• Problems
• Mainroad Labels overcrowded
• Province Labels disappeared
• Solution
• Use MAXSCALE to control LABEL
• To know SCALE ? use TEMPLATE to show scale in
  modebrowse

29
Add TEMPLATE in MAP file (p06.map) .. WEB
IMAGEPATH "/ms4/tmp/" IMAGEURL "/tmp/"
TEMPLATE "p06-templ.html" END ..

• Make change in p07.map
• LAYER province
• STATUS on
• LAYER mainroad
• STATUS on

43

44

• LEGEND NOT DISPLAYED
• Solution
• Add NAME to each CLASS in LAYER

45

• Add REFERENCE MAP
• Hint
• Write p08.map
• Create a Reference map half size 300x200 using
  shp2img
• Must be .GIF
• Must have SAME Extent
• STATUS on

46
Add REFERENCE MAP Solution cd /ms4/map cp
p01.map ref.map nano ref.map ? Change SIZE
