This paper upgrades the ERKć2009 paper and describes an analysis of collected field data and improvements made to the acquisition system to minimize possible errors. A short recapitulation of the ...previous-year paper makes our data collection system comprehensible. Collected field are analysed and all possible errors are divided into three groups. The main errors, that are also the most common ones, are errors caused by mistakes in manual selection of plantation. Geometrical data for those plantations, publicly released by the Slovenian government, help reduce the most common mistakes, but our mobile application had to be upgraded first. As the boundaries of all plantations areknown, we were able to found out whether the userćs current GPS position isinside a specified polygon or not, and to which polygon this position belongs. This decision can be computed by a simple point-in-polygon test.
