SUPERSLR Sebastian GeoData System

The Sebastian geodata system is designed to provide a complete geospatial tool set and easily extensible model for SUPERSLR analysis. A database is provided with a Google Earth interface, which contains wiki-like functionality for Port Data, Port Polygons, and Notes. Access to this system requires a user-specific KML file. If you have already been subscribed, please use the form below, otherwise, please e-mail us (sebastian@underwatershipping.com). Full documentation and help is available on this wiki.

Main Interface for Port Charactersitics, showing "Add Port Polygon" and "Add User Note"

(Cross-posted in Basic Help & Introduction)

The Sebastian geodata system is based on the principles of cut/copy and paste. Geometries (points, paths, and polygons) should be drawn using Google Earth's built-in tools (see the Google Earth User Guide for more information: Placemarks, Paths and Polygons). After creating these features, a simple cut or copy action prepares the feature for entry into Sebastian. Clicking on an existing feature (such as a Port with a ferry icon), then choosing “Add Port Polygon” or “Add User Note” for polygons or points, respectively, which should promptly open a form where a paste action into the field titled “Paste new KML” completes the entry. Please note that all other available fields must be filled out, and the submit button must be pressed in order for the submission to occur. All data additions, edits, deletions, and model runs will receive a response message indicating if the action was successful or if there was an error.

Editing an existing geometry is similar to adding a new feature. Create a new geometry using Google Earth's built-in drawing tools (as above), then cut/copy the new item. Next, click on the feature you wish to edit, choosing the edit option (i.e., “Edit Port Polygon”), and fill out the form as described previously.

Information associated with a feature, sometimes called “Metadata” in GIS, may be viewed and/or edited if a “View/Edit” option is available in the item's balloon upon clicking the feature.

About the code

Written in pure Python, this system could be run on any operating system with Python and the MySQL database module installed. The system currently runs on the underwatershipping.com server, running home-grown, customized Linux distribution by DreamHost and a MySQL database.

A beginner's guide to Python is available here.

Current Status

The Sebastian geodata system is fully operational. Access to this system requires a user-specific KML file, which may be obtained by e-mailing us (sebastian@underwatershipping.com).

For visitors, all editing privileges are disabled, and the KML access file may be downloaded here.

Note: Some users report that this file downloads with the extension ”.py”; please change or add the extension so that it ends in ”.kml” for use in Google Earth.
