Utility Line

This data set shows utility lines that provide services for: power water communications heating fuel They include: communication lines/submerged communication lines hydro lines/submerged hydro lines natural gas pipelines/submerged natural gas pipelines water pipelines/submerged water pipelines unknown pipelines unknown transmission lines Additional Documentation Utility Line - Data Description (PDF) Utility Line - Documentation (Word) Status Required: data needs to be generated or updated Maintenance and Update Frequency Not planned: there are no plans to update the data Contact Ontario Ministry of Natural Resources - Geospatial Ontario, [e-mail] Recommendations Not for legal purposes. This data is collected with varying aerial photography dates and scales. It is a snap shot in time and maintenance of these features are uncertain.CAVEAT:Data for this information holding varies by OMNR District in terms of...-Completeness: - Concentrated surveys in one or more areas of the District. - Instances where no surveys were initiated, even though there is evidence of the value. - Instances where the value is not known to exist within the District. - Instances where attributes collected for the value will be minimal to verbose. - The data may exist only in a tabular form (files, hardcopy maps) within the District.-Accuracy: -Dependant on the value's source capture methodology. -G.P.S. coordinates vs. sketched location. -Generalized location (buffered point) vs. mapped area (polygon)-Vintage: -New vs. old value survey information for values in part(s) or all of the District.-Sensitivity: -Some OMNR Districts may consider a specific value or group of values sensitive, others may not. -Some of the values may be flagged as sensitive due to intellectual copyright. (i.e.: Professional Research). -The value may be flagged as sensitive due to its link or relation to First Nation Peoples.
