Van der Schaaf, H.P. (author)
In the past ten years there has been a growing tendency to use hyperbolic, circular and 'are of circle patterns for position fixing on water-covered areas. Rijkswaterstaat Communications No. 2 discusses the computations associated with the Decca pattern for the Netherlands Delta Project as one ofthe first examples ofthe use of electronic...

The spectral distribution of radiation reflected by crops in the visible light region and the near infrared contains information concerning crop structure and the optical properties of the leaves and the bounding soil. Non-destructive determination on remote distance of crop properties by means of the measured spectral distribution of reflected...

A uniform, effective and equitable system of quality control for pavements has been applied to road-building projects in the Netherlands since 1968.The system has been developed in consultation between the public authorities and the con tractors' organizations. The system is characterized by a distinction between regular, daily production...

Image quality plays an important role on the various levels of image processing. However, until now it lacks a survey of methods for the evaluation of image quality. With a grant of the Netherlands Agency for Aerospace Programs (NIVR) a study was performed with respect to the quantification of image quality. Some results of this study are...

A simple analytical four-stream radiative transfer model based on Suits's differential equations is applied to the atmosphere-earth system in order to investigate the effects of the atmosphere and the view angle on remotely sensed multispectral radiance data from vegetation canopies. This scene radiation model is composed of two atmospheric...

The image segmentation algorithm has been tested by means of imagery of agricultural areas and forests acquired by airborne SLAR as well as Seasat SAR. The accuracy was determined for segmentation without any postprocessing and with emphasis on estimation of area and field average. Besides, the (positive) influence of segmentation on...

Microwaves (i.e. X-band SLAR) have been used in The Netherlands for many years within ROVE to identify agricultural crops. This report deals with data acquisition, preprocessing and classification of agricultural crops in The Netherlands using the Dutch Digital SLAR. With internal and external calibration of the instrument satisfactory results...

The National Aerospace Laboratory "NLR" is the operator of an aircraft which can be equipped with either a SLAK, a multl spectral scanner or a TVbased scanner. The airborne recording equipment la designed to accommodate these various sensors. The general airborne system setup is: the sensor, a dedicated digitizing unit and an Interface to a High...

Within the framework of the National Remote Sensing Programme and under contract with the Netherlands Remote Sensing Board (BCRS), the National Aerospace Laboratory NLR has carried out a Phase-A/B study of a national ERS-1 data and information centre. The first European Remote Sensing Satellite (ERS-1) is due to be launched by the European Space...

Project CADISS has produced an elegant breadboard of a system for compression (and -if required- decompression) of signals generated by imaging sensors on-board scientific satellites. The performance, specifications and physical characteristics of CADISS are the result of trade-offs on function (algorithms), technology, through-put speed and...

Verhoef, W. (author)
In the past, a relatively simple radiative transfer model, based on scattering and extinction of two semi-isotropic diffuse fluxes and two direct fluxes (solar beam and radiance in the viewing direction), has been applied to vegetation canopies and to the atmosphere. This model takes little computing power, but its numerical accuracy had not yet...

This paper examines the possibilities of using Landsat Thematic Mapper images for updating land-use information on topographic maps. Information obtained from satellite images can be kept up-todate and a large number of classes can be distinguished. However, the quality of the information still leaves much to be desired, with a reliability of no...

Within the framework of the National Remote Sensing Programme, an airborne push-broom scanner was developed in The Netherlands by the National Aerospace Laboratory NLR and the Institute for Applied Physics TNO-TH (TPD). With the development of this scanner, named CAESAR, two objectives were fulfilled: technical knowledge about CCD detectors and...

Working with Remote Sensing data can be generalized into four categories: - registration - processing - interpretation - presentation. A short overview of these four categories will be given. Emphasis will be put on the Dutch airborne multichannel pushbroom scanner CAESAR showing specific geodetic points of interest in working with Remote...

This paper describes aspects of system design applied to the ARTEMIS environmental monitoring system of the Food and Agriculture Organization (FAO) of the United Nations. The design aspects are derived from characteristics of the monitoring function and are based on methods of rainfall and vegetation monitoring from satellite observations which...
