Can Pixels Solve the Area 51 Mystery at 76 Street?

In my previous posts, I presented in somewhat limited form, the 76 Street and Pitkin Avenue mystery.  Trackmaps show the presence of a four track subway station under that location.  At street level, there are no man hole covers or ventilation gratings hinting that a subway station lies below.  There are not too many people left who remember and are available to reveal eye witness reports regarding the construction.  Some of the signal boards show the 76 Street station, some do not.  The image above which comes from the internet, shows what appears to be 76 Street station.  Presently, in the New York City subway system, there is no 76 Street Station.  The picture appears to be not true, because in 1948, supposedly the date in which the station openned for a short time, the shown R-10 class subway cars did not have this white and blue strip paint scheme.  The transit authority has been quiet regarding this and will not allow anyone to go beyond the bulkhead and take a picture.  Can pixels solve the mystery?

   In my previous posts, I took a 1951 aerial photograph in bitmap format and added it to my ARCGIS ESRI map.  Since I do not have all advanced functions, such as spatial analyst, I could not rubbersheet the image to the correct x and y coordinates.  I tried my best.  The aerial photograph shows that at a few blocks to the left of the station, on Pitkin Avenue, the surface of the street appeals lighter.  Is this due to new asphalt or boards covering a construction pit?  At any rate, the area at 76 Street and Pitkin appears normal and the building footprint (not shown) appears normal.  If I had a better copy of ARCGIS, I would convert the bitmap file to raster and do a raster analysis.

My questions to the public are:

Are there any free programs on the internet that allow for bitmap to raster conversion and can analyze raster files?

Do you think in general that raster analysis can help here?  I am new at this and I would like some opinions from the public.

Respectfully,

If you came to this blog, you probably love streetcars and perhaps trolleybuses as much as I do.  I live in Brooklyn, New York which is part of New York City.  The last streetcar that was city owned ran in October 1956 and I remember it, although I was in the first grade.  Trolleybuses, as someone said, is transit's stepchild, also ran in Brooklyn.  I remember them on the Cortelyou Road route in Flatbush.  The last trolley bus ran in Brooklyn in July, 1960.   As you probably know, streetcars, also known as light rail, are coming back all over the world including many cities in the United States.  Unfortunately, they do not appear to be coming back to Brooklyn or in the other boroughs despite the efforts of various groups such as Vision 42 http://www.vision42.org/ or Brooklyn Historical Railway Association.http://brooklynrail.net/.
       About a year ago, Yonah Freemarkhttp://www.thetransportpolitic.com/ wrote an interesting blog asking the theoretical question:  If streetcars did come back to Brooklyn, what would that system look like?  He produced a great map that stole my thunder.  I will comment on his map later but for now, I would like to present the aims of this blog:

1)  If streetcars came back to Brooklyn, what routes would they run on?  What would a map of these routes look like?  Would the route be the same as in 1956?  What routes do you think should come back and why?  How about streetcar and or trolley bus routes in other parts of the city? 
What do you think about "peak oil" and electric surface transportation and how about trolley boats and trolley trucks in a limited oil environment?  We all know that electric surface transportation is good for the environment.  Perhaps we can show this using maps.

2)  How can I make better maps using ESRI ARCGIS to display this information?


3)  How can I use some of the geoanalytical techniques available in ARCGIS for making better maps that show proposed streecar lines?  For example, should new streetcar routes be established in neighborhoods that are far away from existing subway/bus lines and have light/heavy concentration of population?

4)  If my edition of ARCGIS cannot do not regression analysis, can I use Geoda or "R" to do analysis for proposed routes?  What methodology should I use? and finally:

5) Although not streetcar related, what geospatial /analytical techniques can I to study isolated communities that receive a form of social services if I have demographic and other type of census data including rapid transit line data?  What software do you suggest other than ARCGIS, Geoda, or "R" can I use to study isolated populations?
