The hook
Surveyors increasingly produce data for GIS — and consume GIS as a starting point. Knowing the data models, datum requirements, and accuracy expectations of the GIS world keeps the surveyor a trusted source rather than just another vendor.

Concepts that show up on the exam
Spatial database
A database with geometry as a first-class data type. PostGIS, Esri Geodatabase, BigQuery GIS. Foundation for modern enterprise GIS.
Metadata
Data about the data: datum, projection, accuracy, source, capture date, custodian. Without metadata, geo-data is useless.
Datum / projection compliance
GIS layers must be in the right CRS. Mixing without transformation creates registration errors.
Quality flags
Each feature should carry a quality category (surveyed, digitized from aerial, GIS-derived). Helps consumers know what they can trust.
Survey data → GIS conversion
Often involves field-to-finish coding, attribute mapping, schema alignment. The surveyor often delivers in a GIS-friendly format (shapefile, geodatabase).
