BAGIS-PRO uses buffers when clipping individual layers with an ad hoc 'Clip Layers' tool and with the 'Batch PDF Export' tool. BAGIS-PRO currently lacks the capability to create an AOI and clip/buffer the DEM layer(s). BAGIS-V3 should be used for this purpose.
The Clip Layers allows the analyst to specify a buffer distance (in meters or kilometers) for each layer being clipped. When the tool loads, it queries each layer in the AOI to extract the current buffer distance from the metadata. This value will appear on the form as the buffer distance.
For layers that don't exist in the AOI, the suggested buffer distance will be set to the buffer distance from the buffered AOI layer (aoib_v). The distance of this buffer may vary depending on the buffer selected when the AOI was originally created.
If PRISM or SWE layers don't exist in the AOI, their buffer distances will be set to the PRISM buffer distance from the buffered AOI layer (p_aoi_v). This buffer distance may vary depending on the buffer selected when the AOI was originally created.
The Batch PDF Export tool utilizes the concept of managed and unmanaged layers when determining the appropriate default buffer distance.
Managed Layers:
Snotel and Snow Course sites layers: The default buffer distance for these layers is 5 kilometers. This distance can be overridden by editing the SnotelBufferDistance and SnotelBufferUnits values in the local batch_tool_settings.json file. Both the Snotel and Snow Course sites layers use these values.
PRISM layers, and the SWE layers: The default buffer distance for these layers is 1000 meters. This distance can be overridden by editing the PrecipBufferDistance and PrecipBufferUnits values in the local batch_tool_settings.json file. Both the PRISM and SWE layers use these value.
Unmanaged Layers: All other layers inherit the buffer distance from the buffered AOI layer (aoib_v). The distance of this buffer may vary depending on the buffer selected when the AOI was originally created.
