These short videos and notes are intended to provide some help in getting started with GWSDAT on-line. In order to see the details of a video, start the video and then press the button on the control panel at the bottom to run it in full screen mode.
More extensive notes and resources will be provided here shortly.
Example data sets in different file formats
The example data sets included in the online and local versions of GWSDAT can be downloaded separately in various different file formats below. These files can be used to explore the variety of different data input options in the online version of GWSDAT.
Running GWSDAT locally
If security is a concern, GWSDAT can be downloaded to run on a local machine.
Groundwater monitoring data is entered into GWSDAT by means of a standardised Excel input sheet. The illustration opposite shows an example. The template has been designed with simplicity in mind. There are only two input tables that must be completed, namely, the Historical Monitoring Data table and the Well Coordinates table. Please ensure that there are no empty rows in these data input tables.
An additional GIS Shapefiles table may also be populated with links to the location of GIS shapefiles for use as basemaps or site plans.
An Excel sheet can be uploaded from the Manage Data item on the sidebar menu, using the Import Excel File or Import .csv Data buttons. Two example sheets are already provided in the application so these can be used to experiment with the facilities of the tool.
Analysis is launched from the Analyse item on the sidebar. Once the dataset of interest has been selected, a variety of options are available from the menu bar at the top of the page. These include Spatial Plot, Time Series, and Trends and Thresholds. At this stage everything is controlled by the menu items, checkboxes and buttons available on the page for each type of analysis.
Particular plots of interest can be saved in a variety of formats. One particularly useful facility is the ability to save a sequence of spatial plots to a MS Powerpoint file. This is available from the Generate PPT animation button at the foot of the image displayed on the Spatial Plot page. Pressing this button will create and download a .pptx file.
Saving the session
It can be helpful to save the current session. This facility is available from the Save Session item of the More menu. Selecting this option creates an .rds (R format) file for downloading, with a name of your choice.This file can later be reloaded into GWSDAT on-line through the Load Data button on the Manage Data page.
