Description

This app facilitate digitizing data points from a given figure.

The digitizing workflow in this app is:

1. Select a figure with data points of your interest.
2. Choose and tune a coordinate system to fit your figure.
3. Add and edit point groups and choose a group to work with.
4. Move the cursor to each data point, then tap the cross hair button to record its coordinates.

Apart from non-geographic coordinate system such as the linear and the polar axis, this app also provides 23 major map projections. These map projections are essential when the target figure is presenting geographic locations. For example, locations of geological observations, species distributions in biology, GPS tracking results, air quality informations, etc. The 23 major map projections are, of course, not inclusive: some map projections don't have an easy way to calculate and present. The app author will try to include more map projections in future updates. Here lists the available 23 map projections:
