New York Central’s West Side Freight Line (NY)
Three kmz files containing georeferenced images of Bromley and Sanborn plates that cover Manhattan’s West Side Freight Line and environment at different times before and after construction of the High Line. All reference images are included in the file, not downloaded via network links, so that user can edit the images and operate the file offline.
File opens to display only a key to the reference images. Image loading works best if user turns on the images individually, a few at a time, and waits for those to load before turning on more images; attempting to load all images simultaneously by turning on the folder that contains them will possibly crash Google Earth. Opacity adjustment works best when applied to the folder containing the images rather than individually to each image.
Peru Railways
Kmz map of four railway systems in Peru: FC Central Andino, PeruRail, Southern Copper Corp, and FC Tacna-Arica. Includes all current main and road tracks, some secondary and yard tracks, and abandoned tracks of predecessor, tributary, and other related systems.
File opens to display only objects that represent railroad facilities and structures. For visual clarity, certain other features do not display on file open, but these can be displayed manually by clicking the relevant folders in the file’s internal folder structure.
These features include:
- Labels, including stations and bridge / tunnel designations.
- Images, displayed as georeferenced thumbnails with a link that will display online content within Google Earth when the link is clicked. Of particular note is the photography of Jean-Marc Frybourg, which comprises an essential visual record of railroading in Peru in recent years; view his work at www.RailPictures.net.
- Engineering analyses, showing grade and curvature calculations of select parts of certain lines. Of particular note are the engineering standards of the Pachitea line, which suggest that the project was much greater in scope, scale, and vision than published sources have described.
- Datum diagram, found in folder “Peru railways>meta>datum diagram”, shows the date of the aerial imagery against which the objects and placemarks were originally drawn.
Corrections and comments are encouraged; find author contact information in the “meta” folder. Check back for updates and additions.
