ELF Transport Networks (TN) Iceland is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE-compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview. The transport layer contains both line and polygons. The linelayer shows the transport network but the polygon layer contains the airports. Encoding: INSPIRE version 4

This is a linear footprint dataset for the Castle region of Alberta. This dataset was created to support spatial analyses of linear footprints in the Castle region for the Alberta Environment and Parks report entitled 'Ecological Response to Human Activities in Southwestern Alberta: Scientific Assessment and Synthesis' which can be found at https://open.alberta.ca/publications/9781460135402 . The dataset compiles information from four of the most current Government of Alberta and public linear footprint data sources. All linear footprints are grouped into five categories using attribution from input data sources. These include: paved roads. gravel roads. unimproved roads, unclassified roads, and truck trails. pipelines and powerlines. and cutlines and trails. Please note: this legacy dataset will not be updated. For questions regarding the data, please contact AEP.Data@gov.ab.ca.
