Note: this project should be done in combination with #24 to develop an overall dashboard/map application for a colocate GUI. Interested students should submit applications that consider both this issue #16 and #24 together.
Presently, the colocate-dev notebook uses HoloViz & DataShader to display nearly unlimited features on a slippy map.
See the Binder link for a preview: .
Example graphic:
The code backing the DataShader-based map is in the plot_datashader() function in plot.py. It is messy/WIP code that needs to be revised, and also recent releases of HoloViews have enabled many new capabilities for DataShader maps such as hover, colorbars, and dynamic color maps and more that would improve our map presentation.
Some simple improvements to the plotting interface might be:
enable hover functionality with relevant attributes like dataset ID, lat/lon, etc
add a legend to the plot showing dataset ID
figure out how to increase marker size to better show single-point datasets that are drowned out by trajectories
More advanced changes:
enable user to dynamically select datasets to plot from query results table
other dynamic plotting capabilities (varying plot display based on CF featureType for example)
Expected Outcomes:
An improved HoloViz map display that better displays ERDDAP dataset results and might integrate better with other dashboard-like capabilities planned for the project (#24)
Skills required:
Python: HoloViz, DataShader, Panel API familiarity especially
Difficulty:
Medium
Student Test:
Fork the repository
Run the colocate-dev.ipynb in Binder to get an idea for the current DataShader map display in the output of Cell 12
Improve the code in colocate/plot.py plot_datashader() so the map is able to meet one of the 'simple improvements' listed above
Push your changes to your GitHub fork and post a link to run your modified colocate-dev.ipynb notebook in this issue
