GDQM-PL13 – the new gravimetric quasigeoid model for Poland / Malgorzata Szelachowska in Geoinformation issues, vol 6 n° 1 (2014)  

Public [article]  inGeoinformation issues > vol 6 n° 1 (2014) . - pp 5 - 19 Titre : GDQM-PL13 – the new gravimetric quasigeoid model for Poland Type de document : Article/Communication Auteurs : Malgorzata Szelachowska, Auteur ; Jan Krynski, Auteur Année de publication : 2014 Article en page(s) : pp 5 - 19 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géodésie physique [Termes IGN] anomalie de pesanteur [Termes IGN] collocation par moindres carrés [Termes IGN] données GNSS [Termes IGN] géoïde gravimétrique [Termes IGN] Pologne [Termes IGN] quasi-géoïde Résumé : (auteur) 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 / Michal Kruczyk in Geoinformation issues, vol 6 n° 1 (2014)  

Public [article]  inGeoinformation issues > vol 6 n° 1 (2014) . - pp 21 - 35 Titre : Integrated Precipitable Water from GNSS as a climate parameter Type de document : Article/Communication Auteurs : Michal Kruczyk, Auteur Année de publication : 2014 Article en page(s) : pp 21 - 35 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications de géodésie spatiale [Termes IGN] données GNSS [Termes IGN] données météorologiques [Termes IGN] pluie [Termes IGN] retard troposphérique [Termes IGN] retard troposphérique zénithal [Termes IGN] série temporelle [Termes IGN] teneur en vapeur d'eau Résumé : (auteur) 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 / Beata Konopska in Geoinformation issues, vol 6 n° 1 (2014)  

Public [article]  inGeoinformation issues > vol 6 n° 1 (2014) . - pp 37 - 48 Titre : Using in-depth group interviews to optimize the design and communication of city maps produced for the public Type de document : Article/Communication Auteurs : Beata Konopska, Auteur Année de publication : 2014 Article en page(s) : pp 37 - 48 Langues : Anglais (eng) Descripteur : [Termes IGN] cartographie urbaine [Termes IGN] communication cartographique [Termes IGN] édition cartographique [Termes IGN] entretien d'enquête [Vedettes matières IGN] Cartologie Résumé : (auteur) 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.
