Qgis 3d Map

|

I am absolutely fascinated by the QGIS 3D Mapping feature and the neat maps I can produce with it. I finally figured out how to turn on the labels – it’s just a switch in the advanced section but now all the labels are at ground level and are most readable when the viewer is set due north.

Additionally, while raster maps are very fast in the 3D view the same can’t be said about complicated vector maps I often make up for hiking, especially with the labels turned on. Maybe I’ll have to export the 2D maps as georefrenced rasters then load them into a new project.

Another thing I discovered is that I can use both the state’s aerial photo and digital elevation model WMS feeds – at least when I have internet – with the 3D mapper to make beautiful, drone like shots. I only played with that briefly when I was at my parents house but I am planning on going to the library tomorrow to do more.

A 3D “Drone” Tour of the Eastern Albany Pine Bush in 1952

Our tour starts at Fuller Road and Western Avenue overlooking what is now Stuyvesent Plaza and I-87/I-90 Thruway. We head west on Western Avenue, passing along the current site of Crossgates Mall and Lawton Terrace (under development).

We head up old Rapp Road to the former Rapp Road Hog Farm and the Historic Rapp Road Neighborhood. We look east towards the Crossgates Mall site, then head northeast over several large dunes, now SUNY Nano Tech and Thruway to Rensselear Lake.

We head northwest over Upper Rapp Road and the landfill site and then follow the Kings Highway up to where it meets Old Karner Road and Overlook Dune then turn out and head south towards the Upper Kiakout Ravine on Old Karner Road. We head northeast across Blueberry Hill East and 350 Washington Avenue site, following Old Lydus Street (now Washington Avenue Extension) back to Rapp Road, then south on Rapp Road.

We follow Rapp Road south to Western Avenue, then turn around and look northwest, pausing briefly at current landfill site, then pull back on the frame to see a portion of the Pine Bush that is developed today, between former Lydus Street (now Washington Avenue) and what would become the Thruway and the landfill.

Dry cleaners did not begin using perc until the early 1980s, when, in an ironic twist, they were forced to do so by the U.S. Office of Safety and Health Administration. Prior to that time, dry cleaners had used a hydrocarbon-based product called stoddard. Though stoddard is relatively benign environmentally, it is extremely volatile and has a very low flash point. Stoddard had, in fact, been the primary culprit in a number of serious fires. Chlorine-based perchloroethylene, by contrast, is not especially volatile.

What OSHA did not realize was that perc has the unique ability to penetrate concrete. Moreover, when freed it quickly seeks the lowest point in its environment. As a result, the chemical rapidly descends through concrete floors into the soil and eventually into the groundwater. Once there, it flows wherever the groundwater flows.

Perc was found to cause cancer not long after it was introduced to the dry cleaning industry.
