Sub-Sahara Afrika verstedelijkt in een snel tempo. Het grootste probleem is dat de landen niet de juiste instrumenten tot hun beschikking hebben om die stedelijke groei beheersbaar te laten plaatsvinden. Omdat het bestuur er niet in slaagt voldoende land uit te geven, zullen de burgers het land op informele wijze in bezit nemen waardoor ze later kwetsbaar blijken voor uitzetting en verlies van...

Satellietradarinterferometrie (InSAR) is een effectieve techniek om beweging van het aardoppervlak te meten. De toepasbaarheid van de conventionele aanpak is echter beperkt vanwege foutenbronnen: temporele decorrelatie, geometrische decorrelatie, en atmosferische signaalvertraging. Om deze verstorende factoren te ondervangen zijn radarinterferometrische tijdreeksmethoden ontwikkeld...

Regional gravity field modeling using airborne gravimetry data Airborne gravimetry is the most efficient technique to provide accurate high-resolution gravity data in regions that lack good data coverage and that are difficult to access otherwise. With current airborne gravimetry systems gravity can be obtained at a spatial resolution of 2 km with an accuracy of 1-2 mGal. It is therefore an ideal technique to complement ongoing satellite gravity missions and establish the basis for many applications of regional gravity field modeling. Gravity field determination using airborne gravity data can be divided in two major steps.

Safe nautical charts require a carefully designed bathymetric survey policy, especially in shallow sandy seas that potentially have dynamic sea floor patterns. Bathymetric resurveying at sea is a costly process with limited resources, though. A pattern on the sea floor known as tidal sand waves is clearly present in bathymetric surveys, endangering navigation in the Southern North Sea because of the potential dynamics of this pattern. An important factor in an efficient resurvey policy is the type and size of...

The gravitational field of the Earth is caused by the heterogeneous mass distribution of the Earth. Due to this field, the mean sea level (at rest) shows fluctuations (geoid heights) up to 100 meters with respect to a reference ellipsoid. The time-varying gravity signal is a source of information on the melting of the polar ice, the hydrological cycle and other mass variations within the Earth. Moreover, the gravity field of the Earth is needed to derive the physical (orthometric) heights and to estimate the ocean at rest, which is necessary for...

This dissertation presents a new topological approach to data modelling, based on a tetrahedral network. Operators and definitions from the field of simplicial homology are used to define and handle this structure of tetrahedrons. Simplicial homology provides a solid mathematical foundation for the data structure and offers full control over orientation of simplexes and enables one to derive substantial parts of the TEN (TEtrahedronised irregular Networks) structure efficiently, instead of explicitly storing all primitives. DBMS characteristics as...

The storage and retrieval of spatial data in computer systems has matured greatly over recent years, from the earliest approaches (of simple digitised linework and text) to the representation of features and their attributes, with the semantics of their behaviour associated. This has led to massive cost savings where data, which might have been captured for a specific purpose, can be shared and reused for other purposes.

Data processing in geodetic applications often relies on the least-squares method, for which one needs a proper stochastic model of the observables. Such a realistic covariance matrix allows one first to obtain the best (minimum variance) linear unbiased estimator of the unknown parameters; second, to determine a realistic precision description of the unknowns; and, third, along with the distribution of the data, to correctly perform hypothesis testing and assess quality control measures such as reliability. In many practical applications the covariance matrix is only partly known. The covariance matrix is then usually written as an unknown linear combination of known cofactor matrices.

The growing availability of spatial data along with growing ease to use the spatial data (thanks to wide-scale adoption of GIS) have made it possible to use spatial data in applications inappropriate considering the quality of the data. As a result, concerns about spatial data quality have increased. To deal with these concerns, it is necessary to (1) formalise and standardise descriptions of spatial data quality and (2) to apply these descriptions in assessing the suitability (fitness for use) of spatial data, before using...

In the Netherlands, a precision of 5 mm for estimated GPS height differences is required to achieve comparable accuracy as geoid height differences. This precision can be achieved for 24-hour data sets when applying a proper modeling. Precise leveling with GPS requires a judicious modeling of tropospheric delays, which has physical, functional, and stochastic aspects. The physical modeling comprises zenith delays for..

A global model of the Earth’s gravity field may be derived from satellite observations such as satellite tracking observations or satellite gravity gradiometry (SGG). Due to the satellite’s altitude above the Earth’s surface, the gravity field recovery from satellite data is an ill-posed problem since it lacks stability. In addition, the spatial data distribution is heterogeneous in...

The problem of radial orbit errors in processing of satellite altimeter data is largely due to the inaccuracy of the gravity model which is required for the computation of the trajectory of the spacecraft. A commonly used technique for removing these errors consists of minimizing the crossover differences of profiles measured by the altimeter...

Multiple-station very long baseline interferometry (VLBI) is considered from a geodetic point of view. An approach is outlined to deal with relative phase delay data as obtained from measurements on both artificial radio sources at finite range and natural sources at infinity, observed in the simultaneous mode. The approach is basically a range-differences method and allows a treatment in theoretically convenient steps to...

Since 1957, when the standard base line 'Loenermark' was established by our Finnish colleagues Prof.Dr. T.J. Kukkamäki and Prof.Dr. T. Honkasalo, its length has served many times for the calibration of invar tapes used in primary geodetic measurements. The most important of these measurements were: remeasurement of the German base line near Meppen (1960) and measurement of the new 24 km - long triangulation base line 'Afsluitdijk' in...

The first part is a report taken from the doctorate thesis by Dr. J. van Boeckel (thesis Amsterdam, 1968). The author made a detailed gravity survey in northern Surinam in the years 1958 and 1960. He travelled thousands of miles, mostly by corjaal (= canoe), and made more than 400 gravity stations along the Surinam rivers. The gravity field of northern Surinam appears to be characterized by a belt of negative anomalies in the centre of the country, and by a region of positive deviations in the western part. The author gives an ...

The methods for testing circles applied up to now can be arranged in two groups. The first group consists of the methods which have the object to determine the deviations in a limited number of specified graduation lines, evenly spaced on the circle. Originally these methods were applied to circles before they were mounted, but recently modifications of the observational programmes have also been used to test circles already built-in.

In the present thesis a description is given of a new self-reducing range-finder by means of which both reduced and unreduced distances, height differences, and bearings can be measured. The thesis also deals with the way in which measuring data and the further data regarding the points to be measured are automatically registered on a magnetic tape. This is followed by the description of an electronic apparatus by means of which the data are transferred from the.

In this paper the starting point is formed by some elementary applications of statistical methods to geodetic adjustment problems. In its line of thought the paper is connected to earlier publications, such as [Baarda 1960, 62]. An indication is given of some difficulties of principle which are inherent in these applications, and which often make the value of tests illusory.This leads to...

The possibility of using vertical angle measurement as a means for determining deviations of the vertical has been investigated by several geodesists. In his papers [3], [4], [5] and [6], R. Finsterwalder did important pioneering work which was and is continued especially in Germany and Switzerland. F. Kobold gave in [10] a survey of the results that have been reached in this field, whereas W. Hofmann in his comprehensive study [8] investigated the possibilities of determining accurate geoidal heights and deviations of the vertical by vertical angle measurements.
