PASDA GIS Data Reminder


As the Oil and Gas boom has hit Pennsylvania, GIS data is a prime commodity in obtaining permits and generating needed concept plans. A major source is the Pennsylvania Spatial Data Access (PASDA) clearinghouse. And I quote:

Pennsylvania Spatial Data Access (PASDA) is the official public access geospatial information clearinghouse for the Commonwealth of Pennsylvania and has served for fifteen years as Pennsylvania’s node on the National Spatial Data Infrastructure, Geospatial One-Stop, and the National Biological Information Infrastructure.
PASDA was developed by the Pennsylvania State University as a service to the citizens, governments, and businesses of the Commonwealth. PASDA is a cooperative project of the Governor’s Office of Administration, Office for Information Technology, Geospatial Technologies Office and the Penn State Institutes of Energy and the Environment of the Pennsylvania State University. Funding and support is provided by the Pennsylvania Office for Information Technology,Geospatial Technologies Office. In addition, PASDA also receives substantial support from the Pennsylvania State University.

So there are tons of great data types to choose from, depending on your needs. But there is one question I often get asked and rarely remember the answer. For some reason, some data is formatted to be in the coordinate zone Antarctic98.LL, which refers to the Lat Long grid for the Australian Antarctic 1998 datum. Of course, this is not correct. So the first place to research is the metadata. Read more of this post

Parcel Ownership for Oil & Gas Pipelines, Part 1

Living in Pennsylvania, the Marcellus Shale has had a positive business impact on firms in and around the area. With that, the Oil & Gas industry has brought a new way of creating design documentation than we have been accustomed to doing in the past. For instance, the pipeline will stretch many miles and cross many properties. And as is often the case, easements will have to be obtained. So along the pipeline concept plan will have to be some documentation of property impact.

Along comes the idea that in the profile, we add a band indicating the station at which a parcel line crosses the alignment. And, in between those “crossings,” we indicate who owns that parcel.

So, how do we do that?
