Thanks Dan, That was the first thing i looked at. It wont let me change any of my parameters to optional. I think it may be because other processes rely on them (the part where it erases the input features from the buffer). However, if the above was true and it was because other processes relied on the inputs, i would think that i would be able to set the polyline stream/river input to optional because it has no other processes relying on it. (didnt need to set up erase process since it was a polyline layer) Any other ideas?

I have a model that takes three inputs (waterbodies, streams/river polyline, and streams/rivers polygon). It takes each one of these inputs, buffers them, merges all three buffer outputs to a single layer, and then deletes the area of the input features leaving only the buffer area. Id like to make it so that this model could still be run if the user decided to only input two out of the three layers because there just so happens to be no waterbodies in the focus area. I'm having a bit of trouble figuring out if this is possible in modelbuilder. I could likely easily accomplish this in python but first wanted to check here to see if anyone had any ideas. Thanks! Ben

How are you sure that the flow direction pattern you are seeing for the salt flats isn't correct?

I'm not entirely sure that the flow direction grid is incorrect. The way the salt flats are represented look very similar to how a water body would be represented, which makes sense. A lot of what was within the salt flats may have been filled in as a depression. Also, i would look at the year the DEM was created vs the year the imagery was created. It looks like there is some sort of levee or road through the salt marsh that i'm not seeing in the aerial imagery. Can i get a long/lat for the location of this image.

I don't think you would need to use an iterator for this. Set up your model so that from your dataset you have three different "select by attribute" branches, one for each value. Follow these three up with "Make Feature Layer' and from there you should be able to achieve what you described. The model would require 1 input parameter and 3 outputs.

Just taking a stab here. It's possible this is incorrect, i'm not familiar with using a arcpy.polygon as an output. Is it possible you are overwriting your output with each iteration rather than adding to it? Wouldn't you need the output of the first iteration to become the input of the second and so on.. to me it doesnt look like this is happening. Again, i could be wrong. Ben

With editing enabled try clicking on the "Edit Button" located between "Add" and "Basemap". This should bring up a screen allowing you to add data points. While this screen is active you should be able to relocate existing points.

Well, that's a bummer. Any alternative solutions on how to included a graph on a Story Map Swiper? (i dont wanna mess with the code if i don't have to) The goal of this swiper project is to swipe between two imageries, one a the beginning of a drought and one at its peak. The graphs accompanying it show that pollutant levels increase as water level decreases due to drought. Right now the only alternative i can think of is including a dummy shapefile with two points next to my waterbody, and customizing the symbology for those points to be a white box with TP inside (Total Phosphorus), and a white box with TN inside (Total Nitrogen). Ideally one would be able to click theses boxs and the graph would be in the pop-up. This solutions seems a bit unintuitive to a user, and im not 100% sure i can customize symbology yet =(

I'm in the process of building a Story Map Swiper and i'm trying to find a way to include a few graphs in the map but cant seem to figure out how. I'm not using a series, its only 1 location included in the swiper. By looking in the gallery section i can see that others have included images in the description section of the map but i cant figure out how to do this. Here is an example of Swiper map with images in the description section http://lra-cha.maps.arcgis.com/apps/StorytellingSwipe/index.html?appid=716b6277db404a5aaf2406f7bb444295&webmap=605e5f82e… Any help would be appreciated. Thanks, Benjamin MIttler

You may have looked at this already but the ESRI help page on "Trace Geometric Network" specifically mentions some tips for using it in modelbuilder. ArcGIS Help 10.1

Thanks Kevin, worked like a charm. I actually came across the thread with this information while researching the problem and it ended up that i was just calling it wrong. For all others running into this error in the future this seems to be the workaround.

Todd, Google Earth, the file actually opens when my addin is run, it just crashes arcmap in the process of doing so. Thanks, Ben

Hi All, I'm currently attempting to develop an addin that creates a KML from a layer within arcmap, and then opens that KML. All seems to be going well except that every time the tool runs it crashes arcmap. I am aware that this is because i am using the "os.startfile()" command. What possible workaround can i use to get this file to open at the end of my script. Thanks, Ben *Not a python expert by any means

Well that is certainly unfortunate. Looks like i'll have to code in to turn off those two fields before exporting.

Hello All, I have written a script that takes an input,runs a couple of geoprocesses, exports to an excel sheet, and then runs a couple of manipulations on the excel sheet. I have tried to make it so that by the time you are at the stage where your excel spreadsheet has been created the spreadsheet fields will always look the same no matter how many fields in the input. This allows me to easily manipulate the excel spreadsheet. The one problem i am running into involves my dissolve step. I have it set up so that Dissolve is run on two fields. When my input is a shapefile and dissolve is run the output is a shapefile with those 2 fields. However, if my input is a gdb layer my output will contain those 2 fields with the addition of the Shape_Area / Shape_Length Fields. Does anyone know why Shape_Area / Shape_Length are automatically added when using a gdb but not when using a shapefile? Thanks, Ben
