Releasing lonboard 0.14!¶
Lonboard is a Python library for fast, interactive geospatial data visualization in Jupyter.
This post gives an overview of what's new in Lonboard version 0.14.
Refer to the changelog for all updates.
PMTiles Raster support¶
As the first step towards broader raster data integration, we now support visualizing raster PMTiles archives through Lonboard.
For example, using an Obstore HTTPStore to read a PMTiles file over HTTP:
from async_pmtiles import PMTilesReader
from lonboard import Map, RasterLayer
from obstore.store import HTTPStore
store = HTTPStore("https://air.mtn.tw")
reader = await PMTilesReader.open("flowers.pmtiles", store=store)
layer = RasterLayer.from_pmtiles(reader)
m = Map(layer)
The RasterLayer supports only raster-formatted PMTiles archives; it doesn't support those containing vector data.
Category filtering in DataFilterExtension¶
The DataFilterExtension now supports categorical filtering, not just numeric range filtering.
See more details in the Jupyter Notebook Example.
This feature was contributed by @ATL2001.
Support for Pandas v3¶
Lonboard now fully supports Pandas v3.
