## What problem does it solve? This Skill helps analysts access and inspect remote geospatial data without downloading large files, leveraging GDAL's VSI prefixes to read from HTTP or S3 endpoints directly.
## Core Features & Use Cases
### Quick Start Inspect a remote dataset using /vsicurl/ and summarize its layers with ogrinfo.

To read remote geospatial data without downloading, use GDAL VSI prefixes like /vsicurl/ for HTTP endpoints and /vsis3/ for S3. This streams data on demand, letting you inspect or convert large datasets directly from remote sources.
Yes, you can inspect remote formats like Shapefile, GDB, and GeoTIFF using ogrinfo. Prefix the remote URL with /vsicurl/ or /vsis3/ to read dataset layers and attributes directly without local downloads.
Convert remote GeoTIFF to GeoParquet by running ogr2ogr with the input path prefixed by /vsicurl/ or /vsis3/. This avoids downloading large source files, outputting the converted GeoParquet, GeoJSON, or GeoPackage format locally.
Yes, GDAL VSI supports reading from private S3 buckets using /vsis3/. You must provide appropriate credentials to handle edge cases like authentication, streaming output, and mixed geometry types during remote access.
The best way to access large remote geospatial datasets without downloading is using GDAL VSI prefixes. Tools like ogrinfo and ogr2ogr read data on demand over HTTP or S3, enabling inspection and conversion efficiently.
Yes, you need a GDAL installation built with VSI support to use prefixes like /vsicurl/ and /vsis3/. This enables direct streaming access and conversion of remote GDB, Shapefile, GeoTIFF, and GeoParquet datasets.
