The filtering of binary images containing graphic and text information possesses typical peculiarities and uses heuristic processing procedures. At the same time the application of grey level methods for processing of digital images gives a lot of advantages. It is introduced an approach for the processing of binary images that is based on the adaptation of algorithms for grey level images like boundary detection, contour tracing, and line tinning. It is made the comparison of methods for binary filtering and corr...

A review of the CAD systems used in the investigation planning, possibilities to automate planning and the basic directions related with planning are done. Examples for achieved results when developing software for the specialized investigation activities and when working with the program package “Geodesy” are given.

The technical specifications defined from instrumentation owners of suitable for remote access expensive equipment in Earth Sciences domain are presented. The database containing all mentioned above structured information is created and used as analytical tool in this investigation. The user community requirements in several different domains for application of remote access are evaluated and analysed. This work is one of the main parts of RINGrid project (Remote Instrumentation in Next-generation Grids) under the...

In this paper some specific problems concerning the database and information quality are presented analyzed. There are emphasized some approaches presented in the literature and some “classical” mistakes encountered in practice.

This paper has been accomplished in the framework of Diminish Project (LIFE03 ENV/ RO/000539) within the Life Environment Program. In accord with the Water Framework Directive the nutrient management is a decisive factor for increase the water quality. In this respect the Diminish on-line system, based on GIS database and modeling approach and using Open-GIS technology, allows diminishing uncertainties related to basin management. The Bistrita River (283 km length, 7039 km2) had proven to be specifically sensitive...

This case study presented herein compares the landslide susceptibility mapping methods of frequency ratio (FR), logistic regression and artificial neural networks (ANN) applied in the Kat county (Tokat-Turkey). Digital Elevation Model (DEM) was first constructed using a GIS software. Parameter maps affecting the slope stability such as; geology, faults, drainage system, topographical elevation, slope angle, slope aspect, topographic wetness index (TWI) and stream power index (SPI) were then produced from DEM of th...
