Basic concepts of location anti-Encoding
Location encoding is to convert longitude and latitude to specific location information
After ios5.0, use the clgeocoder class for anti-encoding. Before ios5, use the mkreversegeocoder class for anti-encoding.

I. Function enhancement:
Supports Silverlight 4 and Silverlight 5
Provides a project template for Silverlight 4 and Silverlight 5
Support for new service types and capabilities in ArcGIS 10.1 for server
Change layer rendering, Layer Sequence, or dynamically add layers in map service
Generate data classification information for layers in the map service on the server side
Use the enhanced query option to sort the results and generate statistics

request, get the current city name, for example: http://maps.googleapis.com/maps/api/geocode/json? Latlng = 22.5329294, 114.019329 sensor = true. We can replace the latlng parameter with the geographical coordinates obtained by the mobile phone to obtain the city name. Although it is more troublesome than the Baidu jar package, but it is also the most primitive method. When we access this website through the webpage, we find that a lot of data is re
When we want to implement the function in the app: Enter place name, code for latitude and longitude, realize navigation function. So, I need to use the Geocoding feature in the native map, and in the core location, it includes the positioning, geocoding (including the anti-coding) feature.Import in File#import Geocoding:/** geocoding */-(void) Geocoder { clgeocoder *geocoder=[[clgeocoder alloc]init]; NSString *addressstr = @ "Guangdong province Shenzhen Bao ' an district";//locati

Recently, the project needs to query the specific address and region by latitude, through the query network resources, found that most of the provided to get the specific address of the region or the name of the city is not very good grasp; I got myself A:
Copy Code code as follows:
WebClient Client Objects
WebClient client = new WebClient ();
String url = "http://maps.google.com/maps/api/geocode/xml?latlng=" + Latitude + "," + Longitude
need to add controls like "Toc" and "Overview", you will also create these anaged-beans in Context-attributes.xml.
Ags-functionalities.xml: In Ags-functionalities.xml, you created Managed-beans for the different features of the ArcGIS server:
Agsmap: A managed-bean that represents the map function of the maps control
Agstoc: A managed-bean that represents the TOC function of a TOC control
Agsoverview: A managed-bean that represents the overview function of a overview control

$ ("#baidu_geo"). HTML (latlon+ "address location fetch failed");});
Then look at Google Maps interface interaction. Similarly, we will send the latitude and longitude information through the Ajax way to the Google Map interface, the interface will return the corresponding provincial urban street details. The Google Maps interface returns a string of JSON data, which is more detailed than the return of the Baidu map interface, and we can display the required info
We can use the Geocodemodel in the Ubuntu SDK to GeoCode. For example, we give a place name, through the Geocodemodel to query the location of the specific information, such as longitude dimension, street information and so on. In today's article, we use a simple routine to show how to query a location.
As described in our API documentation:
Geocodemodel {

Why does GOMS need to be used?
GOMS can objectively record how users perform operations in the form. It also provides scientific analysis methods for complex forms filling processes.
It provides a relatively effective calculation method. In the process of testing different versions, it can simply compare the efficiency of the form design scheme.
Through GOMS, you can obtain credible scientific data to prove the efficiency of f
