Allows user to input a .csv of UTM coordinates within the Penobscot River basin and calculates in-river distance (in kilometers) from the river's mouth to the locations of interest. The results are output into a new .csv file named yourfilename+RKM.csv. For the purposes of this calculator, river kilometer 0 is located at 516414E 4927755N in UTM Zone 19N, near the southwest corner of Verona Island. Simply download the setup file and run it to install the program. Please contact me with suggestions to improve this program.

The Forestry Commission and Natural England commissioned a bespoke data collection and presentation tool for calculating the potential for increasing the extent of tree cover across the north west of England. The data was divided into sub-regions by landscape type using Natural England's Character Area classifications. The potential within each of these Character Areas was then estimated by working groups of local experts who were capable of making reasoned assessments of both the opportunities and constraints to woodland creation. Subsequently, this project was considerably extended and adopted as a national system. It is currently being used to compile the National Woodland Potential dataset for the whole of England.
