comment ModelBuilder Output Creates .lock file and Cannot Overwrite When Ran a Second Time
You say "My model is very simple" - can you use the edit button beneath your Question to revise it with a more detailed description and graphic(s) which will enable us to try and recreate it as a test, please? At the same time you could revise it with any other clarifications that have come out of the Comments so far. Keeping your Question "standalone" rather relying on potential answerers to assimilate a Comment trail using leads to quicker and better answers.

comment Splitting polyline by points using ArcGIS 10.2 for Desktop?
Can you edit your Question to explain why you want split this polyline, please? My suspicion is that Linear Referencing may provide a more suitable approach.

comment How do I create an index layer for multiple maps?
Can you replace (or add another to) your existing graphic which shows what the grid you want to create would end up looking like from a starting point of a simple polygon, please? I think the tool @mattwilkie suggests will do the trick but I may not be picturing what you are asking for correctly.

comment How do I create an index layer for multiple maps?
@mattwilkie Any polygon feature class can be used as an index for Data Driven Pages - the features do not have to be rectangles - I am sure that this has been the case since they were introduced.

+1 to both of you for excellent Q&A cc @ChrisW

comment Use Python lists in Field Calculator?
Technically I think this is a pure Python rather than GIS Question and would be better researched/asked at StackOverflow with references to the Field Calculator removed.

comment Any updates on problems with loading ESRI FileGDBs in QGIS 2.2?
@Frank Just saying "it didn't help" is not as informative as saying at which step what you observed started to deviate from what you expected and how.

comment Why is ArcGIS Server 10.0 getFeatureInfo not being buffered?
Perhaps you can edit your Question to be more along the lines of "there is a possible solution to how to effectively increase the search tolerance described in another Question but this Question is about how to implement that using OpenLayers". If there is ever another Question which looks like a possible duplicate floating around I think it is best to reference it early so that you can explain as background why it does not simply provide an Answer.

comment Why is ArcGIS Server 10.0 getFeatureInfo not being buffered?
gis.stackexchange.com/questions/7871/… looks highly relevant - the main difference seems to be the use of OpenLayers as the WMS client here.

comment Using PostGIS functions in ArcGIS Desktop for Layer Definition Query?
This may be related gis.stackexchange.com/questions/68288/… but uses Oracle Spatial rather than PostGIS.

comment Can ArcPy's AsShape be used with GeoJSON FeatureCollection of Polygons with Labels?
Thanks for posting this - my application only ever needs to ingest a handful of polygons (with thousands of vertices each) so I had not noticed that bottleneck on the code I put together. I'll use an InsertCursor rather than Append next time I encounter this requirement.

comment Digital Number (DN) on satellite imagery?
The Q&A format of GIS SE works best with one question per Question so I recommend that you edit yours so that it is clearly focussed on the one of most importance to you. You can then research/ask the others separately.

comment Merging data using FME
Welcome to GIS SE! As a tip, your answer is hard to read due to your use of a contraction (attrs) that is not written out in full even once. For readability I recommend that such contractions are not used.

comment How to fix shape file projections
@AntarrByrd Please try to get into the habit of responding to Comments by using the edit button beneath your Question to revise it with any clarifications that we seek. GIS SE is different from other discussion forums and Q&A sites because here we try to expend our efforts on the focussed Q&A (that then has ongoing and easy to digest information for subsequent people who encounter the same problem) rather than discussion.

comment How to fix shape file projections
@AntarrByrd I'm confused by your terminology of "directly importing it" which you have used in a Comment and perhaps elsewhere. The 5 step workflow I outlined has nothing that I would refer to as an import.

comment How to fix shape file projections
@AntarrByrd Your graphic indicates that you chose one of the original shapefiles and projected it from NAD_1983_UTM_Zone_15N to NAD_1983_UTM_Zone_15N i.e. no change, so what you are seeing is to be expected. The shapefile that you said you downloaded in the other Question was called METRO_Bus_Routes.shp and it had NAD_1983_StatePlane_Texas_South_Central_FIPS_4204_Feet as its coordinate system. It is this downloaded shapefile that should be projected following my instructions in this Answer.

comment Why is shapefile not drawing in expected location after (or before) using Define Projection tool?
"How to check whether suspect shapefile is geolocated where it should be?"

comment Why is shapefile not drawing in expected location after (or before) using Define Projection tool?
@AntarrByrd That is always possible but not a conclusion that I would jump to when it is so easy to test by researching/asking it separate from this Question.
