Maptime PHL Meetup 5/30/15

Maptime PHL is holding a special event on 5/30/15 about mapping food resources in OpenStreetMap.


Our second meetup for the month of May is on a special day,Saturday, because we have some special guests in town to lead the session.

Sterling Quinn, a PhD student at Penn State’s Department of Geography, along with a few other folks from the department are traveling all the way from Happy Valley to teach us about the relationship between OpenStreetMap (OSM) and Philly food resources.

Following a presentation by Sterling about his research on this topic, we will spend the rest of the event adding local food related resources to OSM as well as improving the data which exists already.

As always, no prior experience necessary. simply an interest in maps and learning new things! so mark your calendars, set aside a few hours of your Saturday afternoon, and let’s map and learn together.

for a sneak peek at some of what we’ll be discussing, you can also check out this OSM 101 presentation from our first ever meetup and find other OpenStreetMap related info on the maptime lessons and resources page.

Food and drinks provided by Azavea, our super cool and awesome sponsor.

note: MaptimePHL events are Bring Your Own Laptop (BYOL). If you would like to attend but bringing a laptop is an issue, contact one of the organizers via email – philly@maptime.io – and we will find a way to make it work.

Explore Harrisburg in 1900: An Interactive Map of Buildings and Population

Super cool use of GIS and historical census records. Making history come alive!

Digital Harrisburg

The Digital Harrisburg working group is pleased to announce a beta version of an interactive map of Harrisburg in 1900/1901 hosted at ArcGIS Online. This map and the data it contains was developed as a collaboration between faculty and students at Messiah College and Harrisburg University of Science and Technology. The  Historical Society of Dauphin County generously provided JPEG scans of the entire 1901 Harrisburg Title Company Atlas (the layer visible as the historical map of the city) and Ancestry.com provided access to the United States census data records for 1900. Working from the census data, Messiah College students created a complete database of the population in 1900, while GIS students from Messiah and Harrisburg University created building polygons and individual census record points in GIS mapped to the level of individual properties.

What you can do with the site:

The interactive website offers a high-resolution map of…

Another Introduction to GIS

Nice summary of what GIS is. There are many definitions out there.

Texas A&M Geoservices

There are several definitions used while explaining geographic information systems (GIS).  One of the most popular definitions for GIS is “a computer-based system to aid in the collection, maintenance, storage, analysis, output, and distribution of spatial data and information. (Bolstad)”  GIS helps us gather and use spatial data;  it is concerned with absolute and relative location of features (the where) and it’s concerned with properties and attributes of those features (the what).

GIS quantifies locations by recording their coordinate positions on Earth (latitude/longitude).  GIS tools are essential in business, government, education, and non-profit organizations (Bolstad).  It helps us identify and address environmental problems by providing information on where the problems occur and who are affected by them.  Using GIS we are able to identify the source, location, and extent of environmental impacts.

Advances in three key technologies have helped aid in the development of GIS; imaging, GNSS, and computing.  Cameras…
