Okay, once you downloaded the multidimeonsional tool zip and unzip it, open the folder and there is an netCDF4-1.0.4.win32-py2.7.exe.  That is the installer for the netcdf python module.  Let it run and it will install the netcdf python module on your computer.  ... View more

I took her response to mean she opened the toolbox in the catalog, but once she tried to put in the URL parameter, it said it was invalid, so the red x showed up next to the parameter.  The tool had no syntax errors when I tried it, I suppose she needs to be sure that the netcdf python module is installed. ...

This is a truncated part of the script, and the part that I think is the issue class Dap2tin(object):     def __init__(self):         """Define the tool (tool name is the name of the class)."""         self.label = "Dap2tin"         self.description = "Access data from the FVCOM Ocean Model via DAP and return a TIN"         self.canRunInBackground = False         self.url = None         self.dataset = None         self.cols = {             'url': 0,             'dataset_var': 1,             'iyear': 2,             'imonth': 3,             'iday': 4,             'ihour': 5,             'klev': 6,             'sr' : 7,             'out_tin': 8         }         self.default_urls = ['http://www.smast.umassd.edu:8080/thredds/dodsc/fvcom/hindcasts/30yr_gom3/mean',         'http://www.smast.umassd.edu:8080/thredds/dodsc/fvcom/hindcasts/wave_gom3',         'http://www.smast.umassd.edu:8080/thredds/dodsc/fvcom/archives/necofs_gom3',         'http://www.smast.umassd.edu:8080/thredds/dodsc/fvcom/archives/necofs_mb',         'http://www.smast.umassd.edu:8080/thredds/dodsC/FVCOM/NECOFS/Forecasts/NECOFS_GOM3_FORECAST.nc',         'http://www.smast.umassd.edu:8080/thredds/dodsc/fvcom/necofs/forecasts/necofs_fvcom_ocean_massbay_forecast.nc']     def getParameterInfo(self):         """Define parameter definitions"""         # Parameter: URL         url = arcpy.Parameter(             displayName="OPeNDAP URL",             name="url",             datatype="String",             parameterType="Required",             direction="Input")         # set default value to 30 year hindcast monthly mean dataset         url.value = 'http://www.smast.umassd.edu:8080/thredds/dodsC/fvcom/hindcasts/30yr_gom3/mean'         url.filter.type = "ValueList"         url.filter.list = self.default_urls I dug into that python toolbox and the issue seems to be with the url parameter, it only accepts web addresses that are defaulted in that list.  If you could add your url to the list, then it could try to process.  I don't have time to try and fix it and upload a new toolbox with script tool. Filip Král​, you able to help on this? Also, Curtis Price​, you name is on the credits for a few of those other tools, for helping with them.  You got any suggestions or comments that can help out? ... View more

From what you said, I believe you are overthinking this too much.  You have a shapefile with a certain field in it with 3 different values.  You want to make a new feature class for each based on the field value, either "rs", "bs" or "brn".  Why not do a select by attribute for each one of those values, then make a feature layer then convert the feature layer to a feature class? ...

There is no way to export out georeferenced maps from layout view. To quote the ESRI help: "To add georeferencing information, check Write World File. This option is only available when you export while in data view and creates a world file that contains information that is used in conjunction with the exported raster file to tell software where the image is located in the world. The file will have the same name as the image file and a file extension that is based on the first and last letters of the image's file extension plus the letter w. (For example, if you create a TIFF image named MyMap.tif, the world file is called MyMap.tfw.)" ... View more

Depending on the shape and dimensions, this could be a very easy or a difficult task.  Could you give a little more detail about what you are wanting to do or possible give a screenshot of your polygon? ... View more

There have been quite a few people lately with the exact same question about doing this.  Near has been the answer everytime, wonder why this seems to be a consistent question from the community? ... View more

What exactly is the error code it is throwing? I would guess you are having an issue with your query statement, check this post Python - Select by attributes query issue.  Joshua Bixby shows a great example of using python string formatting for query statements.  You are using string formatting in your code, so it should be simple to adapt it for your query statement. Hope this helps ... View more

It would depend on what the variable outFld contains.  If it contains a list of fields of which "Area" is the 4th field in the list, then yes you would use row[3].  However, if it only contained a single field, "Area", then you would use row[0].  Generally it is good practice to only put the fields into a cursor that you will actually be using to check or update data, since it will run faster if it needs values from 1-2 fields then from 20. ...

I'm still just a student and haven't been able to look into Open Source GIS a whole lot, though it sounds like it would be fairly easy to do in QGIS, more so then running a tool like that in batch mode in ArcGIS.  Python just helps augment ArcGIS geoprocessing tools to make them more effective.  ...

Lisa, programming isn't required to do this for a single  tif, but it sounds like she wants to convert an entire folders worth of tifs to jpegs.  It fine to go and do manually if you have just a few, but it sound like they could have many tifs to be converted, so a script to do it all could save lots of time.  ...
