I have been involved in a project requiring a significant amount of GIS editing. As part of this process I have evaluated the most reliable and efficient tools for polygon editing. My basic requirements were: snapping to vertices during add/split Easy to move around/zoom in/out/pan while editing reliable Fortunately, I was able to assess the process across most GIS packages, and this how they fared: MapInfo - Editing is quite laborious, involving several steps for .....

Well according to the ESRI: "When ArcMap prints or exports to any format, an EMF file is created. Windows attempts to allocate enough memory to read the entire EMF metafile.

The early days saw the reliance on client based plugins and has slowly progressed to no reliance on client side plugins and virtually no reliance on server side solutions. The Past My first attempt at a webGIS was a custom built solution rendering maps in SVG which essentially served as a stepping stone until a reliable c.....
