Dear Arthur Thank you for your efforts, I have done all you instructed, unfortunately still we don't any feature classe like polygon, so how can we input to the Polygon to Raster window? If you mean first create polygon feature around building, second Input this polygon in the Polygon to Raster window the output is not like something we want, it is similar to the manually digitizing, what we focusing on exactly is generating building outline automatically (including segmentation,classification, cleaning up, converting to polygon). ...

Dear Dan Thank you for pursuing me in this issue, my supervisor suggested to perform linemap using automatic feature extraction instead of manually digitizing, because he believed that manually digitizing could't be able to digitize exact pixel which represents an edge, I think if I solved RGB to Grayscale problem output result would be more satisfactory. last link not solved may problem. ...

Dear Dan I have done all steps that was Dareen said such as filtering, segmentation, classification, cleaning up, ...etc, also I have generated CAD format vector file (as you see in the screen shot), as you see there are many unlike features need to be eliminated! unfortunately I could't be able to eliminating, therefor I tried to perform filtering again, still I have a problem converting from RGB to Grayscale. ...

Dear Arthur Thank you for, actually your link is very useful, I have performed low-class filter before segmentation and classification, unfortunately RGB raster will converting to the Grayscale (as you see in the attached screen shots), could you please clarify how can I keep RGB after filtering? ...

Dear Cody I have performed high-pass filter successfully (as you see in screenshot), after high-pass I have performed raster to polyline/polygon conversion unfortunately no line clear in the output, therefore, could you please instruct me how can I perform edge detection in Arc Map or python? as I understanded from internet searching about edge detection is mostly using python, actually I don't have any knowledge about python. ...

Dear Dan I have performed High-pass filter, related to the mask I have used same raster file which is needed to perform filter on it, high-pass done successfully but converted to the grayscale (as you see in the screenshot). Currently I got edge enhancement, how can wI perform edge detection (i.e which tool can do edge detection?)       ... View more

Dear Dan I have arranged as you mentioned, unfortunately again failed same error message appeared. ... View more

Dear Darren I as a civil engineer GIS field is new and too much hard/complex for me, therefore applogize if disturbed you, I have tried many time to do the Low-Pass filter, unfortunately all trials are failed (as you see in screenshots), could you please clarify briefly how can I do smoothing (low-pass)->edge detecting (Laplacian).    ...

Dear Dareen Still I am waiting your recommendation about extracting ONLY edges of features. ... View more

Dear Cody Still Iam waiting your recommendation based on the posted screenshot. ... View more

Cody What I am looking to display on the line map is ONLY edges/corners of features like manmade features (House, road, manhole, yard, ...etc as you see in the screen shoot ... View more

Darren Okey I will reclassify using Arc Map, let me know how can I do? What I want to export to vector is only edges/corners of  features (like playing yard, house, road, walkway, etc) as you see in the screenshot sketch. ... View more

I have classified generated DSM for DTM extraction using Pix4D software, is it possible to utilize this classification instead of reclassification by Arc Map? ... View more
