Which of the following is a key advantage of vector data?

The key advantage of vector data lies in its ability to represent geographic features in a dimensionally correct manner while maintaining smaller file sizes compared to raster data. Vector data formats use points, lines, and polygons to create precise and accurate representations of objects, such as roads, boundaries, and various geographical features. This accuracy is essential in many applications, such as urban planning, transportation, and environmental analysis.

Small file sizes are another significant benefit of vectors, as they store geometric data in a more efficient manner than raster data, which consists of grids or pixels. This efficiency allows for easier management and faster processing times within GIS software. Furthermore, vectors can provide high-resolution details without the loss of quality, making them ideal for applications requiring precise spatial analysis.

The other options highlight aspects that do not represent advantages of vector data. For example, dimensionality problems refer to challenges that may arise in representing data in more than two dimensions, while complex storage methodology suggests cumbersome management, which is not seen as an asset. Lastly, continuous phenomena, such as temperature or elevation, are typically better represented through raster data rather than vector formats, as rasters are structured to handle gradual changes across surfaces rather than defined boundaries.
