1 Ny Nationell marktäckekartereing- CadasterENV För miljöövervakning och landskapsanalys Kartografiska sällskapet

2 Bakgrund Finansierat av ESA Två CadasterENV-projekt (Sverige och Österrike) Nov Okt/Nov 2015 Svenska användare:

3 Projektmål Framtagande av ett system för att: Kartera marktäcke/markanvändning i två olika skalnivåer Övervaka förändringar Uppfylla flera svenska användares databehov Skalnivåer: 10 meters upplösning för att kartera marktäcke och identifiera förändringar på nationell och regional nivå (HR) 2 meters upplösning med fokus på marktäcke och förändringar i städer med behov av underlag för lokal planering (VHR)

25 Nya indata - Sentinel-2 Förväntade förbättringar när bilder från Sentinel-2 finns tillgängligt: Högre klassningsnoggrannhet; Lövinslag och lövskogar Vatten och vattenvegetation (medelvattenstånd) Öppen våtmark En mer detaljerad klassning Naturtyper i öppen mark baserat på fältskikt (t.ex. gräsmark och hed) Skogstyper med lövträd (t.ex. ek- och askskog) Naturtyper i fjällen Identifiera långsamma förändringar Övergång från jordbruksmark till annan öppen mark Övergång mellan olika trädslagsblandningar Igenväxning En mer kostnadseffektiv kartering Större scener Fler scener (fler molnfria data får önskad registreringstidpunkt)
