Working with raster data is becoming increasingly resource-intensive. The volume of satellite and aerial imagery continues to grow, along with new data sources and use cases. As a result, organizations need faster access and more flexible storage approaches.
A common solution is to keep large raster datasets in external S3-compatible storage, while connecting them to GIS systems on demand.
NextGIS Web now supports this workflow natively.
NextGIS Web introduces a new resource type: S3-based raster storage. It allows you to connect external S3 buckets and use their contents directly in your Web GIS, as well as store new rasters in the same storage.
This means you can both read and write raster data without moving it into the internal storage of NextGIS Web.
Reduced server load
Large raster datasets remain outside the NextGIS Web instance and do not consume local storage.
Infrastructure flexibility
You can use any S3-compatible solution, including AWS S3, MinIO, or others.
On-demand access
Raster data is accessed when needed, without preloading entire datasets.
To create an S3 raster storage resource, specify:
Once configured, you can:
Raster data stored in S3 can use any coordinate reference system. NextGIS Web supports custom CRS definitions, ensuring correct rendering and processing.
This makes the approach suitable for a wide range of applications, including cadastral systems, environmental monitoring, and scientific workflows.
S3-based raster storage in NextGIS Web provides a practical way to:
If you already use S3-compatible storage, integration with NextGIS Web is straightforward and requires minimal setup.
