Question 19

Consider a geospatial dataset that was created through a multi-stage process. Initially, raw satellite imagery was orthorectified using a Digital Elevation Model (DEM). Subsequently, this orthorectified imagery underwent atmospheric correction using a specialized algorithm. The orthorectification process utilized a DEM sourced from the National Geospatial Agency, while the atmospheric correction algorithm was developed internally by the data-producing organization. How should the lineage information for this dataset be structured according to ISO 19115-1:2014 to accurately reflect these distinct origins and processing steps?

Accepted Answer

Include two separate `processStep` elements within the `lineage` element. The first `processStep` should describe the orthorectification, referencing the DEM as its `source`. The second `processStep` should describe the atmospheric correction, referencing the internal algorithm as its `source`.

Question 20

Consider a scenario where a geospatial analyst, Anya, is compiling a new land cover dataset for a mountainous region. This new dataset is derived from two distinct sources: a high-resolution satellite imagery mosaic and a pre-existing digital elevation model (DEM). The satellite imagery was subjected to a radiometric calibration and atmospheric correction process, while the DEM was resampled to match the spatial resolution of the imagery. Finally, both processed datasets were used as inputs for a supervised classification algorithm to generate the final land cover product. Which ISO 19115-1:2014 metadata element is most appropriate for explicitly detailing the original, distinct sources that were utilized in the creation of Anya\'s final land cover dataset, within the context of the overall lineage information?

Which metadata element, as defined by the standard, is primarily responsible for encapsulating the sequence of operations and the source data that led to the current state of this dataset, and what is the inherent scope of this information?

Accepted Answer

The lineage information, with its scope inherently pertaining to the dataset's provenance and transformations.

Question 25

Consider a geospatial data processing workflow where a vector dataset, originally in a geographic coordinate system, undergoes a reprojection to a projected coordinate system. This reprojection operation specifically modifies the geometry of features belonging to a single, defined feature type (e.g., \"RoadSegment\") within that dataset. When documenting this transformation using ISO 19115-1:2014 metadata, which value for the `level` element within the `scope` of the relevant `processStep` would most accurately reflect the direct impact of this reprojection operation?
