Re: [geomesa-users] LineString data query problem

[Emilio Lahr-Vivaz <elahrvivaz@xxxxxxxx>]

Hello,

I don't see anything obviously wrong with your code snippets, it looks like it should work. Do you see data in the underlying HBase tables after doing your insert? If so, you should check the logs for errors, and also try enabling explain logging to see what is actually being executed by your query:

Thanks,

Hi,team.

I am using geomesa with HBase to do some testing. In the process I found that I can't use bbox to query data when I use XZ index.

This is the code I declare schema:

``

attributes.append("taxiId:String,");
 attributes.append("*geom:LineString:srid=4326");
sft = SimpleFeatureTypes.createType(getTypeName(), attributes.toString());

``

This is the code I am storing data for:

``

builder.set("taxiId", key);
StringBuilder pointStringBuilder = lineById.get(key);
builder.set("geom", "LINESTRING (116.36919 39.90568,116.32919,39.91568 ,116.33919,39.92568)");
builder.featureUserData(Hints.USE_PROVIDED_FID, Boolean.TRUE);
 features.add(builder.buildFeature(key));

``

This is the code I am querying for data:

``

String bbox = "bbox(geom,115, 35, 120, 45)";
queries.add(new Query(getTypeName(), ECQL.toFilter(bbox)));

``

The result obtained after running the query statement is empty. What is wrong with it? Is there any relevant information to check?
