I am a geographer on ArcGIS Living Atlas team. I work on policy maps, which help people see where a problem exists, where there is an opportunity to intervene, what possible solutions are under consideration, progress in implementing a solution, and latest results. Much of the effort in making maps is about fiddling with the software and data, but in my experiences, the best maps come from a conversation among policy makers/business leaders, subject matter experts, and GIS staff. If you wait for that meeting to happen, you might be allowed to make some policy maps (maps of action, maps that inspire action). If you cause that meeting to happen, you are a policy mapper. Most of my energy is spent getting people to see the gaps that exist among people and the problems they want GIS to help solve. Closing those gaps is fulfilling work and within your reach.

Also of interest on this topic: the Human Geography series of basemaps in Living Atlas all put the country borders on the "Details" layer, which you can turn off at will.

I am a user of their layers as well. But I don't know if/when they plant to offer a time series version of the data. This mentions why active cases are an attribute in some layers but not populated for all areas. See the FAQ or contact Johns Hopkins for more information.

Good way to find them is the ArcGIS Living Atlas app. Here's a link to a search for the Dark Gray basemap (a webmap), its base layer and its reference layer. Plus some other things.

Annie, thanks for asking about this. Short answer: I recorded this video a while back to demonstrate how to anchor a map around a meaningful value. Check it out at about the 8 minute mark to see an example of how to anchor a map in a specific value. Slightly longer answer: We have definitely noticed that many GIS users will make a thematic map and simply accept the software's default suggestions, for classification approach, classification breaks, and even colors. Yet, we noticed the thematic maps that are successful, popular, well-received tend to be the ones where the map's author considered what the audience actually knows about the subject. When the colors or sizes on the map mean something, people tend to understand the map instantly. So how do we move beyond software defaults and inject meaning in the work? In that blog, I talk about "anchoring" the map in a meaningful value. If you are using Natural Breaks as a classification method, apply color to specific classes, whose breaks each have meaning. The US median income is $46,533, so that needs to be one of the class breaks, somehow. The standard deviation method is a big help in that it tells you what breaks look like at 1 standard deviation from the dataset's average value... but the average of the data is most certainly not equal to $46,533, so use your judgement in how you apply the next breaks. Rounding up the break points is a nice way to make the map more friendly too. Class breaks are great when each break has meaning, but they are horrible at allowing the data to "breathe" so that your eye can detect the subtle variations in median income around the country or city. For many map subjects, a five class map is like reducing an image of the Mona Lisa to 5 colors. Some things get lost. An unclassed, continuous color ramp does an incredible job showing all the detail that classifications obscure. Using a continuous color ramp, you apply color across a range of values with 2 or 3 values that have specific meaning. In ArcGIS Online, it automatically sets one end of the color ramp you choose to the value found at 1 standard deviation above the mean of the data, and the other end of the color ramp to the value found at 1 standard deviation below the mean of the data. You can then adjust from there. I always recommend choosing the "Above and Below" theme in ArcGIS Online to see immediate benefits from this approach. Here's an example of classed vs unclassed on the same subject: Classed: 3 classes shown Unclassed: dark blue means significantly high % of seniors age 65+, yellow means significantly low

A quick workaround I've used on an iPad or browser: take a screenshot of the infographic and use that image. On iPad, hold down the Home button as you hit the Power button simultaneously.

We published a nice blog and story map to introduce a couple of new map styles in #smartmapping in ArcGIS Online. What’s New in Smart Mapping (March 2016) | ArcGIS Blog What is a Predominance Map? So, make some maps and post them in this discussion below!

You can email the item’s URL to me at jherries at esri and I can have a look. We have seen this issue occur when: a service is slow to respond a service is slow to return all the features requested at the default extent of a layer internet connectivity is having issues For the above cases, empty the cache, reload the contributor app page, and try your item again. Also view your item in ArcGIS Online's item page and map viewer page, to make sure all is working as expected. You do have a couple options to try to get a draw time score from a known, good layer: 1) when the Contributor app tries to draw your layer for the first time, quickly double-click on the map to zoom in. You may have to do this 2 or 3 times to “trick” the app into drawing the layer successfully at a scale where the layer is faster to draw 2) in the item page for your layer, choose Edit and manually change the layer’s extent to a small area, such as a neighborhood. Save the layer, and reload the Contributor app to see if it scores normally.

Good links provided above. I always clear selections from my layer and tables in cases like this, and check for network paths to data to see if the network is part of the issue. To troubleshoot, do Save As on the MXD once it's open, and remove one layer or table, save as new file name, repeat until you can isolate which layer is problematic.

The Dark Gray Canvas basemap is released (see the blog announcing it, with URLs to the basemap itself and its component base layer and reference layer). So, how do you use it well? Can you simply swap it in, and everything magically works with your map's main subject matter? Maybe. But just in case your thematic map isn't quite looking like you'd hoped on Dark Gray Canvas, read this blog and this blog from the map's designer, Andy Skinner. He explains how colors work well on top of a dark map, with lots of examples. Share your maps that use Dark Gray Canvas back to this thread, so others can benefit from your work! Jim

Tim, Thanks for writing. I�??d love to see examples of maps that aren�??t working for your purposes. Ideally, ones with and without additional labels. You can email me jherries at esri.com with examples. The Canvas reference layer is deliberately sparse with the labels. It has place name labels throughout, but we generally try to leave things out rather than fill in every blank spot on the map with a label. It�??s not a basemap where we try to fit in a label if there is room. We leave lots of room for the thematic content, which can range from local scale to neighborhoods scale to city scale to regional scale to national scale. The idea is to be minimalist about it so that others can add their themes, and whatever additional labels they�??d prefer, to the map. Labels on imagery are similar, in that a balance needs to be achieved between enough labels to give a sense of things, but not so many labels you can't see the imagery. Of course, there�??s always room and interest in improvement. Can you also share the source and location of the additional data you'd like us to check out? Thanks for using Canvas.

Hello, thanks for reporting these findings. A new version of the European cache is completed and progressing toward its release. I know that we did a bit of work in this region at the scales you are reporting concerns. I'll share your map of issues with the team to verify whether they are already addressed. An option to be aware of: the canvas map template is available for those who would like to build a better basemap for their country or local area, using the canvas map's various shades of grey, labeling approach, etc. Thanks for taking the time to share these items. Jim

That service is running again. You have my apologies for the inconvenience its outage resulted in on your end of things. I also wanted to notify you that this similar map is also available: http://www.arcgis.com/home/item.html?id=c734818dff56412bafd2a4a4ca61431b
