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.

2. A method as defined in claim 1, further comprising:

sorting 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; and

determining 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.

3. A method as defined in claim 2, further comprising selecting the first one of the geographical zones to sample based on whether a number of geographical zones that have been selected from a same one of the bins as the first one of the geographical zones satisfies a threshold.

4. A method as defined in claim 1, wherein the geographical feature comprises at least one of a total linear length of roads within the first one of the geographical zones, a number of buildings within the first one of the geographical zones, a number of motor vehicles within the first one of the geographical zones, water presence and area within the first one of the geographical zones, a total parks and recreation land area within the first one of the geographical zones, a ratio of residential to commercial areas usage within the first one of the geographical zones, an industrial land area within the first one of the geographical zones, green area within the first one of the geographical zones, or parking lot area within the first one of the geographical zones.

5. A method as defined in claim 1, wherein the observable landmark comprises at least one of an intersection of multiple streets or a street address.

6. A method as defined in claim 1, further comprising:

sub-dividing a second one of the geographical zones into multiple sub-divided geographical zones;

measuring the geographical feature represented in the image for corresponding ones of the sub-divided geographical zones;

storing descriptions for the sub-divided geographical zones in the computer memory; and

storing values representative of the geographical feature for the sub-divided geographical zones.

7. A method as defined in claim 1, wherein the geographical feature is representative of a population or a market within the first one of the geographical zones.

8. A method as defined in claim 1, further comprising:

retrieving the image of the geographic area of interest from an image repository in response to receiving a request for an identification of one or more sampling areas for the geographic area of interest; and

selecting the first one of the geographical zones based on the geographical feature to be included in a set of geographical zones to be sampled in a survey, the selecting the first one of the geographical zones to cause the survey to more closely represent the geographic area of interest compared to a different selection 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; 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.

10. An apparatus as defined in claim 9, further comprising 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.

11. An apparatus as defined in claim 10, wherein the sample stratifier is to select the first one of the geographical zones to sample based on whether a number of geographical zones that have been selected from a same one of the bins as the first one of the geographical zones satisfies a threshold.

12. An apparatus as defined in claim 9, further comprising an image retriever to obtain the image of the geographic area of interest from an image repository.

13. An apparatus as defined in claim 9, wherein the image divider is to sub-divide a second one of the geographical zones into multiple sub-divided geographical zones, the apparatus further comprising a zone analyzer to measure the geographical feature represented in the image for corresponding ones of the sub-divided geographical zones, and the memory is to store descriptions for the sub-divided geographical zones with values representative of the geographical feature for the sub-divided geographical zones.

14. An apparatus as defined in claim 9, wherein the geographical feature is representative of a potential market within the first one of the geographical zones.

15. An apparatus as defined in claim 9, further comprising:

an image retriever to retrieving the image of the geographic area of interest from an image repository in response to a request for an identification of one or more sampling areas for the geographic area of interest; and

a sample stratifier to select the first one of the geographical zones based on the geographical feature to be included in a set of geographical zones to be sampled in a survey, the sample stratifier to select the first one of the geographical zones to cause the survey to more closely represent the geographic area of interest compared to a different selection of the geographical zones.
