Discuss the methods of GIS data inputs with suitable examples.

Geographic Information Systems (GIS) are powerful tools used to capture, manage, analyze, and display spatial and geographic data. For GIS to function effectively, it requires the input of accurate and comprehensive data. The methods of data input into GIS can be broadly classified into three categories: direct input, indirect input, and derived input. Each of these methods has its specific techniques and applications that contribute to the construction of accurate geospatial databases.

### 1. Direct Input:
Direct input refers to methods where data is entered into GIS systems directly from various sources. These methods involve digitizing and capturing spatial information using different instruments.

a. Manual Digitizing:
Manual digitizing involves tracing features from hardcopy maps or aerial photographs onto a digitizing tablet or screen. _____ _____ _______ ______ ________ ____ ____ _______.
