geocoding

I'm trying to make a small application that takes a city & state and geocodes that address to a lat/long location. Right now I am utilizing Google Map's API, ColdFusion, and SQL Server. Basically the city and state fields are in a database table and I want to take those locations and get marker put on a Google Map showing where they are. This is my code to do the geocoding, and viewing the source of the page shows that it is correctly looping through my query and placing a location ("Omaha, NE") in the address field, but no marker, or map for that matter, is showing up on the page: function

I have a table with a POINT geometry field. I enter latitude/longitude points into it like this: INSERT INTO table( point ) VALUES( POINT( lon_value, lat_value ); Sometimes I do not have lat/lon values to enter. I am unable to enter a blank, a NULL, or an empty POINT() ... since POINT(0,0) is actually a location on the globe, that won't work either. What is the solution here? I would use coordinates of North Pole INSERT INTO table( point ) VALUES( POINT(0.0000,90.0000); If the actual coordinates of the pole may be an issue i would change the lon value from 0.0000. 来源： https://stackoverflow.com

Where in the Google Maps API docs can I find a table explaining the accuracy values of Geocode lookups? Has the range of values changed in between V2 and V3? John Himmelman Here are the Google Maps API Docs. It contains a table with accuracy values... http://code.google.com/apis/maps/documentation/reference.html#GGeoAddressAccuracy Constant | Description 0 Unknown location. 1 Country level accuracy. 2 Region (state, province, prefecture, etc.) level accuracy. 3 Sub-region (county, municipality, etc.) level accuracy. 4 Town (city, village) level accuracy. 5 Post code (zip code) level accuracy.

I have two devices. One is HTC WildFire S and other one is HTC 1V . I used the Geocoder.getFromLocationName() in my application. It is running successfully in the HTC wildfire S . But in the HTC 1V i got the following error. why it's came? How can i solve this? please can anybody help me. Code Geocoder geoCoder = new Geocoder(getBaseContext(), Locale.getDefault()); //s is the address List<Address> addresses = geoCoder.getFromLocationName(s, 5); //Here i got the following Exception.

I have several data frames in R. The first data frame contains the computed convex hull of a set of lat and long coordinates by market (courtesy of chull in R). It looks like this: MyGeo<- "Part of Chicago & Wisconsin" Longitude <- c(-90.31914, -90.61911, -89.37842, -88.0988, -87.44875) Latitude <- c(38.45781, 38.80097, 43.07961, 43.0624,41.49182) dat <- data.frame(Longitude, Latitude, MyGeo) The second has zip codes by their latitude and longitudinal coordinates (courtesy of the US census website). It looks like this: CensuseZip <- c("SomeZipCode1","SomeZipCode2","SomeZipCode3","SomeZipCode4"

I'm working on an idea for a service that uses geocoded data (lat/lng) form a US address. Google maps API v3 has been awesome, until I read the terms of service and acceptable uses a little closer. The problem is that the terms seem to prohibit use of the maps API for any commercial use where the site is not freely accessibly to the public, such as a subscription based service. The alternative offered is Google Maps API Premier, but at $10,000 per year minimum, it's just not possible at this time. Same goes for services offered by Yahoo! and MS - initial fees are small for enterprises, but for
