![]() ![]() Once the review was complete, the data was then passed on to the Marine Chart Division on October 13, 2021. Given its high priority, the branch elevated the survey in the queue and quickly completed an acceptance review of the data. The team quickly reviewed the data, after requesting some additional metadata and getting the Navy to sign a data release form, and the survey was approved and passed on to HSD’s Pacific Hydrographic Branch on September 15, 2021. A final survey was made available in late August 2021, and was delivered to Coast Survey’s Hydrographic Surveys Division (HSD) External Source Data Team on August 27. The navigation manager worked with the Navy to get a final hydrographic survey of the new channel. This would ensure that new shoreline data was available once the survey was ready for application to the chart. Within the division, the Nautical Data Branch – which handles all incoming source data – made two shoreline update requests to the National Geodetic Survey’s Remote Sensing Division. In order to update the nautical chart, it was determined that a hydrographic survey and shoreline data was needed. ![]() California’s navigation manager contacted the division relaying that the Navy had created a channel to handle civilian traffic for Huntington Harbour and was anxious to have it portrayed on NOAA products. The Office of Coast Survey’s Marine Chart Division is responsible for applying updates to nautical charts. Updating the chart was essential to provide accurate information and, just as importantly, instill confidence to the end users. During this time, the navigation systems of recreational boaters would show them “driving” over land. The channel opened to traffic in the Spring of 2021, while the Navy was still conducting final dredging and shoreline reinforcements. Southeast of Anaheim Bay is Huntington Harbour – a large community of homes with waterfront access and several marinas with numerous recreational boaters. In operation since 1944, the station has evolved into the Navy’s primary West Coast installation for ordnance storage and loading of munitions on medium-sized naval vessels. Just down the coast from the Port of Long Beach in California, is Anaheim Bay and Naval Weapons Station Seal Beach. Unless there has been a catastrophic event, these changes in land are usually the result of human interaction. What doesn’t happen quite as often are changes to land along the coast, altering the way inlets, harbor entrances, and river mouths appear from a bird’s eye view. The bottom of a water body is changeable by nature, thus hydrographic surveys are constantly necessary to show contemporary depths in a given body of water. The large majority of these updates consist of revisions to water depth information. Thank you.Nautical charts are updated with the most current information available through several processes and workflows within NOAA’s Office of Coast Survey. You need to press the button in the top left that says ‘switch to offline mode’.Īfter viewing the tiles instantaneously after downloading, please consider editing your review. Hi, after downloading the maps the tiles load instantly. It’s really quite cumbersome (esp if you want to download multiple maps). So thank you for taking the time to respond, but I’d suggest you revisit this downloading process. This should be streamlined, getting rid of all of those modal dialog/alert boxes. In the developer response, he says “after downloading the maps, the tiles load instantly.” But downloading multiple maps is a clumsy affair. This app has plenty of data available, but it’s unwieldy. ![]() the three modals per download meant that I had to sit down in front of the iPad for ~20 minutes to download all of the maps) and that didn’t solve it. you should be able to just tap on maps in the list to start the downloads and let them progress concurrently. I tried downloading all of the maps, too (which, as an aside, was a very frustrating exercise. It’s so painful as to render the app unbearable. This slow tile-by-tile rendering of the image repeats every time I zoom or move around on the map. If you have any questions, please email RyanĪs I pan around, it’s taking my iPad Pro a really long time to render a particular screen. ![]() Users should consult the Code of Federal Regulations for current federal chart carriage requirements.
