Data Description and Usage
This dataset contains line data describing the shoreline landslide risks along the Maine coast mapped at a scale of 1:24,000. The Maine Geological Survey used this dataset to produce the Coastal Landslide Hazards Maps. The landslide hazard is given by line data in the HAZARD field describing the internal stability of sediment bluffs along Maine's shoreline. The landslide hazard is classified by one of the following: the bluff is the site of a past historical or photo-interpreted landslide (RPH), the bluff has an elevated risk of a landslide based on field observation (RF), the bluff has an elevated risk of a landslide based on aerial photo interpretation, but needs field assessment (RA), there is no landslide potential (BN), the landslide potential is unmapped or undetermined (X).
Data Disclaimer
The digital data may not include information from the most recently published coastal landslide maps. This data will be updated periodically but may be out of step briefly with published maps. The user should check the source attributes associated with the coastal landslide data lines and verify that the digital data reflects the current published map for the quadrangle. The user can view the most recently published maps or check the source for the cited open-file map in the Maps and Publications Search by searching for the open-file number (e.g. 04-93) in the publication number field.
