Overview
Each Data Augmentation Module produces a specific type of raster output. This article describes what goes in, what comes out, and how each module processes data — one row per module.
For background on Data Augmentation, see Data Augmentation: Overview. For how the workflow runs, see How Data Augmentation Works.
Outputs
Module | Simple Overview | Functional Summary | Technical Breakdown |
Distance Maps | Shows how close each cell is to things like roads, faults, or boundaries. | Rasterizes vector features (points, lines, polygons) into distance-to-feature rasters for spatial modelling. | Input: Vector data (.SHP) Output: Raster Key Parameters: Grid resolution, AOI, Vector category, Desired category Processing: Converts vector features into distance-to-feature raster. One grid raster per feature type if categories are specified. |
Data Density Maps
| Highlights areas where you have lots of information vs. little to none. | Creates a raster that reflects how many data layers are present per pixel, highlighting data-rich areas. | Input: Vector Data (.SHP), Raw Raster Output: Raster Key Parameters: Grid resolution, AOI Processing: Counts the number of layers informing each pixel to highlight data density. |
Structural Domain Maps | Creates a map of which way rock layers are tilted or folded underground. | Convert orientation measurements (strike/dip) into interpolated structural grids, vector fields. | Input: Measurement points (.SHP) Output: Raster Key Parameters: Grid resolution, AOI, Structure types, Strike, Dip, Right hand rule Processing: Converts structural measurements into interpolated strike field maps using transformation rules. |
Fault Disturbance Maps | Maps how the volume of rock is affected by a fault. | Model spatial influence and disturbance zones around fault lines with customizable decay. | Input: Line vectors (.SHP) Output: Raster Key Parameters: Grid resolution, AOI, Faults, Wavelength, Disturbance level, Decay Processing: Models wave-based disturbance zones around faults with decay scaling away from fault trace. |
Computer Vision Maps | Pulls out hidden patterns in the data using image recognition techniques. | Apply deep learning filters (feature extraction) to raster inputs to extract high-level spatial features. | Input: Raster Output: Raster Key Parameters: Grid resolution, AOI, Number of filters Processing: Applies deep learning, RESNET-50, to extract spatial features from raster data. |
Texture Filter Maps | Pulls out hidden patterns in the data using Haralick filters. | Apply deep learning filters (feature extraction) to raster inputs to extract high-level spatial features. | Input: Raster Output: Raster Key Parameters: Grid resolution, AOI, Number of filters Processing: Applies Haralick filters to extract spatial features from raster data. |
Multivariate Anomaly Maps | Flags areas where the data looks strange or unexpected when layers are compared together. | Detect anomalies based on multi-layer raster analysis using an anomaly scoring algorithm. | Input: Data Rasters Output: Raster Key Parameters: Grid resolution, AOI, Target grids Processing: Analyzes multiple grids to detect anomalies across all data, using a scoring algorithm across layers. |
Lineament Maps | Traces straight-line features like fractures or boundaries that show up in the data. | Identify and extract linear features (lineaments) using edge detection and line-following algorithms. | Input: Data Raster Output: Raster Key Parameters: Grid resolution, AOI, Edge detection sensitivity, Line length, Gaps, Orientation filters Processing: Detects and traces linear features from raster data using edge and line detection techniques. |
Gridded Maps | Links soil, till, or rock samples to auxiliary layers to predict values across the entire AOI, including areas without samples. | Uses predictive algorithms to find patterns between point-based data and auxiliary data; extrapolates those patterns across space using secondary datasets. | Input: Point-Based Data Output: Raster Key Parameters: AOI, data column(s), modality, smoothing kernel, selected auxiliary rasters, output resolution Processing: Trains a machine learning model on point samples and rasters to generate stable, averaged predictions. |
