Extracting data from PMTiles viewer #554
-
|
This question may have already been asked, but I’d really appreciate any help. I’ve loaded a PMTiles file from my local drive to PMTiles Viewer and can successfully view each data point on the map along with its attributes. How can I export all of those data points and their associated attributes to a CSV or Excel file?" |

PMTiles is not an appropriate format for that use case, because there is duplication of features when they cross tile boundaries or in lower zoom levels, and loss of features at lower zoom levels. If you need the ability to export to CSV, you should use a row-based tabular format like GeoJSON, FlatGeobuf or GeoParquet. |

Thank you Brandon.
My challenge is , I downloaded the pmtiles file from the web site. Is it
possible the Geojson or other type of data should be residing there as well
or they are completely invisible?
Please let me know when got a chance.
Thanks again for your help.

That is up to whoever published the dataset, you may want to ask them instead. |
