(1) create a simple Google map page, which can be found in the Google Maps documentation.
(2) Add reference of ArcGIS javascript API to Javascript, for example:
(3) Use WebService in the initialize () function to create a layer provided by ArcGIS online, for example:
VaR
If your site uses some of the mainstream Ajax library such as jquery or prototype, you can use Google Javascript API loader to load your AJAX library directly.
The specific approach is the following example:
Because Google uses a CDN (content distribution network) to send data to clients faster than your server, and
The following code uses the Google map API to obtain the distance between vertices ()
The Code is as follows:
Var request;Var distanceArray = [];Function getdistance (){DistanceArray = [];Var directionsService = new google. maps. DirectionsService ();For (var a = 0; a For (var B = 0; B If (! = B ){Request = null;Request = {Origin: pointsArray [a],Destination:
First introduce JavaScript API files
This API provides a total of 6 interfaces, Geoip_country_code () {Country Code},geoip_country_ name () {Country name},geoip_city () {city name},geoip_region () {Region code}, Geoip_latitude () {longitude},geoip_longitude () {latitude}.
Where the region code for Maxmind internal use of a code, the provincial provinces in ac
Mbtiles is a map tile storage data specification, it uses SQLite database, can greatly improve the reading speed of massive map tiles, than through the tile file way of reading much faster, suitable for Android, iphone and other smart phone offline map storage. For more information, please refer to: Mbtiles Mobile Storage Introduction.In the Web map introduction We see that tiles refer to their z/x/y form coordinates, on disk storage, they are usually stored in a directory with Z, x as the name,
I have not been busy with specific things recently. I just took the time to learn extjs and integrate the functions of a configuration tool originally developed by bcb6 into the existing web platform; extjs can be consolidated in practice. One of the region configuration functions is intended to integrate the previously made Google Maps. Google Maps originally used Goog
| 24 | [PNG data]
5 | 15 | 25 | [PNG data]
This table is easy to query for a particular tile: for example, the query level is 8, the column number is 116, the row number is 192 of the tile data:
SQLite>SELECTfromWHERE=8and=116 and=192; [PNG data]
Tile_data is a binary stream file that can be easily read from the Mbtiles database, whether it's a desktop app or Android or iOS app.
Here is a demo program I made with Delphi:
Cita
If your website uses some mainstream Ajax libraries such as JQuery or Prototype, you can directly use Google Javascript API loader to load your ajax library.The specific method is as follows: Because google uses CDN to send data to the client, the speed is certainly faster than your server, and the client browser cache
(gbrowseriscompatible ()){
// Start creating and operating the map
} Else {
// Define your handling of this exception here if necessary
}
Of course, in your own code, you still need to implement compatible code for different browser environments. Here gbrowseriscompatible () it only ensures that the map API class library runs in its compatible environment.
