From the FAQ on the ESRI Internship link Freddie posted: Is this a paid internship? Yes, internships at Esri are paid positions. Our pay scale is comparable to that of other software development companies. - See more at: http://www.esri.com/careers/main/internship-frequently-asked-questions#sthash.IO7ey33i.dpuf Nice.  Chris Donohue, GISP ...

Besides the advice listed above, you could also search for internships.  Many organizations need help on projects and internships can be a good way to get GIS experience.  For example, here in the United States, government agencies at all levels have many internships in GIS.  Non-profits and businesses have them also. Another way to go is to create your own internship by approaching an organization that has some GIS capabilities and asking if you can help.  This will take a bit more research and effort, but could yield a very beneficial position (and possibly a permanent paid position in GIS in the long run).

I wonder if maybe a more complete contour data set is available, which would save having to interpolate.  Here's some links that may be of help: topotools.cr.usgs.gov/contour_data.php Topographic Science nationalmap.gov/viewer.html The National Map: Viewer and Download Platform Chris Donohue, GISP ...

Interesting - your window seems different than any I have ever seen before in ArcGIS.  Are you using ArcGIS 10.3? I've never seen a "Define Scale Format" window like that before (and I have not used ArcGIS 10.3). Chris Donohue, GISP ... View more

I'll try using the 10.3 links from now on.  Not sure why the 10.2 ones don't seem to work anymore.... Chris Donohue, GISP ... View more

If you have access to the Spatial Analyst Extension, one possibility is to recalculate the No Data areas to a different value using CON: Conditional Evaluation with Con ArcGIS Help (10.2, 10.2.1, and 10.2.2) Con (Spatial Analyst) tool ArcGIS Help (10.2, 10.2.1, and 10.2.2) One caveat - doing so will universally change all No Data areas, so check to see if there are areas where No Data will still be appropriate.  If that is the situation, there will be other process steps needed to limit the area that is recalculated.

Mike: What Jayanta stated is correct - if you are labeling off a layer, it will label all features, even the ones whose symbology you have removed out of the layer via the symbology tab.  To repeat, removing the symbology does not suppress the labeling of that removed feature. A Definition Query will work, though, in removing the unwanted features AND its associated label.  The trick is to know what query to set up to exclude what you want excluded. I'd go with Jayanta's suggestion of making a new field and populating it with zeroes and ones to differentiate what you want to show from what you want to suppress.  Then use a Definition Query on the layer to suppress the things you don't want shown based on those values you entered.  There are also other Definition Query possibilities that could work (and may not require the addition of the field), but we would need to see more of the data to formulate an effective one. --------------- More examples of a Definition Query at work: All features shown and labeled (starting state) "P/QP" category suppressed via Definition Query.  Both feature and label are now gone. Definition Query used on layer to suppress "P/QP" category for above image. Chris Donohue, GISP ... View more

Adding Melinda Morang here (ESRI Network Analyst Expert) in case the system doesn't automatically forward it to her.  She may have some ideas. Chris Donohue, GISP ... View more

One potential solution is to do a Definition Query on your layer.  In the example below, NOT was used to suppress the display of "LDR" attributes.  Note- in the example image the labels being displayed are annotation that I purposely left on to show where the LDR was; however, if they were labels the LDR ones would not show. ArcGIS Desktop EDIT - fixed example image - used wrong field for definition query in original image. Chris Donohue, GISP ... View more

There are a variety of aerial download sources that can be found by a web search.  I'd try a Google search on "aerial downloads" and "orthophotos".  If you want a specific geography instead of the whole world, I would add in search terms related to that geography.  For example, "aerial downloads United States". Another avenue to search is government agencies, as often they are providers of imagery. Here's a few of the many results a quick search revealed.

Robert: From what you have related so far, it sounds like Standard fits what you need.  However, available budget will likely be a limiting factor, so I'd try to get a sense from your sponsors how flexible the budget is. Also, there are some other considerations when purchasing GIS that people often don't take into account: 1.  Maintenance/Updates.  The software does change over time.  Buying a copy of ArcGIS will give you the software now, but after a year it will start to become obsolete and over time will essentially have to be replaced or upgraded.  So keep that in mind for long-term budgeting, i.e. this is not a "buy it once and you are done" software.  You will have to plan out budget to keep ArcGIS updated, be it by purchasing Maintenance or re-purchasing ArcGIS in a few years.  Also, depending upon your needs, it may be worth it to purchase Maintenance not only for the continual upgrades but also for the Tech Support that comes with it. 2.  Extensions.  Depending upon what things you forsee doing with GIS, you may need to buy an Extension.  As one example, the Spatial Analyst extension is very popular with many GIS users.  You may not need any extensions right away, but keep them in mind, as inevitably as one gets GIS up and running folks will say "hey, this is cool, but can you do this additional task also".  My experience is that if you can budget extensions in up-front, it is easier to implement them than if someone asks for a task to be done requiring an extension and one has to tell the requestor it will cost  a few thousand dollars to get the Extension to make that possible.  Also, having an extension  involves maintenance and upgrade considerations (see #1).
