Wetlands Determination

This example uses the GetGeocode functional component, and illustrates one of the interactive mapping features you can implement using the full parcel geometry results from the GetGeocode functional component. Here, the address, city, state and zipcode of a location are passed into the geocoding engine using GetGeocode, and depending on the type of result a wetland determination is made. The result will be either in a wetland, out of a wetland or undetermined if wetland data does not exist for an area.

layer = new Dmp.Layer.TileLayer("wetland", "SS", {
antiAlias: true
});
layer.addChild("poly", "SS.Hazards.Wetlands/Wetlands", "", {
zIndex: 2, zoomRange: {
min: 15, max: 19
}
});
map.addEntity(layer);


// add the parcel layer to the map
layer = new Dmp.Layer.TileLayer("Parcel", "SS", {
antiAlias: true
});
layer.addChild("Parcels", "samplesite.dmp/ParcelTiles", "", {
zIndex: 2, zoomRange: {
