Layer - Map

In This Topic

Following is a description of the layer map settings:

Visible - controls the visibility of the map layer.

Map

Map Type - defines the type of map displayed by the map layer. Possible values are: Predefined Map and ESRI Map.

Predefined Map - when the Map Type is set to Predefined Map, this combo box lets you select amongst the currently available predefined maps. Nevron Map for SharePoint comes equipped with predefined maps for the World, USA and all USA states.

Load ESRI Shape File... and Load ESRI Dbf File... buttons - this pair of buttons is visible only when the Map Type is set to ESRI Map. It lets you specify the shape file and map data file associated with the map in ESRI format.

Each ESRI map consists of two files:
- .shp file - also called shape file. Contains geospatial data for the map.
- .dbf file - also called map data file. Contains tabular data about each shape in the shape file.

Preview Dbf Data - for the currently defined map, this button lets you preview the content of the associated map data table (if any).

Fields

Value Field Name - a combo box which lets you select a column from the joint table that must be used as value for the geographical shapes contained in the map. This value is used by the Layer - Fill Rule to determine the filling of the shape. It can also be displayed in the legend (see Layer - Legend).

Text Field Name - a combo box which lets you select a column from the joint table that must be used as text for the geographical shapes contained in the map. This value can be displayed in the legend.

Settings

ShowTexts - controls whether texts are displayed over shapes.

Polygon Labeling Mode - for polygon layers, controls the position of the text relative to the shape. Possible values are:

Bounds Center - the text is placed in the center of the shape bounds (fastest)
Centroid - the text is placed in the polygon centroid.
Optimal - the text is placed in the largest polygon area (slowest but with best quality).

Hide Shapes Without Data - because of the nature of the Left Outer join that is performed between the map data and the layer data table, not all records from the map data may have corresponding records in the layer data table. You can check this check to "hide" such shapes from the map.
