## Performance evidence update / 18 September 2026 MODALITY PERFORMANCE / EVIDENCE REVIEWED 18 SEPTEMBER 2026 Define the useful result. Measure the complete job. A modality-specific timing is not yet linked to this guide. There may be supporting engineering measurements in the internal archive. We are reconciling their workload, result quality and comparison conditions before presenting a public chart. A benchmark for an adjacent model does not establish this model’s performance. 01 Resolution & band fidelity 02 Window / region latency 03 Decode & storage cost Include memory, storage, energy and hardware writes # Raster fields | 8DB Product reference.

Capabilities What changes Input to value Alternatives Performance Adoption Related articles Reference Start with the operations your question needs. Typed scalar raster/grid representation Preserved regular layout and values Source and related-record context Documented product scope, reviewed 17 September 2026. The underlying build and deployment must be qualified for your application. Raster typing does not prove support for every geospatial file format, reprojection or analysis operation. Check NoData, units, resolution, georeferencing and import/export behaviour explicitly. Connected native models Keep the next question within reach. The useful addition is context around the cells: a field can be inspected beside the capture event and associated observations. A grid’s shape and value semantics remain explicit.

A file-size comparison alone does not establish a faster or more accurate field-analysis workflow. Compare a realistic alternative. GDAL documents a broad raster driver ecosystem. It is an interoperability/processing baseline, not a competing database with identical responsibilities. Avoid implying that a typed grid replaces that entire ecosystem. GDAL raster drivers (https://8braid.com/modalities/https://gdal.org/en/stable/drivers/raster/index) Compare equivalent outputs and required guarantees, including the simplest single-product alternative where one exists. A specialist may remain the better fit when its operators, ecosystem or operational maturity are decisive. Combining native models becomes valuable when your actual question crosses them. Performance & resources Measure the work that delivers the answer. Cell/layout and NoData fidelity; supported formats; region-read latency; input preparation; bytes transferred/stored; complete map freshness. This draft does not assign a new speed ratio or score to this modality. Existing measurements and source leads are retained in the evidence programme; a qualified public result must identify the particular operation and path tested. Explore the published benchmark evidence (https://8braid.com/benchmarks) What belongs inside the timer and resource budget? For input-to-value testing, declare the input state and the consumer-ready output first. Include parsing, derivation, storage/protection, index readiness, querying, result assembly and delivery as applicable. Identify amortized setup and any work deferred past the finish line. Report database-stage and full-job results separately. Do not add unrelated medians or p95 values, or multiply component speedups into a claimed workflow result. Energy needs measured joules; reduced handoffs alone do not establish a saving. Choose the path that fits your deployment. Verify the supported API/SDK, data format, persistence and indexing behaviour for the release you plan to use. Match the operation-by-modality protection profile and device qualification to the workload.
