The arcgistiledmapservicelayer layer in ArcGIS API for Silverlight inherits from tiledmapservicelayer. If you want to implement your own cache map layer, inherit it and reload the gettileurl method. ArcGIS API for Silverlight internally calculates the current access scaling level, slice two-dimensional number row, Col. These parameters are exposed to the gettileu

Summary: ArcGIS Web maps are composed of basemaps and a set of related layers that users can interact with to perform a meaningful task. These maps are available to a wide range of users and include multi-scale basemaps, business layers for a specific audience, and information pop-ups to help users gain insight into the features of interest. These maps also support visualization, editing, analysis, and time functions. They are the foundation of WEB

1. Map Printing is an important function of GIS. It can be said that without Map Printing, it is not a complete Geographic Information System. 2. Map Printing points: trapezoid printing, administrative area printing, and cutting printing. 3. ArcGIS provides many layout printing tools. After all, it is made by foreign

The API has changed a lot since the ArcGIS API for JavaScript 4.X version was upgraded. which supports the Webearth display, mainly through the Esri/views/sceneview implementation. In the new version, the default is to load ESRI's own map. If you want to load additional maps, you can implement them by extending Basetilelayer. For example, the latest version loads the demo of the Gould

Here's a series of ways to set the map extent and how to get the map extent.If you do not set the map extent when you initialize the map, the default settings information will be used, which will be the extent of the map displayed when you last saved the

Recently, I have studied the implementation of the ArcGIS Server Web ADF (9.2) Thematic Map as follows (taking the bar chart as an example, the pie chart is similar to the histogram). I hope it will help you! // Obtain the layer ID of the topic. .......... Int layerid = 3; // Obtain the attribute name list of the topic graph analysis element.
