v6.1.0

v6.1.0 (2023/12/29)

See v6 to v6.1 migration guide

This release focuses on raster improvements including a switch to a global equal area projection for raster analysis, and support for calculating raster area overlap and 10 others in addition to the existing sum metric. See the full list on the Concepts page.

Precalc now calculates 4 metrics for every datasource and geography combination: count, valid, sum, and area.

🚀 New Feature / Improvement

• Use equal area projection EPSG:6933 for rasters internally, reprojecting on import.
• Add getRasterBoxSpherical() function providing bounding box of equal area raster in lat/lon coordinates.
• Add toRasterProjection() function that reprojects a feature (such as a Sketch or a Geography polygon) to the projection of the raster.
• Add high-level overlapRasterArea() and overlapRasterSum() toolbox functions
• Add high-level rasterMetrics() toolbox function that uses rasterStats() function and converts to metric objects.
• Add low-level getArea() and getSum() toolbox functions
• Add low-level rasterStats() toolbox function with access to 12 raster stats including area() calculation. Returns metrics for all bands with band number in the class ID.
• Add low-level rasterStatsToMetrics() function for converting from geoblaze stats objects to Metric objects.

🗑️ Deprecated code

• overlapRaster - replaced with rasterMetrics which is multi-band capable
• overlapArea - use a Geography with overlapFeatures
• overlapSubarea - use a Geography with overlapFeatures
• flattenSketchAllId - unused
• toShortSketches - unused
• getSketchCollectionChildIds - unused

🐛 Bug Fix

🏠 Internal

• Upgrade to geoblaze 2.6 which adds performance improvements in all use cases
• Migrate template-blank-project raster function to use rasterStats()
• Add Proj.4 wrapper that loads EPSG:6933 projection.
