Bottom height map, base map for the Zoute ecotopes Westerschelde 2015

Van de Westerschelde was made an ecotope card in 2015. A salty ecotope map is constructed by merging several layers of information from the intertidal area: soil height map (height and depth), geomorphological map, dry fall duration map, flow map and salt map. The bottom height map is based on lodings (depth) 2015 and laser altimetry (height) 2015. Laser altimetry data combined with singlebeam specialist loading data where the laser altimetry data has been given a higher priority than the loding data. In order to complete the entire ecotope card, it was then supplemented by multibeam landings and additional data on Flemish territory. The single-beam box loads used with recording dates (start and end dates): 0100p1501 16-01-2015 27-01-2015 0200p1501 20-01-2015 20-02-2015 0300p1501 20-01-2015 08-03-2015 0400p1501 25-02-2015 17-03-2015 0500p1501 10-03-2015 22-03-2015 0600p1501 21-03-2015 07-04-2015 1800p1501 23-03-2015 10-04-2015 Additional surveys (multibeam): Sloehaven Vlissingen [ZS Vlissingen Oost 2015-02]: 11/02/15 Outside harbour Vlissingen [ZS Buitenhaven Vlissingen 2015-02]: 11/02/15 Koopmanshaven Vlissingen [0617p1509]: 24/02/15 Ferry port Breskens [1826p1509]: 24/02/15 Commercial port Breskens [0627p1509]: 24/02/15 Terneuzen Braakmanhaven [ZS Braakmanhaven 2015-02]: 03/02/15-04/02/2015 West Buitenhaven Terneuzen [6001p1509]: 24/02/15 Eastoutdoor Terneuzen [6002p1509]: 24/02/15 Old Veerhaven Terneuzen [6006p1509]: 24/02/15 Buitenhaven Hansweert [6206p1501]: 02/03/15 Pass of Terneuzen — Dow Steiger [0438p1501]: 21/04/15-22/04/15 Pass of Terneuzen — Total Scaffolding [0543p1501]: 20/05/15-21/05/15 Port Perkpolder [0232p1501]: 11/08/15 Perkpolder area development [0301p1501]: 30/07/15 Channel High Plates [0646p1513]: 07/04/15-08/04/15 Singlebeam recording: Bathse Spuisluis [0124p1501]: 27/11/15 Data files Flanders: 140422_SK_SA_DL_MB_400_RD_LAT.txt (level between 22/4/2014 and 5/11/2014) 150316_SK_SA_DL_MB_300_RD_LAT.txt (level between 16/03/2015 and 9/7/2015) The routing distance for boxes 0100 to 0300 = 100 m The routing distance for boxes 0400 to 0600 + 1800 = 200 m The singlebeam data is interpolated with digipol.
