17 April Teamsurv data in Base Platform April 17, 2017By Tim Thornton Base Platform Base Platform, GeoTiff, bathymetry 0 TeamSurv's data is now available in the Base Platform data portal for the trial areas of the Channel Islands, WaddenSee, Balearics and Mauritius. This data is being made available as open data as part of the Base Platform project, and is freely downloadable by anyone who is interested, or can be accessed as a WMS layer that can be viewed online or in most GIS packages. We will shortly have all of our processed data available in the portal, where it can be purchased for commercial use. Related Posts TeamSurv at Jersey Boat Show TeamSurv will exhibiting at the Jersey Boat Show over the May Bank Holiday, 29 April - 1 May. We will be showing the latest depth data for the Channel Islands produced by us and our partners in the Base Platform project, and also showing charts for the islands, highlighting how poorly they have been surveyed - most of it is lead line data, some going back to the 19th Century. Drop in and see what we are doing, and also if you are a boat owner how you can help by logging data for TeamSurv. On the day after the show we will be talking to organisations in the Channel Islands that could be interested in using the data we're producing, and also calling in at marinas, yacht clubs and so on to drop off some leaflets about the project. If you'd like to meet up, let us know. TeamSurv at IHO Assembly TeamSurv will be attending the IHO Assembly in Monaco over 24 - 28 April, demonstrating both their crowd sourced bathymetry and the Base Platform project to the delegates from all IHO member states. Crowd sourced bathymetry is becoming a hot topic at the IHO, as the IHO's crowd sourced bathymetry workgroup (to which we are an expert adviser) gets close to publishing its guidebook on crowd sourced bathymetry, and we are seeing a number of hydrographic offices begin trials of crowd sourced projects. Noonsite supports TeamSurv Noonsite, a popular web site for blue water cruisers wanting to chart or plan their next voyage, realises the need fr better quality charts, especially as sailorts head off the beaten track. They have just published this article, recommending the users of their site to sign up and contribute to TeamSurv. Maritime Journal on TeamSurv The Maritime Journal has published an article on TeamSurv and the need for better bathymetry. You can see the online version on their website. IHO CSBWG Meeting The IHO's CSB Workgroup met in Rostock, Germany on 7/8 November. I couldn't get there for the meeting, but participated remotely, thanks to Google Hangouts. Most of the activity in the meeting was centered on producing the IHO's guide book to crowd sourced bathymetry, which also links in to extending their existing DCDB repository for research vessel tracks to include crowd sourced data. In the background, NOAA are also extending the DCDB portal to incorporate crowd sourced data. The underlying model is that a number of "Trusted Nodes" - of which TeamSurv will be one - contribute data to the repository, thereby relieving the IHO from the burden of recruiting and managing vessels. But this also means that the success of the project depends very much on their being organisations willing to act as an (unpaid) trusted node, gathering data and donating it to the IHO. Much of the earlier work has centered on the technicalities of what data to collact, and what format to use to upload it to the DCDB. This time there was more focus on the ... Visit us at Ocean Business TeamSurv are exhibiting at Ocean Business on stand A21, along with DLR and IsardSAT as part of the Base Platform project, with another partner EOMap next door. Base Platform is looking at producing bathymetry using both our crowd sourcing and various types of satellite derived bathymetry. Entrance to the exhibition is free, so please come in and say hello. Also, on Thursday there are two workshops, first of all at 1500 by EOMap specifically on their technology, and then a general one on Base Platform at 1545. These are both held at Node Room 1, 064/03, Level 4. EOMap offer optical satellite derived bathymetry, where they calculate the depth from the colour shift in the water - this works in waters up to about 25 meters depth. DLR use SAR (synthetic aperture radar) in two ways. First, they detect the boundary between water and land and, knowing the time, use a tidal model to work out the height of tide, thereby giving them a contour. Secondly, they select images where there are significant regular waves, and calculate the depth from how ... Comments are closed.
