1 Geografisk information Förslag till svensk standard för vattensystem Remisseminarium 25 april 2013 Standardens applikations och GML-schema

2 Innehåll Översikt UML vad är det? Applikationsschema GML schema

3 Översikt o Uppbyggnaden av vattensystem i delar och relationerna mellan delarna, t.ex. vattenförekomster, vattenplatser och hydrologiska områden o Hur vattensystem kan representeras i olika detaljeringsnivåer o Vattensystemet som ett flödesriktigt nätverk med beskriven geometri och topologi o Unika identiteter, företeelseidentiteter, hydrologiska koder och vissa centrala attribut o Hur uppdatering av informationen hanteras, inklusive versionshantering och giltighetstid o Metadata, specifikt kvalitet o Geometrier i flera dimensioner, referenssystem

4 Innehåll i standarden odefinitioner ohierarkier onätverk ohierarkier i nätverk oidentifierare oversionshantering ogeometri ISO and GML otemporal ISO ometadata ISO oapplikations schema uses ISO 19109

12 Identifierare

13 Attribut Attribut beskriver en egenskap för företeelsen Varje klass kan ha attribut Attribut ärvs Attribut Varje attribut kan anges av ett eller flera värden. (till skillnad från shapefiler) Attributvärden kan vara komplexa (egna datatyper) realiseras som hjälptabeller.

14 En sjö har flera data kopplade till sig Exvis ID Namn Djup Geometrisk representation Punkt Line Surface Solid

15 Geometri Geometri är ett attribut som andra. Anges som en komplex datatyp WS_Geometry o Metadata o GM_Geometry o GM_Point o GM_Line o GM_
