Editor's Notes
- Geocoding.
- More usage with Bing
- The service is built primarily using the GeoNames Dataset that anyone can contribute to and is free to use.No addresses
- 3 categories for coverage description.Only 15 countries in the top advanced category.Navteq data under the hood. No idea on how often they will update.
- Throw 62 king street at itTop result is in NY.
- Can feed in the sourceCountry.Perhaps lock your application down to just search within Australia*Finds King Street in WACould have locked it down in the code of your web app to State of Victoria instead.
- We can include the city name into the search, and we could hardcode this into our Application*Finds it.
- A better approachTake the extent of your map from your web app and feed it in as an input to the geocoder.
- GetBbox from current map, maybe extend the extent a little as well *Finds it fine.Could extend this logic:Expand the extent, and return multiple results to end-user, based on both the relevance and proximity to the centre of the map.
- Drunk people typing in things wrong.Can still find results, they just return lower candidate score.100 is perfect match, lowers based on spelling or matching.
- Score is useful for your web apps.If only one result found and above 95 = zoom to it.*If >1 result found, and no one score is above 95, prompt user to choose a location.ArcGIS Online does not do this.
- 3 categories for coverage description.Only 15 countries in the top advanced category.Navteq data under the hood. No idea on how often they will update.
- If your searching for regions like postcodes or national parks*Finds these fine*Instead of zooming your map to the centroid, you can zoom to the actual extent of the region.
