Lesson 2
Adding Alleys

Alleys from an alley only map are automatically transferred and connected to a street map.

Lesson 3
Aligning Polygons

MapMerger precisely aligns features in two overlapping maps by ensuring that matching features share the same geometry.

Lesson 4
Synchronizing Data Updates

An original Navteq map that has been edited is synchronized with a new Navteq update.

Lesson 5
Rapid Change
Detection

An original and updated road map are compared and the roads with differing attribute values are automatically identified and symbolized.

Lesson 6 – Part 1
Matching Maps at Different Scales

Techniques are demonstrated for manually matching difficult match scenarios involving streets depicted at different scales.

Lesson 6 – Part 2
Matching Maps at Different Scales

Techniques are demonstrated for manually matching difficult match scenarios involving streets depicted at different scales.

Lesson 7
Match
Strategy Layer

A Match Strategy Layer is used to match a street dataset containing urban and rural regions that have diverse match characteristics.

Lesson 8
Merge
Parameter Layer

The lesson will show how different regions can switch source and target, change direction of attribute transfer and change whether an area is densified or aligned.
