This dashboard documents the evaluation evaluation and availability of the administrative boundary (COD-AB) layers and live services and population statistics (COD-PS) tables on HDX.  The dashboard has four tabs:


Usability Evaluation Overview


Detailed Evaluation


ITOS Live Web Services


Frequently Asked Questions



COD-ABs and COD-PSs should be evaluated according to established criteria to maintain standardized levels of quality.


CODs may be evaluated:

  • Informally by country IM teams at any time
  • Semi-formally by the country IM every year for the re-endorsement process
  • Formally by OCHA FIS when CODs are loaded or re-loaded to HDX.  These evaluations are reflected in the COD Dashboard (discussed below).


Evaluation criteria

CODs should be prepared for administrative level 0 (country), administrative level 1, and for additional administrative levels that are available and relevant.

CODs should be evaluated according to the established standard criteria (below) for comparability.  FIS uses a numeric scoring algorithm [to be documented later] that computes usability levels for each administrative level and overall.   (All administrative level 0 data, and the last evaluation Ecriteria groups ‘Link to COD-PS’ and ‘Link to COD-AB’ do not influence the usability evaluation.)

  • Fully usable:  The COD can be used for any purpose
  • Partly usable:  The COD has some problems that may limit its use
  • Needs improvement:  The COD is only useful for very limited purposes

COD AB Criteria

Metadata
Attribute structure
  • Is the COD-AB available on HDX?
  • Is the data public on HDX?
  • Is the date of the dataset indicated on HDX?
  • Is there a short but complete description of the dataset?
  • Is the data source clearly indicated and defined on HDX?
  • Is there any methodology or comments containing clarified information?
  • Is the file tagged as being a COD?
  • Is the COD-AB endorsed by IMWG?
  • Is the type of license/rights of use defined on the HDX website?
  • Are all the COD-AB files grouped as one unique entry on HDX?
  • Is there only one file per format per level? (e.g., only one SHP for each level)
  • Is the COD-AB attribute table also available as an Excel file on HDX?
  • Is the .CPG file present within the zip (when needed : AB names in arabic, russian, french, spanish)?
  • Is there a metadata file (txt) present with the COD-AB?
  • Is the zip naming convention followed?
  • Is the count of polygons different between sources (GDAM, Wikipedia) ? If yes put the number with the source in brackets and some eventual explanation in the comments
  • Are there names in all records?
  • Do the column names respect the naming convention?
  • Are all the names transcripted into latin script when required if other script is local language? (e.g., Latin script name included with Arabic name)
  • Is there a specific Excel file containing all the AB level units? (Excel - Gazetteer)
  • Do the lower admin boundaries have the higher admin boundaries in the shp ?
  • Are there any duplicate names within the level?



P-codes
Parentage
  • Are there names in all records?
  • Do the P-codes incorporate values from higher levels?
  • Are there any duplicate P-codes within the level?
  • Does each admin level have upper level P-codes? Is the hierarchy the same between levels?
  • Does each admin level have upper level names? Is the hierarchy the same between levels?
