You should not be able to determine a lake depth based on surrounding topology.   Lakes are formed in different ways and that is a significant factor in how deep it is. Typically very round lakes are often meteor impacts.  They will be very shallow and have raised edges.  This is not always true.  We have a large lake near where I live that is very round and has raised edges but is exceptionally deep and is fed by a spring at 106 feet. Thin very deep lakes are often formed by glaciers or erosion etc... what state are you in?  Some states DNR's provide bathymetric A DEM will typically show the elevation of the lake surface at the time it was made.  Bathymetrics used to be made by throwing a weighted rope into the water and marking how deep it goes.  modern technology uses sonar.  The technology used to generate modern DEM cannot penetrate water surface. You are right the DEM does not have bathymetry, the lakes just show up flat. Ist there I way to calculate the depth by using the elevation of the surrounding areas? Thank you so much for the help ...

if you only need to do it once don't over complicate it. just create the new attribute with the name you want and then populate it with the attributes from the old attribute. Or if your careful simply rename it in Access. Hi, Can I rename a feature class attribute with ArcObjects (FGDB, SDE) ? I'm using IClassSchemaEdit4.AlterFieldName and it seem to work in a FGDB. I'm asking the question because I have often read that I can't rename a feature class attribute with ArcObjects... Thanks ... View more

After you create your legend right click on it and select properties.  Click on the Items Tab. Select the feature you want to only show items when visible. Under Map Extent Options check the box for Only show classes that are visible in the current map extent and check Use Current index feature as the map extent (data driven pages) if you want the legend to ONLY display what is on that Data Driven Page If that does not work I would say  your page definition is interfering. Try hitting refresh data driving pages button after you customize your legend. ... View more

Are you using the same MXD when you do this. Try it again on the same section of feature in a brand new MXD and use the same features to try and duplicate it. If it does not crash you may have an issue with the MXD you are using. If this is the case recreate your MXD by using the Select Elements tool in Layout View.  Select all elements and COPY.  in a new blank MXD layout view move the existing data frame out of the way.  set your page size to what it was in the original  mxd, if you had set up the layout for printing.  Paste to copied elements. and save your mxd. ...

I am not familiar with the method you are describing. When I have had to do it I use the COGO tool to draw lines.  I then add the points and snap them to the end points of the lines.  If your in a geometric network it should create a network junction at each end that you can then copy paste into your point feature class I am trying to create a feature, placing a point at a specific length and angle from an existing point. I use the point at the end of a line tool, click on the existing point with snapping features on, and click ctrl-L. I type in the length and units (7 m). The UI goes away and the length is not fixed. It will work without units, but then i end up with the map display units. This used to work a month ago. I'm using 10.1. Is anyone else having the same problem? Thanks. ... View more

What your saying is you have a feature class that is linked to images. I don't think you can do that.  Instead you may have to create links to the images in Google Earth Hello, I want to convert a feature class to kml, which is part of a FGDB, the same feature class contains a field of raster which contain photos. I want to convert this feature class to kml file, which should be displayed the photos too in google earth. Please help me if anyone know the solution. Regards Johnson ... View more

Double click on the feature in the table of contents to open layer properties.  The click on the General Tab then select a scale at which to become visible. Start with 1:24,000 and see how that works. also, do this for as many of your features that do not need to be observed at full scale.  Labels as well. The more features you have to draw the longer it will take. A good part of it is also hardware.  Better graphics cards and better CPU's and RAM. IF it is something that people need to add on occasion then set your desired scale for the shape file and save it as a layer file.  then when someone just needs to add it real quick it will not become visible until the desired scale is reached. ...

determine the logical order in which you wish to create your lines and create them from point to point. I just did something similar for 65000 Transmission Structures. I took the x,y coordinates into excel and sorted them the way I wanted them to draw then filled in the ToX and ToY with a formula and then used the XY to Line function to create the line segments. ...

Go to the layer properties in your attribute with the leading zeros. Click on the display tab and then the Expression button. Where there is the check box for Advanced click that. Now write this in your dialog box. or copy paste if it works Function FindLabel ( [TextTest]  ) if instr(3, [TextTest] ,1)  then  FindLabel = left( [TextTest] ,2) & mid( [TextTest] ,(instr(3,[TextTest] ,1)),10) end if End Function Where it says [TextTest] change it to your attribute Now this is important.  The way it is in now it will only do it correctly for the strings that start with a 1 after the zeros. Copy and paste everything from and including IF to End IF change both of the 1 to 2  paste again for each number through 9 and change the 1 to the next number.  make sure End Function stays at the end. Where you see the 10 that is the number of characters after the zeros to display.  If your string is longer than that increase the number. ... View more

Are all the fields similar in that the first character is a letter and the second is the  "-" symbol and the third is a Zero? Hi, I would like to have the leading zeros removed from the output results.  For example when a feature is selected and the attributes are displayed I want it to show L-12345 not L-0000000012345.  Or if you do a search by typing in L-12345 and not      L-0000000012345.  Is there a way to do this in the esearch widget tool?  Thanks! ...

Looks like UTM Meters.  I tried to place them and came up with a location to the west of Marseille. You should go back to the source where the Lidar Data came from there should be Metadata that tells you the projection/coordinate system used. Hello, I have a problem here, indeed, I used an ASCII file from LIDAR data but I want now to define a coordinate system. When I open the ASCII file, it gave me a list of numbers : 545023.50 299909.50 8.33 545024.50 299909.50 8.70 545025.50 299909.50 8.80 545026.50 299909.50 8.79 545027.50 299909.50 9.01 545028.50 299909.50 8.41 545029.50 299909.50 8.52 545030.50 299909.50 8.54 545031.50 299909.50 9.11 ... I understand that it is X, Y and Z coordinates but I don't know in which coordinate system. Does anyone have an idea ? (It is supposed to be in the North of France, on the coast) Thanks in advance, Take care, Joss ... View more
