Recommended Posts

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.

Thank you

I never use feature extraction, since sometimes the result is unpredictable  :shocked:

Using script , you can make your own feature extraction

see this paper

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:

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.
