Axional Geospatial can map multiple layers of independent data sources. For instance, a company might be interested in cross-referencing different data on a map, such as the location of its customers and the socioeconomic data (such as average income or age) of their area (state, district, postal code, etc.)

For each data layer, certain attributes can be set:

• Label: A label identifying the layer will appear in the legend.
• Visibility zoom range: Minimum and maximum zoom range in which the layer is visible. Outside the range, the layer becomes invisible.
• Initial visibility: Even if a layer is in the visible range, it can be set to hidden by default. The user can set it to visible when needed.
• Category: Layers can be grouped into categories.
• Geometry rendering types: Usually, spatial databases have three kinds of geometric types: point, line and polygon. However, due to the nature of the data it can sometimes be more useful to draw geometries in a special format.
• Heat map: Suitable for mapping density.
• Clustering: Useful for a large number of markers.
• GPS tracing: The ability to map a path of GPS points.
• Symbology: Allows the definition of symbols on the map. This may include colors, opacity, borders, image markers (when geometries are points), etc.
• Info window: The text that will appear in a box when clicking a geometric type. The text can be a static string or a template with references to columns in the row clicked; it may also call an XSQL script in the server, returning HTML code.
• Tracking cursor: A tracking cursor is another SQL query used to iterate layers. When a tracking cursor is defined, the layer SELECT statement should have variables in the SQL condition. For each row returned by the tracking cursor, the SQL layers are executed with variables tracked by the cursor. That means that for every row in the cursor, a new layer is generated.
