Overview
This section of VRIFY AI is where you set the AOI (Area of Interest) for your experiment. This allows you to filter your input features and learning points to only find the ones that are covered in the designated area of interest. Features outside of the specified AOI won’t be included in this experiment’s feature set.
Read on for more context and explanations about what this step entails.
For steps on configuring Select AOI, see here.
Key Concepts by Parameter
Parameter: AOI
Setting an AOI (Area of Interest) is crucial, because it focuses the model on the specific geographic region targeted within your experiment, resulting in more precise analysis and relevant insights.
The format for your AOI will always be a square/rectangular shapefile (.shp)
If you do not see the expected shapefile(s) available in the drop-down menu, Reach out to your dedicated VRIFY AI Contact or email Support@VRIFY.com.
Parameter: Resolution (px)
The Height and Width parameters set the resolution for your AOI.
As these settings are adjusted, the view panel will reflect the shape and density of your AOI grid.
The number of pixels impacts the resolution of the results. The higher the pixels, the higher the resolution.
Note: a high resolution is not always ideal. Keep in mind the resolution of the input features (input data) when increasing the resolution of the AOI settings.
For smaller, well-defined AOIs, a high resolution may yield better results.
For more broad, less defined AOIs, a lower resolution may be more ideal.
Tip: Selecting a high resolution will increase computing time. For your initial experiments, you may want to choose a somewhat lower resolution in order to proceed through the steps faster, then increase resolution on your final runs.
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.

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.
