I have over 11 years in the geospatial industry. I primarily use ArcGIS, MapInfo, and FME. But I'm interested in learning QGIS and GRASS. I'm also in the process of honing my Python skills.

comment Querying Data with a 1-Many Relationship Class
@Jens This isn't exactly what I was hoping to do and it would be nice to be able to select the vegetation attributes from the point feature class. However, this method will work just fine for my purposes. I have seen that button in the attribute table many times, but rarely work with relates so I forgot about it. Thanks.

comment I need advice in using QGIS Lisboa 1.8 (vol 2)
What do the polygons and dots represent exactly? As the others have mentioned, please expand your question in as much detail as possible.

comment How do I access an attribute table within a shapefile and replace values?
Field calculator would work well, but I don't think it's as fast as an update cursor. And the translate method is faster than replace (link)

comment OGR Python bindings
Is your folder path spelled correctly? It looks like there's a folder in it that should be spelled "ClusterCleaned" or "ClutterCleaned" not "CluterCleaned". Though that is a guess, obviously.

comment How to incorporate drop-down list within cells of shapefile attribute table using ArcGIS 10.0 or 10.1?
Why not just use domains and subtypes? That's what they're there for.

comment Reclassify raster tool in ArcGIS 10 creating no-data cells
When you say "cells which previously had data appear as no data" do you mean, they had data in the DEM? What is the projection of your DEM? Is it in a geographic coordinate system? If so, you will need to reproject it to a projected coordinate system and recalculate the slope. This may be the problem.

I would try to update the computer that isn't working to a newer service pack. If that still doesn't work, let us know.

@whuber, that makes sense. Thanks for the info.

comment Are there any rules of thumb for the neighborhood settings in Focal Statistics?
I'm not really sure of the correct answer, and I'm curious to see what answers people will post. But, since tree canopies are, in general, roughly circular, then it seems reasonable that a circle would be appropriate. Maybe even a square, but probably not a wedge or an annulus.

comment How to prepare layout to print multiple images on a page using Arcgis?
@Mapperz, I don't think DDP is the correct solution here. The question is about multiple images on a single page.

@golmschenk do you have the actual polylines of the subways? If so, you could use some linear referencing tools.

Have a look at this page which has instructions for viewing your data in 3D.

comment How are you, as GIS professionals, spending most of your day at work?
@BradHards, it's really just for my own curiosity, though, I feel that others may benefit from this information. I sometimes feel that GIS professionals in my workplace can get pigeonholed into different roles. Plus, I wonder if there are things that others are doing that I'm not and should be...

comment How to export only certain columns to a CSV file in ArcGIS?
Does anyone else know what is going on here? Does anyone know why the Shape field was being written to the file? While @sgrieve's code possibly improved my code, it did not solve the issue.

Can you elaborate a bit more a bit your process? Maybe edit your answer to include the Excel formulas so that others may benefit from the answer.

No, I don't think they do. Just live positions unless they can't get a current fix in which case it will use the last known position (at least I know Find My Friends does this)
