* The element G_23 of the Jacobian matrix of linearized observations in formula 18 (page 4) in this paper has an incorrect sign (minus sign should be removed). This is discussed in: https://doi.org/10.1007/s10291-025-01932-7.
This project helps to digitize field data for a certain Bird Census method.
Namely, bird census based on personal inspection or small (~10 km^2) regions with recording birds' position and behaviour on paper.
This project makes it easy to annotate such field data and to make this data available for statistical analysis.
...Thus a patchwork is made to show the history of countries, states or provinces traveled.
Added features allow users to download their maps, to blow them up to posters of any size printed with media of any standard size such as A4 or letter size paper; and to get permanent URLs of their made maps in order to come back and further annotate them at a later date.
A program to orthorectify (correcting scanning distortions) and stitch images of gridded paper maps. The expected use is to correct and join several smaller (e.g. A4) scans of out-of-copyright large paper maps for display in a GIS or on the web.
