1 . A method, comprising:

receiving input data regarding an agricultural block,

wherein the input data includes a row span of the agricultural block, a tree span of the agricultural block, a block heading of the agricultural block, at least one image of the agricultural block, and at least one location sample obtained at a location in a row within the agricultural block;

performing image recognition on the at least one image of the agricultural block to identify lines within the at least one image of the agricultural block;

identifying at least one polygon within the agricultural block based on the lines within the at least one image of the agricultural block; and

identifying map rows within each of the at least one polygon.

2 . The method of claim 1 , wherein the step of performing image recognition on the at least one image of the agricultural block to identify lines within the at least one image of the agricultural block comprises sub-steps of:

performing thresholding on the at least one image;

converting the at least one image to at least one grayscale image based on the thresholding;

performing additional thresholding on the at least one grayscale image;

converting the at least one grayscale image to at least one binary image based on the additional thresholding;

smoothing the at least one binary image to generate at least one smoothed binary image;

detecting at least one line within the at least one smoothed binary image;

analyzing a vector of a parametric line equation of each of the at least one line;

sorting the at least one line by Y-intercept; and

filtering the at least one line by proximity.

3 . The method of claim 2 , wherein a threshold for the step of performing thresholding on the at least one image is calculated using Otsu's method.

4 . The method of claim 2 , wherein the step of converting the at least one image to at least one grayscale image is performed using an averaging process, a desaturation process, or a decomposition process.

5 . The method of claim 2 , wherein the step of performing additional thresholding on the at least one grayscale image is performed using clustering-based thresholding or Otsu's method.

6 . The method of claim 2 , wherein the step of smoothing the at least one binary image to generate at least one smoothed binary image is performed using Gaussian blurring.

7 . The method of claim 2 , wherein the step of detecting at least one line within the at least one smoothed binary image is performed using (a) a voting scheme, (b) a morphologic method including steps of dilation, erosion, and dilation, or (c) a Hough transform algorithm.

8 . The method of claim 2 , wherein the step of filtering the at least one line by proximity is performed based on at least the row span.

9 . The method of claim 1 , wherein the step of identifying at least one polygon within the agricultural block based on the lines within the at least one image of the agricultural block is performed by a process that includes tracing a path around each of the at least one polygon.

10 . The method of claim 1 , wherein the step of identifying map rows within each of the at least one polygon is performed based on at least based on the row heading of the agricultural block, the row spacing of the agricultural block, and the at least one location sample obtained at the location in the row within the agricultural block.

11 . The method of claim 1 , further comprising the step of generating a tree-level map of the agricultural block.

12 . The method of claim 11 , wherein the step of generating the tree-level map of the agricultural block is performed by generating a tree-level map for each of the at least one polygon within the agricultural block.

13 . The method of claim 12 , wherein the step of generating a tree-level map for each of the at least one polygon within the agricultural block includes:

generating a plurality of lines of trees within each of the at least one polygon;

generating a first tree location of each one of the plurality of lines at an intersection of the each one of the plurality of lines and a boundary of the polygon in which the each one of the plurality of lines is located; and

generating subsequent tree locations along the each one of the plurality of lines based on the first tree location and the tree span.

14 . The method of claim 13 , wherein the plurality of lines of trees is generated based on assuming that a line of trees exists between each pair of adjacent rows within each of the at least one polygon.

15 . The method of claim 14 , wherein the plurality of lines of trees is further generated based on assuming that a line of trees exists between each boundary of the at least one polygon and a one of the rows that is adjacent to each boundary of the at least one polygon.
