Hi I've got a small script that I've turned into an ArcToolbox tool / script / thingy. I would like to be able to pass ArcMap layers to the tool (ie drag the layer directly from ToC into the tool, and have the tool run only on the selected features). By and large, I have this running the way I would expect. However, if I'm trying to pass a layer to the tool that has been renamed in the ToC (ie given a 'proper' name rather than just the feature class name) the tool fails. For reference, I'm using arcpy.GetParameterAsText to pass variables from the tool to the script, and the particular parameter that is causing issues is a type 'Feature Layer' and is a multivalue parameter. Does anyone have any crazy suggestions that may fix this issue? I'm out of my depth! Thanks ... View more

Hi - I'm unsure whether this is a Python question or a geoprocessing question. I'll post it here and see how we go. I am trying to use the 'warp' function in a rather novel way. I have a heap of (~800) individual QR codes, which I'd like to georeference so that they can be displayed as map features. The QR codes are all the same size and I can use the same reference points, whereas the location to georeference the features 'to' (ie where I want them to sit on the map) will change from code to code. This location is determined by the location of a given point. I've cobbled together a script to iterate through the codes, and the script runs correctly, but the output features aren't georeferenced at all. I've also tried georeferencing a single feature via the Toolbox, but that doesn't perform as expected either. The script (snippet of) I'm using is below: ls_inputs = os.listdir(ws_inputs) for i in ls_inputs:     if i[0:-4] in dict_mapcentroid:         print "Working on", i         input = os.path.join(ws_inputs, i)         cent_x = dict_mapcentroid[i[0:-4]][0]         cent_y = dict_mapcentroid[i[0:-4]][1]         target_pt = "'11.5 -158.5';'158.5 -11.5'"         source_pt = "'%s %s';'%s %s'" % (cent_x - 1750, cent_y - 1750, cent_x + 1750, cent_y + 1750)         output = os.path.join(ws_outputs, "georef_%s" % i)         arcpy.Warp_management(input, source_pt, target_pt, output, "POLYORDER1")     else:         print "Fail on", i (dict_mapcentroid refers to a dictionary with the feature name as key, and the coordinates of the centroid as a [x,y] list) (the reference points are bottom left and top right, the +/- 1750 allow for the scaling of the feature to appear 3 x 3cm at 1:250K) Can anyone shed any light on why this wouldn't be working - or am I simply trying to use a tool in a manner in which it was not intended?

Hi I've got an interesting project that I'm going to start working on next week, and I'm not quite sure how to tackle it. I need to make a series of overview maps with an overlay of the map extents of my topographic map library. This in itself is easy enough to do. The catch is, I would like to label each extent / tile feature with a QR barcode, which will be available as as an image. I know I can use pictures as label features - however there are several hundred map extent features and I don't want to label them all individually! What are my options for using the QR codes as labels? The two options I can immediately think of (but are untested) is either to load the QR code into my map tile FC as a BLOB feature, or include a file path to the QR code. Does anyone have any bright ideas? Thanks! ... View more
