Can you try running the Surface Contour Tool again, but this time up the field precision?  The default precision value for the field if you don't change it is 0, which means it return an integer, not a float.  ArcGIS handles the values by truncation, not rounding.  I still believe this is a precision issue, so if you could please run the tool again with the field precision changed, I think we would get the correct values. ...

I wonder if the issue is that you made your contour interval to be .914.  While it is technically 3ft, it will still populate the attribute table contour values based on the contour interval(.914).  So depending on how many significant digits are showing, it might show a 0 for the contour elevation, even if it is 0.914(m) or 3ft.  For 6ft it might show 1 based on the number of significant digits showing for the field.  If your contour field is still storing elevation in meters, I'd make a new field and then multiply your first contour field by 3.28084 to have it storing the values in feet in the new field. Mind posting a screenshot of the attribute table? ... View more

When I use the Contour Tool (Spatial Analyst) it creates the field Contour populated with the elevation of each contour.  None of mine are near a shore line, but the minimum value is ~1350.  I believe the values in your field are the actual elevation values of the contour. In Surface Contour, there is a parameter to which you can assign the contour value to a field name, I believe if you don't name a field name for it to create then it makes the "Contour" field and populates it with the contour elevation. Also shorelines are highly variable depending on time of day in aerial imagery due to tides, so it would be expected for there to be some margin of error with the contours lining up with the "shoreline" ...

It under the Windows >Image Analysis, you can change the layer properties.  I haven't tried myself since I don't have any LANDSAT handy, but figured it could point you in the right direction.  I think the help the others have posted will be better for you anyway.  If you are on ArcGIS 10, I'm not sure they had the Image Analysis Window it might be 10.1 and up. ...

You would make a list of the feature class you want to clip with and leave the input the same for the 1 feature class you want clipped.  You would then loop through each of the feature classes you want to clip with and use each individual one as the clipping layer for the tool.  Your input would stay the same each time. ...

I reworked a bit of an old script I had, but this should be close to what you need (Untested). The original post that is based off of is here if you need more refernece.  https://community.esri.com/thread/107816 import arcpy  import os  workspace = r"workspacepath"  out_mdb = r"filepathtomdbhere" for dirpath, dirnames, filenames in arcpy.da.Walk(workspace,datatype="FeatureClass"):      for filename in filenames:            arcpy.CopyFeatures_management(os.path.join(dirpath , filename) , os.path.join(out_mdb , filename.strip(".shp"))) ...

Also make sure you are naming out of your output features a unique name, otherwise it will either crash or overwrite the features you are creating. If you have a relatively small number of features, it might be easier to run clip in batch mode rather than write out a script.  As long as you set parameters that stay the same before you add new rows in batch, it will keep the parameters the same for each row. ...

Hi Matt, There is a built in tasseled cap function for raster and mosaic datasets.  Please see this post. Tasseled Cap using Landsat 5 TM .tiffs in ArcMap 10.1 ... View more

Yes I use Python extensively with my templates.  I had to create the same set of three maps for several hundred polygon features, so I set up a template for each of the three maps I need, and used python to make a feature layer of each polygon ID in turn, zoom to it, then control each text elements already in the templates with data from the attribute table accessed via a search cursor.  All the layers I need for each map already exist in the templates and I have them turned on and off via python depending on other attributes.  So in the end I created ~2000 map documents and pdfs for the several hundred geometries in my feature class. I could post a sample code for working with one of the templates if you wanted to see what it looked like, the arcpy mapping module has a good amount of control for controlling elements within map documents.  I wouldn't post more than 1 though, since the code gets a bit long. ...

I would follow the instructions Darren has laid out for projecting your data.  As for which projection to use, I would use either an equidistant projection(keeps distance true), in this case try USA Contiguous Equidistant Conic, or a good local projection would be NAD 83 StatePlane Tennessee FIPS 4100.  There is a StatePlane for both units in feet and meters so which you pick is up to you(there is a search bar at the top when you are selecting output coordinate system, I typed all projections as they appear in the list, so they should turn up).  Incidentally, Tennessee is in UTM Zone 16N for future reference(fellow Tennesseean here). ...

You will need to project your input data to an appropriate coordinate system that uses meters: See (copy + paste the url).  http://resources.arcgis.com/en/help/main/10.2/index.html#//000800000048000000 The distances calculated by this tool are in the unit of the coordinate system of the input features. If your input is in a geographic coordinate system and you want output distances to be measured in a linear unit (as opposed to decimal degrees), you must first project your input to a projected coordinate system using the Project tool. For best results, use an equidistant projection or a projection intended for your study area (UTM, for example). ... View more

try just copying and pasting the link, unfortunately GeoNET has a nasty problem truncating links when clicked. The easiest way to get the proper formatting for your dataset will be to run it manually with the formatting of the start and end position.  You can then go to the geoprocessing results tab, and copy the tool as a python snippet and put the part you need into your script.  I would guess based off of your code you posted you would need to replace this: +vars.path_to_database+"/Parcel.mdb/Parcel/PARCEL_Limits,PARCEL_ID,-1,-1;ORD_NUM \"ORD_NUM\" true true false 25 Text 0 0 ,Join,\",\"," with this based on the parameters I used: +vars.path_to_database+"/Parcel.mdb/Parcel/PARCEL_Limits,PARCEL_ID,-1,-1;ORD_NUM \"ORD_NUM\" true true false 25 Text 0 0 ,Join,#,vars.path_to_database+"/Parcel.mdb/Parcel/PARCEL_Limits,ORD_NUM,0,25 Again I would recommend running it manually and making sure all the tool syntax is correct. ...

Hi Cynthia, I would recommend manually running it with formatting on the field you want, currently with the parameters you have set, it is not controlling the position of the text that is carried over. http://resources.arcgis.com/en/help/main/10.2/index.html#//00210000000s000000                 DISTRICTURL "District Website" true true false 100 Text 0 0 ,First,#,filepath/CountyDistrict,DISTRICTURL,0,25 This is what my field mapping for truncating the text on a field looked like, note it changes the character range at the very end 0,25. ...
