Thanks for the feedback. I went with the ET GeoWizards' createCenterlines option. Pretty good results for my complex, messy dataset. Will require cleaning but was worth the investment. Greg

Thanks. The open pools seem to be the biggest challenge. I'll play with the max width setting.

I was planning on vector analysis. I could manually rank the primary canals (some are very wide and could accommodate large transport canoes). Secondary and tertiary canals could also be attributed with the remainder assigned to the thin canals separating individual beds. The idea being that I can identify which fields/mounds were associated with larger village/wharves I have identified based on travel costs.

Thanks. Looks like I may have to make the investment. I don't see it among ET Geowizards free functions. I'm guessing that it will correctly create lines for my "cul-de-sacs". Greg

Thanks, Here is a small area of the canal system. The white areas are raised agricultural fields or residential mounds. Trying to turn the canals into polylines for network analysis of movement through the canal system. There are some open pools and non-linear canal areas to add to the challenge. Greg

Hello, I was wondering if anybody has recently converted a complex polygon or raster canal network to centerlines? ESRI toolboxes or third party tools are moving targets so some of the old threads are hard to apply. The canal polygon network that I have was created by cutting out nearly 20,000 mounds and agricultural beds from a shallow lake system (archaeological example). The remaining canal polygon network is one large complex polygon. I converted it to a raster and tried the raster to polyline tool but ended up with a polyline feature class that filled in the canal cells with 800 million lines after running for a couple days. Obviously, not what I was looking. I didn't try the ArcScan vectorization since my raster was 1 or no data and ArcScan requires a 2 value raster. I can convert my raster and give that a try. Not sure if there is a method to convert my complex polygon directly to lines (centerlines). I'll attribute the resulting lines after the fact so I just need to create the skeleton or centerline features. Any ideas are welcome. Thanks, Greg

Since we are setting up a SDE, it looks like I can point to a data source in the SDE when creating the layer package. That should would. Guess I'm answering my own question.

It did work in Explorer when I saved it and loaded it as a layer package. However, unlike a feature class, the layer package (14.6 GB) took a long time to load. Probably too long for users in the office to load it when they want to use the layer.

Hi, I created a feature class with 6,500 geotagged photos with attachment/relationship tables. The photos display in ArcGIS using the HTML popup tool. However, when I add the feature class to ArcGIS Explorer the photos do not appear in the popup. Just the path, name, etc. appear. Any ideas? The popup content in Arc Explorer doesn't include any straight forward setting adjustment that would correct this. Thanks, Greg Luna GIS Specialist New Jersey HPO
