Defining and Executing Analyses

To perform a new analysis:

1. From the first top drop-down list, select Create new option.

   Create new is a default option. If no queries were performed, only the Create new value is available.

2. From the Select features in drop-down list, select the feature class for which to perform analysis.
3. Set the analysis parameters:
   1. Check Where filter is to perform an attribute query and to set the required parameters.
   2. Check Spatial filter to perform a spatial query and to set all the required parameters.

   Available spatial and attribute parameters and operators may vary depending on the data source type. The features can be filtered spatially with current map window, drawn geometry and selected features using available operators (for example intersects, overlaps, touches, contains, disjoint, crosses etc.).

4. Type a name for the analysis layer, and set the style in which the results should be presented on the map.
5. In the Display field, specify the query name. This name is visible in the Map Content tab.
6. To change the style in which the analysis results are displayed on the map, check With style and click . If the style is not defined, the data is presented with a default style.
7. Click Execute to perform an analysis.

   Data appears in the map window and in the Map Content tab. Response time depends on the quantity of data that is loaded.

• When performing attribute queries on data coming from WFS service, an additional IN and NOT IN operators are now available in User Interface.
• IN and NOT IN operators are not a part of neither OGC WFS nor OGC Filter Encoding specification. They were introduced in the User Interface for practical reasons and in case of WFS they are implemented as multi-level OR queries. Values should be comma separated in the input field.
