The three main challenges in the field data collection for GIS are: -developing spatial reasoning skills -adopting changes in technology -acceptance
Some potential drawbacks of GIS maps include the risk of data inaccuracies, challenges with data integration from different sources, and the possibility of misinterpretation due to the complexity of the information presented. Additionally, there may be issues related to data privacy and security when using GIS maps for sensitive information.
Some common challenges with GIS include data accuracy and quality issues, interoperability between different systems, data privacy and security concerns, and the complexity of GIS software for non-experts. Additionally, the costs associated with maintaining and updating GIS technology can be prohibitive for some organizations.

GIS is Geographic Information Systems. Simply put,it is software used for mapping. It can ingest myriad types of data, satellite data being just one kind. GIS software like ArcMap does not NEED satellite data. So I suppose your answer is from zero to an infinite number.
Geomatics is a field that combines traditional surveying techniques with spatial data analysis using geographic information systems (GIS). It involves the collection, storage, processing, and presentation of geographic data to support decision-making in various industries such as urban planning, natural resource management, and environmental assessment.
The 3 primary GIS data types that GPS receivers collect are: spatial data (latitude and longitude coordinates), attribute data (information about the location like elevation or time), and metadata (details about the data collection process such as accuracy or date).

Recent technological advances like remote sensing, Geographic Information Systems (GIS), and mobile mapping technology have greatly assisted geographers in studying the Earth. Remote sensing allows for data collection from satellites and drones, while GIS enables geographers to analyze and visualize spatial data efficiently. Mobile mapping technology provides real-time data collection in the field, enhancing the accuracy and detail of geographical studies.

A GIS is a computer system capable of capturing, storing, analyzing, and displaying geographically referenced information; that is, data identified according to location. Practitioners also define a GIS as including the procedures, operating personnel, and spatial data that go into the system.GIS based application is a five staged process or we can say GIS have 5 components that involves the following:Data AcquisitionPre ProcessingPost ProcessingData ManagementData RenderingIf you wan't more information about these GIS steps visit the related links for detailed information about GIS and its component. This is the link of a company named Albireo Telematics which is a leader in GIS services, so I think they will answer your question the best way.
Remote sensing provides valuable data for GIS by allowing for the collection of information from a distance using sensors on satellites or aircraft. This data can be used to create detailed maps, monitor changes in the environment, assess land cover and land use, and analyze spatial patterns. Remote sensing helps to enhance the accuracy, efficiency, and scope of GIS applications.

Geomatics is a field that combines traditional surveying techniques with spatial data analysis using geographic information systems (GIS). It involves the collection, storage, processing, and presentation of geographic data to support decision-making in various industries such as urban planning, natural resource management, and environmental assessment.
Spatial data in GIS refers to any data that is associated with a location or geographic area. This can include maps, satellite imagery, GPS coordinates, and other forms of geospatial information. Spatial data is a fundamental component of GIS as it allows for the visualization, analysis, and interpretation of geographical relationships.
Some disadvantages of GIS include the high cost of software and data, the need for specialized training to use GIS effectively, and potential issues with data accuracy and reliability. Additionally, GIS can sometimes be limited by hardware constraints and may require regular updates to maintain functionality.
