I've been in the geospatial industry since 2002. I primarily use ArcGIS, MapInfo, and FME. But I'm interested in learning QGIS, GRASS and other open source GIS software. I'm also in the process of honing my Python skills.

comment Using python elif syntax in Field Calculator to reclassify a range of values from a different field and populate a new field
Is it possible that you have a selection on the feature class? If so, you may only be calculating on the selected features and not seeing the changes.

Is it possible that the values in pa_gNy_ha are less than zero? Is the field definitely numeric?

comment Assigning ID to features with similar attributes
Can you please clarify your question? Do you mean want to concatenate the three attributes? So the first record would be 1133125? Then, ID would be 1. If another combination of attributes is also 1133125, then the ID would also be 1? Or do you want the ID to just be the concatenation of the three fields?

Is the field you're updating a text field?

comment How geographically accurate is Google Earth?
In my experience, islands are less accurate on Google Earth than mainlands. I have seen an island in Australia that was split vertically between two different images. The difference between the two was about 50-100 metres apart. I think they've since updated the imagery there and it looks better now. But, generally, I wouldn't trust the imagery for anything important.

comment Python add-in user input not working ArcGIS 10.1
It might help us answer if we could see your code. Specifically the areas where the hardcoded parts work.

comment VB Script can't run in Field Calculator
I don't really know vbscript but that pipe character at after a="N" looks like it could be the culprit.

comment How to recode and recalculate Field Values using ArcPy?
I think you're making some huge assumptions about peoples' marital status. Not every married couple share the same last name. Also, what if two people who are not married are at the same address such as brother and sister?

comment Calculating a Unique ID on a Subgroup of Polygons
You're probably not going to get away with doing this without some kind of a spatial join. Have you thought about incorporating this script?

Have a look at the PointOnLineOverlayer transformer. Also the SpatialRelator.

comment Is there any problem with Service Pack 4 for FME?
This question appears to be off-topic because it is about an issue with an old version of the software and the person should have had a response by Safe Software since it was asked.

You should try implementing this as a Python Add-in. They allow user interaction.

comment How to identify gaps in linear point data in FME?
In theory, this makes a lot of sense to me. However, I couldn't figure out how to compare the M value to the previous one.

@BradNesom, could be, but I'd still like to identify it.
