, search services, rendering services, and route services. This application is most concerned with the search service, but if you want to guide the user or map direction, you can also use other services to expand functions. A public service (commonservicesoap) contains the common classes, methods, and attributes of the search service, route service, and rendering service, or basic utility functions. You can use the search service (findservicesoap) to locate the address, geographical entity, dime

Now I want to talk about my military standard idea.The first technology used: the front-end as language draws the military logo (actually a polygon) and forms the points of the Polygon into an XML string. Here we can also transmit objects, however, the same correspond

You can query the geographical longitude and latitude coordinates of an IP address based on the IP address. For example, in the following example, the IP address 58.192.32.1 is located at 118.777802 and 32.061699, which is the location of Nanjing University.

Reference from: http://cgi.blog.yam.com/trackback/327858 David Gelernter, professor of computer science at Yale University, proposed in 1991 that the real world be virtualized on computer screens using software, from traffic, interior decoration, and even sales and currency data, can be displayed on the computer screen with icons. Gelernter's idea took a big step weeks ago. A few weeks ago, Google and Yahoo published their results, allowing designers to more easily integrate a wide range of net

simple Ajax interface of Google Maps is quickly explained by hackers, who then mix the data to form new services. Map-related Web services have been available for some time, from geographic information systems vendors such as ESRI, Mapquest, and Microsoft MapPoint. But because of its simplicity, Google Maps ignited a fire in the world. To experience any formal vendor-supported network service requires a formal contract between the two sides, Google M

Arcgis api for flex advanced topic (2) Development of Custom Controls Arcgis api for flex only provides two controls: Navigation and ScaleBar. Describe in detail how to develop custom controls (or, maybe, I did not find them ), The following describes my methods. To control the dynamic display of the current mouse longitude and latitude on the map . 1. Define the control class and integrate UIComponent to implement the IMapAware interface. 2. Reload the createChildren function. 3. Implement the

these points are xmin or xmax, so we can remove the points on the boundary. However, there is a problem here: When we divide the data according to a certain step, the entire score may not be fixed, that is, the following situation occurs: We found that the top and right sides are not just equal. The top and right sides of the line are out of the "range". Although this does not affect the extraction of the intersection points of the river, it is not so nice. Next, let's take a look at the code

ArcGIS API for Flex is mainly built on ArcGIS Server rest API. The client has limited functions and many advanced functions are implemented through geometry service and geoprocessing service. However, some simple functions, such as getting the center point of polygon, bring up a custom window at this point. If services are used for interaction, the user experience may deteriorate. Therefore, you can write some code to implement these functions on the client. Here is the code I wrote to get the

Author: Flyingis Flex is inherently capable of asynchronous calling, so that Flex can well adapt to common functions in webgis applications. In ArcGIS Flex API, the most typical is dynamic display of geographical element information, for example, if you move the cursor over a geographical element to display the basic information of the element, the "Show InfoWindow on mouse hover" section of ArcGIS Flex API Demo is used as an example.
