Check coordinates distance and bearing: Difference between revisions

Revision as of 18:01, 23 August 2016

There are three different cases of found issues with Distance and Bearing

migrated data that may not have FromPointGUID set
upgraded data from version 5 that will not have user_entered coordinates
a few cases where one point of a polygon where missing FromPointGUID and/or user_entered coordinates

NAA has found all three cases in Sri Lanka.

Case 2 First run this query to see if there is any coordinates that use Distance and bearing and do not have user_entered coordinates.

SELECT
geopoint.coordrefsys,
geopoint.coordformat,
geopoint.userinputformat,
Count(geopoint.geopoint_guid)
FROM
geopoint
WHERE
bearing IS NOT NULL AND
distance IS NOT NULL AND
user_entered_x IS NULL AND
user_entered_y IS NULL
GROUP BY
geopoint.coordrefsys,
geopoint.coordformat,
geopoint.userinputformat
ORDER BY
geopoint.coordrefsys ASC,
geopoint.coordformat ASC,
geopoint.userinputformat ASC

Case 2 If there are any with userinputformat Bearing and Distance then you MUST update them.

UPDATE geopoint
SET
user_entered_x = longitude,
user_entered_y = latitude

WHERE
bearing IS NOT NULL AND
distance IS NOT NULL AND
user_entered_x IS NULL AND
user_entered_y IS NULL
