leafmap Files

Patch release with ~60 bug fixes from a codebase-wide review and refreshed documentation.

Highlights

• Security: download_folder no longer disables TLS certificate verification. Arguments to gdown are now passed by keyword; they were passed by position, which put remaining_ok into gdown's verify slot.
• Float rasters are no longer truncated: array_to_image and array_to_memory_file keep float data as float for GeoTIFF/COG output. Previously, data such as NDVI in [-1, 1] was narrowed to integers and written as all zeros.
• Features that were broken now work:
• the toolbar split-basemap tool and split_map() with its default arguments
• OpenStreetMap functions with osmnx 2.x (osmnx 1.x still works)
• MapLibre add_vector_tile
• MapLibre layers added twice under the same name
• folium colormap_name and categorical colormaps such as NLCD
• deck.gl basemaps from xyzservices
• pandas 3, shapely 2 and Python 3.9 compatibility:
• datetime columns in any time unit
• string dtypes in classify and color_code_dataframe
• the removed applymap
• single Polygon and MultiLineString geometries in get_geometry_coords
• leafmap.cli and leafmap.download import again on Python 3.9
• Docs:
• rewritten Installation, Get Started and FAQ pages
• a new Command Line page for view-raster and view-vector
• API pages for the cli, mapbox and report modules

Behavior changes

• When dtype is not given, float arrays written to GeoTIFF/COG by array_to_image and array_to_memory_file stay float32/float64. The old range-based integer narrowing still applies to PNG/JPEG output and when a colormap is written.
• MapLibre add_date_filter_widget now defaults to startDatetime/endDatetime. These are the columns the widget always read, because it used to ignore its column parameters. A missing column now raises a clear ValueError.
• MapLibre add_layer returns the name the layer was added under. When that name was already taken, the layer is added as name_1, and its layer id is renamed to match.
• USE_MESSAGE_QUEUE is parsed as a boolean. Only 1, true, yes, y and on enable the queue; previously any non-empty value did, including False.
• clip_raster raises ValueError for geometry inputs without a CRS, unless they are GeoJSON dicts (assumed EPSG:4326) or geom_crs is given.
• download_with_progress raises on HTTP errors instead of saving the error page as data.
