Outline
• The key features of SuperGIS Desktop v3.2,
combining with real case scenarios:
– Case 1: Generate Cache Map (Cache Generator)
– Case 2: Data Sharing in Spatial Database, based on OSM
– Case 3: View the GIS Data in PDF (Geospatial PDF)
– Case 4: Rectify on Image data (Georeferencing)
– Case 5: Precise Mapping (COGO, Advanced Editor)
– Case 6: Produce Map Atlas (Feature Guided Pages)

Case 01: Generate Cache Map
• Why we need to have Cache Map?
– Survey in the field by using mobile
solution
– Without internet connection
– How to ensure the location and start to
do the survey?

Case 02: Data Sharing in Spatial
Database • The headquarter of chain store wants to know
the distribution of each location on the map
• Every store has some basic information, ex:
address, phone number, total number of staffs,
contact info of manager,
even including the sales
revenue every year
