My Web App calculates the distance and different species of fish between a dive site and 18 shipwrecks on the West Coast of British Columbia. This app is designed to help you plan the length of your shipwreck diving adventure, as well as give you an idea about the fish you may see on your dive. It does this by utilizing open data on the BC Governments website, specifically data of Shipwreck locations, BC Fish Observations, and BC Fish Distributions, and Coastal Diving Sites.
Step 1. Click the dive sites and shipwrecks in which you are interested and make note of the dive site ID and the shipwreck ID.
Step 2. Click on the geoprocessing widget and write a SQL query to indicate the dive sites and shipwreck sites in which you are interested, using the dive site ID and the shipwreck ID. The syntax for the field names must be “DIVING_SITE_ID” and “SHIPWRECK_ID”.
Example: “DIVING_SITE_ID” = 338 AND “SHIPWRECK_ID” = 8
The Geoprocessing service will draw a line between the dive sites and the shipwrecks which are indicated. The default is the paths between dive site ID = 1 and the 18 shipwrecks.
Step 3. Run the process. You will see the fish symbols appear as a layer on the map within the buffer which was indicated. This graphic is not that important, as there are no fish observations in open water, making the fish symbols discontinuous across the dive path. The output table summarizes the different fish species which have been observed along the dive path is more interesting.
BE AWARE, A DIVE PATH MAY GO THROUGH LAND IF ITS THE SHORTEST DISTANCE.
