comment What are useful websites for scouting GIS related jobs?
np re undeleting after editing & fixing, and sorry for moving the goal posts. I was responding to complaints to mods and felt the need to move quickly. Although I gave 1 days notice but didn't actually do anything for over 2. In retrospect the urgency was perhaps overly strong.

I think he's asking for how to do this from code.

comment Selecting Multiple Layers under Table of Contents
Hi Kev84, Welcome to GIS.se :) Isn't this really the same question: gis.stackexchange.com/questions/7746/… ? Instead of posting a new almost-the-same question you can edit your existing question, or add clarification in the comments to it.

comment What is the difference between DEM, DSM and DTM?
@whuber We built drainage enforced elevation models for our region from contours, watercourses, and other ancillary data. Following WolfOracle's definitions, this product would properly be called a DTM. However in the 12 years since generated we've referred to it in publications etc as a Digital Elevation Model, perhaps in error. It's always been distributed in a raster format but some have converted it to TIN etc. to work better in their native environment. In general use I don't know that the elevation/terrain distinction is truly useful without prefacing the discussion with definitions.

comment Alternative cartographic software programs?
Welcome to GIS.se :) Please point out Manifold's cartographic attributes which make this an answer to the question, otherwise it reads like spam. I didn't downvote your answer, but I expect that's why someone else did. Unfortunately mentions of Manifold trigger this reaction more readily than other softwares do. In other venues Manifold users have tended to be rather...enthusiastic... in extolling Manifold's virtues and criticising others' shortcomings. So people are wary.

comment Alternative cartographic software programs?
Sorry Brad, "Avenza" is "Avenza MAPublisher", which is the same package he already said was unacceptable.

comment Free good quality small scale (1:70,000) global coastline datasets?
I'd be happy be to proven wrong, but I think the answer is: there aren't any (integrated) global coastline datas less than <1:500,000 nominal scale, or even <1:750k, even for a price. Of course I'm curious as to what use a global 70k dataset would be.

comment What are useful websites for scouting GIS related jobs?
whuber is correct, in order for this thread to remain viable, the recommendations must have supporting commentary and evidence as to why you are recommended the site. I will delete answers which do not have this, starting tomorrow.

@underdark, new users don't see the [add comment] link on other people's answers until they've reached a certain reputation, 50 I think. I can't believe I forgot about that as it was a very sore point with me when I first joined Stack Overflow.

comment What are Raster and Vector data in GIS and when to use?
@whuber that's wonderful. Yes it's part of what I was thinking of. I'd love to have taken part in that discussion. My take home for the day is "Spatial structure and content are different. Structure is a container for the content.". It's a point I've often had frustrated conversations over, the difference between the precision of the storage format and the precision of the data (just because a raster elevation model is using 15m cells doesn't mean it's accurate to 15m).

comment ArcGIS 10 tool (add x,y) is not working
everyone, please use comments when asking for more information and/or conducting a back-and-forth exchange and reserve answers for answers. The design and purpose of the site's system is to make the final solutions float to the top and not get buried in traditional forum-style threads. Thanks. (also see gis.stackexchange.com/faq)

@ Jose, por favor, ver preguntas Manejo de los no-escritores Inglés. Nosotros simplemente no tienen una gran base de usuarios suficiente como para utilizar varios idiomas. Siéntase libre de utilizar su lengua nativa en el SIG sitio de chat.

@Jose, please see Handling questions from non-english writers. We simply don't have a large enough user base to use multiple languages. Feel free to use your native tongue in the GIS chat site.

comment What are Raster and Vector data in GIS and when to use?
@Pablo, there's material there for an answer, or perhaps better yet a question, "what are representative, educational, examples of vector data misuse?"

comment What are Raster and Vector data in GIS and when to use?
I don't see how thinking of raster as a specialised type of vector is helpful to understanding. Could you please elaborate on how this perspective has helped you?

comment What are Raster and Vector data in GIS and when to use?
Thanks David. :) There's a variant attributed to C. Dana Tomlin that goes "Yes raster is faster, but raster is vaster, and vector just seems more correcter." (ref)

comment Convert a shapefile with northing/easting to ASCII raster with latitude/longitude
eep! you're right, thanks for catching that. I've changed the order.
