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...report 1972

Bunnik, N.J.J. (author)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...report 1977

Brunsveld van Hulten, H.W. (author)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...report 1984

van der Lubbe, J.C.A. (author)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...report 1984

Verhoef, W. (author)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...report 1985

Nooren, G.J.L. (author), Hoekman, D.H. (author)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...report 1986

Uenk, D. (author), Binnenkade, P. (author)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...report 1986

Pouwels, H. (author), Aartman, L.J. (author)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...report 1986

Roefs, H.F.A. (author), Monkel, A. (author)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...report 1987

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...report 1988

van der Laan, F.B. (author), Meijer, P.G. (author)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...report 1988
