Welcome to the Chicken Creek online data portal

With this portal you can find, visualize and save measured data from Chicken Creek catchment. The datasets contain measured data from wide variety of sensors installed in the test site, as well as data obtained from laboratory. The portal includes different main panels namely, Help, Information, Map, Time Series data, Vegetation data, and Aerial Photos. The user is able to back and forth between different main panels using the left sidebar panel.

The data portal includes the following main panels:

1-Help: contains data portal instruction.

2-Information: contains information regarding each main category such as definition of some parameters, measurement procedure, abbreviations, and … etc.

3-Map: designed to observe the Chicken Creek satellite map, enabling to locate measurement stations on the map and obtaining related information for each point.

4-Time Series Data: this panel has been designed to provide an easy access to the time series data along with possibilities to visualize and save them.

5-Vegetation Data: the aim of this panel is an easy access to the vegetation data, as well as exploring and saving them.

6-Aerial Photos: Aerial photographs of the Chicken Creek catchment taken at different times, presenting changes in the surface structures.

7-Sampled Data: This panel permits to access physical and chemical soil properties collected through sampling.

Map:

The Chicken Creek satellite map can be observed by this panel. Different measurement stations are visualized on the map by selecting the main categories in the upper right part of the map. Each category represents a specific dataset. By clicking on a measurement point, a popup window will be opened on the map presenting the location name. In the meantime, a table will be opened below the map providing all necessary information regarding the selected measurement station. By clicking on “Download Coordinates”, one can download and save coordinates of the sites in the selected categories. In order to find locations of the measurement points on the map, select your preferred positions from the list and click on search button. Afterwards, the selected positions will be appeared on the map. Also “Reset map” button resets all selections made by the user to the initial defaults. To save coordinates of the selected positions, click on “Download Coordinates”.



Time Series Data:

This panel allows for handling the time series data considering past and current measurements.


Parameters:

This panel permits to choose parameters for later applications. It consists of the following main parts:

Select Parameters:

In this panel, the user is capable of selecting different main categories each of which represent a specific dataset. Each main category is divided into some sub-categories which contain the parameters. This panel has been designed to provide an easy back and forth between different main categories and sub-categories to select the parameters. The time series data have been provided with different measurement intervals that can be selected from each main category panel.

Select Date Range:

The “Select Date Range” permits to choose the date period for the selected parameters.

The parameters have different starting and end date, as well as different measurement interval. It is important to note that if parameters with different time vectors are selected by the user, the routine combines them together using a merging algorithm and produces one time vector for all of them. As a result, all of the selected parameters will have the same vector length.

Basic Statistics:

This panel includes two main parts: “Apply Functions Over Time Series Periods” and “Apply Functions Over Time Series Parameters”. By activating the first part, one can apply some basic mathematical functions on the data considering different time steps. For instance, if the user is interested in averaging data related to each selected parameter using a specific time window, he/she should select the time window from “Select Time Step” and “Average” function from “Select Function” boxes, respectively. By activating the second panel, the user is able to apply the functions on the parameters together. For instance, by selecting the “Average” function, the program calculates the average of the selected parameters that can later be seen in the “Time Series Plot” along with the data. If the user selects the “Exclude Selected Parameters” box, only the averaged values will be considered (for saving and plotting) without selected parameters.


Visualization:

This panel permits to observe data. It consists of the following main parts:

  • Time Series Plot: to see time series data.

  • Correlation Plot: to see correlation between different parameters.

Time Series Plot:

Save Data:

The routine allows for saving data (selected parameters) with excel, text and csv formats choosing from “Select Format” box. In the “Enter File Name” box, the user can enter the file name which has been selected as “data” by default. If the user desires to save missing values as blank, he/she should check “Set Missing Values to blank” box otherwise the program considers character values for them. By pressing save data button, the selected parameters along with the time vector will be saved considering the selected format and file name.

Note:

For monthly data the measurement dates are presented with day.month.year format which means data related to the entire month. For instance, 01.02.2011 means data for the whole February 2011. The same rule is applied for the yearly data (01.01.2011 means data for the entire 2011).

Setting For Plot:

In this panel, one can select graph background color, line color, line width, title and y axis label from “Background Color”, “Line Color”, “Line Width”, “Title”, and “Y Label” boxes, respectively. The line color options are presented in figure 1. Usually, when the graph encounters a missing value in a data series, it interprets this as a gap and draws it as such. If the “Connect Separated Points” box is checked, the gaps will be connected in the graph. It is hard to plot and observe the temporal variations of data with different scales. If “Normalize Data” box is checked, all data will be normalized between 0 and 1 making it possible to compare trends of the parameters.

By pressing “Plot Time Series” button, one can observe the selected data in the bottom box. The legend appears at the bottom of the plot. In case of any changes in the selected parameters (adding/removing the parameters, change measurement interval, and … etc.), the user should press “Refresh Plot” to see the changes in the graph. The “Download Plot” button allows for saving the plot in “png” format using the title as a file name. The graph allows for both vertical and horizontal zooming by mouse dragging on the plot. By clicking on the “Reset Zoom” button appearing on the graph, one can return to the default zoom. Horizontal zooming is also possible by changing the selector settled at the bottom of the graph.

Correlation Plot:

Save Data:

This part allows for saving correlation matrix in excel format. In the “Enter File Name” box, the user can enter the file name which has been selected as “ correlation” by default. By pressing save data button, the correlation matrix will be saved.

Setting For Plot:

In this panel, one can select graph background color, graph color, correlation method, and plot method from “Background Color”, “Graph Color”, “Correlation Method ”, and “Plot Method” boxes, respectively. The graph color options are presented in figure 1.

By pressing “Plot Correlations” button, one can observe the correlation between different parameters in the bottom box. The legend appears at the right side of the correlation plot. In case of any changes in the selected parameters (adding/removing the parameters, change measurement interval, and … etc.), the user should press “Refresh Plot” to see the changes in the graph.

In order to start a new scenario, press “Reset All Selections To Default” button to reset all selections to default (top of the panel). Afterwards, by pressing the “Refresh Time Series Plot” and “Refresh Correlation Plot” buttons, both graphs will be cleared. These buttons has the same functionality as “Refresh Plot” in the “Time Series Plot” and “Correlation Plot” panels and the user can also use them to refresh the plots, regularly. Note that, the user is able to save data even without visualizing them with the merged time format explained above.

Vegetation Data:

The vegetation data are presented in tabular formats allowing for exploring and saving them. There are two main tables to show the vegetation data:

  • Table 1: based on species names.
  • Table 2: based on main categories.

In the “Setting” panel, the user is able to select Quadrant (see information panel), Grid Cell, Species Names (for Table 1), Main Categories (for Table 2) and Year of the measurements. To see data based on species names, the user should go to “Table 1” panel. After selecting a preferred setting, press “Refresh Table” button to see data in the bottom table. The user is able to explore vegetation data based on main categories by going to the “Table 2” panel. After selecting a favoured setting, press “Refresh Table” button to see data in the bottom table. In the “Main Categories (Table 2)” panel, there is an option called “Summation”. By activating this option, summation of the cover values for all selected main categories are calculated by the program which can be seen in the table by pressing “Refresh Table” button. The user is able to save data as an excel format by pressing “Save Data” buttons. Also, the “Reset All Selection To Default” button resets all selections made by the user to the initial defaults.

The data portal allows for plotting the cover values versus time considering main categories. To do so, you should select Year, Quadrant, Grid Cell, and Main Categories (Table 2). Afterwards by pressing “Plot Vegetation Data” you are able to see the values. You should notice that the plot works by selecting just one Quadrant and one Main Category. In case of multiple selection of Quadrant and/or Main Category, no graph will be displayed. The legend of the graph shows the Grid Cells. In the “Setting for Plot” panel, the user is able to select Background Color, Line Color, and Line Width. By activating “Calculate Average” box, the average of the data will be included in the graph. By activating “Exclude Selected Parameters”, only the average value will be displayed. One can save the graph by pressing “Download Plot” button.

Note:

Since Table 1 and Table 2 require multiple selections of the setting parameters, the user must select year, quadrant, grid cell, and Species name (or main categories for Table 2) all together to be able to see data. Otherwise, no data will be displayed.

Show vegetation data on the map:

The “Map” panel of the data portal allows for observing vegetation cover values on the map. To do so, in the “Vegetation” panel, you should select a specified year, Quadrant 0, Grid cells, and your preferred species. Then in the “Map” panel, press “Plot Vegetation Data”. Then the cover values will be appeared on the map as circles. The size of the circles represents the cover values. This allows for better exploring the vegetation covers for the subsequent decisions regarding the growth rates of the specified plants. Note that the program considers only the Quadrant 0 and the other Quadrants are automatically discarded.



Aerial Photos:

This panel presents the aerial photos taken at different times. After selecting your preferred figures or video, click on “Save Selected Items” button to save them as a zip file.



Sampled Data:

This panel includes data from different soil samplings. Depending on the application, the user can select different sampling or nested sampling data. Each section includes different parameters that the user can select based on his/her need. The bottom tables allow for data visualizations. By pressing the “Reset All Selections To Default”, all the selections will be reset to the default values. The “Save Data” buttons allow for saving sampled data as a excel format.



Authentication:

The Chicken Creek data portal was constructed with a facilitated graphical representation, allowing for flexible, user-friendly and efficient illustration of the parameters. The graphical presentation and image storage are open to all users. But the data accessibility is restricted to the internal and authorized external users. As a result, the data storage and tables are password protected.
