Localization refers to the process of establishing and defining the coordinate system, geoid usage, scale factors, and alignment on a local coordinate system for accurately determining and recording the positions of points on the Earth's surface during surveying activities. This allows surveyors to effectively communicate and share data, as well as ensure consistency and accuracy in their measurements.
Localization consists of the following tabs:
Note: The process of localizing typically involves one or more of the following:
- Defining the coordinate system: Selecting a specific coordinate system to reference the surveyed points.
- Geoid usage: Determining the geoid model to use for calculating elevations and heights relative to mean sea level or other reference surfaces.
- Scale factors: Accounting for scale variations in measurements (e.g. Ground to Grid, Grid to Ground) due to factors such as map projections, ellipsoidal geometry, and terrain variations.
- Aligning on local coordinates: Establishing a local reference system tailored to the specific survey area, often based on user-defined coordinate systems or other predefined projections.
Note: As the localization information changes on a job, consider the use of the Raw Data - Process GPS routine to update the coordinates to reflect those changes.
Localization Report
Within each tab of the Localization interface is the Localization Report button (located to the left of ✅) that generates a report of the current localization. Upon clicking this button, the standard File Selector is launched that prompts for the name and location of the resulting report.
