In the map of recent earthquakes below the symbol size is indicating the magnitude of the earthquake. If you have an attribute-based symbology set for your layer, this carries through to the clustering. The Clustering tool in the new Map Viewer gives us a lot more flexibility and control over the information available for the clusters. Ta daaa! Cooler clustersĬlustering is a great way to dynamically aggregate incident data. Oh, and if you have a layer with attached images it will default to including an Attachments Gallery, that displays the images in the pop-up and in the right orientation. In the example above the All mapped value is a simple sum of the fields shown in the pop-up and is used for the predominant colour symbology. You can of course create Arcade expressions to enhance your pop-ups. It’s really easy to choose what attributes to include and what they are called. In the current Map Viewer there are options to customise a pop-up, but it becomes so much easier with the new Map Viewer. Pop-ups are an integral part of accessing information in web maps or apps. If you’re using a rotated map view – yes you can rotate your seaside maps – you can even set it to save the rotation. Not anymore – or at least it’s now your choice. When you open it at the saved extent half the layers are hidden because the scale has changed. You save it and take it out and about in an app on your mobile. Imagine you carefully set up your layer visibility ranges and your labelling to be nice and clear when you open the map on your monitor. When you save a web map in the new Map Viewer you get the option to save at a fixed scale. So many options and although performance may become a limit the instant feedback makes it easy to spot if you are going too far. I used the same attribute in my label classes, but you could have different information visible at different zoom scales.

In the example below, I used these to add labels that use Arcade to round the target attribute and then show the rounded value at different sizes above and below a threshold value – half the population in full time employment:Įvery change you make instantly updates the labels, so it’s quick to spot that the yellow halos are a bit overkill and revert to something more subtle. Each label class has its own visibility range, its own style, and its own optional filter. As well a much bigger library of fonts, you can also set up multiple label classes. The new Map Viewer makes setting up effective labels really straightforward. You can explore these maps interactively here, along with more thoughts on the choices. Switching to the new Map Viewer allowed me to create a more nuanced map that visually represented the runners up too: But every map style has its drawbacks and this was giving me a first past the post visualisation. For a project looking at employment patterns, I used the predominant category option to highlight regional dominance. Presenting data sets that have multiple attributes in a map has always been a challenge. For the new Living Atlas UK earthquake data I’ve been looking at I set the threshold to magnitude of 2 – it defaults to the mean value and you can either slide the bar or double click on the value to set your own value. The above and below mapping option is taken to another level with the ability to combine colour and unique symbols to emphasise the values above or below a threshold. I’d have put that one at the top of the list to remind us all to consider it first. They are categorised by use case and it’s great to see colour blind friendly as a filter for colour ramps in the dialog (see below). The new Map Viewer gives a much bigger library of colour ramps to use, so we can better fit the symbology of our data to the rest of the map contents. We’re all familiar with using colour ramps to show relative value differences for data attributes in a map. Add a layer to a group, rename it and drag the other layers in… that simple. This may well be the most asked for feature in web maps, but they are coming. I’m sure lots of you have already taken the beta for a spin to see what cool new features you get for your web mapping, but I thought I’d take you on a tour of what’s coming… Group layers We are eagerly awaiting the new Map Viewer coming out of beta – planned for the Spring ArcGIS Online update.
