Why Firefly<\/a>? The Firefly imagery basemap is an interesting option for any application where imagery is required for valuable landcover\/topographic context but also needs to recede into the background to best play a supporting role to the thematic layers that live atop. Like this app<\/a>. And as you zoom in, and need more specific geographic context that color provides, the basemap gradually returns to full-color.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":238732,"id":238732,"title":"1","filename":"1-1.jpg","filesize":242765,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/06\/1-1.jpg","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-living-atlas\/imagery\/firefly-basemap-imagery-launched\/1-4","alt":"","author":"6971","description":"","caption":"","name":"1-4","status":"inherit","uploaded_to":238682,"date":"2018-06-15

Those of us that know it best think about it often. I swear...the maps I've seen. Sometimes it gives me pause, though, Firefly being free, belonging to every cartographer who wants to take a chance. I have to remind myself that some map styles aren't meant to be caged. Their radiance is just too bright. And the part of me that knows it was a sin to keep it to myself does rejoice<\/a>.\n\nSo here it is<\/a>. Do interesting things with your data.\n\nThe Firefly style<\/a> consists of the following point, line, and polygon symbols, packaged up for your adventures in ArcGIS Pro...\n\n![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/FireflyStyle.png\")
<\/a>\n\nThere are 20 pre-defined colors available for each symbol (but there is no reason you can't tweak them for whatever visualization scheme you cook up). Here is a reference of their numbering...\n\n![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/ColorWheel.png\")
<\/a>\n\nTo add these to your Pro project, first download the Firefly.stylx<\/a> file and save it to your machine. From your project's Catalog panel, right-click the Styles<\/a> category and choose to add a style<\/em>.\n\n![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/AddStyle.png\")
<\/a>\n\nPoint it to your Firefly.stylx file and you are good to go. Thereafter, the firefly styles will be available in the project via the Symbology panel's Gallery.\n\n![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/SymbolGallery.png\")
<\/a>\n\nSo many possibilities. But where to start?\nPoints<\/h2>\nHere's a look at the standard Firefly point symbol, in this case showing, obviously, Taco Bell locations scaled by revenue...\n\n
![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/Firefly.jpg\")
<\/a>\n\nBut sometimes you want to turn your Firefly point features up to eleven. I've got you covered. There is an alternative version with a twinkly lens flare shimmer sort of thing going on. Like in this map of luminescent earthquakes...\n\n![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/FireflyShimmer.jpg\"){kind=spacer}
<\/a>\nLines<\/h2>\nFirefly has two line styles. But, again, you can totally play with the Symbol settings to teach it whatever tricks you need. Here is the standard, solid, line illustrated in this map of glowtastic graticules...\n\n
![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/FireflyLine.jpg\")
<\/a>\n\nBut sometimes you just need a dashed line. So here is an example of the dashed Firefly line style applied to contour lines in the Pacific Northwest...\n\n![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/FireflyLineDash.jpg\")
<\/a>\nPolygons<\/h2>\nHere is a look at the Firefly polygon style. It is a glowing boundary with a faint fill, applied to these Mediterranean bathymetric zones, submitted for your approval...\n\n
![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/FireflyPoly.jpg\")
<\/a>\n\nBut when you have adjacent polygons, which is often the case with human geography data, the glowing edges of the Firefly polygons can bleed into, or overlap, each other and sort of make a mess. So here is an alternate version of the polygon fill with only an inner<\/em> glow, as evidenced by these hexbins of aggregated Chipotle locations...\n\n![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/FireflyPolyInner.jpg\")
<\/a>\nBasemaps<\/h2>\nAh, basemaps. When it comes to Firefly cartography, the basemap is a big player. A firefly basemap ought to be dark and nearly devoid of color. Conveniently, we have a Firefly global image service<\/a> that you can use as a basemap. If that's too busy, then I recommend Dark Gray Canvas vector tiles as an alternate.\n
Thematics<\/h2>\nJust because there is a spectral set of colors available, please don't use all of them in a thematic map. The rainbow color scheme has lots of problems<\/a> for perception in scientific visualizations. I recommend using up to 6<\/strong> consecutive firefly colors if you are putting together a classed thematic map. Any more than that and you start to span into another dominant hue and perception diminishes.\n\n
![\"\"](\"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2018\/03\/ColorThematic.jpg\")
<\/a>\n\nIf you need contrasting colors, the colors opposite each other on this wheel tend to be differentiated well. Of course be careful<\/a> to avoid colors that are particularly problematic for those with color-deficient vision.\nNo Color<\/h2>\nDon't want a color but still want a glowy Firefly map? No worries; there is a non-colorized version of each symbol, just look at this map of top college football prospects, scaled by player size...\n\n
