Efficiency of artificial neural networks in map of total electron content over Iran

Maps of the total electron content (TEC) of the ionosphere can be reconstructed using data extracted from global positioning system (GPS) signals. For historic and other sparse data sets, the reconstruction of TEC images is often performed using multivariate interpolation techniques. In this paper, a quantitative comparison of the ability of artificial neural networks (ANN), ...

Preface

Publishing globes on the internet

This paper presents possible solutions to the problem of interactive digital globe publishing on the Internet in connection with the recently opened Virtual Globes Museum. It describes the processing method of two possible source materials: globe prints and photographs. The visualization of the results is realized in two different ways. The first one is a 3D virtual world created ...

Mosaicking of the 1:75 000 sheets of the Third Military Survey of the Habsburg Empire

The original map sheets of the Third Military Survey of the Austro-Hungarian Monarchy cannot be mosaicked in their original, printed form because of their uneven trapezoid format. To make a digitized raster mosaic of the individual sheets, they all should be georeferenced. Instead of the original projections, which vary from sheet to sheet, a series of sinusoid projections was ...

Hungarian national report on IAG 2007–2010

In sum, the following activities were done: a) the IAG website was updated, improved and continuously maintained b) the IAG Newsletter was regularly issued monthly and distributed electronically, and selected parts of them were prepared to publish in the Journal of Geodesy as IAG News c) new version of the IAG Leaflet was prepared, printed and distributed at different IAG meetings ...

Rediscovering the old treasures of cartography — What an almost 500-year-old map can tell to a geoscientist

Tabula Hungariae (1528), created by Lazarus (Secretarius), is an almost 500 year-old map depicting the whole Pannonian Basin. It has been used for several geographic and regional science studies because of its highly valued information context. From geoscientific point of view this information can also be evaluated. In this contribution an attempt is made to analyse in some extent ...

Cartometric analysis of the Czechoslovak version of 1:75 000 scale sheets of the Third Military Survey (1918–1956)

The 1:75 000 scale Special Map (SM75) series of the Third Military Survey is analysed in this work. Geographic co-ordinates of the sheet corners are computed from the sheet number codes, as well as their grid co-ordinates in the modern Křovák Projection and Czech and Slovak national grid called S-JTSK. Distortions caused by paper drying and shrinkage were analysed and a ...

Horizontal control for stable cadastre and Second Military Survey (Franziszeische Landesaufnahme) in Bohemia, Moravia And Silesia

The paper deals about significant projects of large scale mapping at the beginning of 19th century in the Habsburg Empire. They have been already based on uniform geodetic horizontal control. Basic parameters and features of Second Military Survey in the territory of the Czech Lands as well as links with project of Stable cadastre are delineated. Technology of establishing the ...

Georeferencing the first bathymetric maps of Lake Balaton, Hungary

Lake Balaton is located in the Pannonian Basin, Hungary (46°50′ N, 17°50′ E), and is characterized by its large area (594 km2) and very shallow water depth (avg. 3.5 meters). The main tributary is the Zala River, which enters the western bay, and the only outlet is the Sió River in the East. Sámuel Krieger conducted the first known survey focusing on Lake Balaton in 1776. The ...
