Version 1.3

Introduction The Queensland Emergency Risk Management Framework (QERMF) Risk Assessment Tool (RAT) is an ArcGIS Online product created by the Hazard and Risk Unit, Queensland Fire and Emergency Services. The RAT contains spatial data designed to assist with disaster management hazard identification, risk assessment, and planning (Figure 1). It contains a collection of spatial data from various sources, with access restricted to nominated users due to some data being commercial-in-confidence.

Figure 1: Introduction page of the QERMF Risk Assessment Tool

The RAT has been developed with an iterative approach in mind. This means that new features will continue to be added, with new and/or redesigned topics, layers, and analytical functions. Functionality of this tool and positive user experience is crucial to its ongoing use and success, and any user feedback should be sent to the Hazard and Risk Unit at [email protected].

GIS platform overview

Heading overview

Figure 4: QERMF Risk Assessment Tool app heading tabs.

There are 8 heading tabs within the Risk Assessment Tool (Figure 5), each with a different purpose:

1. Introduction. Outlines the steps in the risk assessment process 2. Tropical Cyclone. Provides an overview of the tropical cyclone hazard, and a

number of spatial layers that can be used to query and analyse hazards, exposures, and vulnerabilities

3. Severe Thunderstorm Event. Provides an overview of the severe storm hazard, and a number of spatial layers that can be used to query and analyse hazards, exposures, and vulnerabilities

4. Bushfire. Provides an overview of the bushfire hazard, and a number of spatial layers that can be used to query and analyse hazards, exposures, and vulnerabilities

5. Earthquake. Provides an overview of the bushfire hazard, and a number of spatial layers that can be used to query and analyse hazards, exposures, and vulnerabilities

6. Heatwave. Provides an overview of the heatwave hazard, and a number of spatial layers that can be used to query and analyse hazards, exposures, and vulnerabilities

7. Demographics tool. Provides detailed spatial information on demographics in Queensland using data from ESRI and the Australian Bureau of Statistics. This information can be used to identify and assess demographic exposures and vulnerabilities from an all-hazards approach, or in conjunction with risk assessment for a specific hazard

8. Climate Change in Queensland. Provides an overview of future climate projections for Queensland. Climate change projections should be considered in risk based planning, as the interaction of climate change with other hazards will have significant planning implications for built and natural environments.

Widget toolbar The buttons or tools available in the app are known as widgets. These widgets provide a range of functions. The functions of the widgets in the Risk Assessment Tool are described below and shown in Figure 6.

Legend

The Legend widget displays labels and symbols for layers active in the map.

Layer list

The Layer List widget provides a list of operational layers and their symbols, and allows you to turn individual layers on and off. Each layer in the list has a check box that allows you to control its visibility. Some layers contain sublayers or subtypes.

Add data

The Add Data widget enables you to add data to the map by searching for layers in ArcGIS Online or Portal for ArcGIS content, entering URLs, or uploading local files. In this way, you can temporarily add layers to and remove layers from the map. However, you can't save the layers to the map.

Situational awareness

The Situation Awareness widget allows you to specify a location on a map and analyse information from feature layers within the specified area. This widget is especially helpful for conducting creating exposure reports for an area, and is discussed in more detail further on.

Analysis

The Analysis widget provides an easy way to use ArcGIS Online or ArcGIS Enterprise spatial analysis tools in your application. A description of the function of each analysis tool is available by clicking the question mark icon next to each analysis tool. A more detailed overview of the various analysis functions can be found here.

How to use the map tools

Layer List tool To activate a layer in the list, check the box to the left side of that layer. Clicking on the arrow next to the check box will show another list of attributes and check boxes, or it will show the legend associated with that layer (See Figure 7 for more details). Layers that are greyed out are not visible at the map extent being viewed. Greyed out layers will become visible when you zoom in closer. Clicking on the ‘…’ icon to the right of each layer will open a list of options for that layer. Enabling or disabling pop-ups is a function you should keep in mind when querying map objects.

Add data tool

The following steps outline how to add other layers to the map view.

1. Click on the “Add Data” tool (Figure 8)

Figure 7: Add data tool highlighted on the widget toolbar, in the Severe Thunderstorm Event tab

2. There are three ways to add data – Search, URL, or File. a. Search. Click the drop-down menu below the search tab (Figure 9) to search

by either personal layers (My Content), organisational layers (My Organisation), or layers published by ArcGIS (ArcGIS Online).

More information on the layers

You can find descriptions and metadata for each of the layers by clicking on ‘Show item details’ (last dot point in Figure 7). This will open a new tab with a description of the data, along with a URL link that you can use to add features to your own maps.

b. URL. Use this tab to add a URL (web address) from the following types:

i. An ArcGIS Server Web Service ii. A WMS OGC Web Service iii. A KML File iv. A GeoRSS File v. A CSV File.

c. File. Use this tab to add data by drag-and-drop or click on browse to locate a file in your own folders. Accepted file types are:

i. Shapefiles (.shp) ii. Comma-separated values (.csv) iii. Keyhole Markup Language (.kml) iv. GPS Exchange Format (.gpx) v. GeoJSON.

Situational awareness tool The situational awareness tool allows you to select an area on the map and analyse information from a number of layers within the specified area – for example, demographics, buildings and infrastructure, community services, and public health facilities. This can help with the identification of features to enable more detailed risk assessments, as well as with scenario planning.

Using the situational awareness tool

The example below uses the situational awareness tool to assist with scenario planning for a current or potential flood warning issued by the Bureau of Meteorology. You can use

your own organisation’s data, open source data, or data hosted by the Public Safety Business Agency.

1. Click on the ‘Add Data’ tool, and in the search bar type in ‘BoM Flood Watch and Warning’ (You should add the data relevant to your own analysis). Click on ‘ADD’ once the layer appears in the search column (Figure 10).

Figure 9: Adding data to the map in the Tropical Cyclone tab

2. Click on the ‘Layer List’ tool, and scroll down until you find the layer you just added.

Click the check box to toggle between visible/not visible. The arrow to the left of the check box will open the legend, or layer subsets if available (Figure 11).

4. Alternatively, you can click on the ‘Situational Awareness’ tool, and then click on the

‘Draw Polygon’ button (Figure 13). This will allow you to draw a polygon around the query area using several points. Double click at a point to close the polygon and stop drawing.

Figure 12: Selecting the situational awareness tool from the widget toolbar, and selecting the draw polygon function

5. Once you have closed the polygon, a number of tabs will appear at the bottom of the screen, containing attribute data from pre-selected layers in the layer list.

Note that where the polygon drawn intersects a feature, data for the entire area of that intersected feature will be added to the situational awareness summary. This is apparent in the Figure 14, showing the full extent of Powerlink high voltage power lines that intersect the polygon drawn. You should also be aware of this when querying the demographics data, as the ABS demographic areas can extend well beyond the area drawn using the situational awareness tool.

Analysis tool Using the analysis tool will consume credits purchased by your organisation. Service credits are the currency used across ArcGIS and are consumed for specific transactions and types of storage such as storing features, performing analytics, and using premium content. You should only use the analysis function if you are familiar with ArcGIS and have a specific need to conduct a geoprocessing function. Many of the simple query functions required to identify exposed and vulnerable features can be done using the situational awareness tool. You can access the analysis tool by clicking on the ‘Analysis’ button. A list of the analysis tools available will be displayed. Clicking the question mark icon next to each tool will bring up a brief summary of the tool’s function. You can learn more about the functionality of each analysis tool by clicking on ‘Learn More’ at the bottom of the pop-up window (Figure 16).
