Centre for Geo Information3
Spatial Application Componentsa) Spatial & Tabular data preparation (Pre-
processing).b) Automatic computation of the most desirable
light rail route and corridor.c) Interactive user (re)design of the Light Rail d) Fulfilling project criterion (reach light rail
within 5 to 10 minutes walk)e) Calculation of the approximate costs of the Light
Railf) Map presentation for stakeholders
Centre for Geo Information4
Light rail route and corridor.
Light Rail Route Light Rail Corridor
Centre for Geo Information5
Component c: Interactive user (re)design
• Automatic generated path and corridor• Based on land use as main criteria for
suitability factors.• User determined criteria (political, usability,
etc.)
• Included in (re)design
Centre for Geo Information6
User (re)design
70% of the population must live in a walking distance of 5-10 minutes
Centre for Geo Information7
Examples of where user decisions must be made
Wageningen
Bennekom

Handy Background Layers during (re)design Route
• Weight factors determining the corridor • Light Rail Corridor: degrees of freedom
more in non-buildup areas• Computed Light Rail Route
Centre for Geo Information9
(Re)Design Route
• Data exploration in ArcCatalog• Data viewing ArcCatalog (single datasets) /
ArcMap (Multiple datasets)
• Editing– ArcCatalog (Creation of new empty
datasets)– ArcMap (Filling datasets by digitizing)

Digitizing1. Create new datasets in ArcCatalog
• Adding a map coordinate system and user-defined attributes to a geo-dataset
2. Preparing the digitising environment in ArcMap
3. Adding data to a spatial dataset in ArcMap (Digitizing)
Centre for Geo Information1
1
Map coordinate systems
• Principle in ArcGIS– Each dataset must have a coordinate
system defined
• Dutch National grid– “Rijksdriehoekstelsel New”
• Reference data for digitizing (background layers)

Presentation reference dataDatasets concerning
• Weight factors• Light Rail Corridor• Light Rail Route• Infrastructure• Etc.
