Converting Catalogs to GML/XML Format

Catalogs to GML/XML Format

Downloaded catalogs are converted to GML format.

This allows us to Have a common data format Use native XML Databases like Xindice or

Sleepycat.

GML Format GPS Data

<GPSData>  <Date DecimalYear="2001.6427">01AUG23</Date>   <Estimate uom="cm">-5.20310199631932</Estimate>   <Sigma uom="cm">0.766566081927471</Sigma>   <Site>7ODM</Site>   <Component>RAD</Component> </GPSData>

GML Format Earthquake Data<Catalog> <Latitude> <degrees>34</degrees> <decimalMinutes>7.80</decimalMinutes> </Latitude> <Longitude> <degrees>117</degrees> <decimalMinutes>59.58</decimalMinutes> </Longitude> <Quality>D</Quality> <Magnitude uom="r">0.0</Magnitude> <Depth uom="mm">6.0</Depth> <NPH>7</NPH> <RMS>0.07</RMS> <EventId>3358386</EventId> <TimeOfDate> <Date Year="1932" Month="01" Day="01">1932-01-01</Date> <Time Hour="23" Minute="52" Second="07.87">23:52:07.87</Time> </TimeOfDate></Catalog>

Add GML Data to XML Database

Query Construction for XML DB Search Queries for both GPS and Earthquake

catalog searches are generated by our system.

Sample Query:

/GPSDataContainer/GPSData[Site[text()='7ODM'] and Component[text()='LAT'] and Date[@DecimalYear>=2002] and Date[@DecimalYear<2004] and Estimate[text()>=0] and Estimate[text()<=3.2]]
