Spatial Integration is a geospatial and geoscience 3D visualization desktop environment from Four Winds Technology. It is currently in Early Access and is available for Windows and Linux. Its focus is bringing DEMs, LiDAR, imagery, boreholes, point data, external 3D models, and volume data into a unified 3D scene for viewing. It also offers a free Geoscience for QGIS plugin to fill gaps in QGIS around borehole and geoscience workflows.
Its core design centers on high-performance graphics and large-scale data handling. It uses the Vulkan graphics API, and the interface borrows slide-out control panels from the gaming industry to keep as much screen space as possible dedicated to the data. Large DEMs and imagery are loaded on demand via background paging, allowing users to zoom from global SRTM data down to centimeter-level LiDAR. It supports multiple image overlays, transparency blending, and imagery streaming.
The geoscience features are a particular strength, with support for borehole traces, lithology and assay discs, downhole bar and line charts, real-time isosurfaces for volume data, and block threshold display. Volume data can come from formats such as VTK, UBC, Loke, and DICOM. For coordinates, it supports projected and globe views, plus on-the-fly reprojection across thousands of CRS options. The QGIS plugin supports borehole desurveying, downhole data processing, structural measurement conversion, local grid creation, and more, and can be installed through the QGIS plugin manager.
The Community Edition is free and suitable for small tasks or occasional 3D visualization. The Professional edition costs AUD 1500/year and is aimed at day-to-day professional use. Differences between the two include the number of imagery overlays, imagery streaming, volume data, borehole groups, and borehole charts. Geoscience for QGIS is free.
For documentation, the application includes F1 help, while the website provides tutorials, demo videos, and sample project data. Practical learning materials are fairly complete. However, there is no clear information about an API/SDK, automation, enterprise deployment, or SLA.
Its strengths are clear positioning and a strong fit for mining exploration, earth sciences, and GIS 3D viewing scenarios. Large-data paging, transparent rendering, mixed CRS handling, and the QGIS plugin combination all provide practical value.
The drawbacks are that it is still in Early Access, the Windows installer is not digitally signed, no MacOS download is listed, and upgrading to Professional requires contacting the team by email. Procurement and enterprise administration are not very self-service. There is also no stated open-source, self-hosting, or API capability.
The collected text does not provide information on access from mainland China, payment methods, or local agents, so this remains unknown. Users in China should first test access to the official website, downloads, and YouTube tutorials. If access is restricted, alternatives to compare include QGIS, ArcGIS Pro, Cesium, ParaView, CloudCompare, or specialized geoscience software.
