Geomap: Add support for logical operators

[muling]

Need to add some business logic to the style rules for the map markers. It doesn't seem like this is currently supported.

We would like to do something like this:

  style: {
    rules: [
      new OpenLayers.Rule({
        filter: new OpenLayers.Filter.Logical({
          type: OpenLayers.Filter.Logical.AND,
          filters: [
            new OpenLayers.Filter.Comparison({
              type: OpenLayers.Filter.Comparison.EQUAL_TO,
              property: 'Data Available',
              value: 'Yes'
            }),
            new OpenLayers.Filter.Comparison({
              type: OpenLayers.Filter.Comparison.EQUAL_TO,
              property: 'Operation Schedule',
              value: 'Continuous'
            })
          ]
        }),
        symbolizer: {
          strokeColor: 'red',
          fillColor: 'red',
          pointRadius: '6',
        }
      })

@jvanulde please answer

[jvanulde]

@muling this is in progress.

[jvanulde]

@muling we have something working now. Can you send me a sample file with some rules you need implemented? That way we can test against your requirements.

[muling]

You mean the config rules file? Or can I just send you a plain description of the rules?

[jvanulde]

Plain description will be sufficient. As well as a datasource/dataset that you intend to apply them too.

[muling]

Config rules:
If schedule is continuous AND data_availabe=yes, then display green circle
Else if schedule is continuous AND data_availabe=no, then display red circle
Else if schedule is seasonal AND data_availabe=yes, then display a green square
Else if schedule is seasonal AND data_availabe=no, then display a red square

Sample Dataset (up to 8000 points):
Table headings:
Station Name,Province,Station Number,Data Available,Operation Schedule
ABITAU RIVER ABOVE CUMING LAKE,SK,07QC005,Yes,Continuous
ABITIBI RIVER AT ONAKAWANA,ON,04ME003,Yes ,Continuous
ADAMS LAKE,SK,11AB095,No,Seasonal
ADAMS RIVER NEAR SQUILAX,BC,08LD001,Yes,Continuous

The lat/lon for each point would be passed in somehow too.

Thanks @muling that helps. So we have it working based on the psuedo-rules provided. Please see the screenshot below. We have some testing to do still but I am hoping we can push the update soon.

Result:

For you reference here is the configuration:

[muling]

Is it possible to use our own icon? What shapes are available?

[jvanulde]

You can use your own symbols. Or one of the predefined ones: "star", "cross", "x", "square", "triangle", and "circle" as value for the graphicName property of a symbolizer.

Can this issue be closed?

[muling]

We haven't tested it ourselves yet, but you can close it.
