Abstract

Primary Signed Route locations. The dataset contains locations and attributes of Primary Signed Routes, created as part of the District of Columbia, Department of Transportation (DDOT) Street Spatial Database (SSD).

A database provided by the District of Columbia, Department of Transportation identified StreetSegment locations.

All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.

METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.

Purpose

This data is used for the planning and management of Primary Signed routes Events - Assets, Activities, Incidents, as well as the maintenance of Reference Features of the District of Columbia, Department of Transportation (DDOT).

Lineage / Sources

Lineage / Processes

in Earth Data Corporation


 , ,

The District was flown over to capture aerial imagery at < 1 meter resolution. These aerial images were orthorectified.

in Earth Data Corporation



The aerial photos were vectorized to extract linear featutes such as street, alley and driveway centerlines and produce the planimetric maps of the City

in Dewberry and Davies



To create attributes for the vectors each geometry was linked to corresponding street segment records from the existing Street Inventory System (SIS).

in Dewberry and Davies / Michael Baker Corp



The planimetric data derived from the aerial photos and the attribute data extracted from the Street Inventory System (SIS) were subjected to quality checks and field verification.

This process step was carried out to correct the direction of flow on street segments. This was done programmatically by the Senior GIS Analyst
