+Before making recommendations on how to standardise New Zealand's DEM/DSM data, LINZ took a brief look at other jurisdictions and how they standardised their DEMs and/or DSMs.
The key areas to look at were
-
-- compression - What lossless compression was most common
+- compression - what lossless compression was most common
- size - width and height of image
- file size - how big each tile is
-- storage type (Tiff/COG/other)
+- storage type (TIFF/COG/other)
