"dct:description": "Allocated oil and gas block licence data as geodata based on MEITI 6th data summary Report (1st April to 30th September 2018) published annex data and block coordinate list released by MEITI in 2020 (https://myanmareiti.org/sites/myanmareiti.org/files/publication_docs/license_information1st_april_to_30_september2018.xlsx & https://myanmareiti.org/en/publication/6th-meiti-summary-data-report).\nThe dataset contains all oil and gas blocks that were allocated during fiscal year period 1st April to 30th September 2018 and attributes such as type of block, type of activity, operating companies, etc.\nAs the MEITI licence annex data contains some inaccuracies and errors, P. Oswald used coordinate information contained in a separate document shared by MEITI in 2018 (https://myanmareiti.org/files/uploads/4._updated_combined_onshore_offshore_psc_blocks_conditions_all.pdf) as well as a best-guess approach to correct those.\nThis dataset includes the original and cleaned data columns.\nAdditional processing attributes were added during the data generation by P. Oswald. The detailed description of attribute fields can be found in attached metadata attributes excel sheet.
Lineage:
Version 2022-07-15: updated Metadata and attribute names
Version 2021-07-01:\nAttribute data downloaded from MEITI https://myanmareiti.org/sites/myanmareiti.org/files/publication_docs/license_information1st_april_to_30_september2018.xlsx on 2021-05-01.\nComparison of all fields with MEITI 5th Report. As no differences were detected, the dataset for MEITI 5th report for Oil and Gas was copied and used.\nMethodology for the MEITI 5th Oil and Gas Licence data below: \nData columns cleaned & standardized by P. Oswald (correct obvious typos, remove unnecessary spaces, standardize value domains where possible, etc.).
Geometry created based on coordinate information columns by conversion of coordinate values to GIS data and connecting the coordinates with straight lines (in ArcMap using SRS EPSG4326) to oil and gas block polygons.\nLinking the MEITI 5th report attribute data to the block geometries.\nIn absence of coordinates defining the eastern extend of the block PSC-R, this data uses the non-authoritative township boundary geometry curated by CDE Myanmar (unreleased version 2020-10-20) to fill this data gap in the MEITI data.
Other obvious data quality issues were improved by using coordinates from a separate oil and gas licence block coordinates document shared by MEITI in 2018 (https://myanmareiti.org/files/uploads/4._updated_combined_onshore_offshore_psc_blocks_conditions_all.pdf) as well as by applying a best guess approach with some issues remaining unresolved or undetected.

The detailed description of attribute fields can be found in attached metadata attributes excel sheet.\nThe generation of the geodata is based on the coordinate values (usually "6 digit One Inch" coordinates) for every licence block. \nAs the mineral mining license information shared by Department of Mining with MEITI was not based on the better quality Mineral Mining Pre-Cadastre but on another lower quality excel list, P. Oswald estimates that at least 30% of all mineral mining licenses have some sort of quality issues. Out of 1246 mineral mining licences reported in the MEITI annex, 28 could not be processed, over 300 licences had at least one wrong or missing coordinate, and approx. 40 licences had only one simplified centre coordinate instead of mining block boundary coordinates.Lineage:

As P. Oswald (as well as MEITI) has no access to the underlying individual licence contracts nor other verified reference data, the completeness and correctness of the data and cross-checking or reliable corrections cannot be undertaken.
Preliminary assessments indicate that many coordinates in the licence information annex are simplified, inaccurate, wrong or completely missing.\nThus, the generated licence geodata data inherits those data quality problems. In some cases P. Oswald corrected obviously wrong coordinates using a "best-guess" approach.\nThose corrections include correcting obvious typos and data input errors in excel, the “squaring” of concession blocks if one coordinate is very far away from all the other licence block coordinates, changing the order of the coordinates to avoid self-overlapping block boundaries, creating a circular shape of the size of the permitted area around the centre point when only one coordinate was provided, change of One Inch Map sheet numbers to make the coordinates fit with the indicated township location description etc.\nEdits performed are documented in processing-attributes added to the data sets.

Version 2021-07-01:
Data downloaded from MEITI https://myanmareiti.org/sites/myanmareiti.org/files/publication_docs/license_information1st_april_to_30_september2018.xlsx on 2021-05-01.
Data columns cleaned and standardized by P. Oswald (obvious typos corrected, removal of whitespaces and line breaks, standardize value domains where possible, etc.).
Matching of descriptive location information with island names from topographic maps where possible.
Geometry created based on coordinate information columns by conversion of coordinate values to GIS data and connecting the coordinates with straight lines (in ArcMap using SRS EPSG4326) to pearl cultivation licence area polygons.
Linking the MEITI 6th report attribute data to the licence block geometries.
As P. Oswald (as well as MEITI) has no access to the underlying individual licence contracts nor other verified reference data, the completeness and correctness of the data and cross-checking or reliable corrections cannot be undertaken. Preliminary assessments indicate that many coordinates in the licence information annex are simplified, inaccurate, wrong or completely missing.
Thus, the generated licence geodata data inherits those data quality problems. In some cases P. Oswald corrected obviously wrong coordinates using a “best-guess” approach.
