GDQM-PL13 – the new gravimetric quasigeoid model for Poland
DOI: 10.34867/gi.2014.1
Abstract. The new gravimetric quasigeoid model GDQM-PL13 for Poland was determined. The 1’×1’ mean Faye anomalies, deflections of the vertical for the territory of Poland, gravity anomalies from the neighbouring countries and the EGM2008 were used as input data. The remove-compute-restore (RCR) method and the least squares collocation approach with the planar logarithmic covariance function of gravity anomalies were applied. Height anomalies computed from the GDQM-PL13 have been compared with the corresponding ones obtained from GNSS/levelling data at the stations of the POLREF, EUVN and ASG-EUPOS networks and the precise GNSS/levelling control traverse. The new quasigeoid model was also compared with the gravimetric quasigeoid model GDQ08 developed in 2008 for the area of Poland, with the EGM2008, and with the most recent global geopotential model based on GOCE data. The results of the comparison were analysed and the accuracy of the GDQM-PL13 has been assessed and discussed.

Integrated Precipitable Water from GNSS as a climate parameter
DOI: 10.34867/gi.2014.2
Abstract. Tropospheric delay estimates (tropospheric product) on selected International GNSS Service (IGS) and EUREF Permanent Network (EPN) stations exhibit large information potential for meteorology and climate research. Long time series of integrated precipitable water (IPW) averaged hourly, daily and monthly can serve as climate indicators. As IPW is mostly influenced by global circulation, not surface processes, correlations of IPW with basic meteorological surface parameters have been analysed. Even more revealing are changes in correlation coefficients calculated for monthly periods for different regions.
Simple charts of IPW/temperature which can be treated as climatologic diagrams were investigated. Some of these charts have been analysed with some climatologic insight. This form of presenting IPW statistics reveals the variability of seasonal IPW values. IPW clearly represents the diversity of world climates and is a valuable meteorological and climatologic parameter.

Using in-depth group interviews to optimize the design and communication of city maps produced for the public
DOI: 10.34867/gi.2014.3
Abstract. The paper presents a study of city maps using the in-depth group interview method and discusses the use of the results obtained in optimizing the effectiveness of cartographic communication. This study indicated the content of city maps and their graphic form preferred by their users, and showed the extent to which educational gaps in map-reading skills lead to losses in cartographic communication. The results of the study were used to develop editorial and technical principles regarding city maps offered under the brand name of Copernicus by the E. Romer Polish Enterprise of Cartographical Publishing Houses S.A [Polskie Przedsiębiorstwo Wydawnictw Kartograficznych im. E. Romera S.A.].

CORINE Land Cover 2012– 4th CLC inventory completed in Poland
DOI: 10.34867/gi.2014.4
Abstract. The first European and Polish CORINE Land Cover map was created for the reference year 1990, then subsequently for 2000 and 2006. The long heritage of CLC inventories allows researchers to perform a long-term analysis of land cover dynamics at national and European scale. This article focuses on the results of the CLC2012 inventory and analysis of land cover changes which occurred between 2006 and 2012. The 4th CORINE Land Cover inventory was carried out by the Institute of Geodesy and Cartography (IGiK). After an effort of one and a half year of mapping using visual satellite image interpretation, the CORINE Land Cover 2012 and land cover changes 2006-2012 for the entire country have been completed. The total area of land cover changes between 2006 and 2012 reached about 1% of the territory of Poland (309 741 ha). More than 75% of land cover changes occurred in forest and semi-natural class, almost 19% in the artificial class, 5% in agriculture land and the remaining 1% in wetlands and water bodies.
