Quick Start

00:02: In this short video, we will show you how to get started using VegMachine

00:06: with a simple example.

00:13: Firstly, if you're in Queensland, select the Queensland region button

00:17: to access more products and tools.

00:22: Define a feature area of Interest by using the drawing tools.

00:26: You can either select a one hectare point or define a polygon using

00:30: the polygon tool.

00:33: Define your polygon area of Interest by clicking on the map creating

00:37: a series of points.

00:41: You can complete the polygon by clicking on the first point again.

00:48: Select the polygon by clicking on the marker.

00:54: Click on the "Chart" button to open up the chart menu.

00:57: Select a data subset from the menu.

01:02: Select the product you want to analyse from the list of available products.

01:07: Product details are available via the "info" button to the right of the product name.

01:11: After a short period a chart will appear showing the time series

01:16: data over your area of Interest.

01:19: The chart and map are synchronised.

01:23: Click on a point in the data series to load a map for that date.

01:30: Once the map for your selected date has loaded, you can use the map tools

01:34: to change the elements of the display.

01:37: Here you can step through the maps by using the time series date slider tool, or

01:41: by clicking on a different date in the chart.

01:45: The chart data is available to

01:47: download through the chart download button.

01:51: More tutorial videos are available under the

00:27: A drop the marker at your site.

00:32: To select the marker for analysis, click on the marker.

00:36: The map will zoom to the selected area.

00:43: To activate the charting functionality, click twice on the chart button.

00:49: The chart menu will display.

00:53: If you are in Queensland, select the Queensland region button to

00:57: access additional products and tools.

01:01: Selected data subset from the menu.

01:05: To access Link to Metadata

01:08: about the products, click on the info button next to the product name.

01:13: Click on the chosen data set.

01:17: The data extraction will begin.

01:20: This typically takes under one minute to complete.

01:24: The time series chart will display.

01:29: To display the time series values for a date, click in the chart area.

01:34: The map and chart are synchronized. By clicking on a

01:38: data point. The corresponding map layer for that date will display. The

01:43: pink line indicates the date displayed on the map.

01:46: Navigate to the map by clicking on the display button.

01:52: You can adjust the layer display and view a legend using

01:56: the map tools.

01:58: You can move through the time series on the map page using the time

02:03: slider tool.

02:05: You can download the chart data from the chart page through

02:09: the download data button in the top right corner.

02:13: Use the mobile share button to share or save your results.

Defining Feature Areas

00:03: To extract data we need to define regions or "areas of interest". To begin, zoom into your selected area.

00:08: To define a region with a boundary, select the Polygon tool.

00:11: Define the polygon by clicking on the map around the your region.

00:23: You can define multiple areas.

00:46: You can instantly add 1 ha points using the "Marker" tool.

00:49: A single click on the map will add the marker

00:52: There are two modes for feature selection - individual features or multiple features together. This button switches between the two modes.

00:55: When single select mode is selected, clicking on a feature will select that feature and deselect all others.

00:56: Additionally, the map will zoom to the selected feature.

00:58: The zoom buttons will zoom in and out between the region/all existing features/selected features.

00:59: Clicking on the zoom out button takes as back to a view where we can see all features.

01:01: Clicking on the "Feature Select Mode" button again, switches to multi-feature select.

01:04: Now clicking on a second feature selects both features.

01:07: Now all features are selected.

01:10: Created features are persistent and will stay on the map until deleted, even if the browser is refreshed.

01:11: To delete a feature click on the "Trash" icon.

01:13: Delete a feature by clicking on it.

01:16: To permanently delete, select "Save" from the delete tool menu.

01:19: To delete all features, select "Clear All".

Data Collection

VegMachine collects no personally identifying user information. However, we do use Google Analytics to obtain statistics on usage and also collect polygon geometries from user queries. This information helps us improve our time-series-layers and service.

Map Server Down

VegMachine's web map server is not returning the requested overlay.

Data extraction and chart creation should not be affected.

This is typically an intermittent problem and should resolve shortly.

Data API not Responding

VegMachine's data extraction API is currently not responding.

This may be due to delays recalling imagery. Additionally, if you have requested multiple datasets for multiple features, the API may be timing out.

Please try again shortly and if the problem does not resolve contact terry.beutel@dpi.qld.gov.au

VegMachine Test Site

Welcome to the new VegMachine test site. This site will eventually replace the current VegMachine site located at vegmachine.net

This site is under active development and is continuously being updated. Due to this, occasionally features may be updated or withdrawn without notice.

We welcome feedback through the survey link found under Support in the main menu or by directly contacting Terry at terry.beutel@dpi.qld.gov.au

Multiple Features Select

The multiple feature select button has been activated as you have multiple features drawn on your map.

The button is on the left map toolbar and has this icon .

When not activated the default feature selection is a single feature at a time. Clicking the button allows multiple features to be selected at once. These multiple features can either be treated as a single area or as separate regions depending on the chart mode you select.

Mobile Browser

Vegmachine is designed to work on mobile devices as a web-app and will not be fully functional in the browser.

To install VegMachine as a web app share this page with your home screen.

Do not show this tip again.

Draw Features

Use the polygon and point draw tools to define areas for data extraction. In addition to drawing features, you can import vector files using the 'Import Features' tool under 'Map Tools' in the main sidebar on the left.

You can delete features using the delete tool.

Once you have features on the map, you can select a feature by clicking on it and can then extract data and create a chart. Selected polygons will be shown in pink and unselected polygons in blue.

Do not show this tip again.

Time Series Map Tools

Use the tools displayed in the bottom right of the map screen to:

Display a legend
Change the map overlay transparency
Toggle the display on/off
Step through different dates in the time series

Vegmachine utilises map tile caching. The initial display of a data product over an area will be slower than subsequent requests.

Do not show this tip again.

Synchronised Chart

This synchronised chart has a number of interactive features:

You can toggle series on or off using the chart legend.
Hovering or clicking on the chart at a point of interest will display the data value.
The map overlays are synchronised with the chart. By clicking on the chart the relevant product at that date will appear on the map page. The pink line represents the date displayed on the map.
You can download the chart data, image and vector file of features from the export menu at the top right of the chart
