### 2.1 Concepts and Characteristics of OSGEarth
OSGEarth is an open-source Geographic Information System (GIS) framework based on the OpenSceneGraph (OSG) engine, designed for creating three-dimensional geographic spatial information visualization applications. Its features include support for various geographic data formats, rich map rendering capabilities, dynamic data loading, and high performance.

### 2.2 Role and Functionality of GDAL
GDAL (Geospatial Data Abstraction Library) is an open-source library for reading, writing, and processing raster geospatial data. It supports format conversion, projection transformation, and dataset aggregation, among other features. GDAL is widely used in geographic information systems and is an important tool for processing geographic data.

### 2.3 Advantages of Integrating OSGEarth and GDAL
The integration of OSGEarth and GDAL facilitates the processing of different formats of geographic data within OSGEarth, leveraging GDAL's rich functionalities for data processing and conversion. Furthermore, it utilizes OSGEarth's rendering engine to display geographic information, thereby enhancing the effectiveness a
