Enhancements

• The GeoTIFF raster format is a common exchange format supported by many mapping software suites. However, as an open exchange format there can be different interpretations of the structure and contents of these files across vendors. We previously supported TIFF files containing a 1 band of elevation values, 1 band of color, 3 bands of color (red/green/blue) values and/or an optional 4th alpha band (for blending). We have extended our visualization capabilities to also support GeoTIFF files containing 2 bands of color (1 color, 1 alpha) or 5 bands (3 bands of color, 1 band alpha, 1 band intensity).
• ESRI's Shapefile (SHP) file format stores coordinates as Latitude/Longitude on the WGS 84 ellipsoid (CRS EPSG:4326). However, some 3rd-party software packages will allow storing data in coordinate systems other than this standard. We have updated our visualization pipeline to accept non-standard CRS definitions for this format.

Issues Resolved

• Google KML/KMZ files containing sounding values were causing errors when displayed in Absolute Ocean. This has been fixed.
• When a user clicks more than once to add a visualization to the map, this was causing the visualization to be added to the map multiple times behind the scenes. Among other consequences, removing a visualization from the Layers window appeared to not remove it from the map (it is only removing one of the multiple additions). This has been fixed so a visualization can only be added one time to the map.
• Some windows in the interface were not correctly refreshing when the user session is no longer valid (e.g. session has timed out). These have been fixed.
