In your case (jpg rasters and exact same extent for all rasters) the Warp From File tool is just fine. If you haven't saved a link file yet you should do this first: Georeference one raster in ArcMap, click the View Link Table button and save the links to a text file using the Save button: Then there are different options: Batch: You can use the Warp ...

Erase is the tool for this in ArcGIS. http://resources.arcgis.com/en/help/main/10.1/index.html#//00080000000m000000 Kind of like an "opposite clip" You need a higher level license to do this.

A MultiLineString is a list of lines: from shapely.geometry import MultiLineString, mapping, shape coords = [((0, 0), (1, 1)), ((-1, 0), (1, 0))] lines = MultiLineString(coords) print lines MULTILINESTRING ((0 0, 1 1), (-1 0, 1 0)) for line in lines: print line LINESTRING (0 0, 1 1) LINESTRING (-1 0, 1 0) # convert to GeoJSON format: print ...

The ArcGIS Erase tool will work, but as user two seven three nine says, you have to have the required license level to use it. The Xtools Pro extension suite has an Erase tool built in that will do the same thing and is free. Some of the features of Xtools require that you buy a license after the 14-day evaluation period is over, but the Erase tool (and a ...

Those are actually two different things. Geoprocessing tools don't honor the split policies of feature classes or tables as noted on most of help pages for the tools - this one for example (look for the yellow triangle exclamation point). Those are the policies set using domains, and where that third option of Default comes in. As far as I know, this ...

There's another option that isn't as elegant as Erase or Union and involves a few more steps, but it can be done at Basic and without third party tools (which can be an issue if you don't have administrative rights on the machine). Make a copy of your buffer layer, bufferdummy. If you have more than one layer, you can select them all and export/copy them ...

If you don't have an info level of license you can do it using union, which is limited to two feature classes in basic and standard, but that's enough. Union your two layers, to keep it simple join the attributes with FID only, and then delete the ones that have a FID value from the second feature class. There are a few ways to delete but if you wish to do ...

I'm only addressing the "How does one take a text string, and pass it off as a text expression?" part here but try using Python string formatting as below: RC1 = str(BotVal) RC2 = str(MegaCount - 1) NODATA = "NODATA" RC3 = str(MegaCount) RC4 = str(TopVal) Val = "1" Qu = "" Equ = "{0} {1} {2}; {3} {4} {5} {6}".format(RC1,RC2,NODATA,RC3,RC4,Val,Qu) print Equ ...

I've come across DataMatch by Data Ladder, which is an excellent fuzzy matching and address standardization/address parsing tool used across business and would work really well for this situation. They offer a complimentary trial for new users. In face, an independent verified evaluation was done of the software comparing it to major software tools by IBM ...

One challenge faced by address verification services is that some addresses are valid, yet not deliverable by USPS. I live in a small town in which USPS provides no home delivery; all residents must use PO boxes. However, both UPS and FedEx do provide delivery to our homes, so clearly our addresses mean something. ;-) Anyhow, the SmartyStreets ...

Since the version 2.x, PyQGIS has an has an interpolate function similar to that of Shapely : for distance in xrange(0,lenght_line,20): point = line.interpolate(distance)
