There are a lot of options for configuring choropleth maps. It’s tempting to just stick with the defaults and hope for the best. But a little bit of experimentation with these options can really improve your map. So long as you have a clear sense of what your map’s goal is, you can make smart choices and great maps. In the following video, I share five examples of choropleth maps made with a single dataset. It includes tips and techniques for designing maps with the Counts and Amounts (color) style in ArcGIS Map Viewer. Learn how to adjust a histogram, choose a color scheme, classify data, and, perhaps most importantly, assess how well your symbology works. Watch the video Click the image to watch the video. You can follow along with this video with the Maximum Building Height web map. The data used in the map and video is from Halifax Open Data.

A map's legend is not just a list of all its layers. It’s an important key to help people understand and interpret the map. You don’t need to be a fancy designer to make an excellent legend. Often, all that’s needed is a bit of tidying: renaming, reordering, and removing items. Below are three short videos that can help you tidy up your map legends. Improve layer names in a map Good cartography is not just about colors and symbols, it’s also about the words on your map. The symbols you chose may be excellent, but if the layer names describing them aren’t clear, the symbols won’t work. This video shares an example in ArcGIS Online of how to create clear and concise layer names. Improve a map legend One of the easiest ways to improve a map is to improve its legend. This video shares an example of creating a clear legend in ArcGIS Online. Remove layers from a legend Not every layer on your map needs to be featured in the legend. This video shares examples in ArcGIS Map Viewer and ArcGIS Pro. It demonstrates four times when a layer can be removed from a legend.

When people look at your map, what do you want them to notice first? Visual hierarchy is a design technique that lets people know which things on your map are important. Which of the three maps below is best? That depends on which layer is the most important to the map’s purpose. Each one uses visual hierarchy to emphasize one layer over the others. You probably already use visual hierarchy without realizing it: for example, if you made some map features a bright red color so they would stand out, or if you chose a gray basemap so it wouldn’t distract from your thematic data. However, the more you know about visual hierarchy, the easier it is to make effective and good looking maps. Below are three short videos I made about visual hierarchy. In these videos I describe some of the more common visual variable principles, and share some techniques for how to use them in your maps. If you want to follow along with the web maps shown in these videos, you can find them here: Visual hierarchy for maps Improve visual hierarchy with color Improve visual hierarchy with detail The data used in these videos is from Halifax Open Data.

@DougWolfinger2 Try using Unclassed Colors instead, that will give you a legend that looks something like this: Or you can use Graduated Colors to get a legend like this: In the Symbology pane, you can change the number of classes. You can also manually change the Upper value and Label for each class to rounded numbers, which makes the legend and the map easier to read:

Hi @PROBERT68 What you see on the Layout view is what you will get when you print or export the layout. However, the 1:1 button has no bearing on this. It just resets your zoom level to 100% The 1:1 button does not change the scale of your map. Zoom in and out on the layout and watch the controls in the bottom left corner. You'll see that scale does not change, while the zoom does change. If you click the 1:1 button, scale resets to 100%. Zoom is only for viewing on your computer screen. It has no bearing on printing or exporting. If what you see on the Layout view is not what you want to print, you need to change the scale of the map. You can set the scale of the map frame by double-clicking it in the Contents pane. This will open the Map Frame pane. On the Display Options tab, you can set the Scale. You can also change the scale by activating the map and zooming in and out.

Hi @EmmaHolt , The answer from @OscarHur above is correct - you can geocode your csv table. For more detailed instructions for geocoding, try one fo these tutorials: Convert a list of historic places into a map in ArcGIS Pro Convert a list of historic places into a map in ArcGIS Online Geocoding will create point data, and if you are mapping states, you may prefer polygons instead. For that, you can join your csv table to a spatial layer representing states. Try one of these tutorials to learn how to join: Join tabular data to a spatial layer in ArcGIS Pro Join a table to a feature layer in ArcGIS Online (If you don't know how to get the table into ArcGIS Online, see the geocoding tutorials above) For a spatial layer to join with, I recommend USA Census States from ArcGIS Living Atlas. (You can find this in ArcGIS Pro by searching in the Catalog pane > Portal tab > Living Atlas tab).

@Juan_Toro-Killion I am told that yes, you can use clone_items() to move content between any two organizational deployments.

Hi @eastrange1503 , you can start with searching ArcGIS Living Atlas, filtered to the United Kingdom: https://livingatlas.arcgis.com/en/browse/#d=2&rgnCode=GB. Here's the datasets they have related to flooding: https://livingatlas.arcgis.com/en/browse/?q=flood#d=2&rgnCode=GB&q=flood

It could happen if you're moving either the mxd or the data sources between sessions. Setting relative paths instead of absolute could help. This problem is also less likely to occur with ArcGIS Pro than ArcMap. If you're new to Esri products, I recommend you work with ArcGIS Pro instead. ArcMap will enter mature support next year and there will be no future releases. If your maintenatnce program is current, you already have access to ArcGIS Pro. You can learn how to get it here: https://pro.arcgis.com/en/pro-app/latest/get-started/faq.htm

@MHoagland have you already installed ArcGIS Pro? If not, find the .exe file you downloaded and follow the prompts to install the program. You can find more detailed instructions here: Install ArcGIS Pro. Once it is installed, click your computer's Start button and type ArcGIS Pro to find the application.

@MHoagland the responses above are correct, you should learn ArcGIS Pro, not ArcMap. Here are some tutoriaIs that I recommend: Get started with ArcGIS Pro Common skills for working with data in ArcGIS Pro
