I typically do use procedures similar to Watershed when I'm delineating stormwater subcatchments. However, in this case, my polygons won't be terrain-dependent. I have to draw them in based on service connections. So in other words, my procedure would ideally be: 1. Activate the script (the basis or language of which I am requesting in this thread) 2. Create a polygon feature (assume the feature class name is Shapefile_P) 3. Script would prompt me to click on a node (which would be in a points feature class, Shapefile_N) 4. Based on selection, script would read the associated NodeID from Shapefile_N and place this data in a field in Shapefile_P. 5. repeat forever on end Hopefully that provides a little more clarification on my end goal.

GIS Gurus, I am a baseline GIS user and unfortunately not too knowledgeable/savvy in scripts/advance programming. I'm looking for a script (or any other advice you can provide) that will automate a rather tedious process that I've encountered... I have a point feature class with over 1000 unique entries, each representing a node in a water network. Each node has a Node ID associated with it. I am creating a polygon feature class which contains areas contributing to each node. Ideally, I would like a script which allows me to draw the polygon and then prompts me to click on which node the polygon is associated with. This selection would in turn populate a field in the polygon feature class with the Node ID. Does anybody have anything they can share that would accomplish this? Or know where I can start? Thanks in advance!

At present, I have ArcGIS 9.3.1 and have purchased several tiles of LiDAR data (XYZ format and LAS format) for my entire county. Can anybody provide any guidance or direct me to a procedure somewhere that outlines how to convert this data into smooth, seamless contour data? Can this be accomplished in ArcGIS 9.3.1? Is there additional software that will handle this task better? Thus far, I have found procedures that show how to convert these tiles by using the LAS to MultiPoint utility, and then creating surfaces/contours using Spatial and 3d analyst. However, the contours do not match up at tile boundaries. Any thoughts, recommendations, or advice are appreciated.

If you know your groundwater elevations, you can make a point feature class, create a TIN surface from it based on elevation, and then use Spatial or 3d analyst to create contours.
