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 How do you embed iFrame content into a CartoDB infoWindow?
have a look at your url for the YouTube video. You're missing the http at the beginning. And your soundcloud url looks weird too.

comment How do I find out the resolution in (centimeters per pixel) of a TIF?
That would be in degrees. You could use this estimation that one degree is approximatly 111,111m. That means your pixels are approximately 5cm x 4cm. Does that seem right to you? That's pretty high resolution. I would follow @Ryan's advice and convert to a projected coordinate system. I am a bit dubious of the negative pixel size, however.

comment Any experiences or “gotchas” integrating Whitebox GAT (free and open) with the ArcMap UI?
Note, SEXTANTE for ArcGIS doesn't exist anymore. See this question.

comment Complex Viewshed Analysis
Vertical Mapper is just adding all the viewsheds together. If a viewshed raster from one point just has the binary values 1/0 for visible/not visible, then you can just add all of the rasters together. The result will be a raster with values from 0 up to n where n is the number of viewsheds you have. The values will indicate how many source points can "see" that part of the raster.

comment How to Import ESRI Geodatabase format .gdb into PostGIS
It is a commercial solution. You didn't specify you were only looking for free solutions. I think FME has a free trial period.

You might also try using QGIS.

Try downloading FME. Create a new workbench and add a Geodatabase Reader and a PostGIS writer.

Are you limited to using ogr2ogr? Or are you open to other solutions? FME should be able to do this easily.

comment How to use FME to parse .txt file to publish content to REST Interface?
I've never used FME Server, so I don't know what's involved in publishing. If you want to extract links from the text files, just use a Tester transformer. FME also has WMS readers which might be better.

comment How to use FME to parse .txt file to publish content to REST Interface?
What have you tried so far? Where are you getting stuck? Are you just trying to extract the WMS links? You could easily use a Text Reader and filter out lines which match an address or part of an address or some pattern using Regular Expressions.

comment FME - How to write all attributes when multiple source files have the same name?
Thanks Brad, have a look at my edits above. SchemaMapper won't be feasible for me, and I have tried the other options too. Still no joy.

I've also edited my question with additional information which may be relevant.

comment FME - How to add an attribute when schema definition is dynamic?
@MarkIreland, yes, that's essentially what I tried. I have done that several times in the past with no trouble. And to answer your question, the attribute doesn't actually get added to the destination feature classes. I will send my workspace to support.

This solution worked perfectly. Thanks @Ken.

comment How to determine stream channel Reach locations?
Is your network topologically cleaned? That is, do the nodes and lines touch? Is your network in a geodatabase? In a geometric network? If not, you might benefit from putting it in a geometric network.

@Liza, That is what this site is here for. It's how we learn.

That's what I was afraid of. Thanks anyway. I'll look into implementing this solution across the company.

+1 Nice answer, but I don't think this will work for me as others may need to edit a project. Please see the edits to my question.

comment Best way to enforce valid table names when writing to a File Geodatabase
I thought about that, but in order to fan out by that, I lose the dynamic aspect of the workbench. It also wants me to specify the allowed geometry which I won't know beforehand.
