Vega Data Model Core

Vega Datamodel Visualization and Retrieval Tools

dbBadger

dbBadger retrieves and temporally synchronizes data from the Vega datamodel. It includes functionality to output unsynchronized data, temporally synchronized data, interpolated data, and time-weighted aggregated data.

 

VegA Data EditoR(VADER)

VADER is a java application designed to very quickly and efficiently retrieve large amounts of high-resolution sensor data. Its functionality is similar to dbBadger but should have much improved query times. 

 

Vega Site Overview

This tool is a quick and dirty tool for viewing graphed data from Vega grouped by site. It is primarily utilized for manual tech monitoring of sampled variables. All available hi-res streams are plotted. Note: Hi-res water-temp profiles for some sites can be slow to render as they represent a high number of datapoints (over 200,000 from Mendota Buoy). This tool is built upon vegaPlot, described below.

VegaPlot

            vegaPlot is a tool used to quickly and easily create simple timeseries plots of data stored in Vega. In addition, these plots can be quickly added to an existing website by linking their full address in an html ‘img’ tag. All information pertaining to the data to be plotted must be provided in the query string. Controlled vocabulary is used to specify parameters. Examples are shown below. All graphs are rendered by the ‘vegaGraph.aspx’ page.

 

This graph plots airport air temperature for the last 10 days. It uses a relative timestamp to always plot the time interval ending with today.

This graph uses an absolute timestamp to plot the air temperature between 11/1/2007 and 11/9/2007.
