Straight Line Diagrammer

Description:

The straight-line diagrammer (SLD) project was focused on creating a simple tool that would create PDF diagrams showing the changes in various attributes along a section of road.

This web application presents an easy to use interface, allowing users to select the attributes of interest which are then displayed on the SLD.

The back-end service utilizes ArcGIS Server to create a location map and perform necessary geo-spatial operations. The Straight Line Diagram itself is generated on the fly from segment attribute data stored in Oracle. The open-source iTextSharp PDF library was used to generate the images. Low-level PDF primitives are manipulated to produce the diagrams, resulting in crisp, zoomable graphics.

The system went into production in the Spring of 2010.
