X-Ray is amazing if you have not used it for your Desktop Maps... you are missing out. Anyways my idea is a tool like 'X-Ray for ArcMap', which analyzes the cartographic contents of all the maps and services you have placed on an ArcGIS Online Map/App. I want to be able to follow the lineage chain of data from the App to the Map to the Server to the MXD and see where cartographic changes or manipulations were made on the dataset. (Ex: Max viewing scale or Transparencies.) ... View more

I was wondering if anyone has come up with a way to link enclosed documents and pictures back to the Shapefile or Feature Class as a Hyperlink (or some other form)? This question came about when I did not want to have to deal with Broken links after Hyperlinking Files to my Shapefile... If I moved the Files or the Shapefile... the Links would break. This made Data Management of the Organization a Pain. ... View more

I need a code which essentially... "The terrain ruggedness index (TRI) is a measurement developed by Riley, et al. (1999) to express the amount of elevation difference between adjacent cells of a digital elevation grid. The process essentially calculates the difference in elevation values from a center cell and the eight cells immediately surrounding it. Then it squares each of the eight elevation difference values to make them all positive and averages the squares. The terrain ruggedness index is then derived by taking the square root of this average, and corresponds to average elevation change between any point on a grid and it???s surrounding area." All I could figure out was.... ssdiff = ( ( sqr ( "in_elev"(0,0) - "in_elev"(-1,-1) ) ) + ( sqr ( "in_elev"(0,0) - "in_elev"(0,-1) ) ) + ( sqr ( "in_elev"(0,0) - "in_elev"(1,-1) ) ) + ( sqr ( "in_elev"(0,0) - "in_elev"(1,0) ) ) + ( sqr ( "in_elev"(0,0) - "in_elev"(1,1) ) ) + ( sqr ( "in_elev"(0,0) - "in_elev"(0,1) ) ) + ( sqr ( "in_elev"(0,0) - "in_elev"(-1,1) ) ) + ( sqr ( "in_elev"(0,0) - "in_elev"(-1,0) ) ) ) But how do I even try and translate it onto Python and into ArcMap. I have never tried to breach the ArcMap/Python boundary. Please HELP! Thanks, Rachel ... View more
