I have a project to do and at the moment i have 2 tif images and their geografic data(longitude latitude) of their upper left pixel.What i want to do is get the common geografic place of the 2 images...so i want to get lonitude,latitude so that i can only keep the parts of the images that show the same geografic place.  The 2 images show deferent information for that place...for example the first one i a simple image and the second one shows the humidity level. I want first to find the common place for each picture so that later i make the pictures to have the same width and length so that i can go back and forth on these 2 pictures looking at the same place but different information.  So, is my idea of finding the common place by each pixel'l geodata a good idea?   if yes...how would i do that?  if no...how should i do it?
I have a set of aerial images which I am trying to clip by their overlapping areas, for use in a more involved program I am writing.  Is there a command line based tool out there with an easy method for extracting the overlapping areas from a pair of images?  The images themselves do not have georeferencing, but they DO come with a shapefile containing bounding boxes of the image collects, as well as IMU data from image collection.  I know this may be difficult since the images will have slight perspective differences, but I was hoping it would still be possible--especially since I am trying to maintain and utilize these perspective differences for something else.
Launch iOS app from sites Can we add functionality to the mobile site to view the page in the SE iOS app? It could be through  or a link at the bottom where the download link is.        I really don't care which, but right now there's just no way to do it. I would like to say something like     The boy, Adam's, favorite toy was a bike.   What is the proper way to say this? Simulation of interacting particles I loved the keyboard shortcuts in Windows 7 (i.e. Win + &larr; moves a window to the left side of the screen), but I'm not sure on what some of the new ones might be for Windows 8.  What are all of the NEW keyboard shortcuts that I can use while working in Windows 8? Compactness of  Multiplication Operator on $L^2$ I'm playing around, trying to write some code to use the  APIs to shorten a URL.  After reading , I tried:     TRIM_API_URL = 'http://api.tr.im/api'    auth_handler = urllib2.HTTPBasicAuthHandler()    auth_handler.add_password(realm='tr.im',                              uri=TRIM_API_URL,                              user=USERNAME,                              passwd=PASSWORD)    opener = urllib2.build_opener(auth_handler)    urllib2.install_opener(opener)    response = urllib2.urlopen('%s/trim_simple?url=%s'                               % (TRIM_API_URL, url_to_trim))    url = response.read().strip()   response.code is 200 (I think it should be 202).  url is valid, but the basic HTTP authentication doesn't seem to have worked, because the shortened URL isn't in my list of URLs (at ).  After reading  I also tried:     TRIM_API_URL = 'api.tr.im/api'    password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()    password_mgr.add_password(None, TRIM_API_URL, USERNAME, PASSWORD)    auth_handler = urllib2.HTTPBasicAuthHandler(password_mgr)    opener = urllib2.build_opener(auth_handler)    urllib2.install_opener(opener)    response = urllib2.urlopen('http://%s/trim_simple?url=%s'                               % (TRIM_API_URL, url_to_trim))    url = response.read().strip()   But I get the same results.  (response.code is 200 and url is valid, but not recorded in my account at .)  If I use query string parameters instead of basic HTTP authentication, like this:     TRIM_API_URL = 'http://api.tr.im/api'    response = urllib2.urlopen('%s/trim_simple?url=%s&amp;username=%s&amp;password=%s'                               % (TRIM_API_URL,                                  url_to_trim,                                  USERNAME,                                  PASSWORD))    url = response.read().strip()   ...then not only is url valid but it's recorded in my tr.im account. (Though response.code is still 200.)  There must be something wrong with my code though (and not tr.im's API), because  $ curl -u yacitus:xxxx http://api.tr.im/api/trim_url.json?url=http://www.google.co.uk   ...returns:  {"trimpath":"hfhb","reference":"nH45bftZDWOX0QpVojeDbOvPDnaRaJ","trimmed":"11\/03\/2009","destination":"http:\/\/www.google.co.uk\/","trim_path":"hfhb","domain":"google.co.uk","url":"http:\/\/tr.im\/hfhb","visits":0,"status":{"result":"OK","code":"200","message":"tr.im URL Added."},"date_time":"2009-03-11T10:15:35-04:00"}   ...and the URL does appear in my list of URLs on .  And if I run:  $ curl -u yacitus:xxxx http://api.tr.im/api/trim_url.json?url=http://www.google.co.uk   ...again, I get:  {"trimpath":"hfhb","reference":"nH45bftZDWOX0QpVojeDbOvPDnaRaJ","trimmed":"11\/03\/2009","destination":"http:\/\/www.google.co.uk\/","trim_path":"hfhb","domain":"google.co.uk","url":"http:\/\/tr.im\/hfhb","visits":0,"status":{"result":"OK","code":"201","message":"tr.im URL Already Created [yacitus]."},"date_time":"2009-03-11T10:15:35-04:00"}   Note code is 201, and message is "tr.im URL Already Created [yacitus]."  I must not be doing the basic HTTP authentication correctly (in either attempt).  Can you spot my problem?  Perhaps I should look and see what's being sent over the wire?  I've never done that before.  Are there Python APIs I can use (perhaps in pdb)?  Or is there another tool (preferably for Mac OS X) I can use? I submitted a new version of the sitemap index for my site in Google Search Console two days ago. Soon after submission, GSC started saying that the index was "processed successfully", and yet has continued to display zero as the number of discovered URLs.  Note that my sitemap index points to about 11000 sitemaps, which provide actual links to pages.  I'm pretty sure the format of both the sitemap index and the individual sitemaps is correct.  Screenshot:    Should I worry about this? What does it mean?  Edit on 2020-02-03:  Google finally started displaying the right number in Total discovered URLs. It must have happened sometime in January. Why so late - I have no idea... Converting string of 1s and 0s into binary value I'm trying to convert an incoming sting of 1s and 0s from stdin into their respective binary values (where a string such as "11110111" would be converted to 0xF7). This seems pretty trivial but I don't want to reinvent the wheel so I'm wondering if there's anything in the C/C++ standard libs that can already perform such an operation? What's this =! operator? Why do we say "is it" when asking a question rather than "it is"? What it says on the tin, a foreign friend of mine has asked and I can't tell him; apart from it sounding horrible.  For example:  "Why is it raining today?"   Instead of:  "Why it is raining today?" WPF Get Element(s) under mouse For which values $r, s \in \mathbb R$ is the set $\{u, v, w\}$ linearly independent? How to normalize data to 0-1 range? I am lost in normalizing, could anyone guide me please.  I have a minimum and maximum values, say -23.89 and 7.54990767, respectively.  If I get a value of 5.6878 how can I scale this value on a scale of 0 to 1. What would be a good term for continuous testing post-deployment? At what port did Lorance Effler born about 1787 in Germany come to the US? Which of these sentences is correct, and why?   "What if the Moon was a Disco ball?" or  "What if the Moon were a Disco ball?"
