "unit of interesting spatial information".
