comment When to reproject LAS data?
Welcome to GIS SE! It can be difficult at first, but as much as possible try to focus your Question down to a single question (mark). That way you are likely to get a clear Answer to your single clear Question.

comment Creating a python script to import an excel spreadsheet, create shapefile and do some analysis
@Alex Rather than having a rolling Q&A, which is not what GIS SE is designed to do, I think you should Accept an Answer on this one and separately research/ask your new question about how to create a Python script tool from a Python script. You should be able to find this in the ArcGIS Desktop Help.

comment Accessing organisational webmap using downloaded Basic Viewer of ArcGIS Online?
Welcome to GIS SE! As a tip, I think you should always spell out AGOL the first time you use that abbreviation in a Question here because it is one that many will be unfamiliar with.

comment Is there a way to automatically select a feature when another feature in a different layer shares attribute data?
It is a shame that you are restricted to 9.3 because I think the Page Definition Queries of Data Driven Pages would make this easy.

comment Creating a python script to import an excel spreadsheet, create shapefile and do some analysis
You say that you are stuck on the first step so I think you should edit this Question to focus it on that, and then research/ask about the subsequent steps separately.

comment Segmenting road from Excel spreadsheet based on specified distance?
Your Question seems to be a mix of Linear Referencing requirements and How to Partition Line into Segments using ArcGIS for Desktop?. Would you be able to edit it to make what you are asking clearer, please?

@blah238 I think all those links would be great to add to an existing or new Answer at gis.stackexchange.com/questions/61862/…

This sounds more like what you are after gis.stackexchange.com/questions/61862/…

comment Summarizing data on ArcGIS 10.1
@ChrisW It's historical - ARC/INFO which became ArcInfo Workstation had a tool called FREQUENCY so when the ArcGIS Desktop architecture came along ArcInfo (which became Advanced) level license users expected to find a similar tool. Summary Statistics is the superior tool of the two. +1 for your now comprehensive Answer.

comment Generating Custom Map image using Python with small installation footprint?
Welcome to GIS SE! As it stands I think your Question is too broad so to try and get it on-topic quickly I think the first edit you should make to it is whether you are trying to develop a desktop, web or mobile mapping solution.

comment What program is used to create this?
@blah238 ArcPy and DDP were both released 30 June 2010 so working backwards they would have been well into alpha (if not beta) during 2009 which I think would at least place them in the hands of Esri Professional Services (if they were involved). In any event DDP did not come out of a vacuum so the map book also looks like it could have been the work of PLTS' MPS Atlas. I suspect the asker (unless a map historian) is more likely to be interested in how to produce such a map book today.

comment Geoprocessing>Merge and arcpy.Merge_management() producing different results?
You should be able to copy/paste the code from when you "manually create a merged dataset using Geoprocessing > Merge in the ArcMap program" by going to the Geoprocessing | Results window and using Copy As Python Snippet.

comment Summarizing data on ArcGIS 10.1
I think you can also do this using the Summary Statistics (Analysis) with two case fields, which only needs a Basic level license.

comment projections Basemap and pyproj
Welcome to GIS SE! One of our protocols is to ask only one question per Question so would you be able to use the edit button to revise the second one out and then research/ask it separately, please?

comment What purpose do service definition packages serve?
There is no more to my Answer. Your Question asked the purpose of Service Definition files yet made no mention of the Help about them which would seem the logical starting point to try to learn that.

@jpmc26 I think you should revise your Question to focus it on that.
