Name: Canal Alignments

Display Field: canal_name

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This dataset was created by copying the existing canal dataset (Alignments_Canal), adding in some segments from the NHD identified as canals, and removing some natural channels that are not part of any system. Lots of work was done in April/May 2017 to clean and verify the topology and direction of flow; future updates should strive to maintain or update this topology.The Canal Name field is intended to be the name of the physical ditch, like 'System D' or 'Such-and-such Lateral' and roughly corresponds to the old canal_alias field. The company_id field is a foreign key for the canal_companies table, which holds the canal company name and contact info. Join the table to label each canal by the company that owns or maintains it. The zoom_level field is a cartographic field for displaying more info at closer zoom levels. 1 is for main canals, 2, for major laterals, 3 for most laterals, and 4 for tiny one-off laterals to individual properties.The share field indicates whether the segment can be publicly shared on webmaps or given to people who ask for data.
