Overview
After selecting your Area of Interest (AOI) in the first of the DORA Prediction Map workflow, you can configure the grid resolution by adjusting the pixel count. Pixel presets refer to how the AOI is divided for processing and analysis. The pixel size will affect the resolution and detail of the learning data and your generated target clusters and VRIFY Prospectivity Score (VPS).
AOI Parameters
The AOI will always be a rectangular or square shape with DORA. You can choose from different pixel dimension configurations when configuring it:
Higher resolution provides more detail but increases processing time. For early-stage experiments, start with moderate resolution to speed up iterations.
Resolution | Example Size | Best For | Trade-offs |
Low | 256px x 256px | Broad, sparse, lower-quality AOIs | Fastest processing, least detail |
Medium | 512px x 512px (default) | Balanced AOIs | Good balance of speed and detail |
High | 1024px x 1024px | Small, well-mapped AOIs | Most detail, slower processing |
For horizontal (east-west) rectangles, prioritize higher resolution on the width to capture more detail across that direction. For vertical (north-south) rectangles, focus on adding more resolution to the height to improve the detail of that orientation.
Note: Keep in mind that you want to keep the pixels of your grid as square as possible.
Example:
Note: The size of the AOI determines the resolution scale, but the pixel count itself does not change.
Example:
AOI dimensions: 10 km (height) x 4 km (width)
Grid size: 1024 x 512 pixels
Resulting pixel dimensions:
Height per pixel = 10,000 m ÷ 1024 = ~9.8 m
Width per pixel = 4,000 m ÷ 512 = ~7.8 m
Once you have selected your pixels, you can zoom in to view the individual pixels to see how they impact the resolution of your AOI.
Adding a New AOI
If you want to create a new AOI shape, such as setting an AOI in a different area, you will need to upload a new file.
To do so, draw the new AOI in a shapefile (.shp) using your preferred GIS or modelling software and drag and drop the six files associated with this new AOI to the viewing window in DORA when in the AOI menu. Your newly-created AOI will then be available to select.
