I have an excel spreadsheet that contains the elevations across the profile of a stream. I was wondering how to model this in 3-d. Basically there are 6 monitoring stations that are within a stream. I know the elevation of each bank, the slope of each bank, and the depth across the stream at each location. The depth was measured every 20cm across the profile of the stream. eg/ 0.35m across/depth 97.889, 0.55m across/depth 97.885, etc. I know that because there are only 6 stations, the result will probably be very blocky, but there are ways to fix that. Basically, I am just looking for somewhere to start. Like I said, I am pretty sure I have all of the pertinent information in an excel spreadsheet, just need to know how to get going. Thanks for all your help.

Hi All I am using ArcGIS10 Windows 7 on a 64-bit machine (more than passes the minimum requirements), with an ArcView license. When I am editing in ArcMap, some of the features that I can clearly see on the screen are not selectable, even though they are set as selectable in the selectable layers. Just wondering why this is. All of our features are stored in feature datasets inside of a file geodatabase. It's funny because I have a building layer, symbolized based on a field in the attribute table, and I can only select one or two of the buildings, both when editing and not. One minute this happens, and the next, everything is alright. Another problem that I have is features that are disappearing at certain scales. I do not have any reference scales set, they just are not there. Sometimes when I zoom out, they pop back up, right where they are supposed to be. Another problem... When I export a map, everything looks good in the ArcMap window, but once the export is complete (to a jpeg), some features are missing. I think everything is related somehow, but I'm not sure. Everything seems to be problematic with the layers being visible/selectable or not. Any help would be appreciated.

Have you tried the "explode" tool in the advanced editing toolbar. I don't know if this will work for you or not though, because I don't know if the roads are one continuous feature, or multiple parts to begin with. Worth a shot though.

Hello I have used both sets of software to georeference aerial photographs. There is really no difference in the quality of the finished product. As Robert said, the quality of the data that is being used for GCP's, the quality of the data being georeferenced, and the quality of the GCP's themselves is the major difference maker. PCI Geomatica is specialized remote sensing software that is used almost exclusively with raster data. You can georefernce, mosaic, orthorectify, and add/drop bands in the software on multiple photographs. The processing time, at least I found, is a lot faster in PCI Geomatica. I had to georeference a couple hundred air photos, and I used PCI Geomatica, mainly because of the large number that I had to georeference and the availability of the software to myself. I guess it really comes down to a users choice, but both sets of software run on the same principles when georeferencing. Hope that helps Andrew

I have done the same thing, except for a National Park in Canada. I had the same year intervals (10 years from 1949-2009) and I used the same settings listed above. I think it was an HP scanner. Saved the scanned photos as TIFF's and georeferenced them. Hope everything works out for you.
