About:
A tool to add points to a map from csv or shapefile, and interactively cluster them as you see fit, this GUI driven, geographic database display and clustering application built is built on R. Is also a nearly minimal example of how to tie map and database together, how reactive shiny elements work, and how to print dashboards. A project that grew out of a request to see a database from a geographic prospective, here is a FOSS implementation of GIS for people who don't know or have the time to learn it.
Features
- GUI driven interface to select csv or shapefile database.
- Use drop downs how to cluster (currently broken), color, and label the points.
- Edit the table view of the database and optionally save the database back out.
- Click on a table entry to zoom to the location
- Fully reactive map and editing
How to run:
The "installation" of this is program is trivially easy by design and requires no permissions. To start the process:
- Download and unzip this repository using the green "Clone or download" button.
- Select a csv or a shapefile, enter the LAT LON and EPSG fields as necessary. Replace spaces with .
- and hit run!
A test dataset is included in the data folder. To "uninstall", just delete the folder. Pandoc and PhantomJS are also installed, and may be removed through the add or remove programs system dialog and the user/AppData/Roaming folder respectively.
Known bugs:
- Selecting fields which are too long or numeric will currently kill the crab. To recover, close the window and re run the HTA.
- Map and data don't wrap smoothly.
- Fly to (when you click on a row) will sometimes cause the server to lock up. To fix, zoom in a bit before attempting to fly.
- Legends can be too large for the window.
- Print button works but output is gross.
- Map legends are also not printed.
- Pandoc needs to restart after being installed, so attempting to print after the installation will break the server. To recover, close the window and re run the HTA.
- Editing the table is not fully tested.
- Shapefile editing broken.
