The Transformation Tool is a powerful feature designed to manipulate, adjust, and refine spatial data for various applications. This tool allows users to manipulate spatial data dimensions, adjust geospatial attributes, and ensure data is correctly positioned in its correct location. Placing the spatial data in the correct geolocation is as important as processing the data itself, ensuring accurate representation and usability in mapping and analysis. This guide outlines its key features and how you can use them effectively.
Opening the Transformation Tool
Navigate to the Settings section under the Layer you want to transform.
Select the appropriate Transform Tool based on your adjustment needs.
Important: Georeferenced spatial data may occasionally be offset from its expected position. Use Skand’s Transform Tools to manually adjust the coordinates and/or elevation as needed.
Applying a Transformation
3D Controls
Open the Transformation toolbar and select 3D Controls.
The interface will display different axes categorized into two types: 3D axes and rotation axes
3D axes: Consist of the X, Y, and Z axes, colored red, blue, and green, respectively. These are primarily used for linear adjustments to spatial data, corresponding to latitude/northing, longitude/easting, and elevation.
Rotational axes: Control rotations relative to the spatial data’s horizontal and vertical axes colored blue and green respectively
Latitude, Longitude, and Elevation Text Boxes
Use this tool only if you know the coordinates of the centroid of the bounding box of your spatial data. Manually enter the values in the provided text boxes.
Reset/Clear Position
You can reset the position of your data to its original state if you are not satisfied with the adjustments made (movement/rotation).
Best Practices
Use 3D controls to accurately align your data to its correct position.
Make sure to turn on 2D Aerial Map under View Mode to accurately guide you align your data.
See to it that you’ve applied the correct Spatial Reference System (SRS) to your model if your data is georeferenced.
Troubleshooting
Issue: Transformation Not Applying
Check if the dataset is properly loaded.
Ensure that the selected parameters are valid.
Try reloading the page and reapplying the transformation.
