Methods, apparatus, and articles of manufacture to measure geographical features using an image of a geographical location
First Claim
1. A method, comprising:
- dividing, by executing an instruction with a processor, an image of a geographic area of interest into geographical zones, the geographical zones being representative of different physical geographical areas;
storing, by executing an instruction with the processor, descriptions for the geographical zones in a computer memory based on modified boundaries of a first one of the geographical zones;
sorting, by executing an instruction with the processor, the geographical zones into bins based on a comparison of values representative of the geographical zones to ranges of values, the ranges of values corresponding to the bins;
determining, by executing an instruction with the processor, a number of zones to be sampled in one of the bins based on the range of values corresponding to the one of the bins;
storing, by executing an instruction with the processor, a value representative of a geographical feature represented in the image for the first one of the geographical zones;
generating, by executing an instruction with the processor, a sampling plan having a sampling area based on the value; and
manually sampling the sampling area based on the sampling plan.

Abstract
Methods, apparatus, and articles of manufacture to measure geographical features using an image of a geographical location are disclosed. An example method includes dividing an image of a geographic area of interest into geographical zones, the geographical zones being representative of different physical geographical areas; modifying boundaries of a first one of the geographical zones to more closely conform to an observable landmark or a geographical location observable by a person located in the first one of the geographical zones; storing descriptions for the geographical zones in a computer memory based on the modified boundaries of the first one of the geographical zones; and storing a value representative of a geographical feature represented in the image for the first one of the geographical zones.

9. An apparatus, comprising:
-
an image divider to divide an image of a geographic area of interest into geographical zones and to modify boundaries of a first one of the geographical zones to more closely conform to an observable landmark or a geographical location observable by a person located in the first one of the geographical zones; a sample stratifier to sort the first one of the geographical zones into one of a plurality of bins based on a comparison of a value corresponding to the first one of the geographical zones to ranges of values, and to determine a number of samples for the first one of the geographical zones based on the one of the bins, the ranges of values corresponding to the bins, the image divider and the sample stratifier being implemented with a processor; and a memory to store a description of the first one of the geographical zones based on the modified boundaries of the first one of the geographical zones with a value representative of a geographical feature of the first one of the geographical zones based on a feature in the image, the sample stratifier to generate a sampling plan having a sampling area based on the value to facilitate manually sampling the sampling area based on the sampling plan. - View Dependent Claims (11, 12, 13, 14, 15)

10. A tangible computer readable medium comprising machine readable instructions which, when executed, cause a machine to at least:
-
divide an image of a geographic area of interest into geographical zones, the geographical zones being representative of different physical geographical areas; store descriptions for the geographical zones in a computer memory based on modified boundaries of a first one of the geographical zones; sort the geographical zones into bins based on a comparison of values representative of the geographical zones to ranges of values, the ranges of values corresponding to the bins; determine a number of zones to be sampled in one of the bins based on the range of values corresponding to the one of the bins; store a value representative of a geographical feature represented in the image for the first one of the geographical zones; and generate a sampling plan having a sampling area based on the value to facilitate manually sampling the sampling areas based on the sampling plan. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
