## Abstract

Methods and systems are disclosed including dividing a sensitive geographic region into three or more work regions; selecting geo-referenced aerial images for each particular work region such that at least a portion of the particular work region is depicted; transmitting, without information indicative of the geographic location depicted, a first of the images for a first of the work regions to an operator user device; receiving, from the device, at least one image coordinate selected within the first image by the operator, wherein the image coordinate is a relative coordinate based on a unique pixel location within the image raster content of the first image; and transmitting, without information indicative of the geographic location depicted, a second of the images for a second of the work regions to the operator user device, wherein the first and second work regions are not geographically contiguous.

## Claims

### Claim 1

A method, comprising the steps of:
dividing, by a processor of a server computer, a sensitive geographic region of interest of a requester into three or more work regions;
selecting, by the processor of the server computer, a first geo-referenced aerial image for a first work region of the three or more work regions such that at least a portion of the first work region is depicted in the first geo-referenced aerial image;
selecting, by the processor of the server computer, a second geo-referenced aerial image for a second work region of the three or more work regions such that at least a portion of the second work region is depicted in the second geo-referenced aerial image;
transmitting, by the processor of the server computer, image raster content of the first geo-referenced aerial image of the first work region to an operator user device without a location represented by the first geo-referenced aerial image being selected by a data processing operator of the operator user device and without information indicative of geographic location of a geographic area depicted in the first geo-referenced aerial image, wherein the data processing operator is different from the requester;
receiving, by the processor of the server computer from the operator user device, at least one first image coordinate representing an object or region of interest selected within the first geo-referenced aerial image by the data processing operator of the operator user device, wherein the first image coordinate is a relative coordinate based on a unique pixel location within the image raster content of the first geo-referenced aerial image, the pixel location having pixel row and pixel column coordinates; and
transmitting, by the processor of the server computer, image raster content of the second geo-referenced aerial image for the second work region to the operator user device without the location represented by the second geo-referenced aerial image being selected by the data processing operator of the operator user device and without information indicative of geographic location of a geographic area depicted in the second geo-referenced aerial image, wherein the second work region is not geographically contiguous with the first work region.

### Claim 2 (depends on 1)

The method of claim 1, further comprising the step of:
determining, by the processor of the server computer, which work regions have had image raster content of the geo-referenced aerial images previously transmitted to the data processing operator.

### Claim 3 (depends on 1)

The method of claim 1, further comprising the step of:
translating, by the processor of the server computer, the first image coordinate into real-world geographic coordinates representing the object or region of interest selected within the first geo-referenced aerial image by the data processing operator of the operator user device, using geo-referencing information of the first geo-referenced aerial image.

### Claim 4 (depends on 3)

The method of claim 3, further comprising the step of:
storing, on a non-transitory computer readable medium, the real-world geographic coordinates representing the object or region of interest selected within the first geo-referenced aerial image by the data processing operator of the operator user device.

### Claim 5 (depends on 3)

The method of claim 3, wherein data indicative of attributes of the data processing operator is stored with the real-world geographic coordinates.

### Claim 6 (depends on 3)

The method of claim 3, wherein at least two image coordinates are received and translated into real-world coordinates, and further comprising the steps of:
calculating, by the processor of the server computer, a measurement based on the real-world geographic coordinates; and
storing the measurement on a non-transitory computer readable medium.

### Claim 7 (depends on 6)

The method of claim 6, wherein the measurement is at least one of distance, height, slope in elevation, area, and surface area of a vertical or pitched surface.

### Claim 8

A system, comprising:
a secure server computer having a processor; and
one or more geo-referenced aerial image accessible by the processor of the server computer, the geo-referenced aerial images containing image raster content depicting an area, geo-referencing information, and real-world geographic coordinates of the geo-referenced aerial image; and
wherein the processor of the server computer executes computer executable instructions to cause the processor to:
divide a sensitive geographic region of interest of a requester into three or more work regions;
select a first geo-referenced aerial image for a first work region of the three or more work regions such that at least a portion of the first work region is depicted in the first geo-referenced aerial image;
select a second geo-referenced aerial image for a second work region of the three or more work regions such that at least a portion of the second work region is depicted in the second geo-referenced aerial image;
transmit image raster content of the first geo-referenced aerial image of the first work region to an operator user device without a location represented by the first geo-referenced aerial image being selected by a data processing operator of the operator user device, wherein the data processing operator is different from the requester, without information indicative of geographic location of a geographic area depicted in the first geo-referenced aerial image;
receive, from the operator user device, at least one first image coordinate representing an object or region of interest selected within the first geo-referenced aerial image by the data processing operator of the operator user device, wherein the first image coordinate is a relative coordinate based on a unique pixel location within the image raster content of the first geo-referenced aerial image, the pixel location having pixel row and pixel column coordinates; and
transmit image raster content of the second geo-referenced aerial image for the second work region to the operator user device without the location represented by the second geo-referenced aerial image being selected by the data processing operator of the operator user device, without information indicative of geographic location of a geographic area depicted in the second geo-referenced aerial image, wherein the second work region is not geographically contiguous with the first work region.

### Claim 9 (depends on 8)
