Ever wanted a quick and easy way to design visually pleasing cross sections? Streetmix allows you to do just that. You can specify a right-of-way width and add travel lanes, bike lanes, sidewalks and medians as you see fit. Here is an example output:
Are you tired of hunting for a projection when creating feature datasets or reprojecting data in ArcGIS? Well you don’t have to hunt. Just copy the .prj file from the subfolder in the Projected Coordinate Systems folder (C:\Program Files (x86)\ArcGIS\Desktop10.0\Coordinate Systems\Projected Coordinate Systems) and place it in Coordinate Systems folder (C:\Program Files (x86)\ArcGIS\Desktop10.0\Coordinate Systems).
Now when you are prompted to select a coordinate system you do not need to hunt for it, it is available immediately in the first dialog. Store copies of all of your “favorite” projections here and it will save you a lot of time in the long run.
