invalid Y-coordinate for location KOMo

veenstrajelmer commented 7 months ago

incorrect location

import matplotlib.pyplot as plt
plt.close("all")
import ddlpy

locations = ddlpy.locations()
bool_stations = locations['Y'] < 3e6
selected = locations.loc[bool_stations]
print(selected[["Naam","X","Y","Coordinatenstelsel"]].sort_index())

# Create a spatial plot
fig, ax = plt.subplots(figsize=(13, 8))
ax.plot(locations.X, locations.Y, 'k.')

Gives:

This issue has been passed on to our data delivery partner, and will be fixed by the next metadata synchronisation in a few weeks time. The coordinate should be equal to KOMb; X 654848.317 Y 5880513.971

Update 16-5-2024 (and 9-10-2024): @TvLoon-RWS There is now one additional station with incorrect y-coordinates. Output from the python code in the initial issue description:

The incorrect coordinates are in DDL but not in DONAR.

TvLoon-RWS commented 1 month ago

HKN has for a brief moment been given data under these faulty coordinates. This has been since 2024-06-12. new data is now given out under HKN with coordinates X 587398.972 Y 5839436.37

A new synchronization with the list of live locations is planned next month. Hopefully KOMo is corrected by that point.
