Binational Soils Map for Ambos Nogales Watershed Erosion Modeling

A 235 km² digital map of soil parameters for the Ambos Nogales watershed, spanning southern Arizona and northern Sonora, Mexico, was prepared for soil erosion modeling. The dataset merges historical analog soil maps from Arizona with larger-scale digital soils data from Sonora to address cross-border data discrepancies. The summary was provided by the USGS.

Use Cases

• Estimate soil erosion risk using modeled soil parameters as input for erosion models.
• Analyze cross-border soil data discrepancies by comparing merged map features from different classification systems.
• Model watershed hydrology by using the digital soil map to inform soil property inputs for the Nogales Wash tributary area.
• Harmonize international geospatial data by studying the methodology of merging analog and digital soil maps for a binational region.

Strengths

• Covers a defined area of 235 square kilometers.
• Integrates data from two countries to create a unified map for a specific watershed.

Limitations

• Specific row/column counts, sample size, and data resolution are unknown.
• The dataset's creation date and temporal coverage are not specified, limiting time-series analysis.
