Project Objectives:
The purpose of this project is to obtain and process high-resolution
satellite imagery for a test site or sites in the L.A. Port to demonstrate
image classification, change detection and feature extraction for development
and rapid updating of a Geographic Information Systems (GIS). The data acquired,
processed and presented through this project will provide a foundation that
will directly contribute to an understanding of goods movement and trade transportation
problems confronted by metropolitan areas.
This proposal will investigate and document techniques to classify data and
extract information from satellite imagery and airborne light detection and
ranging (LiDAR) data and import the extracted information into a GIS. Automation
of the best techniques(s) will also be demonstrated. Assessment of the accuracy
as well as the time and cost savings (where possible) will also be conducted.
These projects are intended to provide a “proof of concept” that
can be applied to a larger project to create a METRANS GIS of the Los Angeles/Long
Beach Port complex.
Tasks:
A. Four quarterly progress reports.
B. One final report.
C. Demonstration data layers of manmade features extracted from the satellite
imagery and improved by integration with the LiDAR data Target
layers include: buildings, other structures, vegetation, streets and highways.
D. Documentation of methods and procedures used to process, classify, update
and extract features will be provided in the appropriate quarterly report(s).
E. 3D fly-through visualization for the selected study area to demonstrate
the functionality of the data for current and future port-related applications
and analyses.
