Description:

Abstract:

The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.

Purpose:

The purpose of this dataset is to identify the BCMCA planning units in which Ruppia spp. (ditch-grass) have been observed that help inform the marine feature identified at the BCMCA Marine Plants Workshop.

Supplemental_Information:

Refer to the original metadata document for data limitations and usage. Title or link is provided within source information. Data was collected and merged by target feature layer using the following data sources: 1. UBC Herbarium (Ruppia.XLS). Identifies 2 Ruppia observations. 2. rup_Durance.shp. Ruppia points were digitized based on collection work by Cynthia Durance. 3. widgeon_grass_tl. A feature class from the Subtidal_Survey feature dataset in the CRD's Harbours_Atlas geodatabase.

Process_Step:

Process_Description:

--> To prepare UBC dataset:
Converted UBC Ruppia.xls table into dbase format so that the XY coordinates stored in the records could be plotted spatially and exported as a point feature class.

Process_Step:

Process_Description:

Formatted excel worksheet for conversion to DBF. Two new columns were created to store decimal degrees: "LatDD" and "LongDD". Converted DM coordinates to DD using an excel conversion formula (can be found in many formats online). The longitude and latitude columns have the original DM coords.
Saved excel worksheets as dbase version 4. The saved dbf tables were reviewed to ensure they contained the same amount of records as original excel worksheets, and the decimal degree coordinates were tested against the shoreline trim to ensure the points were in the correct locations around vancouver island. 3 records did not have coordinates and were deleted.

Process_Step:

Process_Description:

All records were plotted and displayed in Arcmap using display XY data tool: Added the DBF table to ArcMap, right clicked, selected display XY Data. Selected appropriate Y and X field LatDD and LongDD respectively. Set the coordinate system to GCS North American 1983.

Process_Step:

Process_Description:

Turned event layer into feature class and projected data: Right click the event layer and select data, export data and saved as a shapefile. Projected shapefile using the project tool from GCS North American 1983 to NAD 1983 BC Environment Albers imported from CMN's S_EG95.shp. Converted shapefile to feature class using feature class to feature class tool.

Process_Step:

Process_Description:

Deleted 3 points without lat/long coordinate data. Deleted 2 points not specific to BC Coastal (Cache Creek & Princeton) region. Deleted one point between Tsawassen ferry terminal & Roberts bank coalport. Coordinates within the UBC Herbarium Ruppia.xls were only accurate to the degree (i.e. 49 degrees N, 123 degrees W). Carrie Robb was in direct contact with data source contact (Cynthia Durrance) and was supplied with more accurate coordinates; included within Rup_Durance.shp.

Process_Step:

Process_Description:

To Prepare Durance shapefile: Points were digitized by Carri Rob based on information received from Cynthia Durance (Nov 25/2008). Converted shapefile to feature class using feature class to feature class tool.

Process_Date: November 25, 2008

Process_Step:

Process_Description: Merged with UBC herbarium Ruppia dataset using merge tool.

Process_Step:

Process_Description:

Added 4 new fields using add fields tool: Feature (common name of marine feature identified), SOURCE_DATA (dataset shapefile name), spatial accuracy and Dataset_ID (dataset common identifier as per BCMCA dataset DB notes).

Process_Step:

Process_Description:

Populated the fields using the calculate field tool:
Feature field was calculated to Genus name of marine feature. SOURCE_DATA field was calculated using the dataset source name. Dataset_ID field was calculated using the common dataset identifier. Spatial Accuracy field was calculated using "undetermined"

Process_Step:

Process_Description:

Deleted following fields using delete fields tool: Acc #, Family, SpAuth, Subsp, Subspauth, var, varauth, Country, Province, Location, Coll #, Other Collector, Determinor, Habitat, altitude, Note.

The Select By Attributes functioin was used to select all records where [Datasource] = "". The field calculator was then used to populate the selected records for the Datasource field with "CRD Subtidal Survey (widgeon_grass_tl)". As well, selected records for the Dataset_ID field were populated with a value of "147".
