Let’s face it: being a geoscientist and writing code goes hand in hand in recent times. Most programs have their own code editor like MatLab with its m-file generator or R with its handy version of RStudio. But when it comes to webmapping and direct code writing in an open environment you are mostly sticked to a certain editor which has some syntax higlighting and maybe a syntax checker like Notepad++, kate or textwrangler.

Using the topology tools in ArcGIS makes this much easier as it treats your shared vertexes as one vertex and adjust the geometry of both polygons… “Thumbs Up!” for that!

Editing in ArcGIS can be hell of a work. In this video I show some advanced and maybe useful tools in the editor toolbar which might improve your everyday work… If you don’t know how to do the simple stuff, stick with this one by reading more:
