Data Dictionary for: Survey grid (50 x 50 m) for conducting field-based invasive plant surveys on Tualatin National Wildlife Refuge Complex dataset Robert V Taylor Regional Invasive Species Data Manager json Tualatin Grid 50 x 50 m Geospatial dataset consisting of a 50 x 50 m rectangular grid that overlays the Tualatin National Wildlife Refuge Complex (including Tualatin River NWR and Wapato Lake NWR). This original grid was created in 2018 but re-used for this survey effort. Survey grid (50 x 50 m) for Tualatin National Wildlife Refuge Complex false Producer Defined FID Internal feature number. 1 1 ESRI FID integer Shape Feature geometry. 1 1 ESRI Shape other Grid_Name Name of the grid which consists of the year the grid was created, the size of the grid, and the refuge or complex for which it was created (e.g., Minidoka_NWR_50x50m_2020). Note that the grid name should be the same for all features in this data set. 1 1 Producer Defined Grid_Name character Grid_ID Unique ID of a grid cell (e.g., X100Y35). Note that both the grid name and grid id are necessary to unambiguously correlate the survey results to a geographic area. Note that this field was created from the X_Index and Y_Index fields. 1 1 Producer Defined Grid_ID character XY_Coord This text field contains the latitude and longitude of the centroid of the grid cell separated by a comma (e.g., 42.6503575252863,-113.469748552465) 1 1 Producer Defined XY_Coord character Surveyed This text field indicates whether a grid cell has been surveyed or not within some given time period (e.g., a year). After a grid cell has been surveyed, it is set to "yes" by the field surveyor. This field can be reset to "No" if needed to accommodate multiple years of surveys. 1 1 Producer Defined Surveyed character GlobalID This is a universally unique identifier (UUID) assigned to a record in the dataset when it is published to ArcGIS Online. 1 1 Producer Defined GlobalID UUID This text field can be set to "Yes" for grid cells that require followup to treat early detection/early response species or "No" if no followup required. Defaults to "Not assigned". 1 1 Flag_EDRR character The longitude of the center of the grid cell in WGS 1984 Geographic Coordinates 1 1 Centroid_X float The latitude of the center of the grid cell in WGS 1984 Geographic Coordinates 1 1 Centroid_Y float
