Could you update your question with what software and versin you are working with? A screen shot of your situation might help bring clarity as well. Use the Edit button below your question.

comment Build Polygons from Polylines
@Rob, you are right. It's not the appropriate place to ask. I think it's an excellent new question, and you should really post it. Even if this is basically the same question, you have different software available (be sure to list all you have: arcgis, fme, qgis, grass...), therefore making it unique (at least from this one). However, I suspect it might be hard with a basic licence and no 3rd party software. But let the community share its combined knowledge!

comment How to perform mass-balance analysis with ArcHydro
ArcHydro can't handle flow volumes or water levels. For that you either need @WhiteboxDev's tools or some specialized application like Hec-ras or Mike 11/She/21/Flood (several different programs in the same group).

comment Stream Segmentation in ArcGIS
Hydro ID's are just identifiers, nothing fancy about them. And it doesn't decide - you do it yourself in Stream segmentation (when you enter the threshold value). Notice the value range on your stream link grid, the highest value should coincide with the amount of catchments later on.

comment Stream Segmentation in ArcGIS
Although an interesting question, I've always viewed Stream segmentation as a necessary but (for the outcome) irrelevant function. The result is only used as basis for deciding the lowest point in each catchment and assigning unique hydro ID's for each segment.

comment Lining up polygon legend patches in ArcGIS for Desktop?
I've noticed sometimes (with points mostly) that symbols wont line up properly in layout view. However, when exporting it looks good. Have you tried exporting and see what happens? A quick-and-dirty workaround is to convert to graphics and edit them manually, although that won't really solve the underlying problem.

comment Categorizing polygons instead of using default single symbol in ArcGIS for Desktop?
So is it different source data that you add each time, or the same feature class? If same, you can use a layer file to preserve symbology when adding next time. If not, is it always the same field (with the same values) that you want to categorize from?

comment Removing incorrect (non-ground) points from LiDAR data?
I have just started using a program, FugroViewer, which is good at displaying LiDAR data in 3D etc. At least that makes it easier to identify where you have points that ain't aligning. Not sure yet if it can edit points as well (but Viewer in the name might be a hint that it can't).

comment Exporting data in XML file format from ArcGIS for Desktop?
@WhiteboxDev Well, it might not be considered reason enough for downvoting, but our Help also states that one should thoroughly search for an answer before asking [a] question.

comment What is the precision of a Geohash
When it comes to that, it's not so much about how decimals you have but how many that are relevant. See here for an answer to your question: gis.stackexchange.com/questions/8650/…, but pay attention to the difference between accuracy and precision.

comment Assign points to another point layer's value
I suggest that you try to create a script tool based on Radouxju's pseudo code. If you run in to trouble along the way or need help to implement certain functions in your script later you should ask a new question about that specific problem. Good luck!
