NewIngest: progress commit
fix bug rows/cols were switched
Cleaned up the new ingest codepath
- Moved NewIngest code to Ingest and removed NewIngest.
Ingest now uses geotrellis to warp and crop the tiles
- Added convenience method metadataForBaseZoom to PyramidMetadata
- reverted changes to Encoder - the geotag refactoring has to wait
for another day, another commit
Replaced the concept of Bounds with Extent in geotrellis-spark
1. Removed type Bounds. Use Extent instead.
2. Renamed methods/fields tileBounds/pixelBounds with tileExtent/pixelExtent
3. Renamed variables accordingly
Merge remote-tracking branch 'upstream/master' into ingestchanges
Merge pull request #723 from ameetkini/ingestchanges
