## How to Use the Spatial Resolution Calculator

The Spatial Resolution Calculator enables users to calculate the spatial resolution of an imaging system or camera. By inputting specific parameters, such as sensor size, focal length, distance, resolution, and display size, users can obtain the spatial resolution value. This value represents the number of pixels per unit distance, providing valuable insights into the level of detail captured by the imaging system.

## Primary Applications of the Calculator

The Spatial Resolution Calculator finds its applications in the following areas:

• Photography: Photographers can use this calculator to assess the spatial resolution of their camera system. By considering factors like sensor size, focal length, and resolution, photographers can understand the level of detail captured by their equipment, aiding them in making informed decisions regarding image composition, cropping, and printing.
• Remote Sensing: In remote sensing applications, such as satellite or aerial imaging, spatial resolution plays a crucial role. Analysts and researchers can utilize this calculator to determine the spatial resolution of the imagery and assess its suitability for specific applications, such as land cover classification or object detection.
• Display Technology: For display systems, such as monitors or projectors, understanding the spatial resolution is important in achieving optimal image quality. By inputting the display size and resolution into the calculator, users can evaluate the pixel density and assess the level of detail and sharpness that can be achieved on the screen.

## Instructions for Utilizing the Calculator

To effectively use the Spatial Resolution Calculator, follow these steps:

• Sensor Size: Input the size of the camera sensor or imaging device in millimeters (mm). The sensor size affects the field of view and the number of pixels captured.
• Focal Length: Enter the focal length of the lens or imaging system in millimeters (mm). The focal length determines the magnification and field of view.
• Distance: Provide the distance between the imaging system and the subject of interest in meters (m). This parameter affects the scale and level of detail captured.
• Resolution: Input the resolution of the imaging system in pixels. This value represents the number of pixels used to capture the image.
• Display Size: Enter the size of the display or viewing medium in inches. This parameter is relevant when assessing the quality and level of detail visible on the screen.

After filling in all the required fields, click on the Calculate Spatial Resolution button to obtain the spatial resolution value.

The resulting table will display the following information:

• Sensor Size: The input value of the sensor size.
• Focal Length: The input value of the focal length.
• Distance: The input value of the distance.
• Resolution: The input value of the resolution.
• Display Size: The input value of the display size.
• Spatial Resolution: The calculated spatial resolution, representing the number of pixels per millimeter (pixels/mm).

## Spatial Resolution Calculator Formula

The spatial resolution is calculated using the formula:

Spatial Resolution = (Sensor Size * Resolution) / (Focal Length * Distance)

This formula determines the number of pixels captured per unit distance based on the provided parameters.

## Illustrative Example

Let's consider an example to illustrate the functionality of the Spatial Resolution Calculator.

Suppose we have the following input values:

• Sensor Size: 22.2 mm
• Focal Length: 50 mm
• Distance: 5 meters
• Resolution: 24 megapixels (24 million pixels)
• Display Size: 10 inches

After inputting these values into the calculator, we find that the spatial resolution is approximately 26.67 pixels/mm.
