[Unreleased]¶

Provenance in every export: the GeoTIFF records source (the service URL), interpolation, pixel_type, valid_range, created (UTC), software and valid_px as metadata tags. export(..., tags={...}) adds to them; Mosaic(..., tags=...) writes them when the mosaic is whole.
export(..., skip_empty=True): one coarse overview first, then no request for the tiles with no data on or next to them, filled with nodata. Off by default: a feature smaller than an overview pixel can be missed.
export(..., resume=True): checked tiles are kept in <dest>.tiles/ and reused by the next run after a failure; deleted once the file is whole.
Export.skipped and Export.reused.
aggregate(path, factor, valid_range=...): the mean and the valid share of each factor x factor cell, read one strip at a time.
Mosaic.fill(tile), occupied(), valid_mask(), read_band().
imageserver-mcp, an MCP server for AI agents (pip install "imageserver-export[mcp]"): list_layers, describe_layer, attribute_table, sample_point, area_summary, export_area. Every number is computed by the library; areas are capped in pixels; only export_area writes, into the output folder. stdio or streamable HTTP (/mcp, /health).

ImageServer.export(grid, dest): an area of any ArcGIS ImageServer as one tiled, compressed GeoTIFF, written to .part and renamed only when whole.
Grid.from_lonlat / Grid.snap: a target grid on whole pixels, reprojected with densified edges; plan() cuts it into tiles the server accepts.
export_params / check_image: one exportImage request, and the JSON error an ImageServer sends with HTTP 200.
ImageServer.info(), attribute_table(), list_services(), and eea(name) for the European Environment Agency's open Copernicus Land layers.
send=: route every request through your own HTTP layer.
