Editing Balto/Graham Tools (section)

=== Section 1: Scenting Conditions ===

This section computes the estimated Probability of Detection (POD) based on the current conditions where the search will take place.

==== Location ====

Enter UTM coordinates for the search location in the format "12S 0379774E 3821798N", or tap the GPS button to use your current location. Balto validates the UTM format and shows red text if the format is invalid.

==== Date and Time ====

Enter the date and time for the search in YYYY-MM-DD hh:mm format, or tap the Now button to use the current time. This is used along with the location to compute the sun angle and shadow length.

==== Shadow Length ====

Balto automatically computes the expected shadow length in feet based on the location and time. This serves as a quick visual check — you can compare against an actual shadow you measure on a 6-foot stick to verify your inputs.

Check the Night box if the search is at night or in deep shade, which significantly affects scenting conditions.

==== Surface Type ====

Select the dominant ground cover from the dropdown. This adjusts wind speed based on the vegetation in the area.

==== Get Current Weather ====

Tap this button to fetch current weather conditions from the internet (when available) for the location coordinates. After the weather is fetched, a dialog displays temperature, humidity, wind speed and direction, and cloud cover at different altitudes. The wind speed and cloud cover dropdowns are automatically populated based on the weather data.

==== Wind Speed and Cloud Cover ====

These dropdowns are automatically set by Get Current Weather but can also be set manually. They feed into the POD calculation.

==== Estimated POD ====

Displays the estimated Probability of Detection at 100 meters based on the current conditions. This represents the percentage chance that a dog will detect a subject when working at 100m spacing.

==== Cumulative POD at Distances ====

A grid showing cumulative POD at decreasing grid spacings: 100m, 75m, 50m, 25m, and 12.5m. As grid spacing decreases (more thorough coverage), POD increases. Use this table to choose a grid spacing that meets your target detection probability.
