What is the process of converting one data model into another in GIS?

The process of converting one data model into another in GIS is referred to as data transformation. This involves altering data from one format or structure to another, ensuring that it aligns with the conventions and rules of the target data model.

Data transformation can include a variety of operations such as reformatting, aggregating, and applying different coordinate systems, which are crucial when integrating datasets from different sources or preparing them for specific types of analysis. This process is especially important in GIS because different applications and systems may use unique data models that require conversion to achieve compatibility.

In contrast, data migration typically refers to the process of moving data from one system or storage location to another, which may not necessarily involve changing the structure or model of the data itself. Data integration focuses more on combining data from multiple sources to present a unified view, while data cleansing involves correcting or removing inaccurate records from a dataset. Thus, these terms are related to data handling but do not specifically address the conversion of data models like data transformation does.
