Attendees:

38.1 Key Discussion Points

38.1.1 1. Survey 1-2-3 Data Export Process

38.1.1.1 Current Status

  • Nora has completed entry of 15 pedons into Survey123
  • Team working on process to export data to Excel format for QC before NASIS upload
  • Identified some technical challenges:
    • Coordinates displaying incorrectly (some lat/long values reversed)
    • Points currently showing at 0,0 coordinates in web interface
    • Crashing issues when trying to input coordinates through map interface

38.1.1.2 Action Items

  • Nora to resubmit surveys with corrected lat/long coordinates
  • Export all 15 pedons to Excel format
  • Place exported files in shared Box folder
  • Team to test QC process using Excel format

38.1.2 2. Documentation and Communication Process

38.1.2.1 Team Decisions

  • Will maintain single running document in Box for questions/comments
  • All team members can edit document online simultaneously
  • Document will track:
    • Questions during data entry
    • QC feedback
    • Technical issues
    • Classification decisions

38.1.2.2 Process Updates

  • Patty will provide MLRA shapefile for reference
  • Team has access to site photos through Survey123 map interface
  • Will continue using Box for file sharing and collaboration

38.1.3 3. GIS and Mapping Progress

38.1.3.1 Current Work (Patty)

  • Analyzing geomorphic surfaces using multiple data sources:
    • USGS county data
    • Minnesota DNR land type associations
    • Howard Hobbs surficial geology maps
  • Waiting for current Minnesota Geological Survey layer
  • Working on identifying major land surfaces with different parent materials

38.1.3.2 Future Plans

  • Joe proposing machine learning approach to identify sampling locations
  • Will incorporate:
    • Geomorphic surfaces
    • Land use data
    • Various covariates
  • Plan to identify underutilized areas for future sampling

38.1.4 4. Land Use Classification Discussion

38.1.4.1 Current Considerations

  • Multiple potential classification schemes:
    • Met Council data
    • EPA impervious surface data
    • Land cover classifications
  • Ryder shared experience from previous urban soil survey:
    • Used EPA layer with 1-meter resolution
    • Combined land use and impervious surface data
    • Helped define urban land map units vs. residential areas

38.1.4.2 Next Steps

  • Adam to potentially lead land use classification effort
  • Team to investigate availability of EPA layer for Minnesota
  • Plan meeting with Joe to discuss classification approach

38.2 Action Items

38.2.1 For Nora

  1. Fix and resubmit surveys with reversed coordinates
  2. Export 15 pedons to Excel format
  3. Upload Excel files to Box
  4. Continue entering next batch of pedons
  5. Research spring semester meeting schedule options

38.2.2 For Patty

  1. Share MLRA shapefile in Box
  2. Continue geomorphic surface analysis
  3. Coordinate with Joe regarding machine learning approach
  4. Review exported pedon data when available

38.2.3 For Ryder

  1. Investigate EPA layer availability for Minnesota
  2. Share experience with urban soil classification
  3. Assist with QC process development

38.2.4 For Adam

  1. Begin investigating land use classification options
  2. Review Met Council data layers
  3. Prepare for discussion with Joe about classification approach

38.3 Upcoming Meetings

  • December 10, 2024: Meeting with Randy
    • Focus on data entry progress
    • Discuss QC process
    • Address any technical questions
  • December 13, 2024: Team social gathering
  • Spring semester meeting schedule to be determined after January 21st

38.4 Notes

  • No formal agenda required for December 10th meeting with Randy
  • Team should note questions for Randy ahead of time
  • Current meeting schedule runs through end of fall semester only
  • Spring schedule to be determined based on Nora’s class schedule

38.5 Technical Decisions

38.5.1 Data Entry Process

  • Continue using Survey 1-2-3 for initial data entry
  • Export to Excel for QC review
  • Final upload to NASIS after QC complete
  • Maintain running documentation of decisions and questions

38.5.2 Mapping Framework

  • Focus on geomorphic surfaces first
  • Incorporate land use classification later
  • Wait for Joe’s input on machine learning approach
  • Consider multiple classification schemes

38.5.3 Documentation

  • Use single running document in Box
  • All team members can edit simultaneously
  • Track questions and decisions in real-time
  • Maintain access to photographs through Survey 1-2-3

The next team meeting with Randy is scheduled for December 10, 2024. Team members should prepare questions and review initial batch of exported data before the meeting.
