Last month, acnchen, Business Development Manager of Bing (Bing Maps) Greater China, published an article titled loading other Maps (Google satellite Maps, etc.) in the Bing map SilverLight control, it details how to load Google satellite maps. This article is similar to this article. In addition to Google satellite

As described in the first article of this series, developing Bing Maps based on Silverlight requires a development Key in addition to the development environment. What is this Key used? The Silverlight control is an essential parameter for map rendering. It can be understood as Microsoft Bing Maps, which is an authorization Development Key activated by users, this article attempts to use a simple example dr

A few days ago, the project used network maps, mainly Baidu maps and search maps, or sogou maps and Google Maps. The search scope is mainly in Beijing urban areas, and a bit is used in the suburbs. The advantages and disadvantages are summarized as follows: 1. Google

surface details of the polygon facing the screen are enhanced, rather than the whole model. Therefore, the performance cost is not as high as that of direct upper mode. In comparison, the displacement Paster has no flaws in the effect, but it does not have any disadvantages. First, hardware requirements are high. shadermode3.0 must be supported, because Sm3 can be used for texture operations at the vertex stage. At the same time, mosaic consumes a lot of performance. However, in terms of GPU pr

future dx10 uniform rendering architecture. Compared with all the concave and convex pasters we have introduced, displacement pasters are the only way to change the geometric shape of a polygon surface. Compared with the light tracing algorithm to be introduced later, the performance consumption of this algorithm is not dominant, but it is actually more reasonable. It gives the screen more special effects. What's more interesting is that it does not conflict with other pixel-based concave and c

The OSM (OpenStreetMap-Open Street Map) service is an implementation type that allows you to publish your own map data images, the motive behind the establishment of open street maps is to create and provide geographical information (like street maps) that can be freely used to everyone who wants to use them, just as free software gives users freedom, this article describes how to use the map service releas

The function navigation provided by Bing Maps Silverlight Control is very powerful. In terms of design, it provides great support for extensions and provides commands and buttons that can be extended and directly used by many users, if you are not clear, you can view the article "Custom navigation bar" that I wrote earlier. However, compared with the functional navigation menu provided in DeepEarth, the menu is not so bold and dynamic. I personally pr

As you know, Google Maps is more and more popular around the world. Is it possible to integrate Google Maps into my MapGuide Enterprise Fusion viewer as base map? Yes, it is! As MapGuide Fusion viewer uses a subset of OpenLayers, it allows us to access to the underlying OpenLayers API. in this article, we will show you how to integrate Google Maps into our exist

I believe that most of the users who use Bing Maps for development have seen the following picture: when we develop Bing Maps, a prompt error occurs when the Development KEY is incorrect, resulting in user authorization verification failure. 　　　　　　　　 The disadvantage of using Bing Maps Silverlight Control is that it uses the online map data provided by Microsoft

The Bing maps provides a set of WCF map services that we can use to facilitate geographic search and other related functions in our application systems. They are geocoding services (geocodeservice), geo-imaging Services (IMAGERYSERVICE), Routing function Services (Routeservice), and geographical search services (Searthservice). I. Geographic coding services (Geocodeservice) The Map Coding service provides the function of matching the map address (bo

How can I use Google map data in the Google Maps API? This is almost the most common question I have heard about Google Maps APIs. As we all know, Google Maps does not have a detailed map of China. In China, we only have a unique Google map website that provides a detailed map of China. The reason for this situation has not been officially explained by Google a

Development and application of "Silverlight" Bing Maps Three: Offline development of Bing Maps Silverlight control I believe most of the friends using Bing Maps have seen the following picture, when we are developing Bing maps, it is wrong to create a bug in the following illustration that the user authorization faile

As follows: JavaScript code: New encapsulated version:VaR map; var geocoder = new Google. Maps. geocoder ();/***-25.363882, 131.044922 * initial map */ Function initialize (LAT1, lng1, zoom, canvas_div ){ VaR mylatlng = new Google. Maps. latlng (LAT1, lng1 ); VaR myoptions = { Zoom: Zoom, Center: mylatlng, Maptypeid: Google. Maps. maptypeid. Roadmap } Map =

Bing Maps Advanced Series Five: Deepearth minimap control for Bing Maps extended Mini Map The Bing Maps Silverlight control provides us with a simple and convenient development model, but there are a number of drawbacks, such as we want to implement a mini map feature, and there is no such built-in controls for Bing map Silverlight. But there's no need to bother

Basic Development of Baidu maps and Development of Baidu maps Due to the needs of the project, I recently encountered Baidu map Android development and encountered many problems. I believe many bloggers have encountered these problems. Now I will share my practical experience with you. To develop Baidu maps, Step 1: first log on to the Baidu map open platform and

Use SVG to draw Hunan maps and svg to draw Hunan maps The project has the need to use SVG to draw Hunan maps. Now I will write my own production process for your reference. 1. First, prepare a map of Hunan (only the border lines of each city ). (The image is preferably PNG, except for the map) 2. Prepare the SVG editing tool SVGDeveloper. 3. Import the image to t

Some time ago, due to work reasons, the study of Google Maps tile-related operations. Know the latitude and longitude of a point and the map level, get the URL of the tile where the point resides; the URL of a tile is known, the upper-left corner of the tile is computed, the latitude and longitude of the tiles are known, and the pixel values on the world map are computed for a point latitude and longitude and map level.1, know the latitude and longitu
