Abstract: A system and method for determining an attribute of a plant may include obtaining, by a camera, an image of a region; producing, by a rangefinder, a measurement of a distance from the rangefinder to a plant in the region; and determining the height of the plant by correlating data in the image with the measurement.

Abstract: A method of storing and accessing data comprising receiving an initial data block, dividing the initial data block into a plurality of initial subblocks, each initial subblock being the same size, storing each subblock in accordance with a data schema, generating a set of calculated subblocks, each calculated subblock being generated from a plurality of initial subblocks, such that each calculated subblock is the same size as an initial subblocks, storing the calculated subblocks in accordance with the data schema, and generating a reference structure, the reference structure comprising a pointer to each of the stored subblocks.

Abstract: A method and apparatus for interpolating data on a data grid having a plurality of data grid points to provide an interpolated data value at an interpolated point offset from a data grid point by offsets x, y, the method comprising the steps of obtaining a data value and a plurality of derivative values for each of a set of data grid points defining a sub-grid, defining a 4×4 data value matrix from the data values and derivative values, defining a plurality of 4×4 transformation matrices, calculating a 4×4 coefficient matrix from the transformation matrices and the data value matrix, defining a x vector based on the offset x and a y vector based on the offset y, and calculating the interpolated data value from the x vector, y vector and coefficient matrix.
