Discuss the methods of GIS data inputs with suitable examples.

Global Navigation Satellite System (GNSS) and Geographic Information System (GIS) are two interconnected technologies that play a crucial role in mapping, navigation, and spatial analysis. While GNSS provides accurate positioning information, GIS utilizes this data for a variety of applications, ranging from urban planning to environmental management. In the context of GIS, data input is a fundamental step, involving various methods to capture, collect, and integrate spatial information. Let's explore some of the key methods of GIS data inputs along with relevant examples.

1. Global Positioning System (GPS):
   - Method: GPS is a satellite-based GNSS that enables precise positioning on the Earth's surface. GPS receivers capture signals from multiple satellites to determine the user's location in terms of latitude, longitude, and elevation.
   - Example: Field surveyors use handheld GPS __________ _____ ______ ____ _______.
