When changing point symbols, you’ll find many different ones to choose from organized in categories. In addition to these symbols, you can use any hosted image as a custom symbol.
Using an existing image
To use an image as a custom symbol, follow these steps.
Step 1 – Locate the hosted symbol you want to use, and copy the URL. The symbol must be at a URL location, and should point directly to the source image (and not an image viewer). For best results use a square PNG, GIF, or JPG file 120 x 120 pixels or less. Larger images will be adjusted to fit.
Tip: use a PNG or GIF with a transparent background if your symbol does not fill the square to avoid unwanted white space.
In this example, the following custom symbol will be used. Click the image to view it, and copy the URL.
Step 2 – In Change Style, select any category.
Step 3 – Click Use an Image. In the input box paste the URL obtained in Step 1 above.
Step 4 – Click the add button (white...

So without further adieu……

- To register there will be a deposit of $125 dollars. If I cancel the class the $125 is refunded and if you cancel the $125 isn’t refunded.
- Classes will be in Chattanooga TN. I’m arranging the space now.
- I am going to be picky on who attends. I want this to be a good experience so it’s up to me to weed out the people who are not going to make this a good experience.
- Classes are going up to $375 a person per day.
- I am going to put some more effort into attending conferences and teaching this class. I taught this last at FOSS4GNA 2016 and it was a really...
Uncharted Atlas is a Twitter bot that generates a new fantasy map every hour. The brainchild of glaciologist Martin O’Leary, it uses algorithmically created terrain that is weathered by water erosion, a process he details on this page (All Over the Map’s post explains it in more human-readable terms). As Martin writes:
I wanted to make maps that look like something you’d find at the back of one of the cheap paperback fantasy novels of my youth. I always had a fascination with these imagined worlds, which were often...
