Table of Contents

The GeoPackage for each excavation area (EA) should contain at least the following items used for both daily day planning and archival purposes.

[EA]_context_illustration_polygons #

  • A multi-part polygon layer for archival illustration of spatial contexts, in which each record is used for only one material or area (e.g., ceramic, earthen, stone; burning, bioturbation) of one spatial context
  • Attribute table fields
    • Manual entry
      • context_key (text, 50)
      • context_number (numerical, short)

  • Load style settings from kap_ea_polygon_type_2023.qml
  • Check that label settings have been applied from loaded style:
    • To set label calculation, select Properties> Attribute Form> Label, set Defaults value to “context_type”||’ ‘||”context_number”, and check the checkbox for “Apply default value on update”
    • To ensure label placements are recorded in the attribute table, select Properties> Label> Placement, and set the data defined overrides for X, Y, and Rotation (if they are shaded yellow, they are on)
