KCD Farm Plans

An interactive web map marking KCD Farm Plan parcel locations.

Process

• Farm Plans, with a link to one or more parcel table records, are joined to King County parcel GIS data, resulting in a shape file/feature with records for all parcels referenced in Farm Plans.
• The feature is converted to GeoJSON; used as input to create polygons on the map.

Leaflet APIs used:

• Map with center, minZoom, and zoom (creates map)
• TileLayer with attribution (lower right note) and subdomains (of the tile service)
• Icon with iconUrl, iconRetinaUrl, iconSize, iconAnchor, and popupAnchor (clickable point symbol)
• Marker uses JSON to create a table of data for the markers (first name, url, lat, lon)
• layerGroup creates a layer group that can be used in the Control API
• Control creates a layer control on the map

Clicking on a marker displays the Last Name on the farm plan. The name is a hyperlink that is currently pointing to a test page on the Atlas site.
