Thanks Gregory! That was the solution I needed. Just was missing that little bit. ... View more

Do you have a TIN, DEM, or Terrain for the area? Your best bet would be to create contours using either Contour or Surface Contour from one of these datasets. Depending on where you need the data for, there are a lot of sources (global USGS, government, or even purchase from private vendors). It is possible to create a TIN from your contours and then re-generate 1m contours, but they would not accurately represent the true ground surface so I would not recommend it. ... View more

If you happen to have Adobe Acrobat Pro, what I do at work is export my PDF with all of my layers turned from ArcMap and then open it up in Adobe Acrobat Pro. Go to the Layers view on the left, and right click on a layer you want to be turned off by default and choose Properties. In properties you can set the Default State from "on" to "off". Then just save your document and it is ready to go. If you don't have Pro, maybe Nidhin's link will help you sort it out in ArcMap. ... View more

Do you have access to the original Lidar? Your best bet would be to get the ground points from the Lidar and build either a TIN or Terrain using the Lidar ground points and the breaklines. You can generate contours from your DEM using the Contour tool. If you want to incorporate breaklines, you will first have to convert to TIN. Then after adding breaklines, use Surface Contour. But you've lost a lot of accuracy from the original Lidar by starting from a 1m DEM, so unless the county won't share the Lidar I'd use that. ... View more

Have you tried Hawth's tools? It is a free toolset with lots of helpful tools for environmental analysis. There is more than one way to do your task, but Hawth's Tools might be useful for you in other areas: http://www.spatialecology.com/htools/tooldesc.php and this tool should do what you want: http://www.spatialecology.com/htools/regpnts.php ...

When using the Create TIN from Features tool, define your clip area polygon as a "hard clip". If you've already generated a TIN, you can Add Features to TIN (also hard clip). ... View more

If your goal is to get your data in GoogleEarth, you can just Export to KML from the Conversion tools. It will take care of the coordinate conversion for you (we commonly export from a local coordinate system). The coordinate translation will cause some shifting of data based on the coordinate translation, but considering GoogleEarth is used for visualization instead of analysis, it probably won't be a problem. ...

I've had this problem too, as have many others: http://forums.arcgis.com/threads/63443-ArcScene-10.1-near-non-functional-with-TIN-(face-elevation)?highlight=tin+10.1+arcscene It seems that 10.1.2 should fix it (or 10.2 if you can upgrade). I can't confirm as I pretty much stopped using ArcScene because it was too slow and the 3D visualization capabilities aren't that great (CityEngine is way better). ... View more

I think you need either a raster, TIN, or terrain to run the volume tools. Use the conversion tools in the conversion toolbox to convert to a raster (ASCII to Raster). Then use the Surface Volume tool and give it the elevation you want a volume below or above. If you don't need the entire area, you'll want to clip your raster to only your area of interest. ...

Hi! I've had that issue with the crazy lines on profiles too. The fix that worked for me was to select the entire trail segment you want a profile for and then create a route (Route Editing toolbar). This ensures that your trail is properly linear referenced (added bonus that you can label distances in plan view to match your profile view). Not sure on the automation bit. ... View more

If you don't have ArcGIS, you can use Corpscon to do coordinate conversions. http://www.agc.army.mil/Missions/Corpscon.aspx ... View more

Depends entirely on what you want as an output. If you just want a peak flow rough estimate, you can use the rational method. Then you only need your drainage area (watershed area calculated in GIS), the runoff coefficient, and rainfall intensity. If you want anything much more complex, you will need to use a hydrologic modeling software (HEC-HMS is a common free one). GIS can help you get much of the input needed for these models including basins, streams, curve numbers, and time of concentration, but the modeling software will require other inputs such as your storm hydrographs and any gauge locations for calibration. ...
