FieldGenius for Windows Basics | Importing and Localization
This deployment guide details the process required to import external vector CAD drawings and execute a multi-point GNSS local coordinate transformation inside MicroSurvey FieldGenius for Windows. Following these procedures aligns global satellite positions safely with existing localized site control infrastructure grids.
CAD Drawing Import
Before pulling vector linework graphics into your active layout screen canvas, you must establish an identical database frame:
- Initialize your FieldGenius field project database directory.
- Confirm that all core settings match your specific survey criteria requirements, including distances, operational angles, linear units, and regional coordinate systems.
- Access the master dashboard overlay, open the main menu panel layout, and select Import/Export.
- Choose CAD/LandXML/Templates and click directly on DGN/DXF/DWG Import.
- Locate your targeted vector engineering line blueprint file inside the built-in system file explorer window and tap open to render it across your workspace.
Control Point Acquisition
To tie local drawing layouts accurately to actual physical spaces, operators must establish geometric control pairs by capturing true ground locations:
- Identify several prominent, physical control marker monuments across your site that explicitly correspond to designated intersecting lines or text points within your imported CAD drawing.
- Locate the first physical point monument out on the ground, position your GNSS rover rod assembly precisely over the marker center, wait for a stable RTK fixed solution, and shoot the control coordinates.
Repeat this procedure for all remaining site control markers. Your final calculated spatial transformation parameters become exponentially more accurate as you increase the overall volume of control points used, as well as the linear physical distance between them across the project boundaries.
GNSS Local Transformation
Once your field observations are securely captured, execute the transformation routine to mathematically morph your coordinate frameworks together:
- Open the main menu workspace dashboard and select Survey Tools.
- Choose GNSS Local Transformation from the advanced calculations module list.
- Tap Modify Parameters and select the Similarity method option to process uniform horizontal shifts, system rotations, and scaling adjustments.
- Return back to the primary GNSS Local Transformation management view and choose Modify Control.
- Tap an entry from your Local Control database list, then map it directly to its corresponding recorded GNSS Control observation point pair.
Minimum Pairing Requirements: Field operators must establish and successfully bind at least two independent point pairs to execute a valid Similarity spatial local transformation matrix.
Transformation Verification
Upon saving and closing your completed transformation calculation variables, FieldGenius updates the active mapping engine. Your live global satellite positioning tracks smoothly and registers flawlessly on top of your imported engineering drawing and active map files. Your localization sequence is finished, your site grid offsets are matched, and your configuration setup is ready for production staking layouts.
