NOAA RNC Chart blank when zooming
NOAA RNC Chart blank when zooming
September 30, 2018 03:09PM
Have downloaded NOAA RNC 11309 and 11312 for Port Aransas / Corpus Christi bay area. As I zoom below 1:60000 around Hog Island, a portion of the raster charts turns white/blank as if there is a detail I haven't downloaded. I don't see another chart detail available le on NOAA website, any ideas what would cause this?

Thx,
Jeff

If you look at the copy of the original chart here: [www.charts.noaa.gov] you can see that the area is overlaid with a chart inset of a different area. That inset is shown in its correct location (seen as 11312_2 in the chart list). The area of inset is rendered in white because that is what the chart data contains.

BSB charts do not have an option of "cutting out a hole" in the coverage. So, the only way to fill this area in would be for NOAA to release another chart (larger scale) that covers the area. I don't see one currently available - but you may want to check directly with NOAA.
