GeoExpress Python Package

• GeoExpress: Python Package for compression of Satellite, Aerial and Drone Imgery

• The GeoExpress Python Package provides a thin, Pythonic wrapper around the GeoExpress engine, enabling programmatic access to MrSID raster compression, decompression, metadata management, and security operations. It is designed for automation, batch pipelines, and integration into larger GIS, remote sensing, and GeoAI workflows.

• MrSID raster compression & decompression\
• JPEG2000 (JP2 / GMLJP2) encoding\
• NITF / NITFJP2 workflows\
• LiDAR (LAZ ↔ SID) conversion\
• Metadata management\
• Password protection (locking/unlocking)\
• Batch automation

Supported Conversions

TIFF → MG2 / MG3 / MG4 (MrSID)

from geoexpress import encode_safe

encode_safe("c:/data/input.tif", "c:/data/output.sid", format="MG4", options={"cr": 20})
encode_safe("c:/data/input.tif", "c:/data/output.sid", password="1234")  # Auto MG3

TIFF → JP2 / GMLJP2

encode_safe("c:/data/input.tif", "c:/data/output.jp2", options={"cr": 10})
encode_safe("c:/data/input.tif", "c:/data/output.jp2", format="JP2")

TIFF → NITF / NITFJP2

encode_safe("c:/data/input.tif", "c:/data/output.ntf")
encode_safe("c:/data/input.tif", "c:/data/output.ntf", format="NITFJP2")

---

SID Decoding (Recommended Method)

SID conversions, use decode() for

SID → TIFF

from geoexpress import decode_safe

decode_safe(
    input=r"C:\data\input.sid",
    output=r"C:\data\output.tif"
)

SID → JP2

decode_safe(
    input=r"C:\data\input.sid",
    output=r"C:\data\output.jp2"
)

SID → NITF

decode_safe(
    input=r"C:\data\input.sid",
    output=r"C:\data\output.ntf"
)

---

JP2 → SID / TIFF

from geoexpress import encode_safe

encode_safe("c:/data/input.jp2", "c:/data/output.sid", format="MG4")
encode_safe("c:/data/input.jp2", "c:/data/output.tif")

NITF → TIFF

encode_safe("c:/data/input.ntf", "c:/data/output.tif")

---

LiDAR Support

LAZ ↔ SID

from geoexpress import encode_safe

encode_safe("c:/data/input.laz", "c:/data/output.sid")

---

Image Information

from geoexpress import info_parsed

info = info_parsed("c:/data/image.sid")
print(info["parsed"])

---

Metadata

Set Metadata

from geoexpress import set_metadata_safe

set_metadata_safe("c:/data/image.sid", "Author", "GeoExpress Package")

Get Metadata

from geoexpress import get_metadata_safe

print(get_metadata_safe("c:/data/image.sid"))

---

Lock / Unlock

Lock

from geoexpress import lock_image_safe

lock_image_safe("c:/data/input.sid", "c:/data/locked.sid", "1234")

Unlock

from geoexpress import unlock_image_safe

unlock_image_safe("c:/data/locked.sid", "c:/data/unlocked.sid", "1234")

---

Batch Encoding

from geoexpress.batch import batch_encode_safe

jobs = [
    {
        "input": "c:/data/input_a.tif",
        "output": "c:/data/output_a.sid",
        "options": {"cr": 20}
    },
    {
        "input": "c:/data/input_b.tif",
        "output": "c:/data/output_b.sid",
        "options": {"lossless": True}
    }
]

results = batch_encode_safe(jobs)
print(results)

---

CLI

geoexpress encode input.tif output.sid --of mg4 --cr 20
geoexpress info output.sid
geoexpress meta set output.sid Author=GeoExpress

---

Troubleshooting
