The Application C7 ratio H / D - hypsometric relation - operates with the diameter and height data obtained and recorded in the application of survey data I, and proceeds to fit regression models with calculations of regression coefficients and others like coefficient of determination (R2), standard error of estimate (Sxy). There are 12 pre-defined templates that are commonly used in such surveys.
       From the selection of a fitted model and the data entry of DAP, the program calculates the estimated heights of trees located in the area where sampling was established hypsometric relation.
      The result of the fitted model is recorded in a table SQLite Database (Floresta_7.db3), located on the SD card in the device campeiro / db, which can be read and interpreted by the Forestry System in CR Campeiro7 or by other managers BD compatible
