You should load the gds in EDI., the LEF does not have enough information.

I think you can't load GDS in EDI. Encounter supports only LEF. You have to use calibre RVE for viewing GDS.

Right Encounter could not read directly the layout, but you could create an Open Access data based and read it in EDI.
To create the OA library from LEF and GDS, use the following commands:
lef2oa -lib testLib -lef lefFile -libPath ./testLib -DMSystem oaDMFileSys
strm2oa -lib testLib -gds gdsFile -layerMap layer.map

Specify the following global prior to running init_design:
set init_oa_ref_lib {testLib}
set init_layout_view {layout}
set init_abstract_view {abstract}

After the design is imported you can display the layout of a cell by doing the following:

Expand "Cell" in the Layer Selection Window on the right side of the EDI System GUI.
Select the Visibility box next "Cell Layout".

To edit colors and patterns of the layout objects select the "All Colors" button in the upper right. Then select the Cell Layout tab to see the OA layers.
In EDI 10.1 and earlier versions specify the following in the config file to specify the OA library and views to load:
set rda_Input(ui_oa_reflib) {testLib}
set rda_Input(ui_oa_abstractname) {abstract}
set rda_Input(ui_oa_layoutname) {layout}
