   Jul 22, 2024 · This image file size calculator will help you estimate the file size of an uncompressed raster image file, provided that you know the image's resolution and its bit depth. In this calculator, you'll learn what an image file is, what bit depth means, and the difference between a raster image and a vector image.

   The file size of a raster used to be easy to calculate. You would compute the grid size (the product of the number of columns and rows) and multiply this by the size of the raster data type. So, the file size was related to the grid size. This rule does not apply for an MRR and computing the file size of an MRR is far more complicated for the ...

   In a GIS, the spatial resolution of an image dataset is important, especially when displaying or comparing raster data with other data types, such as vector. In this case, resolution refers to the pixel size — the area covered on the ground and represented by a single pixel. A higher spatial resolution implies that there are more pixels per ...

   Image datasets have a unique way of defining geographic location. Once the pixels are accurately georeferenced, an ordered list of the pixel values in an image or raster is available. This means that each raster dataset typically has a header record containing its geographic properties, and the body of the content is an ordered list of pixel ...

   How do you determine a raster image file size?

   • Two parameters define a raster image's file size, and these are the number of pixels in the image and the bit depth of each pixel. To determine the file size of a raster image file, we have to multiply these variables together.

   How many bits are in a raster image?

   • Each pixel in a raster image typically takes up about 1 to 8 bits for black-and-white images and 8 to 64 bits for colored images. And the more pixels an image has, the more data it stores and the larger its file size. We can determine the number of bits per pixel with what we call "bit depth."

   How to check the cell size in a raster dataset?

   • To check the cell size in a raster dataset, first check the metadata associated with the raster data. If there is no metadata, you can find the cell size in the data source tab (under properties).

   Why do raster images have a smaller pixel size?

   • More objects on the ground, smaller objects, or greater detail in the extents of ground features can be represented by an image with a smaller pixel size. However, smaller pixel sizes result in larger raster datasets to represent an entire area. This requires greater storage space, which often results in longer processing time.

   What is a raster image?

   • Images are spatial data models that define space as an array of equally sized pixels, arranged in rows and columns, and composed of single or multiple bands. Each pixel contains an attribute value and location coordinates. Images are often referred to as rasters.

   What is raster grid size?

   • The grid size is the number of cells in a raster, usually expressed as the product of the number of columns and rows. In an MRR we can extend this concept, as MRR does not have a simple rectangular structure. The file size of a raster used to be easy to calculate.

   As a practical example, if you have a classification raster, where each raster cell corresponds to a class, you don't need to save your raster as a float32 (which many applications have a default), but the data type int serves you very well also. the resulting raster will be if you combing it with a compression algorithm of a few megabytes ...
