MrSID Plug-in for ArcGIS 3D Analyst: Quick Installation GuideThis guide walks you through installing and configuring the MrSID plug-in (MrSID/GeoExpress codec) so ArcGIS 3D Analyst can read and display MrSID imagery reliably. It covers system requirements, download sources, step-by-step installation, configuration inside ArcGIS, common problems and fixes, and performance tips for working with large MrSID datasets.
What is MrSID and why it matters for ArcGIS 3D Analyst
MrSID (Multiresolution Seamless Image Database) is a wavelet-based image compression format developed by LizardTech (now Extensis). It delivers high compression ratios with efficient pyramid-style multiresolution access, making it well suited for large geospatial imagery such as orthophotos and aerial imagery. ArcGIS 3D Analyst benefits from MrSID because the format allows fast, on-demand access to different resolution levels—important when draping imagery over 3D terrain, creating oblique views, or working with large mosaics.
Key fact: MrSID supports high compression with multiresolution tiling for fast, scalable access in GIS applications.
System requirements and compatibility
Before installing, confirm compatibility:
- ArcGIS Desktop (ArcMap) or ArcGIS Pro version — check your ArcGIS version’s documentation for supported third-party raster formats.
- Operating system — Windows ⁄11 or corresponding server versions supported by your ArcGIS release.
- MrSID codec/plug-in — ensure you download a version compatible with your ArcGIS and OS (32-bit for legacy ArcMap 10.x when needed; 64-bit for ArcGIS Pro).
- Sufficient disk space and memory — working with large MrSID files benefits from ample RAM and fast storage (SSD recommended).
Key fact: Use the codec version matching your ArcGIS bitness (32-bit for ArcMap 10.x, 64-bit for ArcGIS Pro).
Where to get the MrSID plug-in / codec
Obtain the MrSID/GeoExpress codec from the official vendor (Extensis/LizardTech) website or from the Contributed Formats page of Esri if referenced. Look for downloads named “MrSID Codec” or “GeoExpress SDK/Viewer” that specify ArcGIS compatibility.
Pre-installation checklist
- Verify ArcGIS is closed before installing the codec.
- If upgrading, uninstall older MrSID codecs first (use Control Panel > Programs & Features).
- Note whether you need 32-bit or 64-bit installers. ArcMap requires 32-bit runtime; ArcGIS Pro and background geoprocessing require 64-bit.
- Backup any custom raster format configuration or registry entries if you’ve modified them.
Step-by-step installation (Windows)
- Download the appropriate MrSID codec/plug-in installer for your OS and ArcGIS bitness.
- Right-click the installer and select “Run as administrator.”
- Follow on-screen prompts; accept license terms and choose default folder unless you have a reason to change it.
- Finish installation and reboot if prompted.
- Start ArcGIS (ArcMap or ArcGIS Pro) after reboot.
Configure ArcGIS to use MrSID imagery
- ArcMap: MrSID should register itself as a supported raster format. Open ArcMap and use Add Data to navigate to .sid files. If it doesn’t appear, check ArcMap’s raster format registration or re-run installer as admin.
- ArcGIS Pro: Add Data > navigate to .sid files. Pro uses 64-bit runtime; ensure you installed the 64-bit codec.
- If working with mosaic datasets: create a mosaic dataset in a file geodatabase and add .sid rasters using Add Rasters To Mosaic Dataset tool; ensure raster type settings are correct for MrSID.
Example: To add MrSID to a mosaic dataset, open ArcToolbox > Data Management Tools > Raster > Mosaic Dataset > Add Rasters To Mosaic Dataset, choose Raster Type = Raster Dataset, and browse to .sid files.
Troubleshooting common issues
- Cannot see .sid files in Add Data: confirm installer matched ArcGIS bitness and was run as admin; try repairing installation.
- Slow rendering or tearing: enable pyramids or overviews in your mosaic dataset; ensure disk/IO is not the bottleneck.
- Georeference mismatch: verify .sid includes correct geotransform; use Raster > Projections and Transformations tools to define or project as needed.
- Licensing errors: some MrSID SDK components may require separate licensing for advanced write features; reading should be supported by the codec without extra license.
Quick fixes:
- Reinstall codec matching bitness.
- Clear ArcGIS cache (Geoprocessing > Options or manually delete cache folders).
- Convert problematic .sid to GeoTIFF with GDAL or LizardTech tools to test file integrity.
Performance tips for large MrSID datasets
- Use mosaic datasets and overviews so ArcGIS fetches only needed resolution tiles.
- Store imagery on fast local SSDs or a fast NAS; avoid high-latency network shares when possible.
- Use proper pyramids/overviews and set the cache tiling scheme to match display scales.
- Limit simultaneous layers and use layer timeouts for web services.
Converting MrSID (optional)
If compatibility issues persist, convert .sid to GeoTIFF or Cloud-Optimized GeoTIFF using GDAL (gdal_translate) or Extensis/LizardTech GeoExpress tools.
Example gdal_translate command:
gdal_translate -of GTiff input.sid output.tif Verification checklist after install
- Open ArcGIS and add a .sid file successfully.
- Zoom/pan and confirm imagery displays at multiple scales.
- Add .sid to a mosaic dataset and build overviews if needed.
- No errors in ArcGIS log related to the MrSID codec.
When to contact support
Contact Extensis/LizardTech support if installer errors persist or if you require write/creation capabilities beyond reading. Contact Esri support for ArcGIS-specific integration problems or persistent crashes tied to raster handling.
Installation, configuration, and troubleshooting steps above should get ArcGIS 3D Analyst reading MrSID imagery reliably. If you want, I can provide exact download links, platform-specific installer filenames, or a scripted deployable installer sequence for enterprise rollout — tell me your ArcGIS version and OS.
