Cadcorp SIS and GML

• OS MasterMap™– Dedicated parser– Hardwired to OS MasterMap™ Schema– Cadcorp SIS OS MasterMap™ Manager

• Loads and indexes up to national coverage– e.g., PostGIS and (Cadcorp-proprietary) “OS

MasterMap™ Database” (ODB) file: ~4½ days

• Not OS MasterMap™– Generic, XML Schema-aware parser


Cadcorp SIS and TOP10NL (i)

• Multiple geometry elements– SIS “Group”?

• Not easy to edit

– Geometry Collection?• Semantically different, and difficult to decompose on

re-export

– Split into multiple features?• Humpty Dumpty problem

– Change the Schema?• One geometry/id per feature


Humpty Dumpty

Humpty Dumpty sat on a wall.

Humpty Dumpty had a great fall.

All the king's horses and all the king's men

Couldn't put Humpty together again.


Humpty Dumpty (reprise)Homme petit d'homme

petit, s'attend, n'avale.Homme petit d'homme

petit, à degrés de bègues folles.

Anal deux qui noeuds ours, anal deux qui noeuds s'y mènent

Coup d'un poux tome petit tout guetteur à gaine.

http://en.wikipedia.org/wiki/Humpty_Dumpty


Cadcorp SIS and TOP10NL (ii)

• Styled Layer Descriptor (SLD)– Wow– Forty-one <sld:Rule> elements– Many, many string comparisons– No scale thresholds– On-the-fly rendering potentially slow

<sld:Rule> <sld:Name>spoorweg-enkelspoor</sld:Name> <sld:Title>Spoorweg enkelspoor</sld:Title> <ogc:Filter> <ogc:And> <ogc:PropertyIsEqualTo> <ogc:PropertyName>top10nl:typeSpoorbaan</ogc:PropertyName> <ogc:Literal>trein</ogc:Literal> </ogc:PropertyIsEqualTo> <ogc:PropertyIsNotEqualTo> <ogc:PropertyName>top10nl:fysiekVoorkomen</ogc:PropertyName> <ogc:Literal>in tunnel</ogc:Literal> </ogc:PropertyIsNotEqualTo> <ogc:PropertyIsEqualTo> <ogc:PropertyName>top10nl:aantalSporen</ogc:PropertyName> <ogc:Literal>1</ogc:Literal> </ogc:PropertyIsEqualTo> <ogc:PropertyIsEqualTo> <ogc:PropertyName>nen3610:status</ogc:PropertyName> <ogc:Literal>in gebruik</ogc:Literal> </ogc:PropertyIsEqualTo> </ogc:And> </ogc:Filter> <sld:LineSymbolizer> …<sld:/Rule>


Cadcorp SIS and TOP10NL (iii)

• If…• Hard-wired parser and exporter• Styling applied by parser• Dedicated editing application

– OS (GB) CITF– IHO S-57

• Use additional metadata/feature attributes to help solve the Humpty Dumpty problem


Cadcorp SIS and TOP10NL (iv)

• Or is there a Humpty Dumpty problem?• Is editing a “normal” use-case?

– Definitely not with OS MasterMap™

• Consider having multiple application schemas– Internal/editing– External/reference/backdrop– Etc.
