  2. Tree height measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_height_measurement

    Tree Top Measurement. A pole is generally used to measure the remaining height of the tree. The climber pulls up an extendable pole and uses it to reach to the top of the tree from the point at the upper end of the tape. If not vertical, the slope of the leaning pole is measured and the length of the pole is measured.

  3. Tree measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_measurement

    There are direct measurements. Shorter trees can be measured using a long pole extended vertically to the top of the tree. Larger trees can be climbed and a tape measurement made from the highest point of the climb to the base of the tree. The distance to the top of the tree can be measured from that point, if needed, using a pole.

  4. Top tree - Wikipedia

    en.wikipedia.org/wiki/Top_Tree

    Top trees are used for maintaining a Dynamic forest (set of trees) under link and cut operations.. The basic idea is to maintain a balanced Binary tree of logarithmic height in the number of nodes in the original tree ( i.e. in (⁡) time) ; the top tree essentially represents the recursive subdivision of the original tree into clusters.

  5. Tree view - Wikipedia

    en.wikipedia.org/wiki/Tree_view

    A tree view is usually a vertical list of nodes arranged in a tree-like structure. [1] [2] Each node represents a single data item, displayed as an indented line of text or a rectangular box. The indentation (and sometimes a line drawn between nodes) is used to indicate levels of hierarchy. Every treeview has a root node from which all nodes ...

  6. Girard form class - Wikipedia

    en.wikipedia.org/wiki/Girard_form_class

    Girard form class is a form quotient calculated as the ratio of diameter inside bark at the top of the first 16 foot log to the diameter outside bark at breast height ().Its purpose is to estimate board-foot volume of whole trees from measurement of DBH, estimation of the number of logs, and estimation of the taper of the first log, based on the general relationships identified between the ...

  7. Tree allometry - Wikipedia

    en.wikipedia.org/wiki/Tree_allometry

    There are different tree species compositions in each region in the world and most of those regions have at least one equation that estimates tree volume from DBH. Research and the application of forest allometry have meshed over time to develop these quick equations to accurately estimate how much volume a particular forest stand holds.

  8. List of superlative trees - Wikipedia

    en.wikipedia.org/wiki/List_of_superlative_trees

    The original quoted figure of 100.8m was from the top leaves to the bottom of the buttresses on the low side of ground. The correct height of the tree is 97.58m – that is the average between the distance to the lowest part of bole and the distance to the highest part of bole [15] [16] Giant sequoia (Sequoiadendron giganteum) 95.7 314 United ...

  9. Tree (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Tree_(graph_theory)

    In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. [1] A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.
