In some cases, there may be a map display that only needs to be accessed (loaded), or you may need to limit the zoom level of the map, or you can only make the map zoom in depth between the 5--10 level. To implement these functions, you need to implement them by customizing the Mapmode. This article will introduce you to the common methods and techniques for implementing map access restrictions through custom mapmode. First you need to understand the

5. custom tile Source 1. Use locationrecttilesource to customize the BIND source with quadkey Take the Bing online map as an example. Load the Bing map (Simplified Chinese) near Hainan in the control ). First, analyze the URI of the tile System of Bing map. Here we will use the developer tool provided by Internet Explorer as an example: Through analysis (how to analyze ......) We can see that the format of the tile system URI of Bing map (Simplified

When talking about the default control and gmap2 settings on the map, I mentioned the Google map local search bar control. It is very easy to add this control to the map, you do not need to call gmap2.addcontrol (). You only need one sentence: Map. enablegooglebar (); In this way, you can add this search box in the lower left corner of the map and replace the original Google logo image. Currently, you can use this search box to search for two types of data: 1. Place Name; 2. Commercial data prov

Google map defaults to the Gmarker, you can only use the picture can not use text. But in practice, we inevitably need to mark text messages on the map. such as place names. The Google maps API allows us to implement custom Gmarker subclass Labelmarker by extending Gmarker. 1 google.maps.LabelMarker = function (latlng, options)2 {3 this.latlng = latlng;4 This.labeltext = Options.labeltext | | '';5 This.lab

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

(7): Tile System for Bing Maps. there are simple application examples for TileSystem, and two blog posts about Tile System of Bing Maps in detail. In the development of Bing Maps Silverlight Controls, there are multiple ways to implement custom TileSource. You can directly inherit the TileSource built in Bing

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 men
