mostafa Posted October 11, 2011 Report Share Posted October 11, 2011 Hi all, i am working with a big raster data sets, and i am using manually digitize in arcgis, so its consume my time, so can any one tell me what is the best tool that can make simi or full auto feature extraction, like roads and buildings, i know Imagine Objective in ERDAS Imagine, if any one tried it with him self, tells me about his experience as possible.

Lurker Posted October 11, 2011 Report Share Posted October 11, 2011 I never use feature extraction, since sometimes the result is unpredictable :shocked: Using script , you can make your own feature extraction see this paper [hide] http://proceedings.esri.com/library/userconf/proc05/papers/pap2109.pdf [/hide] I know many software special for feature extraction, they claim to be the best , I dunno, since I dont have opportunities to test it :laugh: this is for the example [hide] http://www.overwatch.com/products/feature_analyst.php [/hide] sound promising heh, I don't know is there any different result between using our standart GIS software and this specific feature extraction software regards, :cry: Quote Link to comment Share on other sites More sharing options...
mostafa Posted October 11, 2011 Author Report Share Posted October 11, 2011 thank you Lurker, i know products of Overwatch ink but this products have not any medicine on the internet, any way, i think it is a big deal with raster image if any one use auto feature extraction specially high resolution of raster, i did manually digitized by arcgis, so i know the importance of the time, when you want to finish your task,early.
