• Concept Of Terrain Layers– Maximum Of 1023 Layers– Maximum Grid Size Per Layer

• 2047 By 2047

• Grids Can Be Of Following Sizes– Degrees: 10, 5, 1– Minutes: 30, 15, 5, 1– Seconds: 30, 15

• Every Scenario Starts With– World_Level Layer

• 10 Degree Grids Covering Entire World• Results In Grid Layer 36 by 18

– Build Layers On Top Of That Layer• Terrain Layer Name, Number X Grids, Number Y

Grids, Layer On Which It Is Build, Anchor Grid

• JTLS 4.1 Hexes Automatically Converted

• Comparison Of Terrain Data demsdbkor– demsdbkor41 Hexes: 263,652– demsdbkor50 Converted Grids: 274,229– demsdbkor50 Created Grids: 32,785

• Probably needs more• Some shoreline areas need more detail

• Fake Terrain– Shape Files Place On

• Local Machine (Just Like CADRG)• In Directory

– $JHOME/ShapeFiles– C:ShapeFiles

• Significant Pre-Processing– National Boundary Tags

• Grids And Network Arcs

– Barrier Tags• Suggestion

– Start The Game– Run Ahead A Few Seconds– Take A Checkpoint– Restart From Checkpoint 1
