What key step follows the acquisition of field data in GIS?

The key step that follows the acquisition of field data in GIS is georeferencing. This process involves assigning a spatial reference to the collected data, which is crucial for its integration into the existing geographic information system. Georeferencing ensures that the field data aligns correctly with other spatial data layers and is positioned accurately in relation to real-world geographic coordinates.

By accurately placing the acquired data on a map, users can analyze and visualize it in conjunction with other datasets. This step is critical to maintaining the integrity and usability of GIS data. Without proper georeferencing, the subsequent analysis, visualization, or decision-making could lead to errors or misinterpretations of the spatial relationships.

While data visualization and data storage are also important aspects of managing GIS data, they typically occur after the georeferencing step. Project completion is an end goal but does not represent a step in the workflow following data acquisition. Georeferencing distinctly establishes the foundation for further data processing and analysis.
