ICTGI GIS Project Update

• Geodatabase• MnROAD Projection (Base Map)• Shapefiles

– Cell polygons – Sensor points (TC, WM, TB, VW, TD)– Distress Map points

» Crack maps (all scanned) » Reference stations

– Stationing

ICTGI TeamCurrent GIS Focus

1. Intelligent Compaction2. Building the Geodatabase

• ESRI or Oracle?• Interfacing with Oracle

– Oracle10g– Use SDE?– Use SQL connectivity to Oracle?– Geospatial Data Analysis

• Dealing with 3D and 4D data (MGS)

3. GPS and Mapping• Crack/Distress Reports

Distress Mapping: Past, Present, and Future

HAND DRAWN GPS

In the Past

• Cracks drawn by hand• Crack maps stored in

cabinets

• Crack maps were scanned to the R drive

Crack Maps in the GIS• Manually transfer the scanned

crack maps on to ArcMap• Manually Georeference map

with MnROAD base map• Hand Trace cracks onto

ArcMap• Hand enter crack features in

attributes table

Interesting GIS Facts

• 4159 hand drawn crack maps• 9043 cracks traced into ArcMap

FutureArcPad Features

• Variable zoom and pan.• Zoom to a specified layer or

spatial bookmark.• Center on the current GPS

position.• Measure distance, area, and

bearings on your map.• Identify features by tapping on

them.• Display additional information

about features through a hyperlink.
