Summary

The GT_ANNOGRID command in GeoTools is used to generate a map grid with annotations for a given map sheet, making it an essential tool for cartography, GIS applications, and survey mapping in BricsCAD, AutoCAD, ZWCAD and ARES Commander.

GeoTool -> Geological/Mining Tools -> General -> Create Map Grid

Key Features Include:

• Customizable Grid Creation:
  • Define the grid extents by selecting an existing sheet index block (created by GT_SHEETINS) or manually specifying the area.
  • Specify X/Y spacing for grid tick marks and grid annotation text.
• Flexible Annotation Options:
  • Choose between inside grid or outside grid annotation placement.
  • Customize coordinate labeling formats, including:
    • Easting/Northing (E/N)
    • X/Y Cartesian system
    • Meridian/Perpendicular (M/P)
• Predefined and Customizable Blocks:
  • Uses pre-defined blocks for grid tick marks and annotations (modifiable for custom styles).
  • Editable block templates include:
    • GRID_CROSS.dwg (grid tick marks)
    • TICK_LEFT.dwg, TICK_RIGHT.dwg, TICK_TOP.dwg, TICK_BOTTOM.dwg (annotation blocks).
• Scalable Grid Management:
  • Save and manage multiple annotation settings for different map scales.
  • Settings can be stored and restored from ASCII INI files for future use.
  • Set a preferred scale reference without affecting grid parameters.

Benefits:

This tool is ideal for surveyors, cartographers, and GIS professionals who need precise map grid annotation for mapping and documentation.
