چکیده
NOTICE This Technical Report does not necessarily represent final EPA decisions or positions. It is intended to present technical analysis of issues using data that are currently available. The purpose in the release of such reports is to facilitate an exchange of technical information and to inform the public of technical developments. 1. Introduction This document is intended to provide guidance for performing I/M program evaluations using a Remote Sensing Device (RSD). The next section is a background regarding EPA regulation of state I/M programs and a history of methods used to evaluate these programs. Section 3 describes different approaches to evaluate I/M programs, using roadside pullover data or independent remote sensing measurements. Section 4 summarizes equipment specifications and measurement procedures, while Section 5 outlines important design parameters for the collection and analysis of RSD program evaluation data. Section 5 also discusses quality control issues that should be considered in an evaluation. Section 6 describes in detail three alternative methods to perform short-term evaluations of the I/M programs using remote sensing data and discusses the advantages and disadvantages of each. The three methods are the Step Change, the Comprehensive, and the Reference analysis methods. How in-program data can be used to evaluate the long-term, cumulative effect of I/M programs is covered in a separate document. Appendix A contains some simple trouble-shooting methods that can be applied in the field as a first check to determine if an RSD unit is functioning properly.

متن کاملPerformance Evaluation of Local Detectors in the Presence of Noise for Multi-Sensor Remote Sensing Image Matching
Automatic, efficient, accurate, and stable image matching is one of the most critical issues in remote sensing, photogrammetry, and machine vision. In recent decades, various algorithms have been proposed based on the feature-based framework, which concentrates on detecting and describing local features. Understanding the characteristics of different matching algorithms in various applications ...
متن کاملRemote sensing for urban heat and cool islands evaluation in semi-arid areas
Cities are experiencing rapid population growth and consequently extensive urbanization. Land-use/land-cover change is one of the important elements worldwide, which significantly affect the environment. This study aims to describe the emergence of urban heat and cool islands as a result of changes in land-use/land-cover. Land surface temperature over a 32-year period in Isfahan city, Iran was ...
