What is a common issue faced by GIS services regarding image transmission?

Transmitting large images is indeed a common issue faced by GIS services. Large imagery can lead to several challenges, including increased bandwidth requirements, longer loading times, and potential delays in processing and analysis. High-resolution satellite or aerial images tend to be considerably large in file size due to the detailed information they capture.

This necessitates significant storage capacity and robust network infrastructure to facilitate efficient transmission, especially when dealing with high volumes of data or multiple users accessing the imagery simultaneously. The large size of images can also affect the performance of applications and services relying on these datasets, leading to a need for advanced techniques such as image compression, optimized data formats, or tiling methods to manage the delivery and presentation of this data more effectively.

In contrast, low memory usage, exclusivity to vector data, or consistently fast performance are not typical issues pertinent to image transmission in GIS services. These aspects do not align with the challenges posed specifically by large image files.
