Search field

4. Search field
The user can add a search field if he/she wants to use this layer as a searchable layer to navigate with or run spatial reports from it.
 
Please note:  Only use this tool with layers with unique values per entity!!
Not all layers or their attributes is to be regarded as searchable.  An example of a good searchable layer is Towns.  Each town is represented by a single point entity and once it is selected in the search box,  it will zoom to that specific  entity.  An example of layer that is not regarded as searchable is Geology.  There are many polygons in the set with the same attribute.  One cannot search and zoom to more that one polygon at once.  Thus same layer will be unsuitable and unlogical to be used with this function.

Legend

7. Legend
The Legend is normally automatically generated for all vector images. In the case of graphics and layers derived from WMS services, a legend file can be uploaded to the server.  This will always have to be in PNG graphic format.  The suggested size is 270x270 pixels.

Opacity

8. Opacity
The Opacity for the layer can be set at two places in MapAble.  This opacity tool in  the Main Layer Input Box can be used to set the global opacity of the layer.  Some individual items can be set in the Thematic visualisation toolbox.
 
The opacity is measured in an index of 0 - 255 of which 0 = none opacity (fully transparent) and 255 = full

Drawing Order

9. Drawing Order
The Drawing Order refers to the way MapAble renders polygons and polylines.  The Drawing Order is important in the construction of maps where the user wants certain layers to be displayed above others such as place names above certain polygons. A layer can either be positioned the top or bottom most or normal which means the layer order in the layer list.
