1 Rad Map fr Implementatin f Harmnized Vertical Reference System 8 February 2018 A. OVERVIEW This is a Draft Rad Map describing the transitin t the Harmnized Vertical reference System within the Baltic Sea. The purpse f the Rad Map is t give guidelines fr BSHC member cuntries t make the natinal transitin plans and t make pssible fr the CDWG t mnitr and harmnize the transitin within the Baltic Sea regin. A.1 Final utcme Harmnized vertical reference in use within the whle Baltic Sea by the year A.2 Visin Transitin t S-100 envirnment and usage f new S-100 based prducts will happen in the future, S-101 based ENCs expected t be available and in use by 20XX.

Questinnaire t BSHC Member States n their implementatin status f the transitin t a Harmnised Vertical Reference, Baltic Sea Chart Datum Last three questins cncerns GNSS-augmentatin/crrectin services used in member states. Please return t Mr. Jyrki Mnnen by (jyrki.mnnen@liikennevirast.fi) at the latest by 26 January Member state Sweden Date f reply Pint f Cntact Thmas Hammarklint, Hydrgraphic Office (HO), Swedish Maritime Administratin (SMA) Thmas.Hammarklint@Sjfartsverket.se 1. Are all the decisins dne t implement the Baltic Sea Chart Datum 2000? The change f chart datum in Swedish fficial nautical chart prtfli; the Chart Imprvement prject (Sjökrtslyftet) is included in the Swedish HO Visin 2020 (Målbild 2020), apprved and decided 2014 f SMA HO management. Chart Imprvement prject: The vertical reference and castline will be updated and referred t Baltic Sea Chart Datum 2000 (RH2000) (BSCD2000) in all Swedish charts, except thse cvering inland waters, befre the end f Lakes cvered f fficial charts will be taken care f in similar way befre the end f Swedish Maritime Administratin (SMA) and Swedish Meterlgical and Hydrlgical Institute (SMHI) have a cperatin agreement cvering this area f respnsibility. Transitin t the new vertical reference fr the water level will take place during the same perid. Discussins with SMHI n a specific date fr the transitin int BSCD2000 are n-ging. It is pssible t tgether with ther cuntries cncerned agree n this. The pssibility fr the user t chse between mean sea level and BSCD2000 will be implemented. In the EU-financed prject FAMOS, SMA and SMHI will harmnize and upgrade the Swedish water level netwrk ( ), including new sensrs fr 50 statins. All water level data will be presented in BSCD When the decisins has been dne r planned t be dne? Year What are the natinal decisive rganizatins? Swedish Maritime Administratin (SMA) includes Hydrgraphic Office (HO) and is representing Sweden in IHO and is als respnsible fr fficial Swedish nautical charts.

6 SMHI and SMA in cperatin: reference datum fr water level and publishing water level infrmatin. Swedish Meterlgical and Hydrlgical Institute (SMHI) are amng ther things respnsible fr this INSPIRE Directive theme and respnsible fr the master natinal water level netwrk and als a member f BOOS. SMA has been a member f BOOS since May What is the natinal status f implementatin? 2.1. What actins have already been dne? All new hydrgraphic surveys started July 1, 2013 r later refer t BSCD2000. The Swedish depths database (DIS) was transfrmed t the Swedish realisatin f the harmnized vertical reference (BSCD2000) All new charts in inland waters prduced 2008 r later refer t BSCD2000 with added ffset adapted fr each lake. In September 2015 the Chart Imprvement prject started. Up t this date 10 paper charts and equivalent ENCs have been updated t BSCD2000. In areas where n mdern surveying has been perfrmed and nly ld analgue depth data is available these fair sheets has been scanned, transfrmed and upladed int DIS (referring t BSCD2000). Digitalizatin has been finalized Vertical/Height infrmatin in the data base Pseidn, string nautical bject including light huses, refer t BSCD2000. All invlved water level statins is cnnected t the BSCD2000 netwrk. All water level data recrded at the statins wned by SMHI is stred referring t BSCD What actins have been planned t be executed and what is the schedule? See answer Are the relevant natinal cntacts and interest grups defined? 3.1. What are the essential natinal interest grups in Yur cuntry? Swedish Maritime Administratin ( Sjöfartsverket SMA) (including crrespndence with lcal harburs thrugh head f Pilt areas) The Swedish Meterlgical and Hydrlgical Institute (SMHI) The Swedish Natinal Land Survey ( Lantmäteriet LM) The Swedish Transprt Agency ( Transprtstyrelsen TS) The Swedish Transprt Administratin ( Trafikverket TV) The Gelgical Survey f Sweden ( Sveriges Gelgiska Undersökning SGU) The Cunty Administrative Bards ( Länsstyrelserna Lst) 3.2.

Have Yu identified any bstacles r majr issues cncerning transitin t the harmnized vertical reference? 4.1. What are the majr bstacles r issues? The HO has replaced the frmer chart prductin system in There was a temprary disruptin during September 2016 t December 2017 in the Chart Imprvement prject. Infrmatin t the users abut the transitin t the chart datum Baltic Sea Chart Datum 2000 (BSCD2000) is a majr challenge. T change int a new reference datum fr water level t early might cause a misleading understanding abut the true depths What measures has been planned t avid them? Extra time allcated in the plan but the time schedule is tight. The wrk started in the nrthern parts f Bay f Bthnia and the plan fr 2018 is t reach the area suth f Gävle and the area surrunding Gtland. 5. Cnnectins t neighburing cuntries 6.1. Which are the relevant cuntries t cperate? Sweden has bundaries t all ther cunties surrunding the Baltic Sea. T sme extent cperatin is needed with all f them, but in practice handled thrugh BSHC. Sweden (and Denmark) has maritime brders adjacent t Nrway in areas with limited tide. Nrway applies different rules (cmpared t Sweden and Denmark) regarding the chice f reference level. As a result the reference level used in the charts shifts up t abut a half meter alng the brder. There is need f an agreement between Sweden, Nrway and Denmark regarding the delimitatin and shift f Chart Datum twards the Nrth Sea. Sweden has an actin within the Nrdic Hydrgraphic Cmmissin t invite Denmark and Nrway fr this Are the needed pints f cntacts already knwn? Necessary pint f cntacts is knwn. Imprtant t cntinue the dialgue between CDWG/BSHC and BOOS t get the water level perating institutins in the transitin t the new reference What actins have been agreed with the relevant cuntries (e.g. synchrnising plans and schedules)? CDWG RadMap Page 7 (8) 8 February 2018

8 There is n synchrnising dne in regards t time schedule. It is up t each and every member state t implement the agreed vertical reference system (EVRS) and Chart Datum. All steps twards EVRS will imprve the existing situatin. Sweden has a fruitful exchange f infrmatin and experiences with Finland cncerning harmnizatin within the FAMOS prject and the Chart Imprvement prject. 6. Are there any needs fr supprt frm BSHC? Supprt the dialgue with Nrway and NSHC in rder t handle the reference level difference at the brder between Sweden and Nrway ( and preferably als between Denmark and Nrway). That kind f dialgue will prbably supprt any future agreement cncerning the reference level fr high-reslutin bathymetric data in Eurpean castal waters. 7. D yu have any ther prpsals r guidance t the CDWG t help and fster the transitin prcess? The Chart Imprvement prject is included in the FAMOS prject and has received EU c-financing frm the Cnnecting Eurpe Facility (CEF Transprt) fr the years Fr mre infrmatin, see: 8. Are yu using GNSS and GNSS augmentatin services fr referring t yur (bathymetric) surveys t the chart datum? In areas with acceptable cverage we are using GNSS with RTK, either frm wn base statins r the SWEPOS Netwrk RTK service prvided by Swedish Land Survey Lantmäteriet. In areas in pen sea with pr cverage r where the height cmpnent is inadequate we nly use the hrizntal cmpnent frm RTK r Netwrk DGPS frm SWEPOS r IALA DGPS. Depths are then crrected by tide mdels t the chart datum. 9. What GNSS augmentatin service is used fr hydrgraphic surveys? (If there are several augmentatin services, list all f them.) SWEPOS Netwrk services prvided by Swedish Land Survey, Lantmäteriet and IALA DGPS. 10. T which crdinate system, and vertical reference level/frame the augmentatin service is referred t? (If there are several systems in use, list all f them.) Crdinate system SWEREF 99 TM (extended UTM zne 33). We are using the geid mdel SWEN08_RH2000 t cnvert frm ellipsid height t Swedish natinal reference level RH2000 (BSCD2000). Frm the beginning f the survey seasn 2018 we will use the new geid mdel SWEN17_RH2000, which is calculated frm the NKG gravimetric mdel. CDWG RadMap Page 8 (8) 8 February 2018
