Open Soil Profiles - testbed data portal for storing soil profile data Open Soil Profiles - testbed data portal for storing soil profile data Presentation Transcript

  • Open Soil ProlesTomislav HenglISRIC  World Soil Information, Wageningen University GSM2011.org, June 2024th 2011
  • GSIF components 1. Cyber infrastructure for input, analysis and visualization of data. 2. Global databases (legacy data, gridded covariates) that are main inputs to global soil mapping. 3. Software tools (modules and packages) and manuals for creation of geoinformation, for instance, according to the GlobalSoilMap.net specications. 4. Standards and protocols for data entry, map generation and data sharing. GSM2011.org, June 2024th 2011
  • Hypothesis Probably the most valuable legacy soil survey data are the eld records of soil properties i.e. soil prole observations GSM2011.org, June 2024th 2011 View slide
  • DenitionSoil eld record1: any georeferenced observation or measurement of soil properties (anything measured in soil medium) 1 Compare with e.g. http://www.geosamples.org GSM2011.org, June 2024th 2011 View slide
  • Book chapter GSM2011.org, June 2024th 2011
  • Proposed implementation 1. Build an open (real time Public access) data portal that can be used to collect and maintain world soil eld observations GSM2011.org, June 2024th 2011
  • Proposed implementation 1. Build an open (real time Public access) data portal that can be used to collect and maintain world soil eld observations 2. Use it to facilitate global soil mapping activities GSM2011.org, June 2024th 2011
  • Proposed implementation 1. Build an open (real time Public access) data portal that can be used to collect and maintain world soil eld observations 2. Use it to facilitate global soil mapping activities 3. Collect millions of points. . . GSM2011.org, June 2024th 2011
  • Basic principles 1. Soil surveyors / contributors remain owners of the data (read/write rights) GSM2011.org, June 2024th 2011
  • Basic principles 1. Soil surveyors / contributors remain owners of the data (read/write rights) 2. Anyone can contribute GSM2011.org, June 2024th 2011
  • Basic principles 1. Soil surveyors / contributors remain owners of the data (read/write rights) 2. Anyone can contribute 3. Anyone can use GSM2011.org, June 2024th 2011
  • Basic principles 1. Soil surveyors / contributors remain owners of the data (read/write rights) 2. Anyone can contribute 3. Anyone can use 4. (ISRIC will maintain and improve it) GSM2011.org, June 2024th 2011
  • GBIF GSM2011.org, June 2024th 2011
  • Global Surface Summary of the Day (GSOD) GSM2011.org, June 2024th 2011
  • There are probably millions of soil records out thereFigure: USDA NCSS Characterization Database, CSIRO National SoilArchive, ISRIC WISE, SPADE, Iran National soil prole database,Canadian Soil Information System, and African soil proles. GSM2011.org, June 2024th 2011
  • Lower Saxony Only in Lower Saxony (federal state in northern Germany) there are about 1.3 millions of soil proles and cores. 2 2 Rainer et al. (2011): Soil carbon balance in sensitive ecosystems in Europe. GSM2011.org, June 2024th 2011
  • Endangered speciesLegacy soil eld records are being lost as we speak. There is a considerable danger of being lost to eective use forever (!) GSM2011.org, June 2024th 2011
  • Types of soil observations (records) 1. Freeform Soil Records (FFSR) 2. Soil Prole Records in Original Form (SPROF) 3. Harmonized Soil Prole Records (HSPR) GSM2011.org, June 2024th 2011
  • FFSR Only a very limited number of basic site columns are absolutely required. Freeform soil records do not need to describe a whole soil prole (0200 cm) nor do they require any pedological or taxonomic data. Variable types (columns) are extendible. Entries are not restricted to standard measurement techniques. Metadata is attached to each new record and is a part of the record. GSM2011.org, June 2024th 2011
  • SPROF Soil Prole Records in Original Form (SPROF)are soil prole records that describe complete prole but are unharmonized(do not comply with a single international standard) GSM2011.org, June 2024th 2011
  • HSPR Are complete (core columns). Are ready for use (mapping and analysis). Contain soil variables required to produce maps according to GlobalSoilMap.net specications. Do not carry any metadata (metadata is standard). GSM2011.org, June 2024th 2011
  • Data entry scheme New entry Complete NO YES profile? Soil Profile Record NO in Original Form Harmonized YES (SPROF) values? Freeform soil Fill in the Harmonize Harmonized Soil record missing to referent Profile Record (FFSR) values method (HSPR) SOIL Open soil record REFERENCE Open soil profile LIBRARY OSRL0 OSPL0 Open Soil Profiles (ISRIC hosted enterprise DB) GSM2011.org, June 2024th 2011
  • Test-bed data portal GSM2011.org, June 2024th 2011
  • Data display / sharingFor convenience of automated use and for consistency, we proposethe following attributes for HSPD: One row = one record3 Column naming convention Uncertainty columns Access via URL or via ODBC (MySQL) 3 Although in the background we work with a relational DB. GSM2011.org, June 2024th 2011
  • 3D variablesA proposed standard naming convention. E.g. pH estimated in 1:5water solution for the initial soil depth layer becomes: variable type estimation model depth sequence P H I H O 5 _ A variable type estimation model T A X N U S D A GSM2011.org, June 2024th 2011
  • variable type estimation model depth sequenceSite observations P H I H O 5 . ASite information, such as soil classication by the USDA system canbe coded as: variable type estimation model T A X N U S D A GSM2011.org, June 2024th 2011
  • Summary points If meteorologists, ecologists have managed to build global data sets of eld records why cant we? GSM2011.org, June 2024th 2011
  • Summary points If meteorologists, ecologists have managed to build global data sets of eld records why cant we? If a government agency does not intend to sell their soil data, why not contribute to OSP (distributed hosting)? GSM2011.org, June 2024th 2011
  • Summary points If meteorologists, ecologists have managed to build global data sets of eld records why cant we? If a government agency does not intend to sell their soil data, why not contribute to OSP (distributed hosting)? Before we can use the OSP for soil mapping, we need to convert FFSR and SPROF to HSPR GSM2011.org, June 2024th 2011
  • Summary points If meteorologists, ecologists have managed to build global data sets of eld records why cant we? If a government agency does not intend to sell their soil data, why not contribute to OSP (distributed hosting)? Before we can use the OSP for soil mapping, we need to convert FFSR and SPROF to HSPR There is an enormous value in legacy soil eld data (forgotten goldmine) GSM2011.org, June 2024th 2011
  • Next steps Prepare entry templates for FFSR, SPROF and HSPR Focus on National soil prole datasets Invite people (IUSS, DSM, any soil surveyor) to contribute Popularize it GSM2011.org, June 2024th 2011
