• Introduction 

These are the common properties of the layers, and its controls are located in the top-right part of the panel.

From top to bottom and left to right, the properties are: 

• Name: The unique identifier name of the layer. There cannot be 2 layers with the same name. This control only is enabled during the process of creating a new layer. Note that only numbers, letters, and the underscore character ‘_’ are valid characters for a name. Invalid characters will be removed from the resultant name. Name cannot be left empty.
•  Alias: This is the visible name of the layer at runtime. Unlike the name property, alias property can be duplicated and most characters are allowed. If Alias is left empty, it will automatically take the same value as Name property. 
• ArchestrA Area: This is the name of an existing Area in the ArchestrA Galaxy associated to the layer. It is used by the integration update wizard process to know from witch Area the layer must be updated. 
•  WMS Name: List of Web Map Service layers associated to the GISIZE GEOSpatial layer. It’s used for custom online map providers that contain the parameter {6} in the URL definition. 
• Map Provider: A Map Provider can be linked to a Layer to superimpose it the current Map Provider when the layer is enabled. 
• Layer Icon: This control allows associating a small image to the layer. The image will be shown at the Layers Tab at runtime. Clicking in the control will open an explorer window to select an image. If the layer has a previously associated image, it will be shown inside the control. 
• Visible / Hidden: These buttons define the visibility of the layer. A hidden layer will never be shown. The main purpose of this functionality is to hide a layer temporarily, either because it is in development or because it will be used in the future.
• Panel Visible / Panel Hidden: These buttons define the visibility of the layer in the Layers Pane Selector at Runtime. However, its operation will be the same as the other layers, that is, they can be enable/disable by scripting and it will be enabled/disabled when enabling/disabling their parents in the selection panel.
• Min. Zoom: The minimum zoom which the layer will be visible. At lower zooms the layer will not be visible. Default value is 0 meaning there is no minimum zoom.
• Max. Zoom: The maximum zoom which the layer will be visible. At higher zooms the layer will not be visible. Default value is 999 meaning there is no maximum zoom. 
• ZOrder: Indicates the order in which the layers are stacked. It affects the visibility of the markers and shapes of the layers. The items of a layer with lower ZOrder will be displayed over the items of a layer with higher ZOrder.
• Panel Order: Indicates the order in the Layers Pane Selector at Runtime. 
• Marker Size: This control is a table located in bottom-left of the panel. The purpose of this table is to define the relative size of the markers that belong to the layer depending on the displayed zoom. To activate the dynamic resizing of markers in a layer, the checkbox labeled Enable dynamic markers size must be checked. 
• Shape Border Size: This control is a table located at bottom-center of the panel. The purpose of this table is to define the relative thickness of the shape borders that belong to the layer depending on the displayed zoom. To activate the dynamic resizing of shape borders in a layer, the checkbox labeled Enable dynamic shape border size must be checked.
• Parent Layer: Located in the bottom-right side of the panel, there is a tree view that contains all the current defined layers. Each node of the tree (except the very top one) represents a layer.  This control allows indicating which layer is the parent layer of the layer currently being edited.
