Streetcars and Spatial Analysis.
What are your proposals for streetcars and or trolleybuses in Brooklyn and New York City? Here past trackage maps are presented and analyzed in todays environment. Geospatial analytical methods are discussed regarding new routes.

Several of my last postings dealt with the ease of creating a watershed map using ARCGIS on-line vs. the difficulty of doing it several years ago in GRASS. One blog that deals with streetlamps and New York and various forms of Transportation (Forgotten NY) had a posting on the mysterious and perhaps haunted Chamber Street subway station at Chambers and Centre Street Manhattan, under the Municipal Building. That station has what is called a "water condition" and the site where the Municipal Building is located was once the site of a pond or some sort of collect pool, according to old maps. I ran a watershed analysis in ARCGIS on-line and the results are above for a focal point of Chambers and Centre Streets. The watershed is shown bounded by the red line.. It is interesting to note that in the bounded region, there is a park called the "Collect Pond Park" and is one source perhaps of the water. The range was set at 1000 feet. Larger ranges over 2000 feet creates a watershed that goes to Brooklyn, which is an impossibility because of the East River.
