comment Can custom map tiles be consumed via ArcObjects within my ArcGIS 10 Desktop AddIn?
He said "no ArcGIS server" - straight Apache only, otherwise, it's dead simple, as you say.

comment gdalmerge produces file that is much too large
For future reference - mine, if nobody else's - gdal.org/frmt_gtiff.html has the set of GeoTiff specific options that you should be able to use for any of the gdal commands. Depending on the type of imagery you have, you might want COMPRESS=LZQ or even JPEG; it'd be well worth the time to verify the type of compression used on the source images.

comment How can a single line be computed from multiple possibilities
I'm experimenting with a spatial analysis approach - adding values in a continuous space, in effect - as well as attempting discrete analysis by segmentation and cubic spline curve fitting. As you say, some combination of the two (yikes!) may be of interest.

comment How can a single line be computed from multiple possibilities
Ummm. Sort of; to partially quote your answer "A direct combination of two paths is highly problematic.", which I take to mean that this is in the category of problems not readily solved for automatically. The trouble would appear to be identifying the discrete bits of ridgeline and then connecting them, is that correct?

ArcGIS 10 documentation is over this way: help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/…

comment What type of interpolation to visualize metal detection survey data?
(Note to self: stop hitting "enter" when adding a comment) You'll need Spatial Analyst, or Geostatistical Analyst if you're using 10. You want a function called "Interpolate to Raster". The exact process will vary depending on what you're trying to accomplish; you can try a very simple inverse distance weighted interpolation and see what you get. The choice of the color ramp that you use for visualization when done is going to affect what people's attention is drawn to - domain knowledge of the data involved is pretty critical here.

Sure, at least in general terms.

comment How to convert GML to features in ArcObjects?
I don't know of anything in ArcObjects that deals with GML. As far as I know, you're on your own to build the mapping between the two technologies, which is a daunting enough task. I should have mentioned that looking into the .NET Topology Suite might be of some benefit; if they're not supporting GML, it might be worthy of an extension into that project. Also meant to ask - do you have control over the server side as well, or just your own stand-alone client?

comment Ensure BaseDynamicLayer is always the most visible layer
I assume you'd have to get IActiveView and subscribe to IActiveViewEvents.ItemAdded. Details are sketchy (ok, non-existent) w/o firing up a compiler, though.

comment Ensure BaseDynamicLayer is always the most visible layer
I'd assumed that he was in control of things being added - it's ArcEngine. In ArcMap, you'd have to catch the event when someone added data to the TOC, but here, you've got control of it.

Good catch, thanks. That'll save some frustration.

comment ArcGIS Server 10 - Licensing by Core
Pain and suffering from a performance standpoint, particularly if a lot of disk activity is involved. If you're using SDE and your DB is not virtualized, it's less of a problem. It's still promoted (sort of) by ESRI: esri.com/library/whitepapers/pdfs/…

Yep. And as @petr_k mentions, the compiler won't allow it. And it was a red herring anyway - the real issue is what Validate claims it might do vs. what it really does....

Neat. So ESRI's documentation is ... off. Righty-ho. Off to the compiler I go, then.
