Resumen

[EN] Nowadays there is a trend in adding a map viewer to commercial websites. It is the best way of locating their own shops, or the place where you can find some product, and create a GPS track from your location. There are also more specific websites involved in showing cartographical objects (water, electrical, gas pipes, river, roads...) to their users. They can interact with these objects checking their length, if they are lines (pipes, roads, rivers) or areas (lakes, land parcels, buildings, pools...) and when they don´t need to look for the information in the databases, the website is programmed to prevent the users from doing this task. These map viewers are easy to create with commercial software. Geomatics engineers are taught the knowledge to create this, but with free software. Therefore, it is our duty to teach companies how to avoid these unnecessary payments and save money. The most used software in GIS world is ArcGIS, the GIS from ESRI company. This software has an expensive license and they require an annual payment. It is easy to install and has a friendly interface for creating and managing spatial objects like polylines, polygon or raster files. There are a lot of companies paying for it and sometimes it is not necessary to have this program. There are other free software programs (open source software) which can do the same functions as those provided by ESRI. That will be the basis of this project. One existing website, which is being developed by the students from Geomatics department of Hochschule Karlsruhe, shows cadastral information from four Slovakian villages. These data are composed of old cadastral, altitude, solar radiation, slope maps, agricultural, forest or settlement development, river and roads during more than 200 years. The website shows all this data with ESRI web map viewer and an open source software alternative will be found and programmed to be used instead of it. There is a lot of software to test, but the chosen one has to be able to run the same functions like ESRI website has The tests that will be performed will be about speed and features comparisons. Maybe the fastest alternative would be not the best choice if it doesn´t have all the functions used on the website with ESRI software. As concluding part, another test will be made for comparing the existing website version with ESRI software with the new version. It will be analysed beyond being a free alternative, also if the features and functions are working better or not.
