synthetic data error generated coordinates cluster at centroid real geog

Not specified by the original author.

TL;DR

Fix this in synthetic data generator by acting on the exact message first: stop generating latitude and longitude as two independent numeric columns, instead sample a real locality or region first in proportion to production, then jitter coordinates inside that locality boundary, and plot or grid count the output against production to confirm the spread before release. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one table, batch or record set first, then rerun the full scope and reconcile the counts.

generated coordinates cluster at centroid - real geography lost

Use this when

• The operation in synthetic data generator fails with this exact message or symptom: generated coordinates cluster at centroid - real geography lost.
• The same failure repeats on retry with unchanged inputs.
• Generation, validation or export is blocked until this item completes.

Not for this skill when

• The message is an outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output quality. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in synthetic data generator, and copy the full message plus the table, column or job involved into the run notes. Verify: the error is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this error: stop generating latitude and longitude as two independent numeric columns, instead sample a real locality or region first in proportion to production, then jitter coordinates inside that locality boundary, and plot or grid count the output against production to confirm the spread before release. Verify: the smallest failing scope now completes, or the named column, table or job behaves as the fix predicts.
3. Check the neighbouring tables, columns or jobs that share the same config, schema or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in synthetic data generator on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts, distributions or status against the source in synthetic data generator so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Independent numeric modelling of coordinates centres both distributions on their means, so generated points pile up near the average location and the real multi centre geography disappears.

TL;DR

Fix this in synthetic data generator by acting on the exact message first: stop sampling sensor rows independently, add the time based features the seasonality lives in such as hour, day of week and month as explicit columns or context, use a sequential or time series synthesizer that conditions each step on the previous ones, and compare the periodogram or weekly averages of real and generated series before accepting the output. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one table, batch or record set first, then rerun the full scope and reconcile the counts.

Why it happens

Row independent generation destroys the time correlation that creates daily and weekly cycles, so the marginal distribution can match while the generated series stays flat over time.

TL;DR

Fix this in synthetic data generator by acting on the exact message first: restrict phone generation to the ranges reserved for fictional use in that country, for example the dedicated drama and test number blocks, replace the area or exchange part with a reserved code after generation, and screen the finished column against allocated range lists before release.

Why it happens

Realistic phone generators draw from the same numbering plan real subscribers use, so without a reserved range rule the output inevitably lands on numbers that belong to real people.
