If the data source is an ESRI/Shape (.shp) file, there are additional options that you can use.
The following figure shows both the Advanced and Select Projection options selected.
Select data sources pane for ESRI/Shape file
Choose File>Add Map Data to display the Select Data Sources pane.
Select Use Tiling, if you want to have an additional index file (.idx) managing the shape file using a load on demand algorithm. If the
index file does not exist, the Create index file pane asks you if
you want to create a new one.
To create a new index file, click Yes to display the
Tiling parameters pane and enter the parameters you want.
The following figure shows the Tiling parameters pane.
If your shape file has an associated dbf (database) file
and thus contains metadata, you can use this to filter so that you
load only a subset of the file content. To do this, select the Filter tab, select the Activate
Filter check box and define your filter by selecting
items from the drop-down lists.
The following figure shows the definition of a filter
which will only load San Francisco streets which have ZIP codes greater than “92000”.
