.g., Strain et al ., 2006 ; Tolvanen and Kalliola, 2008 ), or those meeting specific academic needs ( Coetzee et al ., 2017 ; Da Dilva and Camboim, 2018 ). The first generation of SDIs in the 1970s were institutional or sectorial databanks, but with limited user focus. After the US National Spatial Data Infrastructure (NSDI) was established in the mid-1990s, SDIs started to support broader groups of users as well ( Masser 1999 ). In the early 2000s, this development initiated the second generation of SDIs, which aimed at more functional geoportal solutions ( Masó et al


In December 2014 in volume 60 issue 4 a paper was published entitled “A Framework for Evaluation of Marine Spatial Data Geoportals Using Case Studies” by Marina Tavra, Vlado Cetl and Tea Duplancic Leder which is suspected to constitute academic misconduct. This comment reasons that the core of the paper was taken from another source and thus does not offer new and original scientific work and therefore does not add knowledge to the body of science. Furthermore it argues that apart from the plagiarism the paper shows major weaknesses and thus should have not been published even it was not plagiarized.


The crowd-sourcing approach should be implemented into a new historical geoportal of Poland due to its increasing potential in WebGIS. Registered users will be able to acquire spatial data from various map series. As it requires feature class harmonization, a common symbol classification should be proposed. It will be based on chosen topographic maps of Polish land from the 19th and 20th centuries. Feature classes derived from archival maps will be standardized and reclassified, but with no information lost. This will be done in four steps which require: data acquisition, map content harmonization, feature class typification and attribute table elaboration. In addition, four methods of data harmonization can be distinguished: symbol sequence, semantic analogies, spatial relations and a combined method. The paper covers the elaboration of two thematic layers - roads and railways based on three topographic maps (Austrian 1:75 000, German 1:100 000, Russian 1: 126 000).

The issue of sustainable tourism within valuable natural areas has been extensively discussed ever since the emergence of sustainable development philosophy in the 1990s. In view of growing public interest in nature recreation and tourism development, the importance of addressing this subject matter has hitherto increased significantly. The main objective of the present paper was to offer a tool for supporting development and promotion of sustainable tourism in Poland’s forests managed by the State Forests - National Forest Holding. GIS technology, and specific tools for network analysis were used in the project. During task realization, only free and open software sources were used. The work was performed based on the example of the Forest District Żołędowo (Regional Directorate of State Forests in Toruń, Poland) with the use of District’s spatial data resources. A web application was created to present information about tourist attractions and infrastructure on an interactive map with tools for route planning. As a result, there has been developed the web mapping application which provides general access to tourism related information and enables planning touristic routes by pre-specified criteria. Implemented routing algorithms can help traffic management and further protection of the areas vulnerable to anthropogenic pressures. The system created not only promotes attractive tourist sites but also, supports targeting tourist traffic, and accordingly - adds to the progress of sustainable tourism
