I have map with a vector shape file and a raster DEM file. Only those two layers on the map. In the Table of Contents, when I right-click on either layer and click Zoom to Layer, the layer shows on the map. But, when I Zoom to one of the layers, the other layer does not show. How can I get both layers to show at the same time on the same map. Is this something to do with the Geographic Coordinate System or the Projection of either layer or the Data Frame? I checked the Properties and Source and all three show GCS_North_American_1983. Do I need to Transform or Project something?

Thank You! thank worked perfectly. I used the Windows Search on the main menu bar at the top and searched for multipart to singlepart. I deleted the small part and then Reshaped the large part, and then right-clicked on the Layer in the Table of Contents and Saved As Layer File.

I have a vector shape file with two "features" in it (see first image below). I would like to make this shape file look like the image below. I am using the latest version of ArcDesktop for Home, and ArcMap. I understand that I can click Editor, Start Editing and then use the small black arrow/pointer to select "features". When I click on either of the green areas (in Data View), nothing happens. In the Table of Contents, if I right-click on the layer and then click on Selection >> Select All, the entire layer gets selected but I am unable to select only one of the two green areas. I think I could use the Reshape Feature Tool to make the features above look like the image below, but the Reshape Tool does not work with multiple selections. This is the only layer in the map. The layer has a Geographic Coordinate System (GCS_North_American_1983) I don't know if this is a problem with the "Projection" or what. I opened a blank map and added this shape file so the Coordinate System or Projection should be the same as the Data Frame. Any ideas?

Thank you, I didn't even know the ContourList tool existed. I will check the tool and learn about it.

Thank you Xander and Joshua, I used your solutions and it worked perfectly. I really appreciate your advice.

The shape file with Contour Lines in the image below has a lot of data. I tried making the contour lines below very thin but the lines are so tight they are obscuring the terrain below. I there a way I can show fewer contour lines?

Thanks for the help, to solve the problem, I changed the properties of the DEM symbology. I used Classification and used the drop-down to change the number of Classes to 32, then I used the Information tool to find the elevation of the low land areas, then, in the Color Ramp, in the Range, I clicked on that color and changed it to no color. Then I used a base shape file below the DEM and gave the base a symbol and color to look like swamp/marsh. UPDATE: The solution above works ok, but there is also an alternate solution that works well. I used the Information icon/tool (looks like the lower-case letter "i" in a blue circle, and clicked on the area of the DEM that was swamp and that gave me the specific value for that area (in this case 379.19). In the DEM Properties, I choose Stretched and checked the box for Display Background Value. I put the value 379.19 in the Background Value box and clicked the "as" drop-down and selected No Color. Then I used a base shape file below the DEM and gave the base a symbol and color to look like swamp/marsh.

I should have included screen shots of the contour lines. Most are closed but a few are open. I should have mentioned that there are two layers, one with the contour lines and another that is a TIN which show the depth inside of the contour lines. Converting the contour areas to polygon removes the depth data. Maybe my question should be, how can I clip or re-create the TIN so that the TIN only shows the area within the contours. Maybe this is happening because some of the contour lines are not closed? If that is the problem, is it possible to edit the contours to "close" some of the lines?

The images below are kind of crude but I hope they help explain what I am trying to accomplish. The blue background is a TIN and the star shapes are from a shapefile with contour lines. How can I get the TIN to only show the data inside the contour lines? Do I mask the TIN or re-create the TIN? Or, extract by mask? The contour lines represent lake depths and there are actually many more lines within the shapes/lakes. The TIN shows the depths which are negative. The blue area outside the shapes is identified as having a depth of -5 so that area might be lowland or swamp or something but I want to exclude it from the TIN. If I try to change the color of any area that is -5 then I loose the color inside the shapes as well as outside the shapes. what it looks like now above and what I want it to look like below

Thank you all for helping to solve this problem. Thank you, le duc tri, for the YouTube video, I am glad I was able to watch it before it was deleted. Thanks, Curtis Price, for pointing out that I needed to use a projected coordinate system. At first I got an error message when I tried to run the Create TIN tool, 1) then I set the layer to the correct Projected Coordinate System but I still got an error message. 2) Then I set the Data Frame to the correct Projected Coordinate System and the Create TIN tool worked, BUT I didn't realize that the "Height Field" was a drop-down list, so --finally-- 3) I choose DEPTH from the Height Field drop-down list and then the TIN was created and looks great.

I'm pretty sure that the first thing shown in the video was to use the tool: ArcToolbox > 3D Analyst Tools > TIN Management Toolset > Create TIN I get a failure error every time. I am using a vector shape file with contour lines as the input. If I add the contours shape file and don't type anything in the features box, I get an error message the No Features were selected. If I add the contour shape file and then type "DEPTH" in the features box, (DEPTH is the name of one of the columns in the Attributions Table) then I get a general, non-specific 9999 (or whatever) error. I tried using various Spatial References and that didn't change anything. Do I need to do something with the contours shape file, before I use the Create TIN tool? Would it help if made the shape file available?

I watched the You Tube video create raster/ DEM from coutours line in arcgis - YouTube and now that I am at my computer with ArcMap running, now I am getting an error message stating: "This video is no longer available because the YouTube account associated with this video has been terminated" I can't remember the details of the video. It seems like a tool was used to create a "TIN" from the vector shapefile of the lake depth contour lines. Then, the TIN was converted to ?? something? Does anyone else get the YouTube error message? Do anyone see the video and remember which tools were used?

I'm new at this and learning as I go. Is there anything I should do differently? Or, should I just try your solution and see how it works? If it makes a difference the area is Quetico Provincial Park on Ontario, Canada, I'm not sure if that qualifies as high latitude.

‎12-27-2016

Thank You! I just watched the video and it looks like it will work great. I will try it later today and report back. I learned from the video that you can drag and drop from the Table of Contents (on the left side of ArcMap) to the pop-up window of whatever tool you are using.

Thank you for your help, I appreciate the assistance. I'm not sure I understand what to do. I already created a hill shade raster, do I create a second hill shade raster from the first hill shade raster? I don't see how the low level dark green gets separated from the high level dark green. If the dark green only appeared in the flat low swampy areas, I could separate it by color, but the dark green (or whatever color I pick) is ~both~ the low, flat swampy areas and the highest points of land. Is there a way to use some sort of "Extract" tool on the DEM data to extract just the low, flat swampy area data as a separate layer. If I could get that data as a separate layer, I could use a swamp or marsh symbol to represent those areas.
