>Prepared BC Coastal Waterbirds Survey dataset:Imported excel worksheets "BCCWS raw data 1, raw data 2, raw data 3" from Coastal Waterbird Survey data '99-'08.xls into a geodatabase. To join tables to spatial, created new field, SITECODE, in all 3 tables. Using field calculator, populated SITECODE field with following formula: [RegionCode]& [SiteNumber]. Create one field storing date (ymd) rather than 3 fields. Populated field using field calculator with the following formula: [Year_]&"/"& [Month_]&"/"& [Day_]. To combine all 3 tables into one table, used the Append tool and appended raw data 2 and raw data 3 to raw data 1 table. Deleted "Year_" Month_" and "Day_" fields using Delete Field tool. Added 3 new fields using Add Field tool: Feature, Data_Source, Dataset_ID. Populated fields using Calculate Field tool. Feature field calculated to equal the SpeciesCode field. Standardized the Feature field naming convention to equal the common name of the marine species rather than the abbreviated species code. Data_Source field calculated to equal the name of the dataset from which data was derived. Dataset_ID field calculated to equal the common dataset identifier as categorized by BCMCA.
>Created Survey File:Added 2 new fields: Area_km2 and Density_km2. Area_km2 calculated by multiplying the shape area (m2) by .000001. Density_km2 Density field calculated using the following formula: [nbird_Total / [Area_km2]. Note: For the CDC polygons, both the First_OBS and Last_OBS fields were reviewed and if either one of these recorded months fell within the features' specified habitat, the polygon was used in order to display that the polygon was surveyed at least once.
>Created Final Processed File:Overlaid merged feature polygons with BCMCA planning units using Spatial Join tool. Tool parameter example: Target Feature = dfo_bc_2k_4k_combined.shp, Join Features = feature layer, Join Operation = Join_One_to_Many, Match Option = Intersects. To create the final processed file, summarized data by planning unit ID and calculated the sum of the total surveys, the sum of the surveys species sighted, and the sum of the density. Added a new field: AVG_DENSITY_km2. Calculated field using the following formula: [sum_DENSITY_km2] / [sum_SURVEYS_TOTAL].
