Dynamic Layers and dynamic Data
Harish Butani
via web
-
Is there a way to add custom layers. Something like the following OpenLayers snippet:
var vectorLayer = new OpenLayers.Layer.Vector("Overlay");
var feature = new OpenLayers.Feature.Vector(
new OpenLayers.Geometry.Point(-71, 42), {some:'data'}, {externalGraphic: 'img/marker.png', graphicHeight: 21, graphicWidth: 16}); vectorLayer.addFeatures(feature);
map.addLayer(vectorLayer); -
A followup question is: is it possible to setup dynamic Dataset with a GeometryTable/AttributeTable. Possibly using a GeoJSON string. We are wondering if it is possible to combine our Application data with the available datasets and using the combined data in a Map.

Click here for an example of adding a Mapfluence layer to OpenLayers
Please clarify: Are you asking if it possible to load your own data to the Mapfluence server and then render map tile layers based on that data you just loaded?
Thanks.

Yes we are looking at scenario 2. Based on our User's interaction and profile we would like to dynamically render a Map: would like both content and styling to be dynamic.
Is it possible to join Attributes from different Tables to come up with calculated values? An extension to this is to pass an inline Table in a Query ( I am equating this to SQL; I think all this is possible in PostGIS). We are wondering if you allow this through the Api.
regards,
Harish.

To calculate new values to map you can use expressions in the ``select``
property of a map layer.
Guide here:

Reference doc here:

Styling of the image tiles of map can also be customized by changing
properties of a Mapfluence layer object such as border, styles, opacity
and zoom. (example documentation:
http://developer.urbanmapping.com/docs/mapfluence/js/2.0/reference/MF/layer
/tile/Thematic)
Here is a complete list of maps that can be made:
