Overview
After selecting your Area of Interest (AOI), 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 VPS scores. Keep in mind:
Higher pixel count offers more detail but increases processing time.
Lower pixel count processes faster but provides less detail.
AOI Parameters
The AOI will always be rectangular or square shape with VRIFY AI, and you can choose from different pixel dimension configurations when configuring it:
256px x 256px: Fastest processing, suitable for preliminary or larger scans with less detail.
512px x 512px: Balanced processing speed and detail.
1024px x 1024px: Highest detail with the slowest processing, ideal for detailed, focused analysis.
For horizontal (east-west) rectangles, prioritize higher resolution on the width to capture more detail across that direction. Meanwhile, for vertical (north-south) rectangles, focus on adding more resolution to the height to improve the detail of that orientation.
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 6 files associated with this new AOI to the viewing window in VRIFY AI when in the AOI menu. Your newly created AOI will then be available to make predictions. Alternatively, you can reach out to your VRIFY AI contact for assistance.
