landuse=residential classifications: There are several different that could fall under this... single-family, townhomes, apartments, high-rise apts/condos, mobile homes, etc.

A clearer definition of the difference between landuse=commercial, =retail and =industrial. Lots of offices are considered in zoning as 'light industrial' and called 'industrial parks', as opposed to 'heavy industrial', traditional industry with smokestacks and factories.

Fraternal lodges/meeting halls: Still lots of these around, though many of them are quite old, not just the buildings, but the average age of the members.

Towson, MD overview and the lack of planning

Posted by mdroads on 4 May 2011 in English (English)

Noticed (after working in the area over 8 years) just how anarchic the planning is in Towson, MD. It's the unincorporated county seat of Baltimore County, and has old original houses next to multi-story office buildings. Most of the original housing survives west of Bosley Avenue, and many original structures are to be found as businesses/bars/stores on York Road. Out east of town on Joppa Road, the houses are zoned commercial for miles out. East Joppa is a major route out on the east, but West Joppa, though more important a few blocks west, sneaks through that first western block as a back alley service road for businesses on Allegany Avenue.

The town's WWI monument was dwarfed by what's now the Towson Circle retail complex, to the immediate southeast of the traffic circle. Towson Commons to the south has become a retail white elephant, to the extent their full potential was never reached. Towson Circle features a Barnes & Noble and a few other stores, and Towson Commons is mostly offices and a multi-screen cinema after the Borders bookstore left. Only one or two stores survive along ground level on Pennsylvania Avenue (AKA Sushi Alley).

All said, the landuse=tag makes an interesting hodgepodge in these places. Several of the adjacent tall buildings are landuse=commercial next to =residential. Lots of parking to be accounted for, all of it guarded jealously. I'd like to find elevation data for the taller buildings, to make 3D analysis possible.

Pittsburgh TIGER cleanup

Posted by mdroads on 22 April 2011 in English (English)

Like the other counties mentioned earlier, Alleghany County, PA (containing Pittsburgh) is another poor TIGER specimen. To complicate things is the hilly environment which narrows streets and also streets in TIGER which are actually pedestrian walkways or, more often, staircases.

I began my Pittsburgh TIGER cleanup on the south slope near Mount Washington, and now on the north slope (Spring Hill, East Allegheny, Millvale). In the interval were edits on the Hill District from the Civic Arena east to Herron Hill, and the Allegheny waterfront between 16th and 40th Streets.

Dirty TIGER in PA, MD

Posted by mdroads on 13 April 2011 in English (English)

The TIGER data in York County, PA was horrific. York City and Lebanon were completed some time ago. Just completed Red Lion, Dallastown and Yoe (that's a real place). Back in Maryland, bad early TIGER data is found in Anne Arundel, Garrett and Queen Anne's Counties.
